General notes
Read these operating instructions before using the system for the
first time. Also observe the original data sheets provided in the
appendix and the operating manuals for the units used. Keep
these documents for future reference or for future owners.
Target group for these instructions:
Operator
Technical specialists (persons possessing the necessary techni-
cal training allowing them to erect and commission the system)
Instructed assistant personnel
Definitions:
Fresh water is tap water.
Waste water is the dirty water coming from the washing facility.
Recycling / processed water is the treated water coming from
the treatment system that is re-used in the vehicle washing fa-
cility.
Running-in phase BioSaver®/ WRB Bio
The system requires a running-in phase of 3-6 weeks in order to
develop its full cleaning performance. The running-in phase be-
gins on the day when waste water containing treatable substanc-
es (mineral oils and company-internal waste water) is regularly
channelled into the system. During the running-in phase, the mi-
crobiological system can temporarily produce increased quanti-
ties of foam in the washing facility. Do not supply any heavily
contaminated waste water into the system during the running-in
phase.
Note
It has been observed that the drainage channels in the washing
halls and the sludge traps of the separator system are misused
for disposing of waste during the installation process. To prevent
system malfunctions during operation, such as clogging or dam-
age to the pumps, clean all foreign materials from the drainage
channels before channelling waste water into the system for the
first time.
Note
The waste water resulting from the cleaning of buildings (walls,
floors, containers etc.) may not be cleaned in the treatment sys-
tem. The system is not designed for processing or disposing of
this type of waste water.
aquadetox international GmbH accepts no liability of any kind for
damage or operational malfunctions resulting from inadequate
cleaning of the entire system.
Intended use
The BioSaver®/ WRB Bio is a biological process for waste water
treatment. The system is intended for cleaning and recycling the
waste water generated by various different types of vehicle wash-
ing facilities. The recycling water may only be used for washing
programs (e.g. pre-cleaning, high-pressure cleaning, brush
cleaning).
The waste water is cleaned through:
Settling of non-soluble particles in the sludge trap
Separation of the excess sludge in the post-treatment stage
Substance transfer of the soluble substances in the biological
stage
Environmental protection
The packing materials can be recycled. Please dispose of
packaging in accordance with the environmental regula-
tions.
Electrical and electronic devices contain valuable, recycla-
ble materials and often components such as batteries, re-
chargeable batteries or oil, which - if handled or disposed of
incorrectly - can pose a potential danger to human health and the
environment. However, these components are required for the
correct operation of the device. Devices marked by this symbol
are not allowed to be disposed of together with the household
rubbish.
On renewal of the filter material, the used filter material must be
disposed of in accordance with the applicable local regulations.

Auxiliary materials and additives
The BioSaver®/ WRB Biooperates without the use of auxiliary
materials or additives. Using these substances can permanently
impair the biological cleaning, e.g. in emulsion splitting, ozone or
filter treatment systems.
Operating times
The function of the BioSaver®/ WRB Bio is based on living micro-
organisms that always require a certain minimum amount of oxy-
gen. This is why the system must continuously remain in opera-
tion, also at night, on public holidays and other standstill periods
of the connected washing facility.
To keep the energy requirements as low as possible, the auto-
matic control system is programmed to independently detect the
volume of incoming waste water and dynamically reduce the run-
ning time of electrical units during low load phases, such as at
night, on Sundays or public holidays.
Impermissible substances
The following substances are not permitted:
Precipitants and flocculation agents
Disinfectants (also not as cleaning agent additives)
Chlorine tablets
Defoaming agents
Special care must be taken when using cleaning agents specially
offered for use in recovery systems. These agents are often
mixed with disinfectants, precipitants and artificial aromatic
agents to compensate for known problems such as odours in re-
covery systems.
With the BioSaver®/ WRB Bio these problems do not occur. The
use of such agents is therefore pointless and questionable.
Please contact your customer service partner responsible in the
case of any uncertainties or questions regarding the usability of
cleaning agents.
Detergent
The BioSaver®/ WRB Bio can only remove biologically degrada-
ble components from the waste water, e.g. mineral oil. Many
cleaning agent additives are not biologically degradable or diffi-
cult to biologically degrade and impair the waster water cleaning.
Fundamentally, only cleaning agents for which the associated
safety data sheets have been checked to ensure that they do not
cause malfunctions in a biological waste water treatment plant
may be used and these must also at least satisfy the require-
ments of the German Washing and Cleaning Agents Directive
(WRMG). Request the manufacturer's cleaning agent data sheet
in the case of uncertainties regarding selection of a cleaning
agent.
Note
Within the scope of an official inspection of your commercial
premises, you are obliged to present the safety data sheets for all
consumable materials used. This also includes all cleaning
agents used.

Sludge trap servicing
Check the sludge trap and pumping station (option) together.
The sludge level in the sludge traps must be regularly checked
using a measuring disc (inspection set for separating systems).
This is based on the own-monitoring directive (interval depending
on the amount of sludge present). The sludge trap must be emp-
tied by an approved disposal company when 50 % full. The dis-
posal process can stir up sludge that can clog the coalescence
separator (option) or the insertion-sieve boxes.
1. Fill the sludge trap with fresh water after sludge disposal to
prevent a shortage of water in the system.
2. Check the coalescence separator (option) and the insertion-
sieve boxes for soiling over a few days after sludge disposal.
Pumping station (option) servicing
Check the sludge trap and pumping station (option) together.
If necessary, drain and clean the pumping station:
1. Set the pumping station pump to Manual mode/Off.
2. Have the pumping station drained by an approved disposal
company.
3. Remove any deposits from the pumping station if present.
4. Fill the pumping station with fresh water until the pumping sta-
tion pumps are covered.
5. Set the system into Automatic mode.
Insertion-sieve box servicing (standard version)
The insertion-sieve box consists of the insertion sieve and the
baffle plate/immersion wall. The insertion-sieve box is installed in
the discharge channel of the sludge trap upstream of the
1st biological basin and protects the immersion pump from
coarse dirt particles. The insertion-sieve box must be checked
weekly for soiling during operation in order to prevent water from
backing up in the sludge trap.
1Insertion-sieve
2Baffle plate/immersion wall
1. Pull the insertion-sieve box out of the shaft and set it down on
a suitable surface.
2. Clean the insertion-sieve box with a brush.
Biological stage servicing
Note
The aeration units in the stages must be checked for formation of
coatings and deposits after 1-2 years. The pre-treatment sludge
trap may need to be evacuated and disposed of. This work can
only be performed by Customer Service. Contact your customer
service partner responsible regarding this.
