<p>A method of treating waste water is described. Firstly, providing specially acclimatized microbial consortia (18) with relatively low sensitivity to changes in pH and changes in temperature, such that the microbial consortia (18) is capable of metabolizing contaminants (26) efficiently within a predetermined broad pH range and broad temperature range. Secondly, maintain the microbial consortia (18) in a space limited and a substrate limited mode within an immobilized bioreactor (12) operating within the predetermined pH range and the predetermined temperature range. Thirdly, introduce waste water with liquified insoluble organic contaminants (26) into the immobilized bioreactor (12). The organic contaminants (26) are metabolized by the microbial consortia (18) working under space limited and substrate limited conditions, thereby treating the waste water with a minimal sludge production rate. The best mode of waste treatment should include an anaerobic immobilized bioreactor, an anoxic immobilized bioreactor, an aerobic immobilized bioreactor and a nitrification immobilized bioreactor arranged in desired series to accommodate a continuous flow of waste water.</p> |
