The cellulose-based media are available in two forms. Flat sheets, in a number of sizes and profiles, are for installation in filter presses. Lenticular filter cartridges are for use in fully enclosed systems. In all cases, additional filter aids such as diatomaceous earth, polyviny / polypyrolidone and activated carbon may be incorporated within the media to enhance specific adsorptive effects. The media are designed to be sanitized and cleaned using hot water and a variety of chemicals. Steam sterilization is possible for selected types. Lenticular cartridge filters alleviate many of the maintenance and operational issues associated with sheet filter presses. Lenticular cartridges from domnick hunter also incorporate features that combat problems associated with earlier designs such as eccentricity between individual cells, poor wet strength, inability to backwash and dimensional change during use.
