  • A Regulatory Perspective on Maintenance of Disinfection Systems

    ABSTRACTThe Clean Water Act contains requirements to set water quality standards for all contaminants, including bacterial contaminants, in surface waters. Wastewater treatment cannot be expected to remove all of the bacterial contaminants, and as a result, many organisms remain in the waste stream. Therefore, disinfection of treated wastewaters is designed to reduce bacterial numbers to a safe ...

  • Industrial applications of new sulphur biotechnology

    The emission of sulphur compounds into the environment is undesirable because of their acidifying characteristics. The processing of sulphidic ores, oil refining and sulphuric acid production are major sources of SO2 emissions. Hydrogen sulphide is emitted into the environment as dissolved sulphide in wastewater or as H2S in natural gas, biogas, syngas or refinery gases. Waste streams containing ...

  • Synthesis, activity and thermal stability of gold nanoparticle on modified nh4-y type zeolite for cooxidation

    Carbon monoxide (CO) is a gaseous pollutant which enters the atmosphere from four major sources: fossil fuel combustion and industrial emissions, biomass burning, oxidation of CH4, and oxidation of hydrocarbons. The presence of CO causes problems to human health, particularly in cases of locally high concentrations, and affects the oxidizing capacity of the troposphere. Automobile emissions are ...
