In the present study, a successful attempt has been made to develop a simple method for the simultaneous determination of manganese (II) and iron (III) in an industrial effluent using differential pulse polarography (DPP) technique. Quantification of manganese (II) and iron (III) was done in Triethanolamine and KOH as a supporting electrolyte. The polarogram recorded for the industrial effluent...

The treatment of electroplating industrial effluent by coconut husk was carried out by analyzing the physico-chemical parameters of the effluent such as pH, salinity, calcium, magnesium, phosphates, nitrates, BOD3 30C̊ and total solids using standard methods. The efficiency of coconut husk was tested by using it in different quantities such as 25, 50, 75 and 100 grams for five days. As a result,...

In this experimental work the ozone action on the depuration of olive oil mill wastewater is studied for different operational conditions based on an actual industrial treatment plant. It was verified that the application of a Mn-Ce-O catalyst prepared at the laboratory, with a Mn/Ce molar proportion of 70/30, enhances the depuration efficiency and the effluent biodegradability. Ozonation opera...

The process parameters of a reverse osmosis system concentrating industrial wastewater in a closed-loop operation have been studied. The model describes system solute concentration as a function of operating time and can be used to predict separation efficiency and permeate flux. The model uses seven parameters that are obtained from membrane and solution data Simulation of a simple salt system...

In this study, the ultrasonic, photocatalytic and sonophotocatalytic degradation of organics in textile industrial effluent was studied using ZnO nano catalyst, ZnO nano catalyst was synthesized by using sol-gel method. The structure and morphology of the catalyst were investigated using scanning election microscopy (SEM), electron dispersive X-ray spectroscopy (EDS) and X-ray <span id="transma...

Climate change makes people to be aware about the environmental pollutions in aspect of Air, Water and Soil components. The environmentally aware countries have forced the other countries to implement the stringent effluent standards for disposal into water stream / water bodies. Hence, modern technology like the application of membrane separation (Micro or Ultra filtration) technique with biol...

the objectives of this investigation are the studies on the effect of copper ion on photolytic degradation of ethylenediaminetertraaceticacid (edta), the effect of edta on electrolytic recovery of copper as well as the introduction of a novel combined photolytic and electrolytic cell system for simultaneous recovery of copper and the degradation of edta.in this experimental study, a photolytic ...

Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical are used for the treatment of industrial effluent. The commonly used conventional biological treatment processes are time consuming, need large operational area and are not effective for effluent containing toxic elements. Advanced oxidation techniques result in high treatment cost and are generall...

Worldwide, wild fish living in rivers receiving municipal and industrial discharges may experience endocrine disruption as a result of exposure to anthropogenic pollutants. The purpose of this study was to evaluate the hormonal status of wild fish in a U.S. river receiving unbleached kraft and recycled pulp mill effluent (Pearl River at Bogalusa, LA). We evaluated two alternative hypotheses: th...

The effect of indigo dye effluent on the freshwater microalga Scenedesmus quadricauda ABU12 was investigated under controlled laboratory conditions. The microalga was exposed to different concentrations of the effluent obtained by diluting the dye effluent from 100 to 175 times in bold basal medium (BBM). The growth rate of the microalga decreased as indigo dye effluent concentration increased ...
