  • Raw water intake monitoring - Case study

    The Situation Hydrocarbons in municipal water supplies, including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through ...

  • An approach for determining the most critical among a suite of chemical contaminants at a drinking water intake

    An integrated approach for the identification and assessment of the most critical chemical contaminant(s) at a drinking water intake has been developed. It involves the determination of a threshold or critical raw water concentration (CRWC) for target contaminants using the observed overall removal efficiency of a specific water treatment plant (WTP) and regulated drinking water concentrations ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • Algal control and enhanced removal in drinking waters in Cairo, Egypt

    Algal blooms at the major water treatment plants in Egypt have been reported since 2006. While previous studies focused on algal types and their correlation with disinfection by-products, correlation between raw water quality and algal blooms were not explored. Therefore, a survey of Nile water quality parameters at a major water intake in the Greater Cairo Urban Region was conducted from ...

  • Monitoring once through cooling water - Case study

    The Situation Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil.  These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often ...

  • Seawater reverse osmosis system for supplying potable water for airport in saudi arabia

    The Background Saudi Arabia General Authority of Civil Aviation (GACA) is responsible for constructing, managing, operating, and maintaining airports and air navigation infrastructure in Saudi Arabia. The city lacked adequate water production and distribution systems around the airport. GACA’s objective was to increase water production to meet projected growth in demand, and ...

  • Linking drugs of abuse in wastewater to contamination of surface and drinking water

    The concentrations of 17 drugs of abuse, including cocaine, several amphetamines, opioid drugs, and 2 metabolites—benzoylecgonine, a metabolite of cocaine, and 2‐ethylidene‐1,5‐dimethyl‐3,3‐diphenylpyrolidine, a metabolite of methadone—were investigated in an urban watershed that is heavily impacted by discharges of municipal wastewater. The artificial sweetener sucralose was also monitored as ...

  • Invasion of the non-indigenous nuisance mussel, Limnoperna fortunei, into water supply facilities in Japan

    ABSTRACTThe aquatic nuisance mussel, Limnoperna fortunei, arrived in Japan before 1987 possibly with the Asian clam imported as food from mainland China. Now the mussel’s distribution has spread to two river systems in central Japan. Water authorities reported several cases of damage caused by L. fortunei. Most cases of damage were caused by dead mussels clogging small diameter pipes for raw ...

  • Estimation of pathogen concentrations in a drinking water source using hydrodynamic modelling and microbial source tracking

    The faecal contamination of drinking water sources can lead to waterborne disease outbreaks. To estimate a potential risk for waterborne infections caused by faecal contamination of drinking water sources, knowledge of the pathogen concentrations in raw water is required. We suggest a novel approach to estimate pathogen concentrations in a drinking water source by using microbial source ...
