  • European water policies and human health — Combining reported environmental information

    Society depends on the satisfactory and sustainable management of water. Historically, the primary purpose of water treatment was to protect human health, through reducing disease being transmitted through water. Subsequent measures to address environmental concerns have broadened our expectations of what water and waste water treatment should deliver. This report considers three pieces of EU ...

  • Treatment of drinking water containing iron using Electrocoagulation

    Electrocoagulation (EC) technique was adopted for the treatment of iron containing drinking water using a reactor of 3 l capacity having 1 l liquid volume. Experimental investigation was carried out to observe the effect of different operating parameters such as pH, current density, inter-electrode distance and conductivity on the removal of iron from the iron-rich aqueous solution prepared with ...

  • Drinking Water Aesthetics Improve with Ozone Treatment

    High quality water sources for municipal use are dwindling, forcing utilities to seek alternate water sources. Many times, aesthetics are the only problem preventing the use of these alternate water sources for potable purposes. Although typically used as a disinfectant, ozone offers municipal water purveyors the benefits of being the strongest commercially available oxidizing agent (Table 1). ...

  • Algae control in drinking water treatment - case study

    For the Ministry of Agriculture in Cyprus, LG Sound b.v installed 33 LG Sonic, ultrasonic devices in the Limassol water treatment plant, to prevent bad odour and taste to the water caused by geosmins in the water. The earthy taste problem persisted during summer of 2010 and various physical, chemical and biological tests were done in order to check the process efficiency, which showed problems ...

  • Chlorites Control in European Drinking Water Treatment Plants

    ABSTRACT The paper reports initial results for experiments carried out at Fortore drinking water treatment plant aimed at controlling chlorites. Research was performed in parallel with a full-scale drinking water plant (Fortore, Italy) and a pilot plant at Mosina water treatment plant which supplies potable water to the city of Poznań (Poland). Both plants operated with pre-disinfection ...

  • Drinking water treatment - understanding the processes and meeting the challenges

    On and follow Natural organic matter (NOM) derived from soil and vegetation in water catchments is the key factor influencing most, if not all water treatment processes. The structure of the NOM and its involvement in water treatment processes requires better understanding. It seems likely that a better understanding of NOM reactions could lead to far better predictive capacity for water ...

  • Evaluation of chitosan as a natural coagulant for drinking water treatment

    Chitosan, a natural biopolymer, was evaluated for its ability to be used as a coagulant to treat water for potable use both in isolation and in combination with other water treatment technologies, specifically ion-exchange and activated carbon. Chitosan was found to be very effective for particle removal at doses far below those required for equivalent turbidity removal by inorganic coagulants. ...

  • Biological drinking water treatment Hong Kong

    The water treatment works takes water from the river Dongjiang in the Guangdong Province north of Hong Kong. The raw water has an average turbidity level of around 11 NTU and contents, among other things, ammonia and manganese. Water temperatures range from 12 to 34oC.   During planning of the waterworks ...

  • Distillation treatment and removal of contaminants from drinking water

    Distillation treatment typically removes most of the dissolved materials. In addition, the boiling process kills biological contaminants. Nevertheless, there are certain volatile and semi-volatile organic compounds that may not be removed by distillation (CDPH 2009). Organic compounds that boil at temperatures greater than the boiling point of water (some pesticides) can be effectively removed ...

  • Control-design methodology for drinking-water treatment processes

    The performance of a drinking-water treatment plant is determined by the control of the plant. To design the appropriate control system, a control-design methodology of five design steps is proposed, which takes the treatment process characteristics into account. For each design step, the necessary actions are defined. Using the methodology for the pellet-softening treatment step, a new control ...

  • 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 ...

  • 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 ...

  • Organophosphate Pesticide Degradation Under Drinking Water Treatment Conditions

    Chlorpyrifos (CP) was used as a model compound to develop experimental methods and prototype modeling tools to forecast the fate of organophosphate (OP) pesticides under drinking water treatment conditions. CP was found to rapidly oxidize to chlorpyrifos oxon (CPO) in the presence of free chlorine. The primary oxidant is hypochlorous acid (HOCl); thus, oxidation is more rapid at lower pH (i.e., ...

  • Drinking water treatment, AFM replaces sand in sand filters

    Drinking Water Treatment by AFM, 30% - 80 improvement in sand filter performance Cryptosporidium problem and THM's eliminated. All sand filter will suffer to some degree from bacterial fouling. The alginates excreted by the bacteria cause coagulation of the sand grains which in turn leads to wormhole channeling of water through the filter bed. The worm holes provide a conduit for the ...

  • Planning and installation of a drinking water treatment in Gunungkidul, Java, Indonesia

    The district of Gunungkidul on Java Island in Indonesia is affected by an acute water shortage, especially during dry seasons. Because of its karst topography, rainfall percolates rapidly into underground caves, limiting surface storage. As a consequence, potential sources of water to supply the local population are rainwater and water derived from underground caves. However, water availability ...
