  • Biological iron and manganese removal, pilot and full scale applications

    Both manganese and iron are found in surface and ground waters at varying concentration levels. When present even at low concentrations they can be linked to the following problems: discolouration, turbidity and taste problems or form slime and iron noxide or manganese dioxide accumulations in pipes. Both metals promote the growth of certain types of chlorine tolerant micro-organisms in water ...

  • Chloramines

    OVERVIEW When chlorine is added to a water supply containing certain organics, the formation of halogenated organics occurs. Called 'trihalogenated methanes' (THM's) these reaction products are suspected carcinogens and maximum allowable limits in municipal supplies are imposed by the U.S. Environmental Protection Agency (EPA). To reduce the potential for the formation of THM's, many U.S. ...

  • The advantages and benefits of aerobic cometabolism

    Aerobic metabolism yields the energy-transferring molecule TPA at a much higher rate than anaerobic metabolism. The higher energy yield produces a greater viable population. The oxygenase enzymes involved in the cometabolism of chlorinated solvents are not induced by the presence of contaminants, so a high microbial population has a proportionately high yield of oxygenase enzymes. Aerobic ...
