Microbiological investigations on nitrite-accumulation in wastewaterstorage - reservoirs

Wastewater storage reservoirs in Israel are frequently affected by the unwanted accumulation of high quantities of nitrites. This is caused by various factors, such as insolation, increased concentrations of ammonia and the bioavailability of iron. Investigations have shown that this problem can be solved by an increase in the active mass of nitrifying bacteria associated with the provision of darkened cultivation zones.
