Abstract

Experience of Suckling Perfection of Secondary Clarifier of Aeration Station in Almaty, Kazakhstan

Highlights

The treatment of sewage water in the cities of Kazakhstan is mainly performed by using biological aeration tanks with secondary clarifier
The efficiency of biological wastewater treatment is determined by the work of secondary settling tanks, which should ensure the allocation of the activated sludge from the purified water
The intensity of the sludge on the growth of cells is regulated by several factors and depends on: the nature of the oxidized substrate; the temperature of treated wastewater, which determines the degree of the assimilation processes; self-oxidizing capacity of the activated sludge, depending on the load and the period of aeration on structures; sedimentation characteristics of the sludge and the removal of suspended solids from the secondary clarifiers; the presence of toxicants or mutagens-growth stimulants [Al-Bastaki 2004, Hunze 2005, Pijuan et al 2012]
