Anaerobic Co-digestion of Wastewater Treatment Pond Algae with Wastewater Sludge
<p>Microalgae harvested from wastewater treatment ponds can be anaerobically digested to produce biogas, a renewable fuel resource. However, past experiments have shown some limitations of algae digestion. Algal cell walls are thought to be resistant to digestion, and the high protein content of …

Electrodisinfection of Municipal Wastewater Effluent
To avoid the spread of disease from sewage treatment effluents, pathogenic microorganisms present must be destroyed by one or a combination of disinfection methods. Chlorine remains the predominant disinfectant used although it consumes considerable amounts of energy and has associated exposure …

Wastewater Treatment of Contaminated Aqueous Leachate
Until recently the common perception, especially in the western world, was that water was an infinite resource. There has been, however, a dramatic increase in the usage and pollution of water and a corresponding need to conserve, treat and re-use the resource. Water quality and scarcity are major …

Odor Monitoring at Wastewater Treatment Plants
… corrosion is one of the major sources of odor in wastewater treatment plants. Evaluation of existing or potential odor problems requires knowledge of the type of compounds likely to cause such problems and the mechanism of their formation in wastewater systems which is discussed in this paper. For …

Development of nitroguanidine wastewater treatment technologies
… a method for treating nitroguanidine process wastewaters. The major wastewater contaminants were found to be nitroguanidine and guanidine nitrate (GN) (an intermediate product). Pilot tests were conducted for the removal of nitroguanidine using granulated carbon adsorption (GAC) and ion …

Local marine wastewater discharges : characterisation and impacts
Raw municipal wastewaters from the three major sewage pumping stations in the Maltese Islands were sampled three times daily over a 7-day period in August-September 2002 so as to identify levels of suspended matter, nutrients (nitrates, nitrites, orthophosphates and total phosphorus), and …
