The effluent treatment plant sludge is one of the major sources of contamination with toxic metals. Since the sludge contains heavy metals, it must be pretreated to reduce the contamination. The heavy metals from the sludge can be reduced/ separated by washing it with a suitable leaching solution. In the present study, the efficiencies of three leaching solutions to remove the contaminants from...

A marine photosynthetic bacterium (PS88) identified as Rhodovulum sp. with flocculating ability was isolated from the sea sediment mud of a shrimp cultivation farm in Thailand. This bacterium flocculated in glutamate/malate medium during aerobic/dark or anaerobic/light cultivation. The flocculating ability was enhanced with the increase of NaCl concentration to 6% (w/v). Flocculation and growth...

Colloidal dispersions in nonpolar media are used in a variety of technological applications, and in most of these applications, water is present and plays a major role in determining the dispersion behavior. The effect of water on the stability of colloidal suspensions of alumina in cyclohexane in the presence of a surfactant, Aerosol OT, is discussed here. A succession of flocculated, disperse...

The UASB Reactor concept represents a very promising proposition for the anaerobic treatment of a variety of industrial wastes and even of domestic wastes. In the present study, after careful acclimatization, the granules were found to be well adapted to fish processing effluent and the COD reduction was upto 96% at organic loading rates from 150 mg l–1 d–1 to 2,200 mg l–1 d-1. The biogas produ...

background sewage sludge (biosolids) is a byproduct of wastewater treatment that accumulates in large quantities. effective stabilization and disinfection of sewage sludge prior to land application are necessary to not only protect human health, but also to induce the public its benefits and safety. currently, many wastewater treatment plants in iran dispose great amounts of untreated sewage sl...
