  • Performance of soil and compost mixture in leachate purification at intermediate cover soil of tropical landfill

    Leachate treatment was studied in simulated columns filled with different types of cover materials, i.e. (a) natural soil, (b) mixture of soil and planting soil, (c) mixture of soil and compost at 2:1 ratio and (d) mixture of soil and compost at 1:1 ratio. Filter performance was evaluated at different water application rates equivalent to rainfall intensity of 25, 50 and 100 mm/d. Leachate ...

  • Hydraulics stability of compost-based filtration media

    The longevity of compost-based storm water filtration systems has not been widely studied. Hydraulic conductivity measurements of compost amended sand media (20% and 50% v/v) within columns were undertaken. The results show that the filtration media in both columns had a reduction in the total saturated hydraulic conductivity. A tracer test showed there was no blockage due to biological or ...

  • Elimination of NH3 and odor from composting by biotrickling filter and preliminary exploration on molecular biology

    A biotrickling filter was focused on treatment of odorous NH3 gas, along with volatile organic compounds (VOCs) and other odorous gases during cattle manure composting. The biotrickling filter could treat NH3, the main composition, with removal efficiencies of close to 100% because NH4+ was bio-oxidized in the biofilm to NO3− resulting final NO3− concentrations of about 1000 mg/L. Results of ...

  • Residence time and contact volume in sloped compost and compost/vegetated filter beds

    Little is known about transport mechanisms in sloped dormant vegetated and compost only filters for roadway runoff. Residence time experiments were carried out in triplicate in 0.254 m wide × 0.65 m long by 0.10 m deep beds using a bromide tracer. Bed slope was 12°. Only at the lowest flow rate tested (0.276 l/min per m of filter width) were mean residence times in compost beds with and without ...

  • Biosolids Composter Satisfies Customers and Neighbors

    A ticket to Penn State football games isn’t the only hard thing to come by in State College, Pennsylvania. So is the biosolids compost produced by State College’s University Area Joint Authority (UAJA) wastewater treatment plant. “For the last four years, we’ve been sold out before we’ve made the compost,” says Stephen Welch, who manages the UAJA composting plant. All biosolids generated — about ...

  • Biotretment of polluted air of a storage for used plastics in bio-trickling filter (BTF)

    The problem High concentrations of unhealthy sporogenic funghi and bacteria in malodorous gases of a used plastic storage could not be purified by classical compost filters, because of their high emissions of microorganisms. Problem solution By indoor-biofiltration in a bio-trickling filter using microbially activated LEVAPOR carrier the polluted air has ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • The use of sewage sludge compost for improving reedbeds performance

    In a wastewater of medium strength, about 75 % of the suspended solids and 40 % of the filterable solids are organic in nature. The parameter used for measuring the strength and the quantity of the organic substances in the wastewater is the Chemical Oxygen Demand (COD) (Aggelakis and Tchobanoglous, 1995; Tchobanoglous and Burton, 1991). Degradable organic matter in wastewater, whether soluble or ...

  • Longer Life For Biofilters

    Biofilters are the odor control system of choice at composting facilities. Despite similar capital costs, the biofilters are generally less costly to operate than chemical scrubbers. The key to keeping operating costs in check, however, is to get the maximum use out of the biofilter media, thus avoiding the time and money needed to do media replacements. Allen Boyette, senior engineer and manager ...

  • Springfield - Case Study

    At Their Disposal Komline-Sanderson minimizes solid waste disposal costs in Springfield, Mass The City of Springfield, Mass., currently uses a contract composting facility, which is located at the 65 MGD Bondi Island Wastewater Treatment Plant to dispose of their solid waste. The composting facility requires a feed of 40–45% solid materials to ...

  • CO2 monitoring for Sustainagro - Case Study

    Challenges the customer faced According to former development manager for Sustainagro, Adrian Parker, before the lab had the G100 and could measure in real-time it used a titration method: "It took ages, several hours, just to do one." How the product helped The G100 has made the process much quicker; the lab can have several different flasks and ...

  • Regional roundup

    Ithaca, New YorkCOMPOSTING PET WASTE AT DOG PARKCayuga Compost and Tompkins County Dog Owners Group launched a program on Earth Day this year to collect and compost pet waste at the Ithaca Dog Park. About 5,000 bags are used to collect 1,000 pounds of dog waste every month at the park. Plastic bags were previously provided by Wegmans supermarket, and disposed of in dumpsters going to ...

  • Wood, Yard Trimmings Recycler Grows by Heaps and Bounds

    GRIND-ALL has been in existence - in one form or another - since 1992. Originally owned by Paul Robins, and operated under the name East Coast Wood Recycling, the company, based in Mosely, Virginia near Richmond, was solely focused on selling wood products at the wholesale level. Three years later Robins joined forces with Robbie Urbine, whose expertise in retail sales allowed the company to open ...

  • Saturated and unsaturated flow through sloped compost filter beds of different particle sizes

    Little is known about the hydraulics of sloped compost beds having active free and non-flowing zones, and used for runoff erosion and volume control, and heavy metal removal. Water sorption tests on yard waste compost indicated that water transfer between the two zones would be slow (6 hr for a 0.04 m rise). The free flowing zone in ≈1 m long sloped (15°) beds increased in depth ...

  • Building soils for storm water compliance and successful landscapes

    THE SOILS for Salmon project - initiated in 1999 by the Washington Organic Recycling Council (WORC) - has been building momentum through collaboration with the Washington Department of Transportation (WSDOT), regulators at the state Department of Ecology, local governments, scientists, and green leaders in the building, landscape and development industries. Over the years, the Soils for Salmon ...

  • Biological Removal of Ammonia from Contaminated Air Streams Using Biofiltration System

    ABSTRACT Ammonia is a colorless, toxic, reactive and corrosive gas with a sharp odor. It is irritating to the skin, eyes, nose, throat, and lungs. Ammonia gas occurs in the environment naturally and is emitted by many industries and, therefore, its control is essential. Biofiltration is a new emerging technology that is being used as a control procedure. This study evaluates the use of a ...

  • Compost in the mix for storm water management

    Bioretention areas, also known as rain gardens, are increasingly being used to capture and treat storm water runoff from impervious surfaces such as roofs, sidewalks and parking lots. These landscaped areas often feature native plants installed in an engineered soil mixture that includes compost. “Bioretention areas or rain gardens are an attractive storm water Best Management Practice (BMP) ...

  • Country Club Stream, Bank Stabilization - Case Study

    Akron, Ohio Worked with engineers and landscaping firm to repair country club stream on holes 4 and 10 that were damaged by a volatile adjacent stream. We used matting to ensure the surrounding area was not damaged by our equipment as we excavated and widened the creek. Stream restoration, we rebuilt the channel and waterfall using placed rock and added j-hooks and v-weir structures ...

  • Studies on Biofiltration of Contaminant Mixtures

    Most gaseous emissions from waste water treatment plants, industrial operations, and solids handling facilities, consist of contaminant mixtures rather than pure chemicals. In the literature, several studies have been conducted on biological treatment of gaseous emissions using either naturally bioactive media (soil, peat, compost, etc.) in biofilters or synthetic support media in biotrickling ...
