Chemical Engineering Magazine: Odor Issues and Solutions for Wastewater Treatment

Today, there has been a dramatic increase in the number of industrial operations that are located within or near small towns and even large cities. When local residents constantly smell these industrial processes – particularly from wastewater treatment — unhappy neighborhoods are generally the result. In addition, many wastewater facilities can no longer produce odors without facing ...

Use of process analytics in cryogenic air separation plants – Case Study

For further treatment of primary and intermediate materials, large amounts of oxygen and nitrogen are required by many industries, e. g. chemical and petrochemical, metal, semiconductor and food industry, in machine construction and many others. Oxygen and nitrogen are, together with Argon, the main constituents of ambient air. They are obtained from there by means of the air separation ...

Air Emissions/Off-Gas Treatment

A number of technologies have been widely applied for removal of VOCs from off-gas streams. However, the application of these technologies to off-gases from site remediation may be quite limited. Biofiltration has been widely applied for VOC destruction in Europe and Japan, but it has only recently been used in the United States. Catalytic and thermal oxidation are widely used for the destruction ...

Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

Exhaust gas treatment by an atmospheric pressure microwave plasma

A microwave process for treating exhaust gases from internal combustion engines is presented. The exhaust gases are ionised by microwave energy at 2.45 GHz and the resultant plasma jet discharges into ambient air and exhaust gas environment. A gas analyser was used to measure the change in exhaust gas composition due to the influence of the plasma. Large decreases in CO2, CO and hydrocarbon ...

Greenhouse Gas Inventories and Wastewater Treatment Plants

ABSTRACT A greenhouse gas inventory identifies the sources and quantities of GHG emissions from a facility or a larger organization. Several best practice standards exist that provide guidance for conducting GHG inventories for industrial facilities like a WWTP. Key considerations in a WWTP GHG inventory will include emissions associated with thefacility’s energy use as well as methane ...

Liquid waste off-gas treatment - Case Study

Application Biffa Waste Services operate a major waste disposal site at Kilsyth in Scotland where they handle many types of industrial liquid effluent. This can give rise to a range of emissions from both the tank farm and the road tanker deliveries. In addition, significant NO2 and nitric acid fume releases can arise from process upset conditions. ERG provided an emergency NO2 ...

A Four Channel Gas Detector for Wastewater Treatment Plants

Common hazardous gases found in wastewater treatment plant facilities are hydrogen sulphide, methane, ammonia, carbon monoxide, chlorine and oxygen deficiency. Some facilities may also use ozone, chlorine dioxide or sodium hypochlorite with the chlorine during the sanitization treatment process. Furthermore, sulphur dioxide is often used to de-chlorinate the water once the treatment process is ...

Wastewater treatment for mining camps/oil and gas camps

Mining and oil and gas camps operating in remote and environmentally sensitive areas become home to large work forces for extended periods of time. Supplying water for domestic use and treating large volumes of sewage and greywater can be a complex and expensive challenge. Improper wastewater treatment can lead to pollution of the surrounding ecosystems. Many jurisdictions have tightened ...

Treatment of Sugar Carbonatation Sludge for Reuse and Flue Gas Desulphurisation

In this work sugar refinery carbonatation sludge is treated in a pilot scale facility for two purposes: reuse in the carbonatation process, mixed with fresh calcium hydroxide, and flue gas desulphurisation. The sludge is first dried, and then calcinated in a batch kiln with a capacity of 100 kg, designed for the purpose. This process is potentially attractive for the sugar industry, since it can ...

Greenhouse gas emissions from sludge treatment reed beds

Sludge treatment reed bed systems (STRBs) are considered as an alternative technology for surplus sludge treatment. Organic matter is decomposed by various microbial reactions, resulting in gases such as CO2 and CH4 emitting into the atmosphere. The aim of this study is to investigate gas emission from STRBs. The static transparent chamber was adopted to measure gas emission; it allows ...
