GOAL, SCOPE AND BACKGROUND One of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle waste water into high quality water. It seems timely to discuss alternative water remediation technologies that are fi...

There is a resurgence of interest in controlling the excessive fertilization (eutrophication) of surface waters in order to protect domestic water supplies and other beneficial uses of waters from impairment (pollution) by excessive growths of algae or other aquatic plants whose growth is stimulated by nitrogen and phosphorus. An area of particular concern is the nutrients added to waterbodies ...

A steam sterilizer (autoclave) was tested to determine the operating parameters that affected sterilization of microbiological waste. Tests involved standardized loads (5, 10 ad 15 lb [ca. 2.27, 4.54, and 6.80 kg, respectively]) contaminated petri plates in autoclave bags placed in polypropylene or stainless steel containers. Thermal and biological data were obtained by using a digital potentio...

The aim of this research is to build a portable system to perform real-time analysis of waste water samples. Thus, that can significantly improve existing waste water treatment technology. In waste water treatment plant, an important parameter, chemical oxygen demand is needed to be measured. The amount of chemical oxygen demand determines the degree of water pollution by organic material. The ...

Urban life has created man-made extreme environments like carwashes. These environments have, however, not been sufficiently explored for mycobiota that can be sources of biotechnologically useful products, as has been the case with natural extreme environments. Using a combination of culture and molecular techniques, fungi from carwash effluents was characterized for production of lipase and c...

Waste from agricultural livestock operations has been a long-standing concern with respect to contamination of water resources, particularly in terms of nutrient pollution. However, the recent growth of concentrated animal feeding operations (CAFOs) presents a greater risk to water quality because of both the increased volume of waste and to contaminants that may be present (e.g., antibiotics a...

During alcohol production, large amounts of waste and wastewater are produced. These may have a considerable environmental impact by polluting both water bodies and soil, by causing an adverse climatic effect and odour nuisance. Due to the high concentration of organic matter, both distillery waste and wastewater at the same time do have a great nutrient and energy potential that can be utilise...

The treatment by ion exchange ol' waste water from comples sulfide hydrometallurgy has Iwen studied. Several commercial resins have been tested for a range of pH in solution. The equilibrium results with an iminodiacetic resin for the multicomponent...

Acrolein may be released to the environment in emissions and effluents from its manufacturing and use facilities, in emissions from combustion processes (including cigarette smoking and combustion of petrochemical fuels), from direct application to water and waste water as a slimicide and aquatic herbicide, as a photooxidation product of various hydrocarbon pollutants found in air (including pr...
