The development of very fine screens for separation of finer particles opens up new fields of application in wastewater treatment. For the new type of membrane bioreactors recently introduced into the market improved performance is required to ensure reliable separation of hairs and fibrous material to allow the process to function effectively.
Another application for these units are river and sea outfalls which frequently only have coarse mechanical screening. It will become more common and important to reduce the COD/BOD concentration of the wastewater discharged into the receiving water course. Undegradable toilet and plastic articles and organic material contained in the wastewater can be removed by these fine screens in a single process step. By application of this new technology a high degree of environmental protection can be achieved at a reasonable expense. For further improvement of the screens' efficiency precipitants and coagulants can be added. They have the effect that dissolved and very fine particles contained in the wastewater are converted into separable particles so that the filterable solids can be reduced by up to 95%, COD/BOD by 65% and phosphorus by 60%. For many regions in the world with insufficient wastewater treatment plants, if any at all, fine screening can be a first and quick step into the right direction.
