The Busse MBR technology reliably ensures the cleaning and disinfection of domestic waste water by a stable biological process and the membrane barrier. Due to this the waste water is made fit for use as re-use water.
The operating costs of the plant are only a fraction of the costs for drinking water and the charges for waste water. Therefore recycling is an ecological alternative – especially as the re-use water can be used for watering the garden or flushing toilets. With additional modules it can also be used for washing machines or to fill up pools, etc.
With plants from about 20 inhabitants the use of the residual heat from the waste water is also possible.

Example calculation for waste water recycling
Apartment building 5 x 4 people equivalents (PE) = 20 PE
Drinking water supply fees + waste water discharge fees (incl. VAT) 5.70 EUR/m³
Service water recycling for washing machines and toilets 1.2 m³/d x 365 d = 438 m³
Operation costs ca. 500 EUR
Saved fees (in drinking water supply and waste water discharge) 438 m³ x 5.70 EUR/m³ = 2500 EUR
Potential for saving enegry costs (optional) ca. 3500 kWh/a{:}
