The filtration system is used for small water treatment system or by private companies. The filter media are replaced every six months to five years. Although these used filter media can be recycled if they are washed and rehabilitated. However, 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. Therefore, we developed the “SIPHON TANK,” which is a filtration system that can produce filtered water of stable 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.
Replacement of filter media is not necessary anymore.
The combination of SIPHON WASHING system which is kneading washing among filter media particles and backwashing keeps filter media always clean in the tank. Therefore, periodical filter media replacement is not necessary.
Since filter media are always kept clean, consistent water quality can be achieved.
SIPHON TANKs can keep filter media as same as the condition of new sand. Therefore, consistent filtration is possible. In addition, since SIPHON TANKs have a structure that prevents unevenness of supporting gravel. Therefore, the problems due to unevenness including short pass do not occur. The amount of filter media flowing out due to sludge deposit is also reduced and the capacity to capture suspended substances does not deteriorate.
Maintenance cost is dramatically reduced.
“Cost for filter media replacement work,” “cost for disposing of used filter media as industrial waste,” and “cost for purchasing new filter media for replacement work” are not necessary. Therefore, maintenance costs can be dramatically reduced.
The amount of backwash water can be significantly reduced.
Since SIPHON TANKs exfoliate hard adhering suspended substances by SIPHON WASHING and conduct backwashing only for rinsing the suspended substances away, the amount of backwash water volume can be significantly reduced in comparison with the conventional filtration systems.
SIPHON TANKs serve as a large stepping stone to the achievement of Zero Emission.
Filter media can be used semi-permanently. Therefore, there is no need to dispose of used filter media as industrial waste anymore. SIPHON TANKs are “eco-friendly” filtration systems that significantly contribute as a solution to environmental problems and response to ISO14000.
Water quality as maintenance cost can be significantly reduced.
Suspended substances never accumulate in filter media. The accumulation of suspended substances due to longtime use and the fixation of filter media to each other due to organic matters, etc. can be prevented. Therefore, water quality is always stable, so that risks necessary to maintain water quality can be alleviated. As a result, the costs for water quality analysis or analysis of the status of filter media can be significantly reduced.
Fixation of filter media is prevented.
Since fixation of filter media is prevented, SIPHON TANKs can be used not only for water supply but also for sewage/wastewater treatment.
SIPHON TANKs reduce work load in the following facilities.
Treated water by SIPHON TANK is stabilized so that the burden on the subsequent membrane system can be reduced and extended its life.
Maintenance of SIPHON TANKs is easy.
Cartridge-type screws are used for SIPHON TANKs. Therefore, the maintenance work is easy.
SUS304 is used for the wetted part.
For the wetted part, SUS304 is used under the standard specifications. Since Steal Strength (SS) coated with epoxy tar, etc. is used for filtration systems in general, the significant cost and time is necessary for curing. However, such mending of coating is not necessary for SIPHON TANKs..
