  • Case Study: Farm pond sludge and algae remediation

    Problem A 1 ½ acre farm pond located in southeastern Wisconsin was experiencing a severe algae bloom due to high levels of fertilizer runoff from the surrounding farm fields located on the north and east sides of the pond. Farm field runoff drains into the north end of the pond via a 4-inch drainpipe. The pond is further fertilized by the year round population of 6-8 resident ducks and by ...

  • Algae Problems

    Almost everywhere where water is being stored, algae problems may occur. When water is stagnant, has a high temperature or a high concentration of Nitrates and Phosphates, an algae bloom might occur, which can cause several problems. Blue-green algae growth can cause a foul odour to the water, a layer of scum on the surface and even pose a health risk. Green algae may colour the water green, look ...

  • Case study - Algae control in fire reservoir

    In July 2011, a fire reservoir in Uhy, Czech Republic, was treated with two LG Sonic e-line devices. The water surface was covered by mats of filamentous algae. The Challenge: Control Filamentous Algae Located in Uhy, near Prague (Czech Republic), the 3000 m³ water reservoir for fire extinguishing and bathing purposes was completely covered with filamentous algae. For ...

  • Algae Removal case study

    Best results are achieved with standing water or contained systems. The product works by eating the nutrients that the Algae require thus preventing growth. When used as directed the products are harmless to people and marine life. Algae thrive on nutrients that are present in water, probably due to run off from fields and or treated water discharge. The algae can be controlled very easily, ...

  • Operation of an integrated algae pond system for the treatment of municipal sewage: a South African case study

    Integrated algae pond systems (IAPS) combine the use of anaerobic and aerobic bioprocesses to effect sewage treatment. In the present work, the performance of IAPS was evaluated to determine the efficiency of this technology for treatment of municipal sewage under South African conditions. Composite samples were analysed over an 8 month period before and after tertiary treatment. ...

  • Sunlight-Blocking Covers Control Algae, Reduce Operational Costs at California Utility

    The Utility: The Santa Clara Valley Water District (the District) manages an integrated water resources system that includes the supply of clean, safe water, flood protection, and stewardship of streams on behalf of Santa Clara County's 1.8 million residents. The district effectively manages 10 dams and surface water reservoirs, three water treatment plants, an advanced recycled water ...

  • Ultrasound technology in water treatment: Algae control and reduction of biofilm formation

    Recent research projects have underlined the potential of ultrasound as a chemical free treatment in water-related applications. This article reviews the use of ultrasound produced by the LG Sonic technology, with a focus on wastewater, irrigation and aquaculture applications. Sound Sound can be described as mechanical energy transmitted by pressure waves in a material medium. Thus, sound can ...

  • Pilot plant study for one year: water quality management and algal control of sustainable urban stormwater ponds

    Pond structures as cost-effective "source control" drainage techniques that can be applied to reduce the risk of downstream flooding and to recycle stormwater. There are no widely accepted performance and water quality management data on stormwater ponds, yet there is a need for operation and maintenance guidelines, coupled with data on reliability, economics and public acceptance. The purpose of ...

  • Ecological impacts of fluridone and copper sulphate in catfish aquaculture ponds

    Fluridone and copper sulphate are often used for controlling macrophytes and algae in aquaculture ponds. The present study examined the ecological effects of these chemicals on macrophyte, phytoplankton, and zooplankton biomass, plankton community structure, water quality parameters, and fish survival and yield in catfish culture ponds using a randomized complete block design. The estimated ...

  • Nitrogen removal in maturation waste stabilisation ponds via biological uptake and sedimentation of dead biomass

    In this work a set of experiments was undertaken in a pilot-scale WSP system to determine the importance of organic nitrogen sedimentation on ammonium and total nitrogen removals in maturation ponds and its seasonal variation under British weather conditions, from September 2004 to May 2007. The nitrogen content in collected sediment samples varied from 4.17% to 6.78% (dry weight) and calculated ...

  • Effect of algal recycling rate on the performance of Pediastrum boryanum dominated wastewater treatment high rate algal pond

    Recycling a portion of gravity harvested algae promoted the dominance of a rapidly settling colonial alga, Pediastrum boryanum (P. boryanum) and improved both biomass productivity and settleability in High Rate Algal Pond (HRAP) treating domestic wastewater. The effect of algal recycling rate on HRAP performance was investigated using 12 replicate mesocosms (18 L) that were ...

  • Algal production in wastewater treatment high rate algal ponds for potential biofuel use

    Wastewater treatment High Rate Algal Ponds with CO2 addition could provide cost-effective and efficient tertiary-level wastewater treatment with the co-benefit of algal biomass production for biofuel use. Wastewater grown algal biomass can have a lipid content of 10–30% of dry weight, which could be used to make biodiesel. This research investigated algal biomass and total lipid production by two ...

  • Nutrient removal in wastewater treatment high rate algal ponds with carbon dioxide addition

    The influence of CO2 addition to high rate algal ponds (HRAPs) on nitrogen removal was investigated using two pilot-scale HRAPs operated with different hydraulic retention times (HRT: 4 and 8 days), and was compared to the nitrogen removal by the 8-day HRT pond before CO2 addition was installed. Nitrogen balances were calculated by partitioning total nitrogen into organic and inorganic nitrogen ...
