  • Surveillance and Improvement of Peruvian Drinking Water Case Study

    The surveillance and quality control of public water supplies are vital prerequisites for the protection of public health. In practice however, the two activities of surveillance and quality control are often confused and inadequately implemented, especially in the case of surveillance in less developed countries. The two are clearly distinguished by the World Health Organization (1984): ...

  • Recycle of waste backwash water in ultrafiltration drinking water treatment processes

    In drinking water treatment, ultrafiltration (UF) membrane systems are generally operated at 90 to 95% recovery with production losses resulting from waste residual streams such as backwash water and clean-in-place (CIP) liquid residuals. In drought-prone regions, it may be desirable to apply alternative UF plant design configurations to increase recovery rates and minimize water loss. This ...

  • Update on Mt Pleasant WTP Incorporating the MIEX ® DOC Process and How it Compares With a Plant Operating in Enhanced Coagulation Mode

    Natural organic matter (NOM) is a major factor impacting on water treatment processes. NOM is a precursor of disinfectant by-products (DBP), a food source for regrowth of micro-organisms and makes downstream processes such as membrane filtration and activated carbon less efficient. Reducing NOM in conventional treatment plants can be achieved by using enhanced coagulation, whereby additional ...

  • Rethinking Big Water - Is It Time For A New Approach To Municipal Water Infrastructure?

    Las Vegas has long served as a stereotype of human excess: gambling, drinking, sex, all-you-can-eat buffets. But the latest chapter is playing out away from the Strip, in the part of the valley where two decades of booming development have swelled the population to 2 million residents who rely on a dwindling water supply. Ninety percent of the southwestern U.S. city’s drinking water comes ...
