This cleansing also increases water visibility and filters out pollutants. Each quagga and zebra mussel filters about 1 litre (1 US quart) of water per day when confined to small tanks. [67] In lakes, their filtering effects are usually spatially restricted (near the lake bottom) because of nonhomogeneous water column mixing.
A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation, accessible drinking water, public and private aquariums, and the safe use of ponds and swimming pools .
Ballast water discharge typically contains a variety of biological materials, including plants, animals, viruses, and bacteria.
