Issue

Insufficient wastewater quality

Wastewater does not meet the required quality.

More than 50% of the Dutch surface water does not meet the set standards for the concentration of nutrients. Besides that, WWTPs very limited remove micropollutants, such as medicine and pesticides, from wastewater.

Solution

O3-STEP filter

The O3-STEP filter is a water purification concept, it combines ozone treatment with the 1-STEP® filter (a specialized activated charcoal filter). It removes floating fabric, nitrate, phosphate and micopollutants from the water.

Pros

  • Compact and robust construction.
  • Cost effective.
  • Future-proof: the effluent of the O3-STEP filter meets the future standards.
  • Combination of proven standalone techniques.
  • By using enabled ozone oxidation there is a Increase of removal efficiency and activated charcoal stand time.
