Polished Mixed Bed Ion Exchange Ultrapure Water Equipment
Conductivity 0.055μS/cm Resistivity 18.2 MΩ·cm
1. Product Description of Polished Mixed Bed Ion Exchange
Polished mixed bed, also known as disposable mixed bed, is generally used at the end of the process to further improve the water quality. The resin of the polished mixed bed cannot be regenerated and reused. The so-called polishing means the surface treatment of the resin.
Polishing Resin: It is often said that polishing resins are generally used at the end of ultrapure water treatment systems to ensure that the effluent quality of the system maintains water standards. Generally, the effluent water quality can reach more than 18 megohms, and it has certain control ability for TOC and SIO2. The ionic form of the polishing resin is H and OH type, and it can be used after filling and can be used without regeneration. Generally used in the semiconductor industry.
2. Product Details of Polished Mixed Bed Ion Exchange
Polished mixed bed general design flow rate: 40-60m / h
Pipes of what materials are generally used in pure water system piping: PVC is used before the entrance of the polishing mixed bed, and PVDF is used after the export. In addition, the polishing mixed bed should be installed as close as possible to the use end, because: 1. The polishing mixed bed basically does not require maintenance management, and installation on the site and installation on the factory side will not affect the management. 2. Great benefits for improving water quality. 3. Maximum PVDF cost savings.
In order to obtain theoretical pure water with conductivity of 0.055μS/cm (resistivity 18.2 MΩ·cm) for electronics, medicine or other industries, after ordinary mixed bed or EDI water purification equipment, polishing mixed bed is usually installed for final fine deal with. The resin for polishing mixed bed is a mixture of anion resin and a cation resin which are relatively close in density. Since the resin of the resin cannot be separated from the anode and the cation resin, and they cannot be regenerated separately by acid and alkali, the polishing resin is ineffective. Do not use it.
3. Working Process of Polished Mixed Bed Ion Exchange
The process of reverse osmosis + EDI desalination water treatment system is as follows:
|Raw water tank → raw water pump → dosing device → quartz sand filter → dosing device → activated carbon filter → automatic softener → security filter → first-stage high-pressure pump → first-stage reverse osmosis system → intermediate water tank → two-stage high pressure Pump → two-stage reverse osmosis system → pure water tank → pure water pump → TOC decomposer → degassing membrane → precision filter → EDI unit → pure water tank → pure water pump → polishing mixed bed → membrane filter → water point of production line.|
