RO+EDI+mixed  bed  series  ultra-pure  water  machine

Description:

RO + EDI + mixed bed is generally the source of water is tap water quartz sand filtration, activated carbon filters, softeners, security filters, booster pumps, reverse osmosis systems and EDI systems, UV disinfection systems plus precision filter and so on.

Some customers believe in this single-stage reverse osmosis water is not allowed to enter the EDI system, which is not considered to be entirely correct. Because it depends on the water quality entering the RO system and RO system to comprehensive judgments, and before entering the RO system as long as the hardness is reduced, as well as to ensure the reliability of the pretreatment case, then there is a relatively good performance of reverse osmosis the case of the film, the water is completely into the EDI system. But if you can not guarantee, then it is not directly into the EDI system. Because it will reduce its life.

Single-stage reverse osmosis water quality EDI configuration can be done over 10 megohms. If you want to achieve ultra-pure water, it also is equipped with precision mixed bed. The device structure is equipped with mixed bed anion and cation exchange resin, carbon steel lining equipment. After the RO water produced by the middle of the pump pressure from the upper into the mixed bed ion exchange resin flows through a variety of ions and ion exchange water resin ion exchanged into pure water. Mixed bed after working for some time, water production increased conductivity, the output of the water does not meet the requirements, they need the use of renewable means resin regeneration, active recovery exchange resin.

To prevent the RO membrane element in the choice of using desalinated water, while its concentrated dissolved solids in the water side fouling RO membrane surface, affect the performance of RO membrane, and thus before the reverse osmosis unit to set a scale inhibitor means plus scale agent metering device consists of tank and metering pump.

Plus inhibitors main role is through the initial raw water purification, reverse osmosis host water reached the requirements to ensure long-term stable operation of reverse osmosis host.

Now reverse osmosis membranes for water purification material mainly cellulose acetate and aromatic polyamides. These semi-permeable membrane material to do film uniformity, high filtering effect. Reverse osmosis technology is the main way to get pure water, reverse osmosis technology has low cost, high efficiency, easy operation and easy maintenance.

Feature:

• no acid regeneration: in mixed bed resin acid regeneration need to use chemicals, and EDI processing and eliminates the heavy work of these hazardous substances, protection of the environment. 
• continuous, simple operation: due to changes in the mixed bed regeneration and water quality each time, so that the operation becomes complicated, and the process EDI product water is stable and continuous, product water quality is constant, no complicated operating procedures, the operation is greatly simplified.
•  reduces installation requirements: EDI system compared with the considerable volume of treated water mixed bed, there is less volume, which uses modular structure, it can be flexibly configured according to the height and cellar space. The modular design makes EDI work in the production of easy maintenance.
