Toxicity Studies of Treated Residual Wastes in Austria using Different Types of Conventional Assays and Cost-Effective Microbiotests

Abstract : The toxicity and chemical quality of 12 mechanically-biologically treated residual wastes were studied during different treatment periods. Acute and chronic bioassays were carried out with a battery of test organisms. The acute toxicity was assessed using Daphnia magna (crustacea) and Vibrio fischeri (luminescent bacteria). The chronic toxicity was tested with Selenastrum capricornutum ...

Ecotoxicology and Water Quality Standards

Abstract : The establishment of water quality objectives (WQO) for individual chemicals is a complex process fraught with many uncertainties. WQO should (in principle) be derived from ...

‘Poor gain’ from extra treatment of wastewater to remove pharmaceuticals

A recent study compared the decentralised treatment of pharmaceutical contaminants in wastewater at hospitals with centralised treatment at conventional and upgraded wastewater plants. The results suggest that additional (post) treatments may not ...

Coated Waste Water Storage Tanks with Corrosion Resistance

Wastewater storage tanks is a kind of common wastewater treatment equipment in the field of wastewater treatment. There are many kinds of complicated corrosion forms in wastewater, such as acid-base corrosion, atmospheric corrosion, abrasion, penetration type expansion crack and microbial corrosion of bacteria and algae, which seriously affect the service life of wastewater treatment tank. ...
