Reverse Osmosis Pre-Treatment Tanks High-Pressure Resistant for Industrial Water Treatment

Reverse osmosis pre-treatment tanks are constructed with high-quality composite HDPE liners, crafted using blow molding technology to deliver a continuous, seamless inner shell. The epoxy resin system and fiberglass filament-wound outer shell reinforce the liner, providing exceptional strength for high-pressure applications—critical for reliable performance in water treatment processes.

Operating at a maximum temperature of 49℃, these tanks undergo rigorous testing: 250,000 pressure cycle tests from 10psi to 150psi, ensuring durability under fluctuating pressure conditions. They are available in a range of colors—natural, blue, gray, black, green, yellow, red—with custom colors offered on request, adapting to diverse industrial aesthetics.

Their applications are versatile: ideal for multi-layer media industrial water treatment, water softening, sand-water filtration, and activated carbon filtration. This flexibility makes them a staple in sectors requiring precise water purification.

A notable industrial application is a chemical plant that integrated reverse osmosis pre-treatment tanks (size 3696 inches, φ900×2400mm, top&bottom 6" flange openings) into its water treatment system. Operating at 13.2～16.2 T/H, the tanks pre-treated water with sand and activated carbon, removing impurities before reverse osmosis. Over a year, the system maintained stable flow rates, with the tanks’ seamless design preventing leaks and reducing maintenance by 30% compared to traditional steel tanks.
