Underground water treatment equipment is commonly known as well water treatment, is mainly removal of iron and manganese, by aeration and filtration, filtration medium is commonly used quartz sand, manganese sand, followed by active carbon and precision filters to proceed filtration, after treatment, the water quality can meet the national standard for drinking water. And ammonia nitrogen mostly adopts by ultrafiltration or reverse osmosis filtration process, sediment and incrusting can be used in multi-media filtration and ion exchange softening device to proceed filtration.
Filtration plays an important role in the natural treatment of groundwater as it percolates through the soil. It is also a major part of most water treatment. Groundwater that has been softened, or treated through iron and manganese oxidation, requires filtration to remove floc created by coagulation or oxidation processes. Since surface water is subject to run-off and does not undergo natural filtration, it must be filtered to remove particles and impurities.
