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 ...

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...

Mijangos, F. and Diaz, M., 1990. Ion exchange recovery of metals from waste water of complex sulfide hydrometallurgy. Hydrometallurgy. 23: 365-375. 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...

Waste materials are common problem in modern living. Waste accumulates from number of sources including domestic, industrial, commercial, construction and demolition activity. A significant portion of municipality waste is construction related. Proper management of construction and demolition waste is important or else it will get mixed with municipal waste. This type of mixing leads to cutting...

Our knowledge base regarding the presence and significance of chemicals foreign to the subsurface environment is large and growing—the papers in this volume serving as testament. However, complex questions with few answers surround the unknowns regarding the potential for environmental or human health effects from trace levels of xenobiotics in ground water, especially ground water augmented wi...

The textile industry represents a range of industries with operations and processes as diverse as its products. Textile industry effluents account for several point sources of water pollution thus posing negative effects on aquatic lives and human health. The paper contains results of a study carried out in agricultural fields of Sanganer town. This paper contains results of physico-chemical an...
