Wastewater treatment plant a two step process

The Busse MF Small Size Sewage Treatment System is designed on the basis of DIN 4261 part 2 and is comprised of two treatment steps, pre-treatment (1) and aeration (2). At the pre-treatment step, which also serves as wastewater treatment plant storage, biologically degradable coarse material such as, e.g., feces, toilet paper, are dissolved and the non-dissolving components separated from the waste water by an aerated sieve (3). A pump (4) pumps the water, from which the coarse material has been separated, to the aeration section. In this step the organic matter in the waste water is degraded biologically by microorganisms and oxygen (5). In addition to this, the waste water is treated physically by microfiltration membranes (6) (ultrafine filter with 0.1 µm pore size). These membrane filters eliminate suspended material,  ensuring that only totally clear, odorless, hygienically harmless water (filtrate) leaves the system.

The BusseGT  waste water treatment system has passed the certification process of NSF International Standard 40 and 245 for USA and North America in 2008. The test results show that the system elates over 95 % of the COD and over 95 % of BOD5. It has been proven during the certification process that the BusseGT system using microfiltration membranes therefore meets the requirements of the Washington State Legislature Hygienic Standard. The filtrate is fit for re-use without further treatment.
