Core Values

　　Core Values

　　Govern water management for the people’s wellbeing and deliver value to society; foster innovative thinking, uphold integrity and earn trust, surpass ourselves, and pursue excellence.

　　I. Innovative Thinking

　　Thinking is the “system” that carries knowledge; only by continuously updating your thinking patterns can you truly leverage knowledge to upgrade your capabilities.

　　1. Radiative Thinking

　　Radiative thinking, commonly known as divergent thinking, involves branching out from the characteristics, context, or related clues of a given subject to broaden one’s understanding and expand one’s perspective. This way of thinking not only helps you quickly grasp unfamiliar concepts and swiftly reach a solid 80-point foundation in a new field, but also enables you to handle challenges with composure and ease—allowing you to both advance boldly when opportunities arise and retreat strategically when necessary.

　　2. Think from Multiple Perspectives

　　Multi-perspective thinking involves examining issues from multiple angles to achieve overall optimization, transcending the constraints of isolated points, linear relationships, and static surfaces. It encourages holistic, three-dimensional reasoning, allowing one to approach problems either through a single mode of thought or by integrating diverse perspectives.

　　3. Substitution Thinking

　　The mindset of substitution involves breaking down a problem into its constituent elements and rearranging or transforming those elements to open up new avenues of thought. Simply put, in mathematics we have all learned to use the method of substitution to solve quadratic equations in one variable: by decomposing a complex expression into simpler parts and systematically replacing variables, we can ultimately arrive at a solution.

　　Thinking in terms of substitution is, in essence, empathy and perspective-taking—it helps you identify the fundamental purpose of your work, prioritize tasks based on their importance, and ultimately boost your productivity.

　　4. Shift in Thinking

　　Shift-thinking involves seeking alternative approaches to problem-solving when conventional logic fails. Reverse thinking, which we often discuss, is a form of shift-thinking that entails stepping outside established logical frameworks and considering issues from the opposite perspective. Shift-thinking is inherently disruptive; it requires transcending existing knowledge systems and drawing on insights from multiple disciplines and fields to address complex problems.

　　5. Origin Thinking

　　“Thinking from the starting point,” as the name suggests, means returning to the origin in one’s reasoning. I personally understand it in two ways: first, seeking answers by tracing the trajectory of development and applying universal logic; second, establishing a foundational starting point for a given matter and continuously comparing, reflecting upon, and correcting deviations as it evolves and is built.

　　6. Opposing Thinking

　　Contrarian thinking involves considering the opposite of a given situation, exploring alternative possibilities, or raising questions and doubts, thereby approaching problems in a critical manner. In everyday work, it is crucial to have one’s own convictions and stance, as this forms the foundation of a distinctive personal style. To cultivate such a mindset, we must develop a habit of contrarian and critical thinking: we should not uncritically accept others’ views and interpretations, but instead independently analyze and internalize them, articulate our own well-reasoned perspectives, and clearly explain the rationale and insights behind them.

　　7. Collaborative Thinking

　　Associative thinking goes beyond the mere presentation of a single entity; it involves making connections and drawing inferences that move from phenomenon to essence, from surface to core, and from positive to negative.

　　Associative thinking is the most frequently used technique when we create mind maps, as it involves making connections, conducting analysis, and extending ideas to deepen our understanding and guide our next steps.

　　II. Defending the City and Gaining Trust

　　A single person guards the city—yet in truth, what is being guarded is the heart: a heart filled with confidence and trust. Integrity is a traditional virtue of the Chinese nation and a fundamental moral standard highly esteemed by Confucianism. As a concise term for honesty and trustworthiness, integrity refers to an earnest, sincere, and truthful attitude in one’s conduct and dealings—upholding one’s word and honoring promises. Sincerity is the inner disposition that underpins integrity, while integrity is the outward manifestation of sincerity. Today, this principle has far-reaching implications for our efforts to build a socialist harmonious society, accelerate socialist modernization, deepen education in integrity and moral values, and strengthen personal moral cultivation. The concepts of “xin” (trust) and “cheng” (sincerity) first appear in the Book of Documents, where “xin” is understood primarily as the ability to keep one’s word and honor commitments—“to be trustworthy is to act in accordance with righteousness; one’s words can be relied upon.” When “xin” is combined with “cheng” and with goodness, it is believed that through “cultivating one’s sincerity” one can attain “supreme sincerity,” ultimately winning the trust of others and pleasing one’s family. Thus, trust itself embodies moral goodness: “a good person is one who is trustworthy.”

　　III. Surpassing Ourselves

　　The greatest enemy in life is oneself. Therefore, the only true path to self-fulfillment and destiny lies in one’s own transcendence; all other pursuits are but detours, unworthy of the highest esteem. To transcend is to know oneself, to dare to challenge oneself, to conquer oneself, to go beyond oneself—and, by surpassing others, to stride toward success. It is a dynamic process, a verb in action. Each of us is capable of transcending ourselves. And when we keep on transcending, day after day, a bright tomorrow filled with hope and a dazzling rainbow will await us, embracing and nurturing us.

　　IV. Pursuing Excellence

　　Pursuing excellence has two dimensions: first, striving for outstanding performance; second, striving for exceptional social value. It means moving forward with the times, constantly pressing ahead, and never standing still. It is a new idiom that embodies a scientific, dynamic, and ever-changing worldview—one that views the world through the lens of development and respects the inherent laws of change—so that together we can create a beautiful and glorious future.

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.

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.
