Saito Tank water treatment

For filtration systems now used for small water systems or by private companies, filter media are replaced every six months to five years. Although these used filter media can be recycled if they are washed and rehabilitated, they are usually disposed of as industrial waste due to such problems as space for installing a washing system and costs for washing filter media. In this regard, we developed the Saito Tank, which is a filtration system that can produce filtered water of consistent quality without replacement of filter media. Since filter media are always kept clean, there is no need to dispose used filter media as industrial waste, an improvement from in the past. It serves as a stepping stone to a solution to environmental problems and achievement of zero emission advocated by ISO14000. It is also expected to significantly reduce maintenance costs, including the cost for replacement of filter media and the cost for backwashing.
