SIPHON K3 System
Highly Efficient Washing System for Filter Basin
Filter media at Water Purification Plants in Japan are replaced or washed for reuse every few years. But such work requires enormous expenses and necessitate the stoppage of filter basin operation. We offer a new maintenance system for filter basins. SIPHON K3 System keeps filter media clean, supplies safe water, and helps to reduce maintenance cost and greenhouse gas emissions.
・Filter media flows through filter basin
・Confirmed washing capacity with washing muddy degree test and solubility in HCl test according to JWWA
・Filter media are not crushed: Kept Effective Size (E.S.) and Uniformity Coefficient (U.C.)
Characteristics
- By SIPHON WASHING, filter sand can always be kept in the best possible condition.
- Since filter media is kept clean, the cycle of rehabilitation work recommended by maintenance guidelines (Japan), i.e., “eight (8) to ten (10) year term,” can be extended up to about twice as long, leading to reduction of maintenance costs.
- Since suspended substances are removed, normal backwashing can be realized and the generation of mud balls can be prevented
- Since filter media can always be kept clean, the high treatment capacity, including filtration rate and filter run time, can be maintained.
- Consistent water quality can be achieved.
- SIPHON K3 System can be installed in the filter basin while it is in operation.
Flow of filtration
In the SIPHON K3 System, the water current helps filter media move into the washing machine, filter media is cyclone washed along the interior space, wastewater is drained by over-flow and filter media get slurry suitable for SIPHON WASHING. Filter media accumulated at the bottom is washed by SIPHON WASHING with screw, and return to filter basin again from outlet.
