Two bacterial strains were isolated from pharmaceutical effluents discharged soil. The samples were identified as Klebsiella pneumonia and Pseudomonas aeruginosa the biological degradation was carried on two bacterial isolates separately added to pharmaceutical effluent water. After proper interval were analysed the physic chemical parameters such as pH, Turbidity, Chemical oxygen demand (COD),...

Nitrogen and phosphorus present in sewage can be used for microalgae growth, possibiliting cost reduction in the production of microalgae at the same time that it decreases the eutrophication potential of the effluent. This research aimed at monitoring the native community of microalgae and coliform bacteria in a secondary effluent from anaerobic municipal sewage treatment. Two treatments (aera...

A study of the response of the polychaete community associated with the rocky mussel beds to a sewage discharge was carried out in the area of Eforie Sud during summer 2005 and summer 2006. Three stations and a control site were randomly sampled around the Eforie Sud effluent. In each station water quality variables were also measured. A total of 15 species were encountered. The most impacted s...

Pilot-scale struvite crystallization tests using anaerobic effluent from potato processing industries were performed at three different plants. Two plants (P1 & P2) showed high phosphate removal efficiencies, 89+/-3% and 75+/-8%, resulting in final effluent levels of 12+/-3 mg PO(4)(3-)-PL(-1) and 11+/-3mg PO(4)(3-)-PL(-1), respectively. In contrast, poor phosphate removal (19+/-8%) was obtaine...

The phosphorus and nitrogen discharge via effluent of intensive trout farming system was quantified through the use of environmental indicators. The nutrient loads, the mass balance, the estimated amount of nutrients in feed and the amount of nutrients converted in fish biomass were calculated based on the concentrations of phosphorus (P) and nitrogen (N) in the feed and in the water. Of the of...

AquaFuture operates a 1.8 million gallon recirculating aquaculture facility capable of filtering the waste products from over three quarters of a million fish that are fed over one million pounds of feed per year. This paper describes a compact system for effluent treatment and residuals management that has proven effective at maintaining water quality within compliance limitations. Solids are ...
