DAF systems are considered the best available technology for removal of algae in drinking water treatment plants, as they take advantage of the buoyancy of algae cells. It’s a lot easier to make an algae cell float than it is to make it settle. Furthermore, DAF removes algae from the water column gently, without breaking the cell wall.

Equipment has been developed to solve the algae problem in garden ponds definitively. They function according to the mineralization principle. By mineralization the growth of fibrous and slimy algae is rendered impossible, whereas water plant growth is stimulated. A lasting solution for the floating algae problem (green water) is a UV-C Filter. The ultraviolet radiation will kill floating algae, germs and moulds.

wastewater treatment

Wastewater treatment

Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused. The latter is called water reclamation because treated wastewater can be used for other purposes. The treatment process takes place in a wastewater treatment plant (WWTP
