Our Double pass RO system is the system that adopt double RO for processing water with capacity 100L/H to 100m3/H.

Output water from first stage RO as feed water of the second stage RO, The second stage RO is used to remove ion further more such as Ga2+, Mg2+, Fe-2, SO4-2, Cl-1, Na+, to make sure finish output water further pure, conductivity ≤ 0.5μ S

The double pass RO system has below advantage

Running persistently, output water quality is very stable.
Does not need acid and alkali to regenerate.
Does not need stop system to make regeneration
Save back wash and cleaning water
High recovery rate(95%)
No sewage discharge
Compact in structure, installation space saving
Does not acid and alkali, avoid operator injured, it is very safe.
Low maintenance cost
Low installation cost

Double pass RO system widely used in

1. Pharmaceutical industrial: Produce super pure water for prescription, Reagent, washing, injection and concentration of the medicine.
2. Electric power industry: Boiler water replenishment produced
3. Electronics industry: Producing super pure water for Semiconductor usage, Molectron washing.
4. Food industrial: Produce preparation water, production water, concentration of Tee, vegetable juice and other thermal sensitivity vegetables.
5. Drinking water plant line: Produce drinking water.
6. Petroleum Chemical Industry: Oil field feed water
7. Sea water desalination: Used on regasification vessel for producing potable water.
