The new Guarantor filter of the Kaskad-APT series with broad functions.
The water purification filter in which practically all advantages of processes of filtering, regeneration, loading of filter medium, aeration of the purified water and dumping of excesses of air from the filter are structurally solved is developed. Patents No. 2201901 and No. 23870 "Device for water purification". What shortcomings the existing designs of filters possess?
1. The drainage system located on the central drain pipe of the filter creates conditions of uneven water flow and formation of stagnant zones therefore the modes of filtering and regeneration worsen. The filter medium after regeneration contains pollution which worsen quality of the purified water in stagnant zones. Often quality of the purified water after regeneration at the beginning of cycle of filtering is worse than quality of the purified water. For the purpose of providing more uniform distribution of water flow in the lower part of the filter the drainage plastic cone is filled up with coarse gravel height the 10-15th that improves hydrodynamics a little, but at the same time reduces the volume of charge of filter medium by this size. In such filters always flow rate on the periphery is less, than in the central part.
1. Filter body. 2. Control unit. 3. Water flows. 4. Central drain pipe. 5. Lower drainage,
6. Gravel. 7. Filter medium.
In the filter there is no system of dumping of air and in case of need water aeration, at its cleaning of iron and/or manganese, the additional aeration column is required.
Guarantor filters of the Kaskad-APT series are deprived of these shortcomings at the expense of drainage systems which create uniform flows on all volume of the filter.
Body of the Guarantor filter.
The system of aeration of water by air with dumping of its excesses into the atmosphere by means of sbrosnik of air which is presented on photo of the Guarantor filter is built in the body of the filter.
The filter mediums made by CJSC Academy of Perspective Technologies including the bactericidal material APT-4 which is the only bactericidal filter medium made in Russia are loaded into the filter.
