Common effluent treatment plants

Anti-androgens entering the aquatic environment, e.g., by effluents from wastewater treatment plants or agricultural settings are contributing to endocrine disruption in wildlife and humans. Due to the simultaneous presence of agonistic compounds, common in vitro bioassays can underestimate the risk posed by androgen antagonists.

The present study was envisaged to check the physico-chemical properties of effluents being treated at CETPs and to isolate indigenous heavy metal tolerant bacteria for their subsequent utilization for heavy metal uptake. Effluent samples were collected from two CETPs located in Ludhiana and Jalandhar and were analyzed for their physico-chemical parameters (dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD) and pH) and heavy metal profile using Inductively Coupled Argon Plasma-Emission Spectroscopy (ICAP-AES).

A field experiment was conducted at the Common Effluent Treatment Plant (CETP), Dindigul, Tamil Nadu during kharif season to study the irrigation management through wastewater recycling on growth parameters of cotton. Field experiment was laid out in factorial randomized block design with four replications.

The present study was envisaged with the objective to isolate indigenous chromate tolerant bacteria from effluents and their subsequent utilization for chromium uptake or reduction. Samples were collected from two different Common Effluent Treatment Plants (CETPs), located in Ludhiana (sample 1) and Jalandhar (sample 2). In both the samples, chromium was found to be the dominant metal contaminant. A total of 10 morphologically distinct isolates were tested for their tolerance to chromium in terms of minimum inhibitory concentration (MIC) of Cr required for complete inhibition of growth.

The performance of a vertical subsurface flow constructed wetland (VSSFCW) for sewage effluent treatment was studied in an eight month experiment under different operational conditions including: vegetation (the presence or absence of common reeds ‘‘Phragmites australis”), media type (gravel or vermiculite), and mode of sewage feeding (continuous or batch). Plants had a significant effect (P < 0.05) on the removal efficiency and mass removal rate of all pollutants, except phosphorous.
