Reagent treatment of various types of wastewater
with a three-component composition

Abstract: The results of experimental studies of reagent wastewater treatment with a three-component composition (coagulant, flocculant, alkaline reagent), which were carried out at DalVODGEO LLC (from 2015 to 2018, when one of the authors, S.B. Kundenok, worked as a chief project engineer in this organizations), then jointly with the Far Eastern Federal University (2017–2020). The ratio of reagents in the composition was experimentally selected, and the flocculant is dissolved in soda ash and introduced after the coagulant. Tests on effluents from food production (with a high content of organic and mineral suspended substances), with an insufficient alkaline reserve, confirm the greater efficiency of purification and a smaller volume of sediment in the case of using the composition in comparison, with the separate injection of reagents.

Keywords: waste water, intensification of reagent treatment, coagulum, flocculant, alkalizing reagent, coagulating-flocculating alkaline composition
