  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • The next generation biological odour control systems

    Odour is usually caused by the presence of hydrogen sulphide, mercaptans (Organic sulphur components) and ammonia, but also multiple other VOC’s (volatile organic compounds) bringing numerous odour complaints at e.g. WWTP’s, pumping stations and composting plants. An odour control system therefore will have to treat not only hydrogen sulphide, but also other pollutants to reduce the total ...

  • 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, ...

  • Slurry Phase Biological Treatment

    Slurry phase biological treatment involves the controlled treatment of excavated soil in a bioreactor. The excavated soil is first processed to physically separate stones and rubble. The soil is then mixed with water to a predetermined concentration dependent upon the concentration of the contaminants, the rate of biodegradation, and the physical nature of the soils. Some processes pre-wash the ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...

  • Significant Improvements in Biofilter Performance for H2S and VOC Removal Using Biotrickling/Bioscrubber Technology in the Aeration Distribution Plenum System

    ABSTRACT Biofilters can handle the removal challenge of a diverse mix of complex odors and VOCs. However, there are significant limitations in handling levels of hydrogen sulfide (H2S) loadings above 10 ppm. High levels of H2S loading in biofilters will create an increase in the acidithiobacillus colony causing an overproduction of acid. This will destroy all other biodegrading ...

  • The Benefits of an Integrated Air and Water Pollution Control Partner

    Although there has been substantial progress during the past several decades in reducing pollution, the EPA, other federal agencies and local governments continue to add and revise requirements and standards, making compliance a challenge for the industrial sector. These companies also face increasing public pressure not just to meet but to exceed pollution control standards, as studies continue ...

  • On the ionization of air for removal of noxious effluvia” (Air ionization of indoor environments for control of volatile and particulate contaminants with nonthermal plasmas generated by dielectric-barrier discharge)

    Abstract Recent developments in the application of controllable air ionization processes that apply dielectric-barrier discharge devices to generate nonthermal plasmas have led to applications for chemical and biological decontamination in indoor air environments. These include significant reductions in airborne microbials, neutralization of odors, and reductions of specific volatile ...

  • Biofiltration systems for the treatment of waste gas from industrial plants

    Bord na Móna Environmental Ltd have considerable experience in the field of biological air filtration (600 installations). Initially, the majority of installations were on Municipal and Industrial Wastewater applications. This was quickly followed by Municipal Solid Waste, an application Bord na Móna jointly developed with its Italian partners Air Clean srl. Since 2000, Bord na Móna have ...

  • Innovative Uses of Compost Bioremediation and Pollution Prevention

    Each year agricultural effluents, industrial residues, and industrial accidents contaminate surface waters, soils, air, streams, and reservoirs. A new compost technology, known as compost bioremediation, is currently being used to restore contaminated soils, manage stormwater, control odors, and degrade volatile organic compounds (VOCs). Compost bioremediation refers to the use of a biological ...

  • Indoor air quality can be improved by employing plants as walls

    The practice of planting ivy to climb up the walls of buildings has existed for centuries. Now, the trend towards sustainability and green building practices can lead to the development and use of living walls as a means of filtering and improving a building’s indoor air quality. Green walls are a living, breathing, regenerating type of cladding that can be as simple as a living art installation ...

  • Electrical Resistance Heating: a Hot New Approach to Soil and Groundwater Remediation

    Electrical Resistance Heating (ERH) is an aggressive remediation technology that can quickly reduce the mass of volatile organic compounds (VOCs) in soil and groundwater by over 99%. The process is often used to clean sites where other technologies have had limited success. Larger ERH sites are cleaned within 6 to 12 months and smaller sites can be cleaned in half that time or ...

  • Case Study: Odor Abatement Solutions

    Odor issues related to industrial processes are not uncommon.  An odor is caused by one or more volatilized organic compounds (VOCs) that humans can perceive by the sense of smell.  The challenge is that “odor is subjective, and what is sweet to some, can be a nuisance to others.   In most cases the ...

  • 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 ...

  • Bord na Móna introduces new wastewater technologies

    Bord na Móna Environmental Products U.S. Inc., the American market subsidiary of the $550-million Bord na Móna group based in Dublin, Ireland, introduced three new wastewater treatment solutions and new odor/VOC control technologies at WEFTEC.08 in Chicago, Ill. The company said it was significantly expanding its commitment to the U.S. market through the ongoing development of environmentally ...

  • Landfarming

    Introduction Landfarming is a full-scale bioremediation technology, which usually incorporates liners and other methods to control leaching of contaminants, which requires excavation and placement of contaminated soils, sediments, or sludges. Contaminated media is applied into lined beds and periodically turned over or tilled to aerate the waste. Soil conditions are often controlled to ...

  • Five Additional Technologies Evaluated After ERH Application at Camp Lejeune

    Groundwater at Site 89 of Marine Corps Base Camp Lejeune in North Carolina is contaminated with two dense non-aqueous phase liquid (DNAPL) plumes and a large dissolved plume. The Navy took a phased approach over the past six years to address each of these components. In 2003, electrical resistive heating (ERH) was evaluated in a pilot study to treat one DNAPL plume. In 2006, field-scale ...
