Treatment steps in a nutshell The advanced purification removes all salts and other substances from the water, leaving ultra pure water as the end product.
Step 1 Ultrafiltration The ultrafiltration system removes even the smallest undissolved compounds from the WWTP effluent. No chemicals are required for this.
Stap 2 BODAC, een speciale actieve kool techniek Bio-foiling of osmosis membranes is a persistent problem. NWTR solved it with a biologically active carbon filter. Without chemicals.
Step 3 Reverse osmosis (RO) With the first reverse osmosis, 98% of all dissolved salts (minerals) are removed.
Step 4 Electro-deionisation (EDI) The last step, a combination of RO and EDI, removes the last dissolved minerals (ions).
