Decolorization of dye wastewaters by biosorbents: a review.

Dye wastewater is one of the most difficult to treat. There has been exhaustive research on biosorption of dye wastewater. It is evolving as an attractive option to supplement conventional treatment processes.

Oil removal from water using biomaterials.

A batch study was conducted to evaluate efficiencies of four types of biomaterials to remove oil from water. The oils used in the study were standard mineral oil, vegetable oil and cutting oil. Two fungal biomasses of Mucor rouxii and Absidia coerulea along with chitosan and walnut shell media were the biomaterials used.

Oil removal from water by fungal biomass: a factorial design analysis.

A fractional factorial design analysis was conducted to screen the significant factors influencing removal of three emulsified oils from water, namely, standard mineral oil (SMO), canola oil (CO) and Bright-Edge 80 cutting oil using non-viable biomass of fungus Mucor rouxii rich with chitosan in its cell wall. Factors investigated were pH of the solution (3-9), temperature (5-30 degrees C), adsorbent dose (0.05-0.

Biological treatment processes for fish processing wastewater--a review.

Water consumption in a fish-processing industry and high-strength wastewater from such an industry are of great concern world-wide. Liquid effluent regulations are becoming more stringent day by day. Biological treatment is the best option for such a wastewater.

Perchlorate: health effects and technologies for its removal from water resources.

Perchlorate has been found in drinking water and surface waters in the United States and Canada. It is primarily associated with release from defense and military operations. Natural sources include certain fertilizers and potash ores.
