New tertiary process to remove micropollutants and phosphate from municipal treated wastewater tested at WwTW Emmen
A pilot plant has been started at the waste water treatment plant of Emmen, Waterschap Vechtstromen. This pilot study, called Bio-GAK, aims to find an affordable and sustainable solution for removing micropollutants from treated wastewater before the water is discharged into surface water. This method removes both medicine residues and phosphate. Bio-GAK pilot The purification technique applied is using granular activated carbon filter media. The filter bed is aerated to stimulate biological conversion within the filter bed. Hence the regeneration frequency of the carbon filter may be extended. The Bio-GAK process uses the continuous filtration technology. This means that … Read more
