Pollution of the waterways is a great challenge of the 21st century. Textile effluents contain compounds which have the capacity to cause more harm when ingested. There are many dye removal technologies like coagulation, photo oxidation which help to remove color from dye wastewater. The use of adsorption to remove color from dye wastewater has been used for many centuries. Activated carbon can efficiently remove color from dye wastewater but it is very expensive and so different researches have been conducted to get the adsorption capacity of different forms of adsorbents. These adsorbents can be gotten from agricultural waste, biomass, …

Dairy industry is one of the major industries from which organic wastewater is produced and released into the water bodies. Textile industries also generate considerable amount of dye wastewater that effect the water quality standards. Various treatment techniques are adopted to treat the wastewater. Adsorption is one of the low-cost treatment processes to treat the textile and milk wastewater. This thesis focuses on the treatment of combined dye and milk wastewater using the process of adsorption. The treatment process is carried out by using three different types of low cost adsorbents Peanut-hull, Banana peel and Activated carbon. The effectiveness of …

The release of dye waste water into environment causes harm to aquatic life when they reach drains or other water sources. They pollute the soil and causes change in cycles of plant and animal life through bio-accumulation and nutrient cycle. Dyes which form residue or precipitate causes mutations or changes in the DNA of living organisms in and around the area of release of the dye into atmosphere. In this thesis, several runs were attempted to treat the synthetically prepared dye waste water using dehydrated peanut hull. The initial dye waste water samples were all collected and checked for absorbance, …

Modeling water quality has been shown to be a useful tool in strategizing water quality management. Dissolved oxygen (DO) has one of the largest impacts on water quality compared to other parameters. The purpose of the dissertation research is to generate a regression equation model, using the US EPA QUAL2K model as the base, to determine different factors affecting minimum dissolved oxygen concentrations in streams, to determine the critical distance for the minimum dissolved oxygen concentration, and the magnitude of impact of each parameter. Based on regression analysis, the factors affecting minimum DO in river water are effluent biochemical oxygen …

Wastewater from coffee processing industry creates high biological and chemical oxygen demand in the surface water. In addition to coffee wastewater from coffee industry, dyes from textile industry enter surface water affecting water quality in terms of transmissivity of light. Adsorption is an economical wastewater treatment process to remove color from dye and coffee wastewater. In the current thesis, adsorption using low-cost adsorbents like peanut hull and onion peel are used to treat combined dye and coffee wastewater. Three representative dyes including acid black 48, disperse yellow 3, crystal violet certified with processed coffee is used in preparing batch adsorption …
