activated sludge

The issues of rational use of natural resources, ecological safety and environmental protection are extremely urgent and require immediate human influence on the optimization of technological processes, reducing the impact on the ecosystem. The implementation of food industry technology is accompanied by the formation of a significant amount of wastewater, into which about a third of processed raw materials go, and the concentration of polluting components in them is 10...100 times higher than in household water.

At present, mechanical, chemical, biochemical and physicochemical methods of cleaning are developed and efficiently used to protect water bodies from sewage pollution. The methods of biochemical wastewater purification from organic contaminants with the use of activated sludge have received the highest recognition. Getting of additional nutrients (nitrogen, phosphorus, potassium) and other trophic precursors into the aquatic ecosystem directly leads to immediate biohydrogenase reaction of increase in the number and biomass of the primary producers of organic matter.
