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.
