  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
