Reverse osmosis water purification system can do for waste water purification

Brand Name DRAWELL
Place of Origin Shanghai, China
Model Number RO DI digital plus

Product Features

Smart series water purification syste

Features and functions:

n   One time injection molding process case, material: Polypropylene PP.

n   Elegant and compact case, integrating pre-filter, RO, DI, UV, UF and terminal filter into one.

n   All filters are built-in, the smallest outside space.

n   Top cap of pre-filters in the case can be rapidly opened to replace the pre-filters without opening the case.

n   With electronic pressure sensor and microcomputer controlling, the system automatically produces pure water.

n   RO membrane auto flushing,

n   Automatic stop without water, automatic stop when water tank full, automatic cutting off water when pump stopping, guaranteeing 24 hours’ work.

n   On-line resistivity monitor, with apheliotropic LCD display, monitor deionized water or ultrapure water’s qualityreal-timely.

n   Attached portable TDS (total dissolved solid, ppm) test pen, with dry cell design, to monitor tap water and RO water’s quality.

n   Pipeline with NSF authorization to assure high quality ultrapure water.

n   New easy-inserting adaptor to make convenience of cartridge maintaining and replacing.

n   Different tanks to meet every needs and assure ample water-supply.

n   RO membrane, manufactured by DOW or CSM, to assure RO membrane’s long time and high quality of pure water.

n   4 ultrapure polishing resin cartridge with DOW’s polishing resin, to assure the top-level water quality of ultrapure water.

n   Double wavelength(185&254 nm)UV lamp cartridge, to achieve effective sterilization and reduce TOC index.

n   5000 Doulton ultra-filtration cartridge, Manufactured in Germany, to eliminate endotoxin. Suitable for Cell cultivating and IVF.

n   (0.45+0.1)µm PES terminal filter, to assure the quality absolutely axenic.
