Objective
The purpose of this project is to demonstrate a new membrane separation technology to produce 600 000 m3/year demineralised water from canal water (canal de la Deûle). The membrane treatment includes seven physical steps. No chemical is used for the reverse osmosis treatment, except for the membranes cleaning and protection operations.
This project is part of a general policy in CERESTAR to reduce water consumption. The main objectives are :
- to decrease by 35 % at least the city water consumption in the Haubourdin plant, by using water of a lower grade quality.
- to substitute the classical demineralised water production process with a more environment-friendly technology: the reverse osmosis process eliminates the discharge of 2300 kg/day salt (sodium chloride) in the canal.
The CERESTAR company is a subsidiary company of ERIDANIA-Beghin Say. It manages an important corn starch factory in Haubourdin (Nord). This industry needs quantities of demineralised water in the different stages of the process.
For 30 years, the Haubourdin plant has been using about 2 000 000 m3/year city water for its industrial applications : water for steam boilers and process water. The city water is either softened or demineralised through classical ion exchange resins process.
