  • Tertiary Nitrification Process - Case Study

    Our nitrification process was originally developed for ammonia removal from activated sludge final effluent. However, it has since been applied to sludge liquor ("reject water", "centrate" or "filtrate") treatment. It is also suitable for nitrification of potable water sources (e.g. surface or ground water) prior to chlorination, to reduce the formation of chloramines. Ammonia removal down to 1 ...

  • BM Respirometry applied to a novel control strategy of nitrification in a wastewater biological treatment

    In wastewater treatment plants, the biological nitrogen removal (BNR) has acquired critical importance, which makes that in the majority of the cases the overall process control largely depends on the control of this treatment. The normal aerobic process of nitrification is performed by specific aerobic living microorganisms and a lack of information on their bioactivity may be cause of confusion ...

  • Technology development trajectory for drinking water treatment: a comparative study between South Korea, Thailand, and Lao PDR

    This paper reports on a study to compare the technological trajectory of drinking water treatment for the past 30 years, from the 1980s to the 2010s, in South Korea, Thailand, and Lao PDR. There are significant differences in water treatment technology in the three countries, resulting from factors such as national regulations, economic conditions, and water policies. These act either as ...
