Mode of operation

The water recycling system operates using the
fully automatic, biomechanical method. It
comprises four phases with seven functions.
Phase 1: Prefiltration
1. Filtration with automatic backwashing
a) The grey water is first prefiltered and
•
then flows into the system, i.e. stage 1.
The filtration prevents coarse solids in
the wastewater, such as hair, textile
fluff etc., from entering the system. It
also reduces the contamination for the
biological purification.
b) Over time, the solids and biological
•
incrustation may foul the filter. The filter
is flushed by a jet from above, fully
automatically. The dirty water flows
directly into the drains, some of it flows
back into stage 1.
Phase 2: Pre-recycling (stage 1)
Phase 3: Main recycling (stage 2)
2. Biological purification (phases 2+3)
Pre-purification of the water takes place in the
first stage 1. After a treatment time (batch time)
of several hours, it is pumped to the second
stage for further treatment. In both tanks the
water undergoes biological treatment with the
supply of atmospheric oxygen. In the process,
natural biocultures (microorganisms) colonize
on special substrate. They attend to the actual
cleaning work. The purification is automatically
controlled, i.e. at regular intervals (batch time)
the water is pumped from tank 1 to tank 2 and
to stage 3 via the UV disinfection device.
Running-in phase:
In the first weeks of operation, the
microorganisms form and multiply of their own
accord.The substrate does not have to be
specially inoculated with biocultures. During the
first 14 days, the system conducts the treated
grey water into the drains through the overflow
of the sediment extractor of stage 2. During this
running-in phase, the consumers are supplied
by the fully automatic drinking water top-up.
After the running-in phase (factory setting 14
days) the system control changes over
automatically to recycling mode.
3. Automatic sediment extraction
The biological treatment produces sediment
which settles in stages 1 and 2. The sediment
is extracted fully automatically at regular
intervals (factory setting 4 days) and conducted
into the drains.
Phase 4: UV disinfection

Operating Manual AC 3000-13500
4. Disinfection
The water is disinfected by UV radiation as it is
pumped from stage 2 to stage 3 (clear water
chamber). The UV-C light of the UV lamp
affects the nuclei of germs contained in the
water. This system is also used in drinking
water treatment. After having been treated in
this way, the water is available in stage 3 in the
form of hygienically innocuous, odourless,
storable clear water for further use.
5. Pressure boosting
A pressure booster unit is required for supply of
the consumers. The pressure booster does not
form part of the grey water recycling system.
A standard pressure booster unit can be used.
A potential-free contact is available to ensure
dry-running protection of an external pressure
booster unit.
The layout of the pressure booster unit must be
attended to by the customer in keeping with the
on-site conditions (building, consumers etc.).
6. Top-up
If there is insufficient clear water available in
stage 3, it is topped up fully automatically by a
defined volume of process water via an open
outlet according to DIN 1988. Infeed takes
place when the min. level is reached in stage 3.
It may be the case that the top-up is activated
several times until tank 3 can be filled from tank
2. We recommend that the drinking water top-
up line is fitted with a strainer to protect the
solenoid valve.
7. Connection to drains
The overflow/outlet has to be connected to the
drains via a trap (e.g. a siphon trap not included
in delivery). The sediments and cleaning water
for the filter flow off through this overflow. In
this way, sediments and solids from the filter
enter directly into the drains.
