Rotary Drum Precoat Filters
Rotary drum precoat filters are used to polish liquid solutions with trace amounts of suspended solids. They are similar in appearance to rotary drum filters, but the construction is very different. The drum is precoated with a medium of known permeability and particle size. The contaminated feed
Treating wastewater from CMP using ultrafiltration
in Figure 1, silica particles in an oxide slurry can range in size from 20 to 80 nm, far too small to be retained by microfilters alone. To be effective, cross-flow microfilters need to build up a dynamic layer, similar to a filter precoat. Achieving this buildup frequently requires the addition
