  • 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 ...

  • Spectro Scientific`s Third Edition Of The Oil Analysis Handbook

    It has been over two years since the publication of the first edition of Spectro Scientific’s In-Service Oil Analysis Handbook. Our goal was to compile a comprehensive reference book of common in-service oil analysis techniques to help readers understand and choose the right technique and instrumentation for their needs. In-service oil analysis for condition based maintenance covers a wide ...

  • Evaluation of Advanced Water Treatment for Indirect Potable Reuse

    The City of San Diego (City) and MWH recently completed a 18-month pilot testing program to determine the effectiveness of a three-step Advanced Water Treatment (AWT) process to produce water suitable for indirect potable reuse from tertiary water produced at the North City Water Reclamation Plant (NCWRP). This testing program was conducted as part of the City’s Water Reuse Study, which was ...

  • Advanced Water Treatment Solutions for the Food/Beverage Industry

    The agricultural/irrigation industry is one of the most demanding users of water for process applications. The availability of a sustainable supply of clean water is a necessity. Water shortages, reduction of water quality, and environmental issues, have led to an increased awareness of the use of both treated waste water as well as the ...

  • Advanced Lagoon Treatment Technologies for Wastewater Treatment

    Lagoon-based wastewater treatment systems are popular around the world for their simplicity and cost-effectiveness. However, these systems are unable to reliably remove biochemical oxygen demand (BOD) and total suspended solids (TSS) to less than 30 mg/L or achieve nitrification during winter months in cold climates. Several innovative modifications have been developed, which have the potential ...

  • Advanced Water Treatment Technologies May Bring Purified Water to San Diego

    'In four years, half of San Diego may be filling its glasses with tap water that once ran through its toilets,' reported the San Diego Union-Tribune recently. A plan to mix 'repurified water' with the City's raw drinking water reservoir could become a reality, thanks to the wonders of water treatment technology. Such a possibility elicits various reactions including disgust, marvel and fear. ...

  • Immersed Membrane Technology for Advanced Wastewater Treatment & Water Reuse

    A significant segment of the North American population is unserviced by municipal wastewater systems and, with the seemingly, unending growth of residential communities, commercial complexes, industrial parks and support infrastructure, this situation is unlikely to change in the foreseeable future. Traditionally serviced by on-site wastewater treatment units, and often relying on groundwater ...

  • Advanced Water Treatment and Evaporation Systems Produce High Efficiency

    AQUATECH IS CHANGING THE GAME in the water recycling industry through its SmartMOD Modular Evaporator System and HEVAP High Efficiency Evaporation Process for SAGD Water Treatment. For over 30 years, the company has focused exclusively on desalination, water reuse, and zero liquid discharge with water purification technologies suited for global industrial, upstream and ...

  • Use of ultraviolet disinfection and advanced oxidation process for reclaimed water treatment of microcontaminants

    KEY WORDS Innovative Treatment, Advanced Oxidation, Reclaimed Water, Ultraviolet light, Peroxide, Disinfection, Microcontaminants INTRODUCTION Many regions of the United States, experiencing rapid population growth and faced with the challenge of meeting increased water demands, are turning to reclaimed water as an alternative water ...

  • Perfluorinated chemicals (PFCs) in water purification plants (WPPs) with advanced treatment processes

    A series of perfluorinated chemicals (PFCs) surveys were conducted in two water purification plants (WPPs) having ozonation and granular activated carbon (GAC) filtration processes. In each plant, six different processes samples (source water, influent, coagulation-sedimentation effluent, ozonation effluent, GAC filtration effluent, and final tap water) were collected for two times and eight PFCs ...

  • Toxicity of WWTP effluent after advanced treatment (TOXmini)

    The Delft Blue Water project was started to investigate the possibility to produce reusable water for environmental planning purposes and water for greenhouse use. The water board of Delfland stated that the toxicity of the treated water has a toxicity in the same range as that of the location where it might be discharged at. This research was started to investigate the toxicity of the produced ...

  • Chemical monitoring strategy for the assessment of advanced water treatment plant performance

    A pilot-scale plant was employed to validate the performance of a proposed full-scale advanced water treatment plant (AWTP) in Sydney, Australia. The primary aim of this study was to develop a chemical monitoring program that can demonstrate proper plant operation resulting in the removal of priority chemical constituents in the product water. The feed water quality to the pilot plant was ...

  • Determination of the ultrasonic effectiveness in advanced wastewater treatment

    Biological treatment is the most commonly applied method for treatment of wastewaters. However, biological treatment can be inhibited by bacteriotoxic or persistent pollutants present in wastewater (Lifka et at., 2003). As a result, this technology may be incapable of reducing the levels of contaminants below which they are not considered as a potential threat to public health. Therefore, new ...

  • Quantitative microbial risk assessment of drinking water treated with advanced water treatment process

    Campylobacter jejuni is one of the major causes of waterborne disease in Japan. A quantitative microbial risk assessment (QMRA) was conducted to evaluate the health risk caused by this pathogen in drinking water treated with a supposed advanced treatment process including ozonation and granular activated carbon adsorption. Coagulation-sedimentation, rapid sand filtration, ozonation, and ...

  • Degradation of chlorpyriphos in water by advanced oxidation processes

    The degradation of chlorpyriphos by different advanced oxidation processes such as photo-Fenton, TiO2, TiO2/H2O2, O3 and O3/H2O2 was investigated. The photo-Fenton and TiO2 processes were optimized using a solar chamber as light source. The optimum dosages of the photo-Fenton treatment were: [H2O2]=0.01 M; [Fe3 + ]=10 mg l−1; initial pH = 3.5. With these optimum conditions total degradation was ...

  • Enhanced coagulation: a viable option to advance treatment technologies in the South African context

    Laboratory and full-scale experiments were conducted for enhancing the coagulation of stabilised surface waters with high organic content by permanganate preoxidation. It was indicated that permanganate preoxidation enhanced both the processes of coagulation and filtration of selected surface waters, River Songhua water, Qitaihe Reservoir water and Ba Reservoir water. Permanganate preoxidation is ...
