Can trade effluent charges promote compliance and address water security risks in Nairobi’s manufacturing industries?
This research assessed whether trade effluent charges could promote compliance and address water security risks in manufacturing industries in Nairobi. This is due to the burden of effluent management that Nairobi City Water and Sewerage Company (NCWSC), the largest water supply and sewerage …

The Effects of a Paper Mill discharge on the Benthic Macro- Invertebrates of the River Llynfi
The effects of a kraft paper mill effluent discharge on the benthic invertebrates in the Rivers Llynfi and Ogmore were determined by regular collection of biological samples from six sites. One site was upstream of the effluent discharge, two downstream on the Llynfi, one on the Ogmore before the …

The effect of treated wastewater effluent on the water quality of the Natalspruit river
… (herein referred to as Plant A, B, and C) that discharge effluent into the Natalspruit river. Historical data for a period of three years from 2016 to 2018 was used to determine the potential threat posed by effluent discharge to the river water quality. The three years data was adequate to see …

Characterization, utilization and treatment of mechanized clam processing wastes
… quality deterioration caused by clam processing effluent, the Virginia State Water Control Board is imposing much greater effluent discharge limitations on the industry. Meeting these limits will require increased wastewater treatment and decreasing the water volume of water used and the loading …
