The objective of this process is to remove coarse suspended solids that could deposit on process equipment creating scale and corrosion sites. Filtration with coarse filters can typically range from less than 50 microns upwards. Filter cleaning is accomplished using automatic backwashing, and is required when the differential pressure on the unit increases to the point of maximum or the flow becomes too restricted. Maximum filtration area Robust mechanical design Balanced collection nozzles Low friction contact parts
