RO drinking water filtration system at Nguyen Van Dinh Primary School

The source water is supplied to the first source tank. The machine sucks water from the upstream tank, pushes through 3 columns, multi-filter: Manganese sand, activated carbon, softener filter into the intermediate tank.

From the intermediate tank through the fine filter to the vertical pump, to the reverse osmosis RO, there are 2 water sources at RO, the pure water source and the discarded water source.

At the pure water tank, fill the tank with Ozone, the filling pump pushes through the UV lamp, disinfects 0.2 Micron to produce pure drinking water.

Waste water is discharged to the free drain, not reused for RO water purification.
