Contamination types, levels and their behavior within drilling wastes is determined by the local geological conditions and drilling mud design; notably lubrication fluids, weighting agents and anti-foaming agents. Such additives can contain potentially toxic elements such as aluminum and barium. Besides being contaminated, drilling wastes often have a high pH due to the addition of lime, causti...

hospital wastewater has special importance since having pathogens, radioactive materials, pharmaceutical wastes and heavy metals. removing them into environment without any treatment may cause serious problems for the public health. membrane biological reactor is the combination of the activated sludge and membrane filters. this research has investigated the performance of the nano-filtration i...

The Resource Consumption and Recovery Act (RCRA), 1976, encourages waste minimization via practices like source reduction and solvent recycle. Waste streams treated with the orthodox end-of-pipe treatment options like thermal incineration, chemical oxidation etc. has to be reported as RCRA hazardous. To avoid strict environmental regulations imposed on all such effluent streams, this paper expl...
