  Details:

Medium EDI-S uses urban tap water as its water source. The system produces 45-90 liters of water per hour. It is equipped with a new 5.0-inch touch screen control system, and adopts standard two-stage reverse osmosis system technology (double pumps, double membranes + intermediate water tank) and EDI technology And modules, which can conveniently and quickly continuously produce grade III pure water with a conductivity of 1-5μs/cm, grade II pure water with a conductivity of more than 10MΩ.cm (25°C) and TOC<30ppb*, and 18.2MΩ.cm(25 ℃) ultrapure water, the effluent water quality fully meets the level I water quality standards established by GB/T 6682-2008, GB/T33087-2016, ASTM, CAP, CLSI, EP and USP.
Optimized standard two-stage reverse osmosis process, using double pumps, double membranes and transitional water tanks, so that the system has lower energy consumption, less waste water, and more stable water quality. Even in the working conditions of poor source water quality, the conductivity of the secondary RO product water can also be stabilized at 1-5μs/cm.
Advanced EDI technology and modules provide you with consistent 10MΩ.cm (25°C) or more, TOC<30ppb grade II pure water and 18.2MΩ.cm (25°C) ultrapure water at an optimized operating cost. It complies with the Grade I water quality standards established by GB/T 6682-2008, GB/T33087-2016, ASTM, CAP, CLSI, EP and USP.

Comprehensive consumable management function, PP, KDF, AC, RO, DI, UP, UV, UF, TF consumable life can be set, display the used time and amount, and automatically remind replacement when expired

System alarm function, automatic detection and alarm functions such as water shortage alarm, water tank full alarm, source water, RO reverse osmosis water, DI deionized water/UP ultrapure water, water quality exceeding alarm, etc., to provide safety assurance

Fully automatic RO membrane anti-scaling flushing (the interval and duration of flushing can be set) and manual forced flushing procedures to extend the service life of RO membranes

Factory and customer secondary passwords, system settings are protected by passwords to prevent unauthorized changes

System time setting function, can set year/month/day/hour/minute, and timer standby (0~60Min) and timer shutdown (0~24Hour)

Complete information query and data management functions, water intake records-water quality and quantity, consumption of consumables and replacement records, instant alarms, historical alarms and other information

RO water unqualified discharge function, the patented RO water unqualified discharge device, realizes that the RO water entering the subsequent purification unit always maintains good water quality, effectively extending the service life of the subsequent purification column

Stainless steel spray-plastic chassis, ergonomic design, to prevent corrosion and rust, to ensure that the body is clean, in line with GLP specifications

Floor-standing design, with movable and fixed feet at the bottom, making installation and movement more convenient

Modular design, pretreatment, RO and subsequent purification units are all independent structures, system maintenance and filter replacement are more convenient

Pipes and joints are certified by NSF to minimize the TOC precipitation of the system and ensure the quality of pure water

DOW imported RO membrane membrane module, which realizes the combination of long life, stability and high salt rejection rate of RO membrane

Dual-wavelength (185nm&254nm) UV ultraviolet lamp assembly (imported tube), effective sterilization, reducing TOC, and enhancing the scope of application of the system

MWCO5000DUF ultrafiltration module (imported with original packaging), effectively removes pyrogen (endotoxin), and can be used for precise cell culture and IVF

Standard configuration of 0.2μm imported PES polyethersulfone composite filter membrane terminal sterilization filter to ensure the sterility of the terminal effluent
