Paper Details

In the past decades, several models have been developed to describe nutrient removal from wastewater.Most of these models are based on activated sludge systems or photosynthetic organisms, such as algae and plants,which are known to be efficient in nutrients uptake. However, there is a lack of models describing the interactions incombined algal-bacterial systems. This research proposes a model to describe the nutrient removal processes in treatingwastewater with an algal-bacterial consortium. “Pollution control is one of the most important factors in preserving abalanced environment”. There are many methods of removing pollution from municipal wastes, ranging from simplemunicipal primary treatment, to complex biological and chemical primary or secondary or tertiary treatment. All thesesystems are primarily concentrated on removal of bio logical oxygen demand (BOD) wastes. Even presence of the highammonical nitrogen, heavy metals like hexavalent chromium, arsenic, nickel, mercury etc. will create problem insecondary treatment. In another manner of expression, the invention concerns a method of pollution control whereinunicellular or we can say similar algae, such algae being a good source of protein, are grown in symbiotic relationshipwith aerobic bacteria on nitrogen-providing or protein-providing aqueous waste materials such as portions of sewage,cannery wastes, etc., in a way that produces purified water, an algal mass high in protein, and free oxygen, which isliberated to the atmosphere.
