How it works

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 pretreatment step, which also serves as waste water storeage, biologically degradable coarse material such as, e.g., faeces, 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 0.4 µm pore size). These membrane filters eliminate suspended material, as well as bacteria and germs, ensuring that only totally clear, odourless, hygienically harmless water (filtrate) leaves the system.

The Busse MF system has been tested successfully by the Institute PIA in Aachen according to the new European standard and the filtrate from the system in normal service is significantly better than the limits set by DIBt Berlin and the applicable laws. Due to the immersed microfiltration membranes, in combination with a technologically requiring high concentration of biomass, the COD level in the discharged water can be reduced to under 30 mg/l* and the BOD5 value to under 5 mg/l*.
