Filtration equipment and systems range from simple bag and cartridge filters to ultrafiltration systems. However, the goal of any filtration system is the same: the separation of the various components of a liquid.
Bag filters consist of a mesh or felt bag held in a pressurized filter housing where the water flows from the inside to the outside of the bag, so spent bags are easily disposed of. These filters are used for sediment removal in a variety of applications. Cartridge filters are also used for removal of sedimentation, and rely on either a pleated surface-type cartridge or depth-type cartridge held in a pressurized filter housing.
A self-indexing filter has a header that distributes influent water over a section of a roll of filter media. The solids collect on the filter media, while the water passes through and is collected in the tank. As the filter media becomes fouled, the used section is discharged and a new section is automatically indexed into place.
Ultrafiltration systems can be used for separation of particulate and oils from water, but can also be effective in clarifying liquids such as juices by separating the water from the concentrate. Ultrafiltration is a process whereby liquid is passed through a semi-permeable membrane. Water and some solutes become the permeate, while the components to be removed (oil, solids, concentrated juice, etc.) are left behind as concentrate.
Filtration systems are used in a huge number of applications, from manufacturing and food production, to wastewater treatment.
