Remove particles that could damage or block downstream equipment.

The DAF flotation units are designed to remove solids, oil, grease and/or flocs from the wastewater.

Microfiltration, ultrafiltration, nanofiltration and reversed osmosis are pressure driven processes. By applying pressure the water flows through the membrane and components with a certain size are retained. These technologies are used for water reuse systems or for recovery of valuable materials components in the wastewater.

The wastewater (after primary treatment) is pumped into the aeration basin, which is filled with an activated sludge/water mixture. Activated sludge are flocks of bacteria, also called biomass. In the presence of oxygen, the pollution in the wastewater will be decomposed by these bacteria. The aeration system is designed to supply optimal conditions in order to decompose the main pollutants present in the wastewater. In general the pollutants are organic compounds, comprising of carbon, hydrogen and nitrogen.
