Description

The filter storage according to the invention is a system for water treatment in which waste and rain water is filtered and mixed with tap water, whereby the backwashing of the filters is carried out predominantly with rain water.

1.) During the filtering process, dirty water enters the dirty water collection pipe 11 through the inlet 3, is pumped by the pump 13 through the mixing valve 14 through the filters 16 + 21 and is conveyed through the valve 23 into the service water tank 15. The pump 13 is controlled by the float switches 19 and 12. The float switch 19 is controlled in such a way that if too little cleaned dirty water is pumped, fresh water is supplied from the pipe 18. When the pump 13 is operated, fresh air is supplied via the pipe 33, the amount of which can be regulated with the tap 34. This design is necessary to prevent the formation of odors. At the start of the filtering process, the valve 14 is delayed so that dirt that settles in the dirty water collection pipe 11 by sinking is initially conveyed directly into the dirty water outlet 27. After this time-delayed process has ended, the waste water is filtered in the manner described above and fed to the domestic water tank 15.

2.) When backwashing and cleaning the filters, the pump 26 pumps service water through the valve 23, the filters 16+21 through the valve 14 into the drain 27. As the water level in the service water tank 15 drops, rainwater from the rainwater pipe filter 32 can flow through the pipe connection 29 into the service water tank 15. During this process, the service water from the tank 15 is replaced by rainwater from the pipe filter 32.

3.) When filtering and supplying rainwater, rainwater is led through the rain pipe 1 and through the filter basket 6 into the filter pipe 7 and through the gravel filter 8 into the rainwater pipe filter 32 from which it is led through the pipe connection 29 into the domestic water tank 15. If there is a large influx of rainwater, the float switch 10 floats up and switches on the pump 26 for backwashing. If there is little or no rainwater inflow, the rainwater flows from the rainwater pipe filter 32 into the wastewater collection pipe 11 via the bypass 9 and thus reaches the wastewater drain 27.

Claims (9)

Sayings 1.) Filter storage for water treatment of dirt and rainwater characterized in that the filters, the pipe system, the pumps and the necessary units are located in a container in the service water and are hydraulically controlled by the rainwater inlet and outlet according to the principle of communicating pipes. 2.) Filter storage according to claim 1, characterized in that the backwashing of the filters can be carried out with rainwater and the service water pump is controlled by means of a float switch. 3.) Filter storage according to claim 2, characterized in that a connecting line from the rainwater filter to the wastewater drain terminates the backwash process with the float switch if there is no rainwater inflow. 4.) Filter storage according to claim 3, characterized in that 2 submersible pumps alternately filter or backwash the filter via 2 control valves. 5.) Filter storage according to claim 4, characterized in that the inventive design replaces the filtered water during heavy rainfall without using expensive tap water, in order to achieve the formation of odors due to rotting water. 6.) Filter storage according to claim 5, characterized in that oxygen is automatically supplied to the dirty water during the filtering process via an air supply. 7.) Filter storage according to claim 6, characterized in that if there is no rainwater inflow, the necessary water is refilled from the water supply network by means of a float switch. 8.) Filter storage according to claim 7, characterized in that the filter gravel can be sucked out of the filter pipes upwards for renewal. 9.) Filter storage according to claim 8, characterized in that during the filtering process the dirty water pump first discharges the dirty water into the dirty water channel via a three-way valve in order to remove deposited dirt.
