Once you have selected the right type of filtration system for your application, it's equally important to select the most effective filter internals, such as underdrains, washtroughs, and media. WesTech has more options and expertise than anyone else in the market.
One of the leading options for many years now is the MULTIWASH Filtration Process, which combines air and water simultaneously for the duration of the backwash. The combined air and water wash provides a vigorous scouring action to clean the media while specially designed wash trough baffles are used to eliminate media loss.
The superior cleaning performance of the MULTIWASH process prevents both chemical and biological fouling of the filter media, eliminating expensive chemical cleaning or media replacement.
MULTIWASH Filtration Process was originally developed for wastewater filtration. Deep, large media beds provide longer filter runs while producing comparable effluent quality. Several plant retrofits confirm the powerful backwash provided with the MULTIWASH Filtration Process.
Filter components that support the MULTIWASH Filtration Process include reduced profile underdrains and specially designed washtroughs and collectors.
