2.1. How it works

How the process works
The water recycling system works with an
automatic, biological-mechanical process. It
covers four phases with seven functions.
Phase 1: Pre-filtration
1. Filtration with automatic backflush
The grey water is filtered and then flows
•
into the system. The filtering prevents
coarser waste water content such as hairs, textile fluff etc. from entering the system. It
also reduces the load for the biological
treatment.
The waste water contents can contaminate
•
the filter over time. The filter is
automatically flushed from above via a
nozzle. The dirty water present flows
directly into the sewer.
Phase 2: Pre-recycling (Stage 1)
Phase 3: Main recycling (Stage 2)
2. Biological treatment (Phase 2 + 3)
The water is pre-treated in the first stage (pre-
recycling chamber). After several hours
treatment time, it is pumped into the second
stage (main recycling chamber) for further
treatment. In both stages, the water is treated
biologically with the addition of atmospheric
oxygen. Here, natural bio-cultures (micro-
organisms) colonise special, free-floating
carrier material. They perform the actual water
treatment. The treatment is automatically
controlled, i.e. the water is pumped at regular
intervals from Stage 1 to Stage 2, and via the
UV hygienising to Stage 3.
Run-in period:
The micro-organisms develop and multiply
themselves during the first weeks of operation.
The carrier material does not need to be
inoculated separately with micro-organisms for
this. The system transfers the treated grey
water into the sewer during the first 14 days via
the overflow of the main recycling chamber.
During this run-in period, the consumers are
supplied by the automatic rainwater and
drinking water feed. After the run-in period
(factory setting 14 days), the system
automatically switches over to Recycling
mode.
3. Sediment extraction / tank cleaning
The biological treatment produces sediments
that settle in Stages 2 and 3. These are
removed by suction at regular intervals, and
are transported to the sewer.
Phase 4: UV hygienising (Stage 3)

Operating Manual AquaCycle 2500
4. Hygienising
The water is hygienised by a UV lamp while it
is pumped from Stage 2 to Stage 3 (process
water chamber). The UV-C light of the UV
lamp influences the nuclei of the contained
germs. This technology is also used in drinking
water treatment. Following this treatment, the
water is available for further use as
hygienically safe, odour-free, storable process
water.
5. Pressure boosting
A pressure booster station is required in order
to supply the consumers. The pressure
boosting equipment is not part of the grey
water recycling system. An ordinary pressure
booster station can be used in order to boost
the pressure.
A potential-free contact is available on the
controller in order to ensure protection for an
external pressure booster station against
running dry.
The design of the pressure booster station
must be compatible with the situation in the
customer's building (the building itself,
consumers etc.).
6. Feed
If insufficient process water is available, a
defined quantity of drinking water (or rainwater)
is automatically fed in via a free outlet in
accordance with DIN 1988. The water is fed in
when the minimum level is reached in Stage 3.
It may be that the feed is activated several
times until Stage 3 can be filled again from
Stage 2. We recommend installing a dirt filter
in the drinking water feed pipe to protect the
solenoid valve.
For safety, a redundant-acting, electrically
operated shut-off device can be installed
upstream of the drinking water feed, receiving
a signal from the controller.
7. Connection to the sewer
The drain is connected to the sewer via an
odour trap (e.g. siphon, not included in the
scope of delivery). The sediments and the filter
backflush water are flushed through this drain.
As a result, sediments and solids from the filter
enter the sewer directly. If there is more water
than the system can hold, the surplus water
flows through the overflow directly into the
sewer.
