One of the urgent issues for the regions of Kazakhstan is the rational use of water resources.
In particular, the biocenosis of activated sludge from urban wastewater treatment plants periodically encounters stressful situations related to equipment malfunction or emergency discharge of toxic substances into the wastewater treatment plant system. It has been established that with sharp fluctuations in the physico-chemical parameters of aqueous solutions, protozoa are primarily destroyed from the composition of activated sludge. This pattern was observed with increasing fluctuations in ammonium nitrogen, phosphorus, monoethanolamine, and pH in wastewater. In Western Kazakhstan, it was found that in the 10-month period of active insolation in the wastewater treatment complex of the city of Zhanaozen, Mangystau region, the species diversity of active algae is associated with the length of daylight hours, as well as in the autumn and winter period, diatoms predominate, and in spring and summer, blue-green and green algae.
