As is the case for many industrial manufacturing processes, emissions are best destroyed through the use of thermal and catalytic oxidation technologies. Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) are destroyed through the use of high temperature combustion with direct heat recovery. The harmful air pollutants are converted to heat, water vapor and carbon dioxide, creating a destruction efficiency greater than 99%.
The United States Environmental Protection Agency (EPA) has two stack testing methods for FTIR gas analyzers. Method 320 is an FTIR method for measuring wide range of organic and inorganic pollutants. Method 321 is a specific version for measuring hydrogen chloride HCl at cement kilns producing Portland cement. These methods define a quality assurance and control processes for verifying the accuracy of the results. The requirements for analytical equipment and software are defined on 40 CFR Part 60 Appendix B...
Chemical product manufacturing involves the handling of acids, carcinogenic and toxic chemicals, along with the emission of fumes that contain volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and particulates.
UV, Ozone and Advanced Oxidation Technologies are innovative approaches to safely disinfecting and destroying organic pollutants in water, industrial waste waters, ground waters and gas effluents. These processes do not simply transfer pollutants to other mediums. Unlike other disinfection and oxidation techniques, UV, Ozone and advanced oxidation processes do not create toxic by-products. The ultimate end products of the advanced oxidation processes are carbon dioxide and water.
Removing Organic and Nitrogen Pollution: We all need water to survive. Yet there are many pollutants reducing the quality of the available resources. ENEXIO products are an indispensable part of many processes applied for the removal of those pollutants from the water. Surface water can be polluted by agricultural, industrial or municipal discharges of nitrogen (ammonia or nitrate) or even organic components. For the removal of these components biological processes are a valuable option – also for potable...
The analysis of volatile organic compounds at low concentration levels is fundamental to pollution monitoring and control.
Hiden’s Hydramass spectrometer is a multi-stream gas analysis system for analysis of volatile organic compounds to the sub ppm level.
In sea water the analysis of volatile organic compounds is used for both pollution monitoring and ecological studies.
Hiden’s HPR 40 dissolved species analyser provides ppb sensitivity
ULTRAAQUA UV systems are used for a tremendous number of different industrial applications. UV disinfection is typically preferred for internal processes such as fluid disinfection in food processing and cooling water disinfection. Externally for further cleaning of intake water (disinfection or degradation of organic pollutants) or for the waste typically as part of a wastewater treatment system in order to increase water reuse or to produce an environmentally safe fluid waste stream.
Traditionally, the Petrochemical Sector has operated with basic technological solutions, with ultimate reliance on High Temperature Incineration (HTI) and landfill in order to deal with their hazardous wastes. However, tightening regulation, increasing landfill costs and social responsibilities are driving companies to look at alternative methods of treatment of very challenging wastes, including the treatment of:
Chemical Oxygen Demand (COD) is used as a measure of organic pollutants in water. In wastewater treatment, it indicates the efficacy of a treatment process and is expressed in milligrams per litre (mg/L) or parts per million (ppm). Removing certain fractions of COD in waste streams can be particularly challenging, especially to levels safe for discharge to the environment.
Organic Micro-pollutants are low and trace levels of synthetic organic substances released in water through human activity. They can be found in industrial, agricultural and domestic wastewater streams. Some of the most difficult-to-treat wastewater contains micro-pollutants such as persistent organic pollutants (POPs), herbicides and pesticides, personal care products (PCPs), toxic chemicals, carcinogenic and endocrine disruptive compounds (EDCs), and emerging contaminants.
Indoor air quality has become as important as temperature and humidity when it comes to the preservation of valuable collections in modern metropolitan galleries, archives, libraries and museums. From the San Francisco Museum of Modern Art to Philadelphia’s Barnes Foundation, designers have used air cleaning technology from Dynamic Air Quality Solutions to provide clean, contaminant-free air to some of the most valuable collections in the world. Coast to coast and around the world, Dynamic has successfully...
The Natural Energy Solution uses a proprietary, patented process called Gas Phase Reduction (”GPR”). This is a highly effective, non-incineration method that converts all organic waste and destroys all hazardous organic waste products.
Biomass contains much more than just the energy of the future. Selected biogenic residues (SRC wood, silage waste, extract residues, paper fibre sludge…) can be refined into new, valuable products such as biochar, charcoal feed or activated carbon by carbonisation (charring). But even if the material can no longer be refined, you benefit from the carbonisation in the PYREG process.
Drain flies appear in homes, rest rooms of commercial buildings, sewage disposal plants and agricultural facilities that handle moist animal waste. Restaurants, schools and other public buildings may be avoided when drain flies are a nuisance. Bronchial asthma can be caused by inhaling fragments and dust of dead flies. Since these flies originate in filthy conditions, there is the possibility of physical transmission of microbes of human health concern. Drain flies can carry bacteria and other microorganisms from...
