Nitrification processes in scrubbing liquid of an exhaust air treatment system of a large-scale pig housing facility
The use of multi-staged exhaust air treatment systems is an effective method of substantially reducing the emission of ammonia, dust particles and odorous substances. Wet filter walls are able to absorb large amounts of ammonia when scrubbing fluid containing sulphuric acid is used. In addition, due to their large surface areas and the permanent supply of oxygen and nutrients, wet filter walls ...

Characterization of microbial communities in exhaust air treatment systems of large-scale pig housing facilities
Exhaust air treatment has gained importance as an essential factor in intensive livestock areas due to the rising emissions in the environment. Wet filter walls of multi-stage exhaust air treatment systems precipitate gaseous ammonia and dust particles from exhaust air in washing water. Microbial communities in the biomass developed in the washing water of five large-scale exhaust air treatment ...

BBK bio airclean removes obnoxious smell at Ribe Biogas - Case Study
During the expansion of the biogas plant, Ribe Biogas, BBK bio airclean was chosen as supplier of the new odour removal system. Ribe Biogas was established in 1990 and was originally the largest thermophilic plant in the world and for many years it demonstrated a stabile production and high degree of operational reliability. The biogas plant has expanded several times and was ready to double ...

The latest information about scrubber installation
IMO 2020 marine fuel regulations result in “very long waiting lists at some shipyards,”, especially in China, for scrubber installation on ship vehicles. The thing is that wet air scrubbers are made to order, and their manufacture generally takes about six months. After the creation, the wet scrubbers are held by shipyards, where queues for installation have now built up. It should ...

Common Treatment Technologies for Nonhalogenated VOCs in Ground Water, Surface Water and Leachate
It may be necessary to know other subsurface information to provide remediation of VOCs in the ground water. Treatability studies to characterize the biodegradability may be needed for any biodegradation technology. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be ...

Project - Excel Linen Supply - Kansas City, KS
Excel Linen Supply in Kansas City is the largest supplier of linens to the food and beverage industry in Kansas City and surrounding areas. After relocating their plant they were faced with very high waste water surcharges. They already had in place a Kemco DAF (Dissolved Air Flotation System) as their main treatment process. This system kept Excel in compliance with the local waste water ...

Measuring enthalpy to calculate efficiency
Summary This application note describes in detail how you can calculate the gain in efficiency of a direct exchange air conditioning system before and after treatment with the SRA. The physics underlying the method are explained. Introduction Air comprises gasses and water moisture. The gasses are mostly nitrogen (78%) and oxygen (21%). The amount of water moisture in the air is expressed as a ...

Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate
It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

Raynesway resource park - Case Study
The Raynesway Resource Park is a 35 hectare site bounded on three sides by the River Derwent. The southern half of a former chemicals plant, soils and groundwaters were impacted by chlorinated solvents, acid tars, hydrocarbons and ammoniacal sludges. Celtic designed a sophisticated groundwater treatment system, integrating air sparging, multi-phase extraction and chemical oxidation to address ...

Common Treatment Technologies for Nonhalogenated VOCs
Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

Refinery remediation: fuel recovery and recycling
Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

PEWE Odom's Tennessee Case Study
Facilty Background The Odom’s Tennessee Pride Little Rock facility inherited an aging undersized wastewater treatment dissolved air flotation (DAF) system. The old DAF aeration system needed replacing to create the 20-30 micron bubbles necessary for effective solids removal. The DAF pump was a centrifugal design producing large bubbles. These bubbles disturbed the sludge blanket that did ...

Acid Gas Removal Unit
What is acid gas? Very strictly speaking, an acid gas is any gaseous compound that forms an acidic solution when dissolved in water. While there are many types of acid gases, the most prevalent are carbon dioxide (CO2) and hydrogen sulfide (H2S). These chemicals are commonly found in natural gas deposits but render the gas unusable. They are not toxic when they come into contact with people, they ...

Used Furnaces & Ovens
Industrial ovens and furnaces are both heated chambers used to process raw materials at higher temperatures than what can be obtained in open-air systems. There is a range of heat treatments possible with both industrial furnaces and ovens, and the main purpose of any heat treatment is to change the mechanical of physical properties of a material. Some examples of materials that benefit from ...

Air sparge system - Case Study
ERC was contracted to install an air sparge system in Central Ohio. Air sparging is an in situ remedial technology that reduces concentrations of volatile constituents in petroleum hydrocarbons adsorbed to soils and dissolved in groundwater. This involves the injection of contaminant-free air into the subsurface saturated zone, enabling a phase transfer of hydrocarbons from a dissolved state to a ...
