Leading in greywater recycling

Up to 65% of the water demand of many buildings is used for showering, bathing, washing hands and for the washing machine. The resulting wastewater is the so-called greywater. With AQUALOOP technology, this water is treated in a membrane bioreactor and then stored in a clear water tank. The heat contained in the water can also be recycled via a heat exchanger using a heat pump. The treated water is of excellent quality and is reused for toilet flushing, irrigation and washing machine use by means of a pressure boosting system and further UV disinfection.

Especially for sports facilities, schools, hotels and apartment buildings with significant amounts of shower and bath water and a matching service water demand for toilet flushing, washing machines or irrigation are suitable for a greywater recycling plant. However, many office buildings can also use water from hand washing sinks. Unlike rainwater harvesting systems, greywater systems are independent of roof surfaces and precipitation conditions.

A particular advantage is also that the greywater yield and demand have a good degree of coverage in terms of time. During vacation periods, for example, when less water is needed, less water is produced.

Only a correspondingly small amount of water is also treated. Since a separate greywater and process water piping system is required for greywater recycling plants, new buildings or renovation projects are usually suitable. Here, the separate pipelines cause justifiable additional costs. To allow good accessibility and maintenance of the plant, the installation of the plant should be inside the building.
