NWTR\u2019s pure water plant uses the effluent of the Emmen WWTP as a raw material. The water is treated in four steps. <\/p>\n\n\n\n

\"Treatment<\/figure>\n\n\n\n
  1. The pre-treatment phase consists of ultrafiltration (UF), which involves a series of membranes that retain all particles in the water, thus making the water completely clear and removing all non-dissolved substances.<\/li>
  2. BODAC filters. These biological filters remove all the nutrients from the water, preventing the accumulation of biofouling in the next step, reverse osmosis (RO).<\/li>
  3. The first RO step extracts about 98% of all salts from the water, as well as all sorts of natural and non-natural organic matter.<\/li>
  4. A second RO step then removes 98% of the remaining salts from the water. Finally, an electro-deionisation system extracts the last remnants of salt.<\/li><\/ol>\n\n\n\n

    After which the water is almost 100% H2<\/sub>O. <\/p>\n\n\n
