  • Electronic Water Treatment Provides a Clean Line for Food and Drink Production

    The USA’s food and drink producers spend billions of dollar’s each year in downtime, increased energy bills and the early renewal of capital equipment caused by hard water limescale blocking lines and leaving calcium carbonate deposits on water fed equipment.  Scale and sludge formation are the result of the precipitation of compounds that are ...

  • 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 ...

  • Health effects of disinfection by-products in Australian drinking waters

    The disinfection of drinking water has greatly diminished the occurrence of diseases known to be caused by water-borne pathogens, but technological advances subsequent to the initial discovery of chloroform in 1974 have enabled the identification of a plethora of Disinfection By-Products (DBPs), particularly trihalomethanes (THMs), that may have injurious health effects on humans. DBPs are widely ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Tracking disinfection by-products and arsenic removal during various drinking water treatment trains

    In the central Banat region (Northern Serbia), groundwater is used as a drinking water source. Raw water originates from a 40–80 m and 100–150 m deep layer. It contains a high amount of natural organic matter (DOC = 9.17±0.87 mg C/L) with a trihalomethanes formation potential of 448±88.2 μg/L and a haloacetic acid formation potential of 174±68.9 μg/L. A high amount of arsenic (86.0±3.4 μg/L) is ...

  • How can drinking water treatments influence chlorine dioxide consumption and by-product formation in final disinfection?

    In this study water samples of different origins (subalpine lake, artificial lake and river) were treated by pre-oxidation, coagulation/flocculation, adsorption on granular activated carbon and disinfection. Different laboratory-scale tests were carried out to evaluate the treatment impact on ClO2 consumption in disinfection and on the formation of disinfection by-products (trihalomethanes, ...

  • Orthophosphate removal from aqueous solutions using drinking-water treatment sludge

    Drinking-water treatment sludge (DWTS) is a by-product generated during the production of drinking water where iron hydroxides are the main component of the sludge. The aim of the study presented here was to determine the effectiveness of using ferric sludge from two underground water treatment stations to remove orthophosphates from a model solution. The analyses were performed in static ...

  • Monitoring of three drinking water treatment plants using flow cytometry

    A 4-month sampling campaign has been conducted for the monitoring of three drinking water treatment plants using flow cytometry and culture-based methods to provide information related to changes in bacterial concentration according to treatments. Flow cytometry is a fast and user-friendly technique enabling bacteria quantification and viability assessment in less than 1 hour. Specific profiles ...

  • 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., ...

  • Disinfection by-products in drinking water – a case study on Calgary, Alberta, Canada

    Disinfection by-products (DBPs) have been monitored in Calgary's drinking water for approximately 15 years. The variability of the DBPs has typically exhibited similar patterns over the period of monitoring. Due to the nature of the surface waters supplying the water treatment plants, the level of DBPs was largely influenced by surface runoff events where the level of natural organic matter (NOM) ...

  • Behaviour of brominated and chlorinated flame retardants during drinking water treatment

    Flame retardants are chemicals that are added to plastic materials in order to prevent them from catching fire and to slow down the burning process. Due to the widespread occurrence of flame retardants in the environment, it can be expected that especially the more hydrophilic compounds already contaminate raw water resources of water utilities. In this paper results of laboratory-scale ...

  • Dissolved organic nitrogen (DON) in a full-scale drinking water treatment plant

    Dissolved organic nitrogen (DON) is currently considered as one of the most important parameters in drinking water treatment due to its potential to form toxic nitrogenous disinfection by-products (N-DBPs). A comprehensive investigation was made in this study on the variation of DON in a full-scale drinking water treatment plant with a treatment train of coagulation/sedimentation, biofiltration ...

  • Students tackle disinfection issues using drinking water treatment simulator

    In a recent innovative assignment, Civil Engineering students at the University of Toronto pooled their talents to address a growing drinking water issue. Teams of students in the graduate course taught by Dr. Robert Andrews used computer simulation to determine how best to optimize a water treatment plant to meet tough new standards for disinfectant residual and disinfectant by-product (DBP) ...

  • The effect of chlorine and combined chlorine/UV treatment on coliphages in drinking water disinfection

    Chlorine disinfection is a globally used method to ensure the safety of drinking water. However, it has not always been successful against viruses and, therefore, it is important to find new methods to disinfect water. Seventeen different coliphages were isolated from the treated municipal wastewater. These coliphages and MS2 were treated with different dosages of chlorine in drinking water, ...
