Cryptosporidium and Giardia

摘要

Toxicants in wastewater treatment plant influent may inhibit the biological activity of the activated sludge and upset the plant process. This can be avoided if influent wastewater is monitored for toxicity and protective action is taken when toxicity is detected.rnThe BAROXYMETER from TCS Bioscience (UK) is a portable respirometer designed for the Direct Toxicity Assessment (DTA) of waste water. DTA takes a risk-based approach to water quality analysis, using effects in biological systems as a basis for assessing likely harm to an ecosystem in water receiving effluent discharges.
