Development Strategy

　　Yuanjie Smart Water Management Platform

　　The first step is to enhance water resource operations management capabilities through the utilization of water resource operational data; the second step is to forecast long-term water resource demand and potential water resource challenges; and the third step is to ensure and coordinate the healthy operation of water resources, thereby enabling their sustainable utilization.

　　Yuanjie Water Services has developed an intelligent water resources management system that integrates functions such as information dissemination, multi-organizational data sharing, and visualized monitoring of equipment and pipeline networks, thereby facilitating cross-departmental collaboration. China’s urbanization and the achievements of urban development are truly remarkable: cities are now densely packed with towering buildings, and the application of water treatment systems directly impacts the safety and hygiene of urban residents’ water supply. As the integration of “Internet Plus” with various industries continues to deepen, smart water management has emerged as a natural response.

　　Enables real-time supervision by health inspection authorities.

　　Provide property management personnel with real-time operational status visualization.

　　Provide the government with real-time operational data for secondary water supply systems.

　　Mobile app for remote, real-time monitoring of equipment operating status

　　To better address water resource challenges arising from intense human activities and climate change—such as soil erosion, flooding, water pollution, and drought and water scarcity—and to advance water management toward greater levels of digitalization, many countries at home and abroad have, guided by the concepts of “smart cities” and “smart earth,” initiated the development of smart water systems. Smart water management has thus become an effective platform for the scientific management of water resources in numerous nations.

　　Yuanjie Water’s smart water resource management is primarily structured into three key steps: coordination, forecasting, and utilization; sharing and optimization of scheduling; real-time data collection; and systematic organization of the pipeline network.

　　We believe that smart water networks can leverage advanced communication and information technologies to guide existing water resource management, thereby enhancing the efficiency of water resource management, supply, and production. This primarily encompasses four key areas:

　　(1) To prevent water leakage, an intelligent water billing system has been established.

　　(2) To enable efficient allocation and utilization of water resources, alternative water trading and utilization systems have been established.

　　(3) To better advance the development of water resources information management, an advanced sensor network and a water resources management information platform system can be established.

　　(4) Integrate the smart water network with the power grid in an organic manner, thereby enhancing the operational efficiency of the water resource management system.

　　Dedicated to the development of smart water management, the company regards the “intelligent water system” as a key component of the “smart city.” Built on the company’s “control and information integration system,” this system manages operational data from various water treatment facilities, enabling improvements in the efficiency of water-cycle operations, accurate forecasting of water-use trends, and substantial enhancements in regional water-supply efficiency.

　　Centering on application-driven, demand-oriented approaches, water-sector informatization efforts are closely aligned with the integrated “environment–resources–safety” governance framework and the “four centers” initiative. Leveraging the smart-city network infrastructure, these initiatives fully capitalize on institutional reform advantages to promote online business workflows, coordinated collaboration between urban and district levels, and cross-sectoral consolidation and integration. The goal is to facilitate user-friendly application services, enable intelligent evaluation and decision-making, refine industry oversight, standardize administrative law enforcement, and support public social services, foundational industry management, and the transformation of government functions.

　　Yuanjie Water Services adheres to the principles of “unified management, unified construction, unified standards, and unified planning,” and, in line with the overarching objectives of delivering “efficient water services, people-centered water services, safe water services, and low-carbon water services,” it has adopted a coordinated approach to IT infrastructure development. Specifically, it is proactively advancing the construction of smart water systems by focusing on the establishment of a data-sharing platform, the development of a data center, and the enhancement of network infrastructure.

　　In the information age, smart water management represents both a new paradigm for the scientific governance of water resources and a new goal for the modernization of the water sector. By fostering multi-stakeholder engagement among government regulatory agencies, water service providers, and citizens, and by leveraging cutting-edge technologies, smart water management enables more automated water resource control, more proactive service delivery, more comprehensive sensing capabilities, more coordinated management, and more evidence-based decision-making.

　　The overall architecture of smart water management comprises five key components: the smart water support and assurance system, the smart water automated control system, the smart water proactive service system, the smart water multi-dimensional sensing system, and the smart water intelligent application system.

　　Smart Water Management Development Strategy

　　Shift mindsets. Smart water management is of paramount importance in the information age; to better integrate it into water management, we should fully leverage its advantages by enhancing scientific decision-making for water-related emergencies, improving emergency response capabilities for such incidents, and optimizing the organizational structure of water management agencies.

　　Service integration. Centered on the general public, smart water services leverage mobile devices and the internet to provide citizens with one-stop water-related services, including real-time water-quality complaints, online processing of administrative permits, electronic payment of water bills, and smart metering. These capabilities significantly enhance the quality of public water services.

　　Cross-sectoral collaboration. Smart water management goes beyond mere business coordination and resource sharing among industry departments; it entails the comprehensive integration of all relevant sectors. In the event of a water-related emergency, it is essential to bring together news media, agriculture, environmental protection, water resources, land and resources, forestry, meteorology, health, transportation, and other pertinent agencies to jointly provide decision support, facilitate operational coordination, enable information sharing, and manage all water-related aspects of emergency response. This approach ensures that the public receives warm, convenient, and timely services, while water service providers deliver more efficient and user-friendly solutions to stakeholders with interests in water-related matters. Moreover, when water-related disasters occur, accurate and prompt information must be disseminated to all sectors of society at the earliest possible moment, enabling swift implementation of remedial measures.

　　Public participation. Smart water management leverages cloud computing to enable platform sharing and data openness, thereby creating a win-win outcome for the general public, water service providers, and regulatory authorities. This model of public engagement can expand the supply of public services, reduce the corresponding financial investment by government agencies, and ensure that the public benefits from diversified, high-quality, and cost-effective services.

　　Implementation Approaches

　　Information technology and management models coexist. The mature application and rapid development of modern information technologies, such as cloud computing and the Internet of Things, have laid a solid technological foundation for the construction of smart water services, enhancing the effectiveness, flexibility, efficiency, and clarity of water resource management. This has truly enabled a flattened, multi-dimensional, highly efficient, agile, precise, and granular water management model.

　　Specialized research should be conducted in tandem with top-level design. The development of smart water management is inherently predicated on “unified work deployment,” “unified operating environment,” “unified business framework,” “unified technical architecture,” and “unified technical standards.” The appropriate approach is to undertake comprehensive top-level design that coordinates, consolidates, and integrates water-sector development in a top-down manner. At the same time, it is essential to actively carry out various specialized studies and develop detailed, in-depth plans.

　　Conclusion

　　The development of smart water management represents a new, science-based approach to water resource management and is an indispensable step in China’s transition from traditional to modern water management. It is imperative to adopt a holistic, long-term strategic vision to strengthen the advancement of smart water management.

Ultrapure Water Processes and Project Case Studies

Stainless Steel Pipe and Water Tank Welding

I. Construction Preparation 1. The welded stainless steel water tank is fabricated using high-quality SUS304 or 316L stainless steel plates and glass-fiber-reinforced plastic panels. Materials are cut according to the tank’s specifications, then undergo a series of processes including shearing, film application, pressing, shaping, alignment, and final inspection before being delivered as qualified products. 2. Prior to construction, it is essential to thoroughly study the construction drawings and relevant technical documentation. Water tank construction drawings must be cross-checked with structural and architectural drawings, the tank’s manufacturing process should be fully understood, and all applicable construction and acceptance standards must be reviewed and documented in a detailed construction plan. 3. Before starting work, ensure that power supply at the construction site is properly arranged. Electrical usage on-site should be coordinated with the contractor but must meet operational requirements. 4. The construction area must be kept orderly, with a dry and well-ventilated working environment. 5. The strip foundation for the water tank must comply with the design drawings and installation requirements, with a minimum height of 200 mm and an allowable deviation of no more than 5 mm across all foundations. 6. A dedicated site supervisor shall be assigned to oversee all aspects of the construction team’s activities and to conduct continuous quality control of the water tank throughout the entire project. Materials Preparation 1. Raw materials such as welding wire and electrodes must undergo rigorous quality inspections; their chemical composition, mechanical properties, and weldability must conform to national standards. 2. Stainless steel pressed plates must be carefully inspected upon arrival and prior to use to ensure they meet all relevant quality and technical requirements. 3. Channel steel base frames must also be thoroughly inspected upon arrival and prior to use to confirm compliance with applicable quality standards. 4. Stainless steel tension rods and vertical posts must be inspected upon arrival and prior to use to verify that they meet all relevant quality requirements. II. Major Equipment Preparation 1. Equipment: TIG welders, electric arc welders, angle grinders, argon cylinders, power distribution boxes, etc. 2. Tools: Adjustable wrenches, hand hammers, screwdrivers, pliers, cutting tools, welding tools, etc. 3. Measuring instruments: Spirit levels, steel tape measures, plumb bobs, calipers, protractors, string lines, etc. III. Installation Process Flow Pre-Welding Preparations (1) Production Drawings and Process Procedures Before welding begins, it is imperative to thoroughly familiarize oneself with the production drawings and process procedures for the welded structure. This step is crucial for ensuring smooth production of the welded product. Key aspects include: The structural configuration of the product, the types of materials used, and associated technical requirements; Dimensions of the welded areas, as well as the design of the weld joints and groove preparations; The specific welding methods employed, along with parameters such as welding current, voltage, speed, and sequence, plus control of preheating and interpass temperatures during the welding process; Post-weld heat treatment procedures, inspection methods for welded components, and quality requirements for the finished product. (2) Base Material Pre-treatment and Cutting 1) Base Material Pre-treatment Pre-treatment of metallic structural materials primarily involves straightening and surface treatment of steel prior to use. If steel is not handled in strict accordance with relevant operating procedures during lifting, transportation, and storage, various deformations may occur, such as overall bending, local buckling, or wave-like distortion, which render the material unsuitable for direct use in production and necessitate correction. Thin plate straightening is typically performed using multi-roll leveling machines, while coiled steel sheets can also be leveled using similar equipment. 2) Cutting Mechanical thermal cutting methods must be used for cutting, with each piece clearly labeled with product name, drawing number, specification, graphical symbols, and hole diameters. Only after passing inspection may the material be used. Manual scribing and template dimensions must adhere to standard tolerances, taking into account both welding shrinkage and machining allowances. When cutting and preparing stainless steel plates, special attention should be paid to hardening phenomena near the cut edges. 3) Groove Preparation To ensure that the weld bead thickness meets specified dimensions, avoids defects, and achieves full penetration, the edges of the weld joint must be prepared into various groove configurations based on plate thickness and welding process requirements. On-site Welding Procedures (1) Welding Sequence 1) Welding the Base Frame Based on the dimensions of the water tank modules, determine the spacing of the channel steel. First, tack weld the channel steel in place, then use a spirit level to check for flatness before proceeding with full welding. 2) Fixing the Bottom Plate Place the inspected and qualified water tank bottom plate onto the channel steel base frame (prior to placement, apply anti-rust paint to the channel steel to prevent corrosion between dissimilar metals). Note: Applying anti-rust paint to the surface of the channel steel serves to prevent metal rusting and enhance coating adhesion. After painting, the metal is effectively isolated from air contact, and the anti-rust paint induces metal passivation, inhibiting chemical or electrochemical reactions between other substances and the metal, thereby providing effective rust protection. Furthermore, since the anti-rust paint reacts with the metal surface to form a passivation layer, the bond between the paint and metal becomes not only physical but also chemically strong, resulting in exceptionally high adhesion. This effectively isolates the channel steel from direct contact with the stainless steel panel, ensuring that the water quality inside the tank meets standards. 3) Fixing the Side Panels Tack weld the inspected and qualified water tank pressed panels onto the bottom plate in sequence. After each panel is secured, use a spirit level and plumb bob to verify verticality; only when everything is confirmed correct should the next panel be tack welded, continuing until all side panels have been tack welded. 4) Fixing the Cover Plate Secure the inspected and qualified water tank cover plate onto the side panels, with vertical posts installed between the center of the cover plate and the tank bottom to ensure overall flatness. 5) Installing Accessories Fix the internal tension rods according to the tank’s structure and install both internal and external ladders. 6) Drilling Holes Drill holes at the positions indicated on the drawings and according to the required pipe diameters, then tack weld short flange pipes at each opening. The flanges must be aligned horizontally and vertically as specified. 7) Perform overall welding of the water tank, ensuring that the welds are free of porosity, slag inclusion, and other defects. (2) Welding Process 1) Welders must pass the appropriate qualification tests as stipulated by the “Welding Code” before being authorized to perform on-site welding. 2) It is strictly forbidden to arbitrarily strike an arc on the surface of the workpiece, test current, or use temporary welding supports. 3) The TIG torch and argon pressure regulator used by welders must be regularly inspected to ensure that the argon flow remains laminar during the TIG root pass. 4) Prior to joining, the groove surfaces and both inner and outer walls of the base material must be thoroughly cleaned of oil, paint, scale, and other contaminants until a metallic sheen is revealed. The cleaning range should extend 10–15 mm on each side, with a joint gap of 2.5–3.5 mm. 5) Joint gaps must be uniform and straight; forced fitting is prohibited, and misalignment should not exceed 10% of the wall thickness or 1 mm. 6) If local gaps at the joint are excessively large, they must be corrected; inserting any filler material into the gap is strictly forbidden. 7) Once the joint passes inspection, mark 4–5 points along the joint length for tack welding, using the same materials as for the final weld, with a tack weld length of 10–15 mm and a thickness of 3–4 mm. 8) After completing the root pass, carefully inspect the quality of the root weld and proceed with the TIG cap pass only if it is deemed satisfactory. 9) Arc initiation and termination must both occur within the joint; termination should completely fill the molten pool, guiding the arc back into the groove to extinguish it. 10) If defects arise during tack welding, TIG welding, or the cap pass, they must be ground away using abrasive tools before resuming welding; repeated melting to eliminate defects is strictly prohibited. 11) Pay close attention to the quality of the joint and the termination; ensure good fusion at the joint and complete filling of the molten pool during termination to guarantee weld tightness. 12) Immediately after completing the cap pass, clean up slag and spatter from the weld surface. Causes of Defects in TIG Welding and Preventive Measures Weld Defects Causes Preventive Measures Porosity Impure argon, ruptured gas hoses, moisture in the gas line, tungsten electrode contamination, or excessive metal fumes entering the molten pool. Replace with pure argon, inspect the gas line, grind or replace the tungsten electrode, and thoroughly clean the weld. Poor penetration with weld bumps Uneven welding speed, lack of skill. Strengthen basic training and maintain consistent welding speed. Severe blackening and oxidation of the weld Low argon flow, slow welding speed, high temperature, or excessive current. Increase argon flow, speed up welding, or appropriately reduce current. Shrinkage cavities Improper termination method, abrupt stoppage of the arc. Change the termination method and gradually slow down the welding speed to achieve a smooth finish. Cracks High or low welding temperature, poor penetration, or overheating. Ensure full penetration, adjust current and welding speed appropriately, and change the termination position. Incomplete penetration Fast welding speed, low current. Slow down the welding speed or increase the current. Poor fusion Misalignment, incorrect torch angle, or fast welding speed with low current. Correct misalignment errors, master proper torch angles, and appropriately slow down the welding speed while increasing the current. Burn-through Inexperienced technique, excessive current or slow welding speed. Reduce current or speed up welding, and strengthen basic training. Surface damage to the weld Inaccurate arc initiation, poor ground connection. Initiate the arc accurately, avoid striking the arc directly on the workpiece, and ensure proper grounding. Weld inclusion of tungsten Striking the arc with the tungsten electrode in direct contact with the workpiece. Maintain a certain distance between the tungsten electrode and the workpiece during arc initiation. Irregular weld bead formation Uneven gun travel speed, uneven wire feed speed. Ensure consistent welding speed and wire feed, and strengthen basic training. Undercut Incorrect torch angle, uneven molten pool temperature, improper wire feeding. Adjust the torch angle to achieve uniform molten pool temperature, and pay careful attention to the position, timing, and speed of wire feeding. Water Pressure Test for Sealing Performance After completing the welding, wipe all welded areas dry with a dry towel, then fill the tank to the marked capacity and let it sit for 24 hours. Afterward, wipe all welded areas again with a dry towel—there should be no trace of moisture on the towel.Water Tank Cleaning and Disinfection Prior to being put into service, potable water tanks must be thoroughly cleaned. During cleaning, workers must wear plastic shoe covers before entering the tank. First, use a cleaning agent to scrub away dirt and grime inside the tank, then flush the interior with tap water until the effluent is free of particulates and appears clear and transparent—only then is the tank considered compliant.

Stainless Steel Pipe and Water Tank Welding

Separation of Clear and Turbid Streams

The turbidity–clarification separator features an internal structure comprising a backwash water distributor, filter cotton balls, a stainless steel mesh, a flared inlet, baffles, and other components. A flocculant dosing unit delivers the flocculant and water through a pipeline mixer to the lower section of the separator, ensuring thorough mixing and reaction between the flocculant and water. This process causes fine suspended particles to aggregate into larger flocs. The flocculated water then passes through an intermediate baffle and is further filtered by high-efficiency filter cotton at the upper section, after which the clarified water enters the disc-membrane purifier. Meanwhile, the larger floc particles that have settled at the bottom are periodically removed via an automatic sludge-discharge system, effectively eliminating the aggregated contaminants. The first two stages address sand removal and turbidity reduction, ensuring that the effluent turbidity remains within the specified limits. The system also enables automated sludge discharge, continuous turbidity removal, and vigorous air–water backwashing of the filter cotton balls, thereby maintaining the upstream purification performance.
