School Laboratory Ultra-pure Distilled Water Equipment Deionized Water Machine

ZYC External water tanks is optional to meet different need and assure ample water-supply.
Whole plastic shell with high-strength, avoid rusting and keep clean, to meet GLP standard.
2 door and easy-to-replacing cartridge design, convenient to maintain system and replace cartridges.
Tube and adapter with NSF authorization and top quality, reduce TOC level and assure ultrapure waterA's quality.
Optimized pretreatment (including PP fiber, KDF and active carbon cartridge), effectively protect RO membrane.
RO module with DOWA's membrane, ensure long life, stable operation and high desalinization rate.
DOWA's top polishing resin, ensure ultrapure waterA's quality up to 18.2 MIC.cm, with the lowest TOC level.
Double wavelength (185&254nm) ultraviolet lamp module, restrain bacteriaA's increase and reduce TOC.

The process flow
The technology process is divided into source water pretreatment system,reverse osmosis system and ultra-pure system.
1. Source water pretreatment system: PP fiber filter + AC filter + Softener
2. Reverse osmosis system: It has high removal rate more than 99% for high valent ions, colloids, bacteria and organic matter
(including endotoxin) with molecular weight greater than 300Dalton.
3. Ultra pure system: Ion exchange resin using H + exchange cation out the water in the filter ,using OH- exchange anions out the
water , the replaced H + and OH- combined to produce H2O, ultra-purified column filling the United States Dow UPW-450 Ultra-pure
water for nuclear grade resin, the water resistance of up to 18.25 MIC.cm.
