Huuhhtelumenetelmät

Huuhhtelumenetelmät refers to a category of wastewater treatment processes primarily focused on removing suspended solids and other particulate matter from water. These methods typically involve the use of a filtering medium or a physical barrier to capture unwanted particles. The term itself is Finnish and directly translates to "rinsing" or "flushing" methods, implying a process where water is passed through something to cleanse it.

Common huuhhtelumenetelmät include sedimentation tanks, where gravity is used to allow heavier solids to settle to the bottom, and filtration, which employs porous materials like sand, gravel, or synthetic membranes to physically strain out particles. Screening, using screens or grates, is another form of huuhhtelumenetelmä used to remove larger debris from wastewater. The effectiveness of these methods depends on the size and density of the particles to be removed, as well as the design and operational parameters of the specific huuhhtelumenetelmä employed. These techniques are often employed as preliminary or primary treatment stages in larger wastewater treatment plants, preparing the water for further, more advanced purification steps.
