Title: Innovations by Geert Nyhuis in Wastewater Treatment
Introduction
Geert Nyhuis, a renowned inventor based in Gommiswald, Switzerland, has made significant strides in the field of wastewater treatment. With a total of four patents to his name, Nyhuis has developed innovative methods that enhance the biological cleaning processes in wastewater management systems.
Latest Patents
One of Nyhuis's latest inventions is a "Method for Biological Cleaning of Wastewater." This invention outlines a procedure in an activated-sludge plant that involves contacting wastewater with activated sludge in an activated-sludge tank to achieve effective cleaning. Afterward, the cleaned wastewater is separated from suspended activated sludge through sedimentation in a secondary clarification tank. His method also includes mixing growth bodies with the activated sludge to promote the formation of a biofilm of microorganisms on the growth bodies.
Another important patent is the "Method and Installation for Treating Wastewater Containing Ammonia." This system incorporates a hydrocyclone that separates activated sludge from the aeration tank into heavy and light fractions. The heavy fraction primarily consists of anaerobic ammonia-oxidizing bacteria (anammox), while the light fraction contains aerobic oxidizing bacteria (AOB), which are then returned to the aeration tank. The design of the hydrocyclone features a roughened inner wall surface to help remove any covering layer on the anammox bacteria.
