This equipment is fit for drinking water production featuring appropriate structure and simple operation. After RO the water can meet the national standards of quality drinkable pure water. It is ideal equipment for water treatment.
Features
To ensure the water entry meet the requirements kinds of filters such as purifier, silica sand filter and sodium icon exchanger can be used for pretreatment.
The multi-grade pump is reliable, stable and of big brand; the membrane is most advanced one as TFC RO membranes, which can remove 99% of ions out of water.
With a conductivity instrument at the exit, User can easily monitor the quality of treated water.

Requirements for water entry
For safe and efficient working of RO system and long life cycle of membranes in RO, the water of entry needs to be pre-treated to meet the requirements as follows:
