1500L Two Stage RO Water System EDI System in Pharmaceutical Industry

Description of RO & EDI

RO(Reverse Osmosis), the basic working principle is : using of a special high pressure pump, increasing pressure to raw water, then force raw water penetrating through reverse osmosis membrane under the pressure. Only water molecules and solvent less than microns can pass through the RO membrane.

EDI (Electrodeionization) is a revolutionary water treatment technology ,it is a membrane separation desalination technology that skillfully combined the electrodialysis technology and ion exchange technology together ,which is high-tech , green and environmental protection technology. EDI plant has very high requests to raw water, usually we use double stage RO system production water as its raw water.

Working Process of Pharmacentical Water Purification System

raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → first-stage reverse osmosis → PH adjustment → intermediate water tank → second-stage reverse osmosis (reverse osmosis membrane surface with positive charge )→Purification water tank→Pure water pump→UV sterilizer→Ozone generator→Microporous filter→Water point

EDI Ultra Pure Water Pharmaceutical Water Purification System

EDI equipment is applied after the reverse osmosis system to replace the traditional mixed bed ion exchange technology (MB-DI) to produce stable ultrapure water. Compared with mixed ion exchange technology, EDI technology has the following advantages:
1. Stable water quality
2. Easy to realize fully automatic control
3. No shutdown due to regeneration
4. No need for chemical regeneration
5. Low operating cost
6. Small plant area
7. No sewage discharge

How Do Pharmaceutical Companies Choose Pure Water Equipment?

1. Pharmaceutical companies use a combination of ion exchange, reverse osmosis and ion exchange to obtain pure water, and then use distilled water to prepare water for injection. In the above-mentioned pharmaceutical water production process, ion exchange technology is still widely used as a means of deep desalination. However, when the ion exchange resin is regenerated, a large amount of waste acid and waste alkali will be produced, which will seriously pollute the environment and limit its development.
2. The removal rate of bacteria, pyrogens, viruses and organic matter in water by reverse osmosis membrane is 100%. Secondary reverse osmosis eliminates the use of ion exchange resins.

Pure water for medical use is stricter and more demanding.
1. It is often required that the resistance of ultrapure water should be higher than 15M. In order to ensure the safety of medical ultrapure water, the entire ultrapure water treatment equipment system is also composed of all stainless steel materials, and a sterilization device must be equipped before the water outlet.
2. Starting from the characteristics of ultra-pure water in the entire pharmaceutical industry, our company uses different technologies such as reverse osmosis and EDI to design different high-purity water treatment processes to meet the different requirements of high-purity water for different users.
