Description

[0001] technical field of invention

[0002] The present invention relates to a method for purifying wastewater in a biological manner, bacteria and mixed bacterial populations suitable for the method and uses thereof. The invention still further relates to a bioreactor comprising said bacteria or mixed population. Background of the invention

[0003] Usually water is purified by physical and chemical methods, eg by sedimentation, filtration or flocculation (WO94 / 5866 and WO88 / 5334). For the removal of organic compounds and other compounds which are difficult to purify, so-called biological purification methods are also preferably used, ie the waste water to be purified is brought into contact with microorganisms which degrade the pollutants. The biological water treatment method is suitable for common water treatment plants and industrial wastewater treatment plants. Biological water treatment has been tested for water recirculation systems (FI 964141). Biological water tr...
