  • Method and apparatus for the purification and/or treatment of commercial and/or industrial waste waters
    Patent number: 6290852
    Abstract: In a method and apparatus for the purification and/or treatment of communal and/or industrial wastewaters, particularly for use in marine installations, a biologically operated reaction apparatus is provided in which the wastewater to be purified and/or treated is received. In the reaction apparatus, a bio-mass of high concentration is suspended. To this reaction apparatus, the wastewater to be purified and/or treated is supplied. Subsequently, the pre-purified or, respectively, pre-treated wastewater is supplied to a membrane separation apparatus in which it is separated into a permeate and a retentate. The retentate is at least partially returned to the reaction apparatus, whereas the permeate is either discharged as useable or pure water or is returned to the reaction apparatus.
