DE4036422A1 - Tank for waste water utilisation system - has foam suppressing agent to collector tank with strainer and filtering substance - Google Patents

Abstract

The system for max. use of waste water has a collector tank supplied with the water from a bath, shower, washbasin etc. by a down pipe (11), and a removable strainer (16) retaining the coarse dirt. A biological, foam-suppressing agent is delivered at a variable rate by a nozzle from a vessel (20) into the tank. Before pumping up to a roof tank for use in flushing toilets, the water is cleaned again by a removable filter (17) of fine mesh metal, jute or plastics in a frame. The latter can also contain active carbon or other filter agents. ADVANTAGE - Max. economy in water consumption.

Description

The innovation is that metal water tanks, Concrete, plastic or bricked and lined, spe are specifically equipped for the use of process water.

The process water passes through a downpipe, which is connected to the tank by an inlet connection via a built-in grid in the tank. As well the rainwater via a separate inlet.

At the same time, the outside of the tank is opened dosed amount of biodegradable Foam stopper supplied.

Customs not covered by the wire screen water, as well as some chemical residues, are caused by the sieve covering the entire tank width and height filtered (activated carbon or diatomaceous earth).

The pump connection is after the filter in Height of the base plate of the tank. Overflow pipe and hose connection are also integrated.

Wall thickness and volume of the tanks depend on the Size, which varies according to the number of living quarters calculated.

The shape (round, square or oval) is individual.

With the upper tank, which from the lower tank up pumped domestic water absorbs, are except supply u. Procedure, Fresh water supply (if process water is not sufficient), Control float for inlet and pump float switch for automatic shutdown of the authoritative integrated construction parts. Here too, the size is dependent on requirements.  

The innovation is based on the drawings as follows described:

Fig. 1 shows: The process water collection tank. The downpipe 11 directs the process water from the bath, shower and hand basin into the tank. Coarse dirt is retained there by the wire screen 16 (removable). Through tube 19 , rainwater enters the tank. The container 20 contains biological foam stopper, which is fed to the process water via a variably adjustable nozzle. Before the service water is pumped to the upper tank by the pump 9 by means of the pressure pipe 7 , it is cleaned again by the filter 17 . The filter 17 consists of a removable jute, metal fine mesh or plastic covered frame made of metal, wood or plastic, covered on both sides. Depending on your needs, the frame can be filled with activated carbon or appropriate filter substances. Overflow pipe 10 and From 18 pipe are used for safety and cleaning.

Fig. 2 shows: The service water storage tank attached under or on the roof.

The process water is passed through the pressure pipe 7 into the process water storage tank. Tube 12 leads the process water down to the toilet flush. The control float 13 regulates the supply of fresh water through pipe 14 if necessary. Float switch 15 switches off the pump and thus the hot water supply if the water level is too high. The overflow pipe 21 is connected to the downpipe 11 and thus leads the excess service water back into the lower collecting tank.
