Filterkammaren

Filterkammaren, or filter chamber in English, is a compartment within filtration equipment where a filter medium is positioned and the separation of solids from liquids takes place. The chamber is typically part of a larger vessel or housing and includes inlets and outlets for feed, filtrate, and often a backwash or cleaning connection.

In operation, the liquid containing suspended solids enters the chamber and passes through the filter medium, becoming clarified as it exits through a separate outlet. The retained solids accumulate as a layer or sludge on or within the medium and are periodically removed or flushed out. The design of a filterkammaren supports different filtration modes, such as depth filtration with granular media or surface filtration using membranes or cartridges.

Common filter media found in filterkammaren include sand or other granular media, activated carbon, membranes, or cartridge/bag filters. Variants differ in how the medium is housed, how cleaning is performed, and how backwashing is implemented. Materials of construction range from stainless steel to concrete and corrosion-resistant polymers, chosen for chemical compatibility and mechanical demands. Design features often include access hatches, sealing, manifolds for inlet and outlet, and backwash or cleaning lines.

Filterkammaren are used in municipal and industrial water treatment, wastewater treatment, oil and chemical processing, food and beverage production, and laboratory filtration. They play a central role in removing suspended solids and particulate matter, protecting downstream equipment and improving process quality. Maintenance involves periodic cleaning, backwashing, and media replacement as required.
