Frequently Asked Questions
What is a stainless steel clean water tank used for?
The stainless steel clean water tank is an essential terminal water storage and buffer equipment in water treatment systems. It stores purified water after filtration and purification, stabilizes system water pressure and flow fluctuation, and ensures continuous and stable water supply for downstream RO systems, production lines and domestic water equipment. It is specially designed for clean water storage to avoid secondary pollution.
What is the working principle of the clean water tank?
The purified water from pretreatment and membrane systems flows into the clean water tank for sealed storage. The tank balances the water inflow and outflow difference of the whole water treatment system, eliminates pipeline pressure fluctuation, and provides stable water head pressure for subsequent water supply. Equipped with breathing valve and sterilization accessories, it keeps the internal water environment clean and sterile.
What materials are used for the water tank?
Food-grade stainless steel materials are adopted, mainly SS304 and SS316L. SS304 is cost-effective and widely used for industrial pure water and general drinking water storage. SS316L has stronger corrosion resistance, suitable for ultra-pure water, pharmaceutical, food and beverage and high-standard sanitary water scenarios.
What are the standard structural features?
The tank adopts integral argon arc welding forming with seamless and smooth inner wall, no water residue and no dirt accumulation. Standard accessories include breathing valve, manhole, water inlet/outlet, overflow port, drain port and liquid level gauge. Full sealed design effectively prevents dust, bacteria and foreign matter from entering the tank.
Does the clean water tank support customization?
Yes, full-size customization is available. Customizable parameters include tank volume (0.5m³–100m³), diameter and height ratio, interface size and position. Special requirements such as internal mirror polishing, external matte treatment, anti-foaming device and online sterilization device can also be customized.
What are the advantages of stainless steel tank compared with FRP and carbon steel tank?
Stainless steel clean water tank features sanitary grade, no rust, no water quality secondary pollution, long service life and easy cleaning. FRP tanks are easy to age and peel off residues; carbon steel tanks are prone to rust and corrosion. Therefore, stainless steel tanks are the standard choice for purified water and clean water storage.
How to clean and maintain the water tank?
The smooth inner wall is not easy to scale and adhere dirt, reducing daily maintenance frequency. Regular manual cleaning and disinfection every 3–6 months is recommended. No special maintenance is required for daily operation. Check the liquid level gauge, breathing valve and pipeline joints regularly to ensure no leakage and smooth ventilation.
What is the service life of the stainless steel clean water tank?
Under normal installation and regular maintenance, the service life of SS304 tank can reach 15–20 years, and SS316L tank can serve more than 20 years. It has excellent weather resistance and can be used stably both indoors and outdoors
What working environment is it suitable for?
It is widely applicable for pure water systems, ultra-pure water projects, drinking water projects, industrial production water, boiler water supply and pharmaceutical & food processing water. It supports indoor and outdoor installation, adapting to various industrial and civil water treatment scenarios.
Is the tank pressure-bearing or atmospheric type?
Standard clean water tanks are atmospheric pressure type with open breathing valve to balance internal and external pressure. Custom low-pressure sealed tanks are available for special process requirements, which can match pressurized water supply systems.
