1. Introduction
In grey water recycling the contaminated water from shower, bath tub, hand basin and washing
machine is collected and processed for reuse in toilet flushing, garden watering, washing machines and
household cleaning purposes. The storage volume required for a grey water system is very small, as the
water accumulates daily, therefore grey water systems require little space.
The major benefit of grey water recycling: In many countries, customers are levied twice for municipal
water - once for the amount of mains water used and once for the amount sent down the waste pipe. By
installing an AQUALOOP grey water system and re-using your water again around the home, you save
twice as much on your municipal bills.
The AQUALOOP System is specially designed for grey water utilization in commercial applications.
Depending on the number of membrane cartridges connected, it can treat up to 1800 Litres of grey
water per day.
All AQUALOOP components make up the system and are installed by the client in a tank.
This manual describes the assembly, settings, start-up procedure and maintenance of the AQUALOOP
System including a troubleshooting guide.

2. Dimensioning and general description for the AQUALOOP GW series

The AQUALOOP membrane station can be equipped with 1 to 6 membrane cartridges. In the standard
grey water application 300 litres per day is filtered using one single membrane cartridge. One fully
equipped membrane station (using 6 membrane cartridges) generates a daily flow of 1800 litres.
The bioreactor (treatment tank) size depends on the daily volume to be recycled and the blower size
depends on the amount of membrane cartridges utilised.

Fig.: Installation layout of AQUALOOP System GW
The grey water (1) from bathroom (bath tub, shower, basins) and washing machine outflow is first
filtered by the pre-filter (3) and then enters the bio reactor (2). In case the bio reactor is full of water, the
grey water overflows directly into the sewer (6) via the filter overflow. The built in non-return valve
prevents the backflow of water, small animals and vermin from entering the tank. With each overflow of
the bioreactor the ground sediments are automatically extracted through the suction overflow (4) in the
AQUALOOP pre-filter. If the overflow has reached its maximum capacity, the water overflows through
the integrated skimmer and thereby cleans the floating debris (foam, grease, oil) from the surface of the
water. The sludge pump (5) is connected at a further pre-filter connection and is used for cleaning and
maintenance of the system. The sludge pumped outlet is directly routed into the sewer.
In the bio reactor the grey water is treated biologically (aeration/growth bodies). The aeration (9) is
produced by the Blower and regulated by the AQUALOOP control unit (10). The aeration pipe is
connected on the bottom side with the membrane cartridge (8). The aeration has two functions:
Aeration for the biological water treatment and for the cleaning of the membrane fibres themselves.
After the biological treatment the suction pump of the membrane station starts the microfiltration
process and the filtered, clear water is pumped to the clear water outlet. After each suction interval (15
min) the membrane is cleaned with a back flush sequence (15 sec).
The minimum level of the bio reactor is controlled by a floating level switch. The filtration process is
interrupted if the minimum is indicated. The bio reactor is ventilated via a ventilated grey water inlet
pipe (12) or a separate ventilation pipe.

2.2 Influent quality
The AQUALOOP System 300-1800L designed for greywater treatment.
Greywater is only recognized as water from shower, bath tub, hand basin and washing machine! Never
kitchen, dishwasher or toilet water!
Permitted use of the following detergents and cleaning products:
All usual detergents and personal cleaning products (soap, shampoo, shaving cream, toothpaste
etc.) may be used.
All household cleaning agents are safe to use in accordance with the manufactures directions for
home use.
Attention:
Please monitor the water inlet quality and ensure that substances which are not
allowed to enter the bioreactor DO NOT because the membrane filter can
become blocked or possibly destroyed.
Furthermore the outlet water quality can’t be guaranteed for safe reuse in this
case!
Water inlet qualities and substances which are not allowed:
Faeces and kitchen water, fats and chemicals (e.g. paints, thinners ) must not be fed to the
system.
Hair dyes that can cause discoloration of the process water.
Note:
Influent greywater quality shall not exceeded NSF/ANSI 350-2014 test levels (Systems treating bathing and
laundry source waters combined.)
The 30-day average concentration of the graywater delivered to the system shall be as follows:
Parameter Range

Note:
The membrane cartridge has a blower connection (aeration)
and a permeate connection. The membrane cartridge is
always operated in a vertical position, whereby the blower
connection is situated at the bottom. (The air should rise
upwards in the cartridge through the fibre bundles.)
The lower side of membrane used with the blower
connection can be distinguished by the larger holes.
The top side of membrane with the permeate connection is
distinguished by 18 slotted slits and the external interlocking
ring. The blue cover of the cartridge is fixed with this.
Attention: Please check, that the interlocking ring is in the
LOCK position when you mount the membrane in the bio
reactor!
The membrane connections are equipped with an O-ring nut
into which an O-ring is inserted.
