CEDI MODULE FOR SEAWATER & BRACKISH WATER DESALINATION
Desalination of seawater and brackish water | coastal, island and inland plants
This DUBHE CEDI module is built for desalination of seawater and brackish water, where a reverse osmosis train alone cannot reach the low conductivity demanded by high purity applications. Used as a polishing stage after seawater RO or brackish water RO, the module removes residual sodium, chloride, boron and silica to deliver high pure water for industrial, municipal and remote-site supply.
The 90-95% recovery rate and wide pH chemical cleaning tolerance make the module suitable for plants operating with variable feed salinity, and the compact stack design keeps the desalination skid footprint small for island, coastal and inland brackish water installations.
(General industrial desalted water, high purity water)
