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:
