  • Biological nitrate removal using waste-derived extracts as sole carbon source

    Waste-derived multicomponent extracts were investigated as carbon source for biological nitrate removal. Aerobic and anaerobic sludge from a municipal wastewater treatment plant and leachate from an anaerobic digester treating food waste were studied. Alkaline-heat treatment was used for sludge solubilisation. More than 90% carbon was recovered at pH 10–11. The extracts contain very high ...

  • Full‐life chronic toxicity of sodium salts to the mayfly Neocloeon triangulifer in tests with laboratory cultured food

    While insects occur in nearly all freshwater ecosystems, few sensitive insect models exist for use in determining the toxicity of contaminants. The objectives of the present study were to adapt previously developed culturing and toxicity testing methods for the mayfly Neocloeon triangulifer (Ephemeroptera: Baetidae), and to further develop a method for chronic toxicity tests spanning organism ...

  • Evaluating Food Digestion Effluent For Landscape Use

    Over the last year, Loyola Marymount University (LMU) has installed and studied a food waste diversion technology that converts raw food waste into a liquid effluent that is disposed through the sewer system. As an urban university located in West Los Angeles, California, LMU faces two major barriers with respect to composting food waste: on-campus space constraints and long distances to off-site ...

  • International Journal of Soil, Sediment and Water features `new field test for lead in soil` article

    ABSTRACT Field tests for the detection of lead in soil are not frequently accepted, since the tests are rather cumbersome or not reliable for screening determinations. Recently, we developed the LEADQuick field test kit for the detection of lead in water with 3 #22;g/L sensitivity. This test is further modified to detect lead in soil with a sensitivity 0.03 #22;g. We developed an extraction ...

  • Recycling of Urban Sewage through cladoceran culture system

    The feasibility of using Urban Sewage (US) was tested in static water holdings for the culture of Daphnia, a cladoceran that is used as a live fish food. US was diluted to 60% (D40), 50% (D50), 40% (D60) and 30% (D70) by adding normal freshwater to constitute a total volume of 15 litres. Each culture medium (in triplicate) was inoculated with four units of Daphnia sps. per litre. The population ...

  • Success of Onlin Leads to Closing for Wastewater 2 Process Control of Consent Order Treatment Plant

    In 2003, Plant City, a small Florida city of 30,000 residents, faced a very big problem. The Florida Department of Environmental Protection (FDF.P) determined that the city's wastewater treatment plant was not consistently operating within its permit limits, and placed it under a consent order. Plant City is a highly industrialized area. "Our industrial loading is very diverse and includes metal ...

  • Give Your Denitrification Bugs a Sugar High

    ABSTRACTAn alternative substrate to methanol was sought for tertiary denitrification. High fructose corn syrup (HFCS) was identified as the most cost effective alternative, which would also be much safer to handle. This should also render HFCS subject to less legislation at all levels of government. A pilot scale test was conducted. The test confirmed that HFCS is a suitable substrate. A dose of ...

  • Analysing four of the most contaminated foodstuffs

    Food adulteration has been around since the Victorian times when cheese was often coloured with lead salts, beer and milk were watered down and flour was bulked out with chalk dust or ground bones [1]. Governments apply stringent legislation and quality standards to food products but the practice of adulteration, driven by greed and profit, is still seen. ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...

  • 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 ...

  • Enhanced Anaerobic Bioremediation of a TCE Source at the Tarheel Army Missile Plant Using EOS

    EOS, or emulsified oil substrate, was used to stimulate anaerobic biodegradation of trichloroethene (TCE) and tetrachloroethene (PCE) at a former Army-owned manufacturing facility located in the Piedmont area of North Carolina. Previous use of chlorinated solvents at the facility resulted in soil and groundwater impacts. Ten years of active remediation utilizing soil vacuum extraction and air ...

  • The Use of Hydrogen Release Compound (HRC) for CAH Bioremediation.

    Hydrogen Release Compound (HRC™) is a simple, passive, low-cost and long-term option for the anaerobic bioremediation of chlorinated aliphatic hydrocarbons (CAHs) via a reductive dehalogenation pathway. Applications to other classes of chlorinated compounds that are anaerobically degradable by this mechanism are under investigation. HRC should be viewed as a tool for the enhancement of natural ...

  • Analysis of monitoring results of the separation and greywater treatment system at Chester Woods Park, Olmsted County, Minn.

    Introduction In 1993, Olmsted County installed an advanced individual sewage treatment system (ISTS) at the caretaker's residence at a County-owned park to demonstrate waste load reduction and downsizing of drainfield area. The subject system has two components--1) a composting/vermiculture blackwater system and a 2) aerobic graywater treatment system. The separation of the high strength ...
