Adsorption Combined Phytoremediation System for Treatment of Laundry Wastewater

Combined Anaerobic-aerobic System for Treatment of Textile Wastewater

Textile manufacturing consumes a considerable amount of water in its manufacturing processes. The water is primarily utilized in the dyeing and finishing operations of the textile establishments. Considering both the volume generated and the effluent composition, the textile industry wastewater is rated as the most polluting among all industrial sectors. In this study a combined anaerobic-aerob...

Hybrid Adsorption and Biological Treatment System (HABiTS) for enhanced nitrogen removal in onsite wastewater treatment systems

A Hybrid Adsorption and Biological Treatment System (HABiTS) was investigated for efficient nitrification in on-site wastewater treatment. Variable septic tank effluent loading experiments were carried out in bench-scale columns, with and without zeolite addition. Enhanced NH4-N removal (80%) was observed in the HABiTS column that combined expanded clay and clinoptilolite compared with a contro...

Improvement of Nanosized CuO-Fe2O3/cordierite System by Li2O-treatment for wastewater treatment

A mixture of 10 wt% CuO-10 wt% Fe2O3 supported on cordierite were prepared by wet impregnation. The as-prepared solids doped with Li2O (0.75-3 mol %) were calcined at 500-900 ºC. The crystalline phase, morphology, and surface area were investigated by XRD, HR-TEM and N2-adsoprtion-desorption. Moreover, their photocatalytic activities of samples calcined at 700°C on the degradation of phenol wer...

Adsorption and Biological Filtration in Wastewater Treatment

Chemical Industry Wastewater Treatment Using Adsorption

In a typical wastewater treatment fl ow sheet used by several industrial units in Indi a. various stages of treatment include primary treatment. foll owed by secondary treatment . and tertiary treatment. The concentration of total dissolved solids increases during neutrali zation of the wastewater with acid/ alkali during primary treatment. which adversely affects the activity of microorgani sm...
