  • Efficacy of drinking-water treatment residual in controlling off-site phosphorus losses: A field study in Florida

    Received for publication August 23, 2008. Land application of drinking-water treatment residuals (WTR) has been shown to control excess soil soluble P and can reduce off-site P losses to surface and ground water. To our knowledge, no field study has directly evaluated the impacts of land application of WTRs on ground water quality. We monitored the effects of three organic sources of P (poultry ...

  • The comparative study of trihalomethanes in drinking water

    Abstract: The purpose of this study was to assess exposure of four trihalomethanes (chloroform, bromodichloromethane, dibromochloromethane and bromoform) in drinking waters of Okinawa Island and Samoa. Trihalomethanes compounds were determined in the drinking water samples that were collected from the selected consumption sites and treatment plants of both Okinawa and Samoa in 2003-2004. The ...

  • Development of efficient characterization parameters for activated carbon used in drinking water treatment

    In many drinking water treatment facilities with an activated carbon (AC) purification step, polar and hydrophilic molecules are substances of concern. Many of the current test methods for AC do not really reflect AC's adsorption capacity for these substances. To develop a fast and economically reasonable parameter that characterizes AC's ability to remove these compounds, three ...

  • West Columbia, SC, municipal drinking water

    The Lake Murray Water Treatment Plant (LMWTP) in West Columbia, S.C., was dedicated in 1991 with a capacity of 6 million gal per day (mgd). With upgrades completed in 2007, the plant has a current capacity of 22.5 mgd. Most of the water from LMWTP is sold; 19% of the water is distributed to the system for which the LMWTP management and staff is responsible. 0In the early 1990s, the water ...

  • Water treatment in Brazil

    The challenge Many factories in Brazil do not dispose their sewerage in a professional way. Only big enterprises use facilities to treat their industrial waste water, whereas numerous small and medium-sized enterprises convey their sewerage flow into rivers and brooks or pit drainages. This results in a significant environmental burden and endangers the health of the population. ...

  • Treatment plant protected by effluent monitor at major drinks factory

    The installation of a BioTector continuous TOC (Total Organic Carbon) monitor to police the front end of Cobevco’s wastewater treatment plant has enabled tight control of the treatment process. Delivering results 20 times faster than laboratory techniques, the monitor at the Elton facility in Cheshire provides advance notice of organic overload so that the plant is able to instantly divert ...


  • Clean drinking water for the Orang Asli in Malaysia with Trunz Water Systems

    Malaysia - As a result of littering, overfertilization and environmental influences the raw water sources in the Cameron Highlands are contaminated with virus and bacteria. Consumption of such water leads to major health affecting diseases - and as a chain reaction to less productivity, less income, less education for children and so on. Remote villages of orang asli (aborigines) are concerned of ...

  • Evaluating the efficacy of pre-oxidation for enhancing removal of HAA5 precursors by conventional drinking water treatment

    The formation potentials of five haloacetic acids (HAA5FP) in 13 surface water samples taken from eight cities from northeast to south China were evaluated using the simulated distribution system (SDS) chlorination method. These samples showed a wide range of HAA5FP levels (20 to 443▒μg▒L−1). Four pre-oxidation methods were evaluated for their performance in enhancing HAA5FP removal from six ...

  • Development of a portable filter for arsenic removal from drinking water

    In the present study, different grades of indigenously available activated alumina (AA) were screened for their arsenic removal capacity. For both As(III) and As(V), A1 (Grade 1, 0.3-0.6 mm) activated alumina has shown better removal efficiency. The optimum pH for the adsorption phenomena was around 7.0. Chlorine at a dose of 20 mg/l could completely oxidize As(III) to As(V), which also assured ...
