  • 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 ...

  • 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 ...

  • 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 ...

  • 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. A biofilm consists of living and dead organic and inorganic material collected on a surface, which in ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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.
