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...

Pharmaceutical drugs play an important role in human life since they caused a revolution in human health. Notably, their administration to a living organism helps body to stay healthy. Commonly, they are employed to diagnose, prevent, or treat and cure a disease via a biological effect on a human body. Administration of impurity-free and adequate amounts of pharmaceut...

The 3M Company incinerates chemical wastes from manufacturing operations in a 23 M kcal/hr (90 MM Btu/hr) rotary kiln incinerator which has air pollution control equipment. This paper deals with the essential features which have resulted in this successful incineration operation for industrial wastes. These features include waste materials handling considerations, design aspects, and main­ tena...

An effort to utilize solid wastes at dumpsite as refuse-derived fuel (RDF) was carried out. The produced RDF briquette was then utilized in the gasification system. These wastes were initially examined for their physical composition and chemical characteristics. The wastes contained high plastic content of 24.6-44.8%, majority in polyethylene plastic bag form. The plastic wastes were purified b...

Industrial wastes may produce leachates that can contaminate the aquatic ecosystem. Toxicity testing in acute and chronic levels is essential to assess environmental risks from the soluble fractions of these wastes, since only chemical analysis may not be adequate to classify the hazard of an industrial waste. In this study, ten samples of solid wastes from textile, metal-mechanic, and pulp and...

this study was conducted to evaluate the effects of different heating treatments (autoclaving, roasting, steam flaking and microwave irradiation) on chemical composition, anti- nutritional compounds (tannin and phenolic), in situ dry mater (dm) and crude prate in (cp) degradability. three fistulated bull in a complete randomized block design and in vitro gas production kinetics (complete random...
