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.
