  • Biogas recovery from a temperate climate covered anaerobic pond

    New Zealand has over 1000 anaerobic waste stabilisation ponds treating wastewater from farms and industry. Traditional anaerobic ponds were not designed to optimise anaerobic digestion to produce biogas and are therefore uncovered, releasing biogas to the atmosphere, which can cause odour problems and contributes to GHG emissions. The biogas production and treatment performance of an anaerobic ...

  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

  • Case study - Algae control in a golf course pond

    In July 2011, the golf course pond at the Lethbridge country club was treated with the LG Sonic e-line. The water surface was covered by mats of filamentous algae. The rocks within the pond where covered by Dydimo sp.   The Challenge: Control Filamentous Algae and Diatoms In July 2011, the golf course pond at the Lethbridge country club was treated with LG Sonic. The ...

  • Case study - Algae control in recreational pond

    Located in Craigmyle, Torphins (Scotland), the 3845 square meter pond was covered with dark green pond weed.  An e-line system was installed to control the algae. The Challenge: Green Algae Mats Covering the Pond’s Shores Located in Craigmyle, Torphins, Scotland, the 3,845 m2 pond was covered with dark green pond weed. For years, the image of the pond was ...

  • Build your pond to last with a liquid liner

    Build a pond without providing proper sealing and you'll probably be watching your money getting washed down the drain. Pond cracks, pond holes and pond leaks can be a persistent and costly problem so heading them off before they start in the construction process is a very good idea. That means paying particular attention to lining your ...

  • Case study - Algae control in residential pond

    Eagles Landing is situated on the banks of Hartbeespoort Dam. It has an inland pond surrounded by houses that residents decided to treat their algae problems with LG Sonic e-line technology. The Challenge: Green Algae Mats Covering the Pond’s Shores The residential pond was plagued with heavy thick green algae, had high maintenance requirements, and was an eyesore for ...

  • Case study - Upgrading highly loaded waste ponds to “Bio-Gas Banks”

    Problem: Un-covered anaerobic systems can generate significant amounts of odors and renewable energy in the form of methane. The sulfides and methane are lost to the atmosphere due to lack of an impermeable barrier. If the basins were covered, the biogas could be captured, burned and converted to electricity and odors contained. A Missouri project, believed to be the largest and most ...

  • Algal biofuels from wastewater treatment high rate algal ponds

    This paper examines the potential of algae biofuel production in conjunction with wastewater treatment. Current technology for algal wastewater treatment uses facultative ponds, however, these ponds have low productivity (∼10 tonnes/ha.y), are not amenable to cultivating single algal species, require chemical flocculation or other expensive processes for algal harvest, and do not provide ...

  • Case study - Wastewater lagoon cover stops odor complaints

    Problem: United Liquid Waste Recycling (ULWR) successfully recycles food and beverage waste into valuable by-products such as fertilizer. Odors from their anaerobic treatment process needed to be stopped to enable ULWR in Watertown Wisconsin to expand. Their two lagoon anaerobic digesters needed an affordable system to control odors. ULWR injects their valuable fertilizer into farm fields twice ...

  • Case study - Floating covers reduce TSS, improve chlorine disinfection

    Problem: Algae and ultraviolet (UV) rays were adversely affecting chlorination in an upstate New York reservoir and Southern Florida WWTF. Algae was shielding embedded bacteria from chlorine, making the bacteriacide ineffective, thus requiring the chlorine dosage to be increased. Algae increased the chlorine demand along with exposure to UV which dissipates un-stabilized chlorine. Both ...

  • Conceptual analysis of the UASB/polishing pond system regarding the removal of surfactants, micropollutants and control of gaseous emissions

    A conceptual and integrated analysis of the UASB/Polishing Pond system is presented in relation to the removal of specific constituents not normally covered in the pond's literature, namely surfactants (linear alkylbenzene sulphonate, LAS), micropollutants (phthalates and bisphenol A) and sulfide. Experimental studies carried out on a small full-scale UASB/PP system have shown limited overall ...

  • Performance comparison between two equal stabilization ponds operating with and without sludge layer

    Stabilization ponds are a highly appropriate system for treating sewage in small to medium size communities. However, sludge accumulation at the pond bottom occurs with the passage of time, reducing the net pond volume, which, in principle, could affect its performance. The objective of this paper is to compare the behaviour of two equal ponds in parallel treating the same flow of municipal ...

  • 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 ...

  • Tropical stormwater nutrient degradation using nano-TiO2 in photocatalytic reactor detention pond

    The photo-degradation of nutrients in stormwater in photocatalytic reactor wet detention pond using nano titanium dioxide (TiO2) in concrete was investigated in a scale model as a new stormwater treatment method. Degradation of phosphate and nitrate in the presence of nano-TiO2 under natural ultra violet (UV) from tropical sunlight was monitored for 3 weeks compared with normal ponds. ...

  • Relating Land Cover Characteristics and Common Loon Mercury Levels Using Geographic Information Systems

    This effort models the relationship between mercury (Hg) levels in the common loon (Gavia immer) and land cover types as defined by the National Land Cover Database (NLCD). We constructed the model within the framework of a GIS to analyze the spatial relationships between land cover types and blood Hg levels in male common loons. Thiessan polygons were used to generate the territory for each ...
