Among the current pollutants in our water bodies, one that has greatest degree of pollution and impact on environment is heavy metal wastewater. Various ions bodies can seriously disrupt ecological balance spread throughout biosphere through natural material cycle other means. Excess not only endanger health aquatic organisms, but also enrich animals even humans, posing a serious threat to huma...

The wastewater generated from pharmaceutical industry generally contain high organic load and the treatment is primarily carried out using two major types of biological methods; aerobic and anaerobic. However, due to high strength, it is infeasible to treat some pharmaceutical wastewater using aerobic biological processes. As an alternative, an anaerobic process is preferred to remove high stre...

In the future, energy prices are expected to rise as the demand for energy reso...

In recent years, membrane technology has been widely used in wastewater treatment and water purification. Membrane technology is simple to operate and produces very high quality water for human consumption and industrial purposes. One of the promising technologies for water and wastewater treatment is the application of forward osmosis. Essentially, forward osmosis is a process in which water i...

Focus The Wastewater Management Program includes wastewater collection and conveyance, wastewater treatment, and planning and monitoring program a...

A bioflocculant-producing bacterium, Bacillus megaterium SP1, was isolated from biofloc in pond water and identified by using both 16S rDNA sequencing analysis and a Biolog GEN III MicroStation System. The optimal carbon and nitrogen sources for Bacillus megaterium SP1 were 20 g L-1 of glucose and 0.5 g L-1 of beef extract at 30°C and pH 7. The bioflocculant produced by strain SP1 under optimal...
