Most of the world’s water is saline and is contained in the oceans. Only about 2% of it is fresh of which 97% is tied up in the polar caps in the form of permanent snow and in deep depths below the ground. Scarcity of potable water for the construction is the main reason to look for alternate source of water. Industrial waste water is potential alternate for construction industry. Recycling and...

The separation (or removal) of organic residues from aqueous waste streams released from industries is important and essential from the points of view of pollution control and recovery of useful materials. The disposal of waste waters containing most widely-used industrial organic acids such as acetic acid, formic acid and propionic acid has been recognized as a significant expense to the indus...

Efficient waste paper recycling has a significant role in the sustainable environment. Recyclable waste paper as a fundamental ingredient of municipal solid wastes (MSWs) is indeed an ‘‘urban ore’’. Waste papers are considered as the solid recovered fuel which is recovered from MSW. Recyclable waste papers are segregated into various grades to produce high-quality products. Moreover, sorted pap...

Textile industries have their own importance in Indian economy. It consumes large amount of water and as a result huge amount of waste water is generated. Textile effluent comprises of suspended solids, mineral oils, residual oils and is characterized by high BOD (from 700 to 2000 mg/l) and COD loads. It is necessary to treat the waste water so that it does not have any threat to the environmen...

Sulfides are particularly problematic in the sewage industry. Hydrogen sulfide causes corrosion of concrete infrastructure, is dangerous at high concentrations and is foul smelling at low concentrations. Despite the importance of sulfide monitoring there is no commercially available system to quantify sulfide in waste water. In this article we report on our use of an in situ spectrometer to qua...

Olive mill waste water is the major byproduct of the olive oil industry containing a range of compounds related to Olea europaea and olive oil constituents. Olive mill waste water comprises an important environmental problem in olive oil producing countries, but it is also a valuable material for the isolation of high added value compounds. In this study, an attempt to investigate the secoirido...

Electroless plating is a chemical reduction process which depends upon the catalytic reduction of a metallic ion in an aqueous solution containing a reducing agent without the use of electricity (1). Cahill (2) showed that the cupric ion could be reduced autocatalytically with formaldehyde in an alkaline solution. Okinaka (3 ) established that the overall reaction of the catalytic copper platin...

the textile industry has long been one of the largest of water users and nolluters and there has been little success in developing low cost treatment methods , which the industry urgently needs to lessen the pollution loads it discharges to streams. the obiective of this preparatory study was to determinen the effects o f coagulants and aid coagulant s as alum, ferrous sulfate , ferric sulfate ...

This paper represents the results of ten pollution prevention/waste minimization assessments performed on marine maintenance and commercial printing industries in the Hampton Roads area of the Commonwealth of Virginia. The pollution prevention project is the result of a working partnership (the Partnership) formed between Old Dominion University Department of Civil and Environmental Engineering...
