1. Filterung unit with automatic backflush

a) First of all grey water is filtered, to avoid that rough contents like hair, textile fluffs etc pass through to the system. This reduces the impact on the biological cleaning in the first tank.

b) By time the filter can be polluted by the filtered material. Thus process water out of the 3rd tank is used to flush the filter in a certain time range (factory setting 4 days). The accumulated waste water is directly supplied to the drain.


Stage 2

2. Aerobe-biological cleaning (tank 2+3)

Water is pre-cleaned in tank 1 (pre-recycling chamber). After a several hours treatment (factory setting 3h) for further cleaning it is pumped into the 2nd tank (main recycling chamber). In each tank water is treated biologically under aerobe circumstances (supply with atmospheric oxygen). There natural biocultures (microorganisms) settle down on special floating carrier material. They actually perform the cleaning. The treatment is automatically controlled, viz in regular time range (factory setting 3h) water is pumped from tank 1 into tank 2 and respectively for sterilisation into tank 3.

Running-in phase:
The biocultures develop and increase in the first 2-3 operating weeks. There is no need for special inoculation of the biocultures, as well as no maintenance. During this phase the system treats the accumulated grey water, but supplies it via the overflow to the drain. Your applications automatically will be supplied with the fully-automatic fresh water feed. After ending the running-in phase (factory setting 14d) the recycling mode automatically is activated.


Stage 3

3. Automatic sediment disposal

Through the biological treatment sediments erase, which displace in the tanks 1 + 2. They will be automatically sucked out in constant time range (factory setting 4d) and supplied to the drain.


Stage 4

4. UV-Sterilisation

The sterilisation happens via a UV-lamp during the transfer of water from tank 2 to tank 3. The UV-C light affects the nucleus of germs. This technology is also used in the drinking water treatment. Afterwards, the water (= clear water, process water) is hygienically harmless, odourless und storable for further use.

5. Pressurizing pump

The installed pressure pump offers the process water with a maximum pressure of 4.6bar (basic version) for the applications. The pump is activated via a press switch, as soos as an application e.g. toilet flushing is used (see point 1b).

6. Freshwater feed

If there is not enough clarified water available, a defined quantity of drinking or process water is fed in via a free outlet according to DIN 1988. Re-filling occurs when a minimum level is reached in the 3rd module. It may happen that re-filling is activated several times before filling by the 2nd module occurs. We recommend the installation of a dirtfilter into the drinking water re-filling in order to protect the magnetic valve.

7. Overflow

The overflow is connected to the drainage system via a drain trap (e.g. siphon (not included in the delivery specification)). Sediment removal and filter cleaning are carried out via the overflow. Sediment and solid matter from the filter can thus be fed directly
into the drainage system. If more water is produced than the plant can hold, the excess water is fed directly into the drainage system via the overflow.
