  • The Effect of the Microsludgetm Treatment Process on Anaerobic Digestion Performance

    ABSTRACT Thickened waste activated sludge (TWAS) from biological treatment processes is less amenable to anaerobic digestion than primary sludge. This is due to TWAS being composed mostly of cellular material and extracellular polymeric substances (EPS) instead of more easily digestible carbohydrates and fats that are typically found in primary sludge. In an attempt to improve TWAS digestion ...

  • Integrated Anaerobic and Aerobic Processes for Treatment of Municipal Wastewater

    ABSTRACTIn this study, integrated anaerobic and aerobic treatment processes for municipal wastewater treatment were investigated for its feasibility to replace the existing conventional activated sludge process. Three types of anaerobic systems − anaerobic sludge blanket, anaerobic sequencing batch reactor and anaerobic filter, as the pretreatment step were studies. High solids and organics ...

  • Bio-desulfurization and denitrification by anaerobic-anoxic process for the treatment of wastewater from flue gas washing

    For amine-based carbon dioxide capture, nitrogen oxides and sulfur oxides were the main pollutants that had a negative effect on the regeneration of solvent. Before carbon dioxide capture, the sulfur oxides in flue gas should be removed by the method of calcium salt, and then washed by alkaline solution to eliminate the residual nitrogen oxides and sulfur oxides. The washing wastewater ...

  • Pilot scale evaluation of SANI® process for sludge minimization and greenhouse gas reduction in saline sewage treatment

    This study reports on a pilot trial of the SANI® process (Sulfate reduction, Autotrophic denitrification and Nitrification Integrated process) in Hong Kong. A pilot-scale SANI plant treating saline sewage at 10 m3/day was scaled-up from a lab-scale system treating synthetic saline sewage. The plant consisted of a sulfate reduction up-flow sludge bed (SRUSB), an anoxic bioreactor (BAR1) for ...

  • 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 ...

  • Case study - Amine tail gas treatment

    COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time ...

  • 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 ...

  • 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 ...

  • Allweiler pumps in exhaust gas treatment systems in ships

  • Modeling Greenhouse Gas Emissions From Activated Sludge Processes

    Dynamic simulation of activated sludge process is a common tool for wastewater treatment design and optimization. Most activated sludge models predict only the uptake of BOD and nutrients, however, they can easily be supplemented with further information regarding greenhouse gas (GHG) production to predict the generation of components such as CO2. Many published anaerobic digestion models contain ...

  • Applications of the deep-shaft activated sludge process in wastewater treatment

    The deep-shaft activated sludge process is a unique modification of the activated sludge system. The main objective of this system is to increase the amount of dissolved oxygen available for biological activity. This can be achieved by increasing the rate of oxygen transfer from the gas phase to the liquid phase. The deep-shaft configuration increases the partial pressure of oxygen, thereby ...
