  • Modeling of eutrophication and strategies for improvement of water quality in reservoirs

    The purpose of this study is to survey the thermal regime and eutrophication states in Ilam reservoir in Iran as the case study. For this purpose and to find solutions for improving the water's quality in the reservoir, two general strategies for reducing the entering pollution loads and water depletions from the reservoir's outlets were analyzed by use of the CE-QUAL-W2 model. Results of the ...

  • Water quality improvement of industrial shrimp ponds

    Agriculture has been one of the most major economic sources in Tien Giang province. Because waste generation from ISP process has not been completely controlled, it has affected the water quality seriously. Samples collected at three stages of shrimp ponds and surface water (rivers, canals) were assessed. The results showed that water quality in rivers and canals is contaminated by organic and ...

  • Scientists submit suggestions for improved European water quality

    Although the European Water Framework Directive has been in place since 2000, some say revisions are needed to help the continent achieve even better water quality. Scientists from across Europe have carefully looked at the document to determine what is needed to help make the framework more effective. The directive, which addresses water pollution, says all bodies of water in Europe — ...

  • Additive blending improves fuel quality

    Fuel additive is substance which is added to fuel (to gasoline, kerosene, diesel and so on) for improvement of their properties. Depending on the quality of initial fuel, function, property and efficiency of additives, their combinations in a commodity product are various. The components content in fuel varies from 2 to 20% depends from the weight. Modern motor fuels made from basic fuel with ...

  • Meeting regulations and improving quality case study

    A UK-based waste oil collector was using emulsifiers and heat to drop water out of waste lube oils and fuels. The processed oil with 0.5-1.0% water was being filtered in a centrifuge. The company installed Sequoia’s efficient water evaporation equipment which produces oil with less than 0.1% water. As a result, the centrifuge works more efficiently. Ultimately, the company makes a recycled ...

  • Improving water quality communications at beaches: input from stakeholders

    Objectives: Water quality communication practices vary widely and stakeholder input has not played a role in defining acceptable levels of risk. Although the 2012 Recreational Water Quality Criteria (RWQC) emphasize the importance of promptly notifying the public about hazardous conditions, little is known about the public's understanding of notifications, or about levels of risk deemed ...

  • Alien fish eradication improves water quality at Century City - case study

    NCC planned and implemented an alien fish eradication programme to solve a looming water quality crisis at one of South Africa’s premier retail, office and residential developments. Century City, first established in 2002, is a large mixed-use development covering 250 hectares of land along the N1 near the centre of Cape Town. It includes the Canal Walk shopping mall, Ratanga Junction ...

  • Alum application to improve water quality in a municipal wastewater treatment wetland

    Received for publication January 18, 2008. Nutrient removal in treatment wetlands declines during winter months due to temperature. A 3-mo (wintertime) mesocosm study was conducted to determine the effectiveness of alum in immobilizing P as well as other nutrients during this period of reduced treatment efficiency. Eighteen mesocosms, triplicate alum, and three controls or no alum were ...

  • Improving Water Quality: Using Technology to Advance the Goals of Watershed Planning

    In 2003 the Pennsylvania Environmental Council teamed with Buchart-Horn, Inc. to conduct and prepare a Watershed Conservation Plan (WCP) for the 510 square mile Conewago Creek Watershed located in Adams and York Counties, Pennsylvania. The project was funded in part by a grant received from the Pennsylvania Department of Conservation and Natural Resources (DCNR), Community Conservation ...

  • Minnesota debates phosphorus discharge limits for improved water quality

    City leaders across the Minnesota River Basin are protesting proposed phosphorus standards, which they contend will be too expensive and have little or no effect on water quality. In January, 41 of the 147 Minnesota cities in the basin outlined their objections in a letter to the governor and the Minnesota Pollution Control Agency. Many of these cities’ wastewater treatment plants ...

  • Control Algae and Improve the Water Quality in Waste Stabilization Ponds

    Due to population growth, accelerated urbanisation and economic development, the quantity of waste water generated is increasing globally. Mainly in low-income areas, a large proportion of the waste water is discharged directly in the environment. When the waste water is treated, the treatment plants may not remove certain pollutants that can have a negative impact on the people and ecosystem. ...

  • Constructed wetland for water quality improvement: a case study from Taiwan

    In Taiwan, more than 20% of the major rivers are mildly to heavily polluted by domestic, industrial, and agricultural wastewaters due to the low percentage of sewers connected to wastewater treatment plants. Thus, constructed or engineered wetlands have been adopted as the major alternatives to clean up polluted rivers. Constructed wetlands are also applied as the tertiary wastewater treatment ...

  • Improving collected rainwater quality in rural communities

    The country of Mexico is facing serious problems with water quality and supply for human use and consumption in rural communities, mainly due to topographic and isolation. In Mexico the average annual precipitation is 1,500 cubic kilometers of water, if 3% of that amount were used, 13 million Mexicans could be supplied with drinking water that they currently do not have access. Considering the ...

  • Gravity driven membrane filtration system to improve the water quality in rainwater tanks

    The characterisation of rainwater in metropolitan Sydney and in rural New South Wales was undertaken. The results showed that factors such as the lack of vehicular traffic, air pollution and urban contamination meant that rural rainwater water quality was better. The rain water collected in both metropolitan and rural areas generally complied with the 2004 Australian Drinking Water Guidelines ...

  • Sustainable improvement of drinking water quality by nanofiltration powered by renewable energy

    Desalination membrane technology is increasingly used for water production. However, the main disadvantage of desalination is related to energy consumption and CO2 emissions, so desalination powered by renewable energy (RE) is getting interest. In this study nanofiltration (NF) membranes have been used for drinking water quality improvement in a pilot plant (50 m3/day) powered by RE ...
