filterhuset

Filterhuset is a Swedish term that refers to the building or room that contains filtration equipment within a larger facility, most commonly in municipal water treatment plants. The name translates directly as "the filter house."

In a water treatment context, filterhuset houses filtration basins or modules, backwash systems, chemical dosing equipment, and control and monitoring stations. The design emphasizes accessibility for maintenance, safety, and hygiene, with clear separation from raw water intakes and finished water outlets and with integration to the plant’s power and chemical supply systems.

Outside water treatment, the concept also applies to air filtration or industrial filtration spaces, where a filterhuset may contain filter housings, fans, ducts, or piping. In some Swedish towns, Filterhuset is used as a proper name for a specific building, venue, or cultural space associated with filtration-related heritage or public administration. Regardless of context, the term denotes a dedicated space where filtration processes are housed and controlled.
