  • How Installing Arsenic Drinking Water Treatment Can Save Your Life

    Arsenic is an element so associated with its toxicity and harmful effects on the human body that the word itself is often used for any kind of general poison. While the exact ways that exposure to the metalloid attacks various organs and systems is still not fully understood, studies throughout the scientific community are continually determining that ingesting arsenic through drinking water can ...

  • The Benefits of Biological Treatment for Drinking Water

    The biological treatment of drinking water is undertaken using both organic and inorganic contaminants, and can be used to treat groundwater and surface water. These contaminants, contrary to what the name implies, are applied to strip away the factors that make the water unsafe for drinking until it is potable—meaning drinkable. If you would like to learn more about the benefits of ...

  • 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 ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Solutions for Safe Drinking Water Through Biological Water Treatments

    Most people across the U.S. expect to turn on their faucets and have immediate access to clean drinking water. The truth is, it wasn’t until 1974 that Congress passed the Safe Water Drinking Act with the goal of regulating the nation’s public water supply. Over the years, the SWDA has been amended to include water sources as well, such as rivers, lakes, springs and groundwater wells ...

  • Fouling analysis of polysulfone ultrafiltration membranes used for drinking water treatment

    Natural organic matter (NOM) plays a significant role in the fouling of ultrafiltration membranes in drinking water treatment processes. For a better understanding of the interaction between fractional components of NOM and polysulfone (PS) ultrafiltration membranes used for drinking water treatment, fouling and especially the physically irreversible fouling of natural organic matter were ...

  • Drinking Water Treatment Municipality of Latulipe-et-Gaboury, Quebec

    Latulipe-et-Gaboury is a small municipality of about 330 inhabitants in the Abitibi-Témiscamingue region. Its drinking water requirements are 270 m3/day. The town"s water source is a lake (Lac de l"Aqueduc) which appears to be fed directly by a spring. Since there is no discharge of water aside from seepage and evaporation, algae tends to form in the lake during the summer months. As shown ...
