were the weakness in industrial wastewater management and the lack of civic awareness. The weakness in industrial wastewater management was the main cause of water pollution in Vietnam. Many industrial facilities used freshwater to carry away waste from their plants into canals‚ rivers‚ and lakes. Most of the enterprises did not have any wastewater treatment system and many industrial zones did not have a central wastewater treatment plant. Industrial wastewater was directly discharged into

As of recent times peri-urban communities cannot rely on this system due to uncertainty of the water in the source. As an alternative source farmers are using wastewater from Hanumante River from years. Yet‚ the dependency on wastewater from the Hanumante River is increasing annually with increasing unreliability of water quantity from the Raj Kulo. The peri-urban communities have developed their own way to cope up with the situation. Farmers constructed

The stabilization ponds have not been expanded since the inception of the university despite the ever rising population of students and staff. As such this study was set to evaluate the efficiency of the wastewater stabilization ponds in wastewater restoration by the use of bioindicators.

Effect of Iodine on mercury concentrations in dental-unit wastewater John Michael Panganiban and Ian Jasper Ocampo Objective: This study was undertaken to determine whether iodine used to control bacteria in dental unit wastewater could increase mercury concentrations in dental wastewater. Introduction: Two of the major concerns in dentistry are biofilm in dental unit waterlines and the contamination of dental unit wastewater with mercury. Biofilms are microscopic communities that consist
