EDI system water treatment system
EDI water system Technical parameter:
Inlet water conductivity: 1-20us/cm
PH: 5-9
TOC (total organic carbon) : below 0.5mg/L
Inlet water pressure: ≤0.7MPa
Water temperature: 5-40°C
Outlet water quality: ≥15MΩ.cm(25°C)
Recovery rate: 90-95%
Constructure of the EDI water system:
EDI moduleOn line monitering instrument of resistance meter conductivity meter Power control system: the main electrical components are from Schneider, Omron and domestic high-quality devices, PLC control, electric ball valves and etc.How it works
Usually the EDI feed water is from the two-stage reverse osmosis (RO) water. The resistance of RO treated water is generally 40-2μS/cm (25 ° C). EDI water resistivity can be as high as 18 MΩ.cm (25 ° C).
According to the different purposes of deionized water and various system configuration settings, EDI system is suitable for preparation of ultra-pure water with the resistivity between 1 ~ 18.2MΩ.cm (25 ° C) .
EDI water system Advantage
Module design, outlet water of each module have a definite value, biggest single machine output can reach 300 m³/h after combination.
Simple and full-automatic unmanned operation.
Small area occupy, low operating cost.
No need of acid and alkali, no wastewater discharge, meet environmental protection criterion.
EDI water system Applications
Field of power, electronics, pharmaceuticals, chemical, food and lab, etc.
EDI
Note:
Water flows to EDI machine must be the water from RO pure water machine or the same good quality water.
