Overview

The MediumEDI series uses urban tap water as the water source, with an hourly water production rate of 45-90 liters. It is equipped with a new 5.0-inch touch screen control system and adopts standard two-stage reverse osmosis system technology (double pump double membrane+intermediate water tank) and EDI technology and modules. It can conveniently and quickly produce Grade III pure water with a stable conductivity of 1-5 μ s/cm, 10M Ω. cm (25 ℃) or above, and TOC amp; amp; 30ppb * grade II pure water and 18.2M Ω· cm (25 ℃) ultrapure water!

Product Details

Product Introduction

The system uses urban tap water as its water source, equipped with a brand new 5.0-inch touch screen control system, optimized standard two-stage reverse osmosis process, and adopts dual pumps, dual membranes, and transition water tanks, resulting in lower energy consumption, less wastewater, and more stable water quality. Even under conditions of poor source water quality, the conductivity of the secondary RO produced water can remain stable at 1-5 μ s/cm.

*Our EDI technology and modules provide you with consistent grade II pure water with TOC<30ppb at 10M Ω· cm (25 ℃) and above, as well as 18.2 M Ω· cm (25 ℃) ultra pure water at optimized operating costs, in compliance with the water quality standards set by GB/T 6682-2008, GB/T33087-2016, ASTM, CAP, CLSI, EP, and USP.
