WesTech - MULTIWASH® Filtration Process
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.
WesTech - MULTIWASH® PRO Trough
As part of the WesTech MULTIWASH® family, the MULTIWASH PRO trough can be added to almost any system (WesTech or others) either as a retrofit or upgrade. It is also available for use in new pressure filters and AERALATER® package plants. The MULTIWASH backwash process solves the media fouling and frequent backwash problems that can occur in today`s plants. Its high-performance backwash eliminates mudball formation, media grain coating, and biological fouling without the need for chemical cleaning systems.
