What is food grade flexible watertank and tankliner fabric?

What is flexible watertank and tankliner fabric?

There are 2type of fabric, for water tanks,

Portable water tank/non portable water tank, and water tank liner by steel frame for above ground water tank.

The portable and non-portable water tanks are mainly with enclosed design, it can be inflatable with air and water tight with valves for inlet and outlet, capacity from 200litres to 100000liters,

Designed for the weather, it is resistant to UV rays and withstands temperatures between -30ºC to 70ºC.

The water tank liner fabric is a fabric that to prevent the water in contact with steel and outside, to remain the water cleans, and no microbe comes through the wall of water tank, the fabric itself can be food grade level to USA FDA or Australia and New Zealand AS/NZS 4020-2018, It’s a fabric approved by this regulations for safety use.

1, Potable and Non Potable flexible water bladder tanks (Pillow Tanks) are inflatable , flexible, strong, light weight and a cost-effective answer to instant water storage and transportation requirements, Bladder tanks can be unrolled and installed fast and efficiently.

Flexible water tanks are a solution for the permanent or temporary storage of raw water. The water tanks can be found to store sanitary water at public works sites for living areas and construction works or at water treatment plants.

Applications include a wide range of industries such as farming, mining, manufacturing, marine and aviation.,fish farming, water storage, oil storage etc.
