250L/H Car Urea Liquid EDI Ultra-pure Water Plant | Electrodeionization System

1. Equipment Introduction.

EDI ultrapure water is the upgraded version of the new ultra-pure water equipment in the 20th century, raw water is through the reverse osmosis system to produce pure water, through the EDI device’s clever combination of electrodialysis and ion exchange technology, this process no longer requires the traditional acid and alkali chemical regeneration and can continuously produce ultrapure water.

EDI system

NEWater has been improving the whole set of RO and EDI systems for 20 years, using imported reverse osmosis membrane elements and EDI membrane stack devices to stabilize the water quality and flow, the system adopts fully automatic Siemens and Mitsubishi PLC control, the equipment has the advantages of advanced process flow, stable water quality, fast operation, low cost, environmental protection can be recycled, etc.

All of our products have passed the international CE certification. Customized solutions are designed for different fields of use and can be installed and commissioned at home.

3.  Equipment Control and Performance.
Reverse osmosis pure water system has two core components configuration.

The reverse osmosis membrane is the core component to achieve reverse osmosis, is a simulated biological semi-permeable membrane made with certain characteristics of the artificial semi-permeable membrane.
NEWater choose industry-recognized high-standard RO reverse osmosis – imported Dupont Dow membrane, water quality stability, long service life. You can also optional domestic high-cost RO membrane.

RO System Advantages

  • Implementation of automatic control, and automatic flushing of RO membrane to reduce the rate of contamination.
  • Automatic shutdown for no water and low pressure or full water, automatic water production for water tank shortage.
  • Low-pressure switches protect the high-pressure pump to avoid damage to the pump group.
  • Produced water conductivity meter continuously monitors produced water quality.
  • Grouped inlet and discharge pressure gauges to continuously monitor the differential pressure of the reverse osmosis membrane and indicate when cleaning is required.
  • Automatic water stop valve to avoid water precipitation caused by the continued inflow of water during the shutdown.
  • Stable reverse osmosis host system with automatic operation, group protection, and real-time monitoring.

EDI technology advantages.

  • Ability to continuously produce produced water quality that meets user requirements.
  • Modular production, which can be controlled automatically.
