Aeration for increasing the bioactivators efficiency in treating household wastewater containing synthetic detergents

Abstract

The paper presents the research results of synthetic detergents influence on various bioactivators efficiency in household wastewater treatment. The research has been carried out using model solutions simulating domestic wastewater, where organic pollutants were represented by the solutions of sucrose, starch and milk powder, and synthetic detergent was used as toxicant-pollutant. The bioactivators effectiveness in the presence of synthetic detergent in model solutions treatment was assessed according to the changes of chemical oxygen consumption during static experimental studies. The study shows that bioactivators effectiveness in the treatment of household waste water containing synthetic detergents increases from 7 to 31% when aeration is applied. The recommendations are given for the considered bioactivators application in household waste water treatment under various operating conditions.
