Predicting the amount of water that may seep into waste emplacement tunnels (drifts) is important for assessing the performance of the proposed geologic repository for highlevel radioactive waste at Yucca Mountain, Nevada. The repository will be located in thick, partially saturated fractured tuff that—for the first several hundred years after emplacement— will be heated to above-boiling temper...

Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatmen...

Huge amounts of waste biosolids are produced from biological processes as waste water treatment, agriculture and food production. The volatile compounds could be utilised as a source for renewable energy in anaerobic processes. However, the anaerobic degradation is slow so that large fermenters are necessary. By ultrasonic disintegration the rate limiting hydrolysis of volatile solids is substi...

The disposal of industri al eftluents is a problem of increasing importance throughout the world. In Indi a, a huge amount of waste water generated from distillery and paper industri es is discharged on land or into the running water. Di stillery waste water is characterized by low pH, hi gh BOD and COD values and contains a high percentage of organic and inorganic material s. This waste water ...

Salty food waste is difficult to manage with previous methods such as composting, anaerobic digestion, and incineration, due to the hindrance of salt and the additional burden to handle high concentrations of organic wastewater produced when raw materials are cleaned. This study presents a possibility of recycling food waste as fuel without the burden of treatment washing with water by pyrolyzi...

firehouse, technical assistance could be solicited. For example, the county supervisor of the Farmers Home Administration might be called in to discuss that agency's requirements regarding financing for public water and waste disposal facilities. Farmers Home is authorized to provide financial assistance to rural "associations" for the purpose of installing community domestic water and waste sy...

Pharmaceutical industry represents a range of industries with operation and processes as diverse as its product. Hence effluents coming from pharma industries vary from industry to industry. Thus it is almost impossible to describe a typical pharmaceutical effluent because of such diversity. Waste water is generally evaluated in terms of temp, pH, Total suspended solid (TSS), BOD, COD, Oil & gr...

This investigation was undertaken to determine the relative effects of recommended land spraying while drilling (LWD) loading rate application for a source of water-based drilling waste material on selected soil properties and phytotoxicity. Drilling waste material was obtained from a well where a nitrate gypsum water based product was used to formulate the drilling fluid. The fluid and associa...

A preliminary study, which establishes the treatment methodology of liquid waste containing sludge and uranium in the lagoon of the conversion facility has been performed. Properties of the liquid waste such as initial water content, density and radiochemical composition were obtained by analyzing the samples taken from the lagoon. In order to minimize the secondary waste resulting from treatme...

In this paper comprehensive studies have been carried out for the design optimization of a waste heat recovery system for effectively utilizing the domestic air conditioner heat energy for Keywords—Air-conditioning system, Energy conversion system, Hot water production from waste heat, Waste heat recovery system.
