Ecotoxicological Investigations in Effluent-Dominated Stream Mesocosms
… was designed to examine contaminant impacts on effluent-dominated stream ecosystems. Stream mesocosms, fed municipal effluent from the City of Denton, TX, Pecan Creek Water Reclamation Plant (PCWRP), were treated with 0, 15 or 140 µg/L cadmium for a 10-day study in August 2000. Laboratory …

Cultivation of microalgae on fishery effluent in industrial environment
Eftir mikinn vöxt á síðustu árum stendur fiskeldi nú frami fyrir því að auðlindir geti orðið takmarkandi fyrir frekari vöxt - viltur fiskur sem notaður er í fóður er ekki óendanleg auðlind. Plöntufóður ræktað á landi gæti komið í stað fisks, en það hefur þó sína ókosti s.s. samkeppni um land við …

Combined anaerobic-aerobic treatment of a simulated textile effluent
This work aimed to treat a simulated textile effluent (STE) with combined anaerobic aerobic treatment. A simple simulated cotton processing effluent was generated that was similar to real effluents in terms of COD, BOD, COD:BOD, pH and TSS. An upflow anaerobic sludge blanket reactor (UASB) was …

Use of treated effluent water in cellulosic ethanol production
… was to examine the use of treated wastewater effluent in place of potable freshwater for cellulosic ethanol production. The effects of using two different types of filtered treated effluent; Bloomington- Normal, IL (Residential type) and Decatur, IL (Industrial/Residential Mix type); on the …

Effluent analysis of model pyrrone compounds by gas chromatography
… study was made to quantitatively analyze the effluents produced during the thermal cyclization of several polyimidazopyrrolone (pyrrone) model compounds. The study yielded information on analogous polymeric reactions. The model compounds were programed at 5° C/min from 25° to 400° C and …

Hydrodynamic cavitation for effluent treatment: using vortex-based cavitation devices
… application of hydrodynamic cavitation for effluent treatment is investigated. Despite the promise, hydrodynamic cavitation based effluent treatment is limited in industrial practice. This could be due to problems arising from the use of conventional - linear flow devices, namely venturi …

Microwave assisted remediation of organic waste in aqueous effluent streams
… with contaminated organic waste in aqueous effluent. During the PUIREX process operated by British nuclear Fuels Ltd, the recovery of radioisotopes using 30% tributyl phosphate in odourless kerosene, the organic phase is degraded due to the effects of radiolysis. This results in a very …

Activated sludge process : effects of feed concentration on effluent COD
… was found to exert a significant effect upon its effluent COD. A mathematical model was proposed to explain this effect and was successful in correlating the data of this study. The model was based on the hypothesis that COD measures both substrate and product concentrations. It was found that an …
