  • Tools to improve water quality

    This post is part of a series on World Water Week, an annual event designed to draw attention to and discuss global water issues. Read more posts in this series. Agricultural production often comes at the expense of water quality. As my colleague, Mindy Selman, ...

  • Ultrasonic technology in cooling towers

    Ultrasound technology is an effective and environmentally friendly method to minimise chemical consumption and improve the efficiency of a cooling tower, says Ander Paz Blazquez. Low-intensity ultrasound has been used for more than a decade in order to control algae and biofilm growth. Latest innovations have concluded that effective algae control is achieved through the use Ultrasound ...

  • Water quality at Blue Plains improved case study

    The Blue Plains Wastewater Treatment Plant in Washington D.C. is the largest advanced wastewater treatment plant in the world. The District of Columbia’s Water and Sewer Authority (WASA) operates the plant. LimnoTech’s expertise in sewer system and river modeling helped WASA make decisions about two complex programs: combined sewer overflow (CSO) control to improve local water ...

  • REMOVING LIMESCALE IMPROVES WATER QUALITY IN POULTRY FARMS

    Water is one of the most important nutrients in poultry production.  About 70 per cent of a bird’s body is made up of water - eggs contain around 65% water. Birds are constantly losing water in egg production, so there is an obvious need for constant replenishment.  Water intake is almost twice the weight of ...

  • 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 — ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Simultaneous corrosion control and water quality improvement in water distribution systems

    The effects of different dosages of sodium hexametaphosphate and sodium orthophosphate on corrosion inhibition and water quality in two model water distribution systems, and the corrosion inhibition mechanism on pipe walls were investigated. Results show that adding sodium hexametaphosphate and sodium orthophosphate can not only provide a remedy for the damaged cement coating surface, but ...

  • 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 ...

  • Using Permeable Eco-Paving to Achieve Improved Water Quality for Urban Pavements

    This paper describes the planning, design and construction of a permeable pavement as a practical demonstration of the benefits of eco-paving in Australian environmental management. The paper addresses the use of permeable pavements as part of a Water Sensitive Urban Design that allows infiltration of stormwater, reduction of pollutants and slow reticulation of the stormwater to an ecologically ...

  • How to choose the most cost-effective methods for improving water quality

    Agricultural run-off can contain pesticides, sediment particles and nitrates and is a major threat to the health of the sea. Although there are policy frameworks to reduce run-off water, they often don’t clearly explain how to maximise benefits. A new study provides an economic framework that prioritises methods based on their cost-effectiveness, which could help policymakers to reduce 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 ...

  • A New Strategy to Improve Water Quality—One Targeted Watershed at a Time

    Water quality in the United States remains a major environmental and policy challenge. Water pollution is also a growing and serious problem across much of the world. Tackling water quality problems, particularly from diffuse sources such as agricultural farm fields, is a substantial challenge and much can be learned from the U.S. experience. ...

  • Water Quality and Habitat Improvement at a Decommissioned Phosphate Fertilizer Facility

    As part of their long-term site restoration plan, ICI created within the former prefiltration pond a pond/wetland/upland wildlife habitat to benefit local species of birds, mammals, and plants, along with a myriad of other living creatures. The site already supported a wide range of flora and fauna, which has been enhanced by this restoration. The completed project now provides for selected areas ...

  • Improvement of water-quality environment in reservoir models using flow networks

    It is known that thermal stratification and environmental problems such as water quality deterioration occur in water reservoirs. One principle cause is the stagnation of water in the reservoirs, which leads to the problems of density stratification, nutrient enrichment of algae and others. Various methods such as deep-layer mixing and forced-air injection have been utilised to counter these ...

  • Designing a constructed wetland for the detention of agricultural runoff for water quality improvement

    Received for publication December 18, 2008. The goal of this study was to construct a wetland that would detain runoff from a 162-ha watershed for the purposes of improving water quality. The volume of runoff that needed to be detained was determined to be that amount coming off the 162-ha watershed consisting of 146 ha of cultivated crop land and 16 ha of pasture that exceeded the amount that ...

  • Removal of Fallen Leaves Can Improve Urban Water Quality

    The timely removal of leaf litter can reduce harmful phosphorus concentrations in stormwater by over 80 percent in Madison, Wisconsin, according to a recent U.S. Geological Survey study. Autumn leaf litter contributes a significant amount of phosphorus to urban stormwater, which then runs off into waterways and lakes. Excessive amounts of ...

  • Neuthox improves the water quality by removing unwanted bacteria - Case Study

    NEUTHOX removes biofilm in cooling tower and leaves the water system completely free of unwanted bacteria Using an electrolysis process of saltwater the ECA generator produces the liquid NEUTHOX, which contains hypochlorous acid, and is highly efficient in eliminating bacteria.
