Ro edi water treatment system for pharmaceutical and chemical is the eighties developed a membrane separation technology, which mainly use the semipermeable membrane permeation principle, to give it a certain way by applying a pressure on the natural infiltration direction against the force of the water in the concentrated solution dilute the solution to penetrate this way is called reverse osmosis. By the components of the device is reverse osmosis reverse osmosis unit.

Two pass reverse osmosis + EDI preparation (purified water process characteristics)

1 Suitable for raw water salinity compared Height regions;
2 product water conductivity is better;
3 one-time investment of less;
4 lower operating costs;
5.Stability.

• Multimedia filter: Remove suspended solids, sediments and impurities.
• Activated carbon filter?Residual chlorine adsorption water.
• Water softener: Remove the calcium and magnesium ions in water, reduce the hardness of water
• Security filter: Prevent particles from entering the RO membrane.
• High pressure pump: Provide high pressure to drive the seawater pass the RO membrane.
• RO system: Removing 98% TDS from the feed water.
• CIP system: To clean RO membrane.
• EDI lift pump: Provides steady pressure for EDI
• EDI system: The reverse osmosis water production is further purified, and the resistance value of the anti-osmosis can be reached to about 15 megaohm.

1. Feeding water: RO pure water, the electrical conductivity of the general water is 4-30us/cm.
2. PH: 5.0-8.0 (under this PH condition, the water hardness is not too high)
3. Temperature: 5-35?
4. Feeding water pressure: maximum is 4kg/cm2 (60psi), minimum is 1.5kg/cm2 (25psi).
