  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Neuthox in agriculture - improving water quality and increasing revenue - Case Study

    Adding NEUTHOX to the water supply will improve weight gains, and lower the mortality rate. NEUTHOX is proven to: Reduce bacteria levels in the local water supply Remove biofilm in the water system Reduce animal self-contamination of drinking water Be an eco-friendly, non-toxic and economical solution ...

  • 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. ...

  • 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 ...

  • 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 ...
