Experimental Study on Pretreating Dairy Farming Wastewater by Adsorption-Filtration Method

Adsorption and Biological Filtration in Wastewater Treatment

Feasibility Study of Vermi-filtration for the Treatment of Dairy Wastewater

The wastewater generated in dairy industry contains very high organic loading and total solids and is mostly treated in ETP (Effluent Treatment Plant ), where the sludge is formed increasing the expenditure for processing and disposal along with the operation cost. Earthworms body act as a ‘biofilter’ and they were found to increase the removal efficiency of BOD3 – 89.3 %, 86.5 %, 91.6 %, COD –...

Feasibility Study on the Production of Biogas in Dairy Farming

The purpose of this study was to evaluate feasibility study on the development of biogas in dairy farming. In short of the production process, the biogas was produced by utilizing waste from dairy farming industry (i.e. cow’s manure and cassava peel). The production of biogas was analyzed from engineering perspective with several economic evaluation parameters, including gross profit margin, in...

Experimental Study and Adsorption Modeling of COD Reduction by Activated Carbon for Wastewater Treatment of Oil Refinery

Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reductio...

Urban wastewater disinfection by filtration technologies

The microbiological quality of effluents from different macrofiltration systems (pressure sand filter and disc filter) used as pre-treatment and membrane technologies (microfiltration and ultrafiltration) was evaluated in order to determine their possible application as alternatives to disinfection of urban wastewater prior to reutilization. Microbiological quality was determined by reference t...
