  • Page 3: Introduction

    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.

  • Page 4: Dimensioning And General Description For The Aqualoop Gw Series

    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.

  • Page 32: Installation And Connection

    Installation and connection General requirements: dry, frostproof and ventilated room contact area of the tank have to be smooth and even distance between tank and ceiling minimum 0,9 m for maintenance purpose a floor drain has to be provided near the installation the electric pump cables should be measured to ensure that the entire membrane station can be extracted without first having to disconnect the wiring from the controller.
  • Page 33 It is recommended that the sewerage overflow drainage is vented externally to prevent any unpleasant odors. If the system is installed below the backwater level*, then the overflow must be routed to a pumping station, so that the water above the backwater level can be pumped to the drainage via a tube loop. Look for a pumping system with sufficiently large pumping characteristics.
