1. Introduction
INTEWA AQUALOOP Greywater Recycling Systems produce an effluent that successfully met the
performance requirements established by NSF/ANSI Standard 350 Class C for multi-family and commercial
scale.
With greywater recycling, water from showers, bath tubs, hand basins, and washing machines is collected
and processed for reuse in toilet flushing, spray irrigation, laundry, cooling tower make-up, and household
cleaning purposes.
The NSF 350 (Class C) listing covers AQUALOOP models with capacities up to 5400 litres (1428 gallons)
average daily flow. According to the official NSF Listing, AQUALOOP for greater capacities can be designed
for system sizes dimensioned and approved by INTEWA GmbH in accordance with the NSF certification.
These designs must follow the dimensioning guidelines given in the Annex.
This manual describes the sizing, assembly, settings, start-up procedure, and maintenance of AQUALOOP
greywater recycling including a troubleshooting guide.
2. Dimensioning and General Description
AQUALOOP models are sized for daily flow capacities from 300 litres (79 gallons) to 5400 litres (1428
gallons) per day. The capacity is determined by membrane cartridge throughput, blower volume, tank size,
and amount of growth media.
The AQUALOOP membrane station can be equipped with up to 6 membrane cartridges. In the standard
greywater application, 300 litres (79 gallons) per day is filtered using a single membrane cartridge. One fully
equipped membrane station (using 6 membrane cartridges) generates a daily flow of 1800 litres (476
gallons) per day.
As with the number of membrane cartridges, the bioreactor (treatment tank) size, aeration volume
supplied by the blower, pre-filter size, and amount of growth media required depends on the daily volume
of greywater to be recycled. A minimum treatment rate table is provided below for all NSF 350 (C) listed
models.

Depending on the cleaning interval a single membrane cartridge can produce up to 900 L/day (238 GPD). A
fully equipped station can therefore produce up to 5,400 L/day (1428 GPD) with associated tank, aeration,
and growth media dimensioning. Such dimensioned systems are equipped with automatic cleaning. These
systems, dimensioned for a higher daily throughput, are described in the Annex.

2.1 Functional Description
Fig.: Example installation layout of AQUALOOP Greywater Recycling System
The greywater (1) from the bathroom (bath tub, shower, basins) and washing machine outlets is first
filtered by the pre-filter (2) and then enters the bioreactor (3). In case the bioreactor is full of water, the
greywater overflows into the sewer (11) via the filter overflow. If the water level has reached its maximum
capacity, the water overflows through the integrated skimmer on the pre-filter to remove the floating
debris (foam, grease, oil) from the surface of the water. The sludge pump (4) is used for regular sludge
removal of the system. The sludge pump outlet is routed into the sewer via the overflow.
In the bioreactor, the greywater is treated biologically (aeration + growth bodies). The aeration is provided
by the blower (5) and regulated by the AQUALOOP controller (6). The aeration pipe is connected on the
bottom side with the membrane station (7). The aeration has two functions: Aeration for the biological
water treatment and for the cleaning of the membrane fibres through an air scour.
After biological treatment, the membrane station controller operates the ultra-filtration process where
clean water is pumped to the holding tank (8). Filtration transfer alternates between suction and backwash
to further keep the membranes clean.
The minimum level of the bioreactor is controlled by a level sensor. The filtration process is interrupted, if
the minimum level in the bioreactor is reached or if the maximum level in the holding tank is reached. The
bioreactor is ventilated by the vented greywater inlet pipe (1) or by a separate vent pipe.

2.2 Influent quality
The AQUALOOP System Greywater Recycling is designed for greywater treatment.
Greywater as certified for this listing is combined bath, laundry, and bathroom sink water. Toilet,
dishwasher, and kitchen effluent are excluded from this listing due to high contaminant load in the form of
BOD and TSS and must not be connected to the AQUALOOP system. See influent requirement limits
below.
Permitted use of the following detergents and cleaning products:
All usual personal cleaning products (soap, shampoo, shaving cream, toothpaste etc.) have to be
biodegradable.
Detergents for washing machines should have low phosphate, low salts and be biodegradable.
Refer to manufacturers for more information.
All household cleaning agents should be used in accordance with the manufacturer’s safe home use
directions.
Attention:
Water quality should be monitored to assure the following substances are not introduced
to the system. Function of the membranes and the system in general may be hampered
if excessive quantities enter the system and equipment damage can occur.
Water inlet qualities and substances which are not allowed:
Water from toilets and kitchens must not be fed to the system.
Fats, oils, and greases
Chemicals such as paints, thinners, and cleaning chemicals may interfere with operation and msut
be avoided.
Hair dyes can cause discoloration of the filtered water and must be avoided.
Note:
Influent greywater quality shall not exceed NSF/ANSI 350 test levels (systems treating bathing and laundry
source waters combined). The parameters of the greywater delivered to the system must be as follows:
Parameter

2.4 Certification NSF/ANSI 350
The systems AL-GW300 to AL-GW5400 (300 - 5400 L/day) (79 - 1428 GPD)
are NSF certified according to NSF/ANSI 350-2014.
For systems larger than 5400 L/day (1428 GPD) (or systems which are built
with local tanks), INTEWA is entitled to issue an NSF Declaration of
Conformity which entitles the user to carry the NSF certificate with no local
field test required. For this purpose, INTEWA performs a plant-specific
verificat
ion of compliance with the specifications of the INTEWA NSF
report. See the confirmation of the official NSF listing. In case of working
with INTEWA indoor tanks, those larger systems are to be designed by using
multiple AL-GW600 to AL-GW5400 systems. In case of using local tanks, the
systems are linearly upscaled according to the scale up procedures outlined
in the Annex for parallel membrane stations, aeration volume, growth
media, and pre-filter sizing.

6.1.2. Multiple Membrane Station Controller with Remote Monitoring and Control
The multi-station controller is for commercial scale applications where multiple AQUALOOP stations are
required. The base unit accommodates up the three AQUALOOP stations and controls all system functions
and monitoring. Expansion units each add control up to three additions stations. The local interface is touch
screen. The panel connects with building management systems via MODBUS or BacNet connectivity.
Through the https://connect.intewa.com link, full remote programming, control, monitoring and history is
possible, depending on level of access.
