Monitoring of parasitological contamination in treated wastewater from activated sludge system
Abstract
Purpose
The goal of this paper is to detect helminth eggs in treated wastewater for sanitary control, using them as biological indicators of wastewater quality.
Design/methodology/approach
Samples were taken from the Municipal Wastewater Treatment Plant of the Metropolitan Area. To concentrate the samples, centrifugation‐flotation on 33 percent zinc sulphate was applied.
Findings
The study revealed the constant presence of helminth eggs as Ascaris sp., Enterobius sp., Hymenolepis sp., and Strongyloides sp.
Originality/value
The results indicate that helminth eggs can be used as bioindicators for sanitary control of treated wastewater to be reused in urban areas.
