Wastewater treatment technology encompasses components and systems for the mechanical, biological and chemical treatment of wastewater in municipal and industrial treatment plants. Key areas include treatment tanks (primary clarification, aeration tanks, secondary clarification tanks) and agitators (submersible, vertical and hyperboloid agitators) for mixing and oxygenation.
Pumps for wastewater treatment (sewage, sludge and submersible pumps with cutters) are used for water transport. In the field of sludge treatment, sludge thickeners, centrifuges, screw presses and digesters are used for volume reduction and energy generation from biogas.
Leading manufacturers include ANDRITZ, Sulzer, Grundfos, KSB, Wilo, Huber, Aerzen, Flygt and Wamgroup.
Wastewater treatment technology is used in municipal sewage treatment plants, in industrial wastewater treatment (food, paper, chemicals), in decentralised small-scale sewage treatment plants, and in treatment plants for service and process water.
