1. Introduction and general instructions
AQUALOOP components are designed for water treatment / sanitation of wastewater. The following types
of raw water can be treated and sanitised with AQUALOOP:
-Clear water
-Surface and ground water
-Clear discharge water
-Grey water
Five AQUALOOP components are combined and dimensioned depending on the existing input water
quality or use.
The updated application range of all AQUALOOP components, along with their application examples, and
the operational dimensioning of each AQUALOOP component related to treatment, water quality and
required tank volume for the bioreactor and clear water tank, can be found at:
http://www.intewa.de/en/products/aqualoop/technology/dimensioning/
General background knowledge for water treatment and grey water utilization can be found at:
http://wiki.intewa.net/index.php/Wasseraufbereitung_und_Grauwassernutzung/en
This manual describes the assembly, settings and start-up procedure of the membrane assembly, which is
the basis of each application.

2. Safety instructions
This installation and operating manual of this device is to be read carefully before installation. The
specified instructions are to be followed exactly otherwise any respective warranty claim may be voided.
This also applies to any separate modifications made to the mechanical and electrical components.
The electronic housing of the current-carrying components may only be opened by a
certified electrician or approved installer.
The electrical circuit used for the system must be secured by a circuit breaker (16 A). Likewise, an ELCB
(earth leakage circuit breaker), with the maximum operating current is to be inserted, if not already
present.
The owner/operator is responsible for compliance of safety and installation provisions.
3. Guidelines, testing, environment
All electric components design and construction, as well as the circuitry, comply with the basic safety and
health standards of EC guidelines for machines. This declaration of validity lapses with any modification of
electronic components not approved by us.
The components particularly fulfil the following specifications of EU guidelines:
EC guideline machines (89/392/EEC) as amended in 91/368/EEC
EC low voltage guideline (73/23/EEC)
EC guideline electromagnetic compatibility (89/336/EEC) as amended in
93/31/EEC
The conformity of components to the above E guidelines is confirmed by CE symbol.
Applied harmonised EU standards:
EN 60335-1: 1194/A1/A11/A12/A13/A14, EN 60335-2-41: 1996
Test symbol: DC switching power supply
Kindly recycle the packaging in an environment-friendly way.
Do not dispose of the electronic components in domestic trash! According to European
Guidelines 2002/96/EC on electronic and old electronic devices and their application in
European countries, components should be collected separately and disposed through
the use of environment-friendly recycling.

6.2 Operation mode display
With different applications, one differentiates between two operating modes:
•Aeration / treatment mode
•Filtration / Pump cycle mode
The biological treatment is done in the aeration mode. Aeration mode does not run permanently, but is
run at intervals to save energy. The exact functioning is set by the controller. If aeration is not required (for
instance, with rainwater treatment) then the ventilation parameter is set (Air ON/OFF = 0/0).
The biologically treated water is filtered via membranes in the filtration mode and routed to the clear water
tank. The filtration start time (T1/T2) and filtration duration (A1/A2) can also be separately adjusted.
Neither aeration nor filtration operations occur in pause mode.
