  • NEW BLOG ENTRY: Water Monitoring Goals

    The concept of biological filtration has become a common means to remove organics prior to disinfection to minimize formation of disinfection by-products. However, the tools available to assess biological growth tendencies in biological filters are limited. Heterotrophic Plate Counts and other culture-based methods take days to obtain results, only measure very small portions of the true ...

  • A Case for Point-of-Use RO Ultrapure Water Systems

    ULTRAPURE WATER CRITERIA - AN OVERVIEW 'Pure water' is a relative term. Practically speaking, no water, naturally occurring or treated by man, consists solely of H2O molecules. Forever in pursuit of achieving equilibrium with its surroundings, water has unique characteristics that result in its ability to dissolve most matter. This property of water to dissolve and transport materials is ...

  • A critical evaluation of two point-of-use water treatment technologies: can they provide water that meets WHO drinking water guidelines?

    Point-of-use (POU) technologies have been proposed as solutions for meeting the Millennium Development Goal (MDG) for safe water. They reduce the risk of contamination between the water source and the home, by providing treatment at the household level. This study examined two POU technologies commonly used around the world: BioSand and ceramic filters. While the health benefits in terms of ...

  • Hom’: a simple point of use water treatment device

    This study sought to explore a locally assembled ‘Hom’ point of use water treatment device by assessing aspects of its performance and possible effects of using it on compliant households and communities. The conceptual framework highlights poverty and environmental degradation as causes and consequences of one another, with ill-health caused by water-borne diseases reinforcing both to form a ...

  • Analytical Devices for the Measurement of Water Vapor and Hydrocarbon Dew-Point in Natural Gas

    Introduction The determination of water vapor (water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to corrosion of plant and equipment. Furthermore, water vapor present in natural gas streams affects the ...

  • The relationship between technology and functionality of rural water points: evidence from Tanzania

    This paper presents an analysis of the relationships between technology of water point, management related practices and functionality over time through an extensive water point mapping study made in 15 rural districts of Tanzania, which covered 15% of the total rural population of the country. Results show irregular functionality rates at district level by technology, but reveal statistical ...

  • Water quality monitoring with online change-point detection methods

    We develop an approach for water quality time series monitoring and contamination event detection. The approach combines affine projection algorithms and an autoregressive (AR) model to predict water quality time series. Then, we apply online change-point detection methods to the estimated residuals to determine the presence, or not, of contamination events. Particularly, we compare the ...

  • A compact point-of-use water purification cartridge for household use in developing countries

    Simple, low-cost household interventions are known to be effective in lowering the incidence of waterborne diseases in developing countries. However, high costs along with operational and maintenance issues have prevented the successful adoption of these interventions among the affected communities. To address these limitations, a cost-effective, gravity-driven water purification cartridge has ...

  • Point-of-use chlorination of turbid water: results from a field study in Tanzania

    Household-based chlorine disinfection is widely effective against waterborne bacteria and viruses, and may be among the most inexpensive and accessible options for household water treatment. The microbiological effectiveness of chlorine is limited, however, by turbidity. In Tanzania, there are no guidelines on water chlorination at household level, and limited data on whether dosing guidelines ...

  • Demonstration and evaluation of germicidal UV-LEDs for point-of-use water disinfection

    Ultraviolet (UV) irradiation is a common disinfection option for water treatment in the developed world. There are a few systems installed in developing countries for point-of-use treatment, but the low-pressure mercury lamps currently used as the UV irradiation source have a number of sustainability issues including a fragile envelope, a lifetime of approximately one year, and they contain ...

  • Remote Sensing Techniques to detect Surface Water Quality Constituents in Coastal and Inland Water Bodies from Point or Non Point Pollution Sources

    This study demonstrates that point and non-point pollution sources in coastal and inland water bodies can be identified and monitored using remote sensing techniques so early corrective action can be take to prevent or minimize Harmful Algae Blooms (HAB’s). By tracking these changes in the remote sensing images could be very beneficial in establishing cleanup and restoration efforts for improving ...

  • Development of point-of-use water disinfection technology using ceramic water filter and electrochemical hybrid system

    The efficiency of water disinfection using a ceramic water filter and electrochemical hybrid system was investigated. Escherichia coli O157:H7 was effectively inactivated even when a storage battery, charged using a solar panel device, was used for the electrolysis process. During electrolysis, the rate of microbial inactivation was higher at higher initial Cl− ...

  • Research of trace metals as markers of entry pathways in combined sewers

    Combined sewers receive high toxic trace metal loads emitted by various sources, such as traffic, industry, urban heating and building materials. During heavy rain events, Combined Sewer Overflows (CSO) can occur and, if so, are discharged directly into the aquatic system and therefore could have an acute impact on receiving waters. In this study, the concentrations of 18 metals have been ...
