  • 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 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 ...

  • 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 ...

  • Waste Water Treatment Plants

    In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within ...

  • Reductions in greenhouse gas (GHG) generation and energy consumption in wastewater treatment plants

    Greenhouse gas (GHG) emission and energy consumption by on-site and off-site sources were estimated in two different wastewater treatment plants that used physical–chemical or biological processes for the removal of contaminants, and an anaerobic digester for sludge treatment. Physical–chemical treatment processes were used in the treatment plant of a locomotive repair factory that ...

  • Ethylene Plant Treatment Hydrocarbon Engineering

    Ethylene is the most commonly produced petrochemical product. The bulk of annual commercial ethylene production is based on thermal cracking of hydrocarbon feedstocks with steam. Usual raw materials for pyrolysis are refinery gas, liquid petroleum gas (LPG), natural gas liquids (NGL), naphtha or gas oil. The production of ethylene is a very complex process, including cracking, cooling, ...

  • Nimr Water Treatment Plant Oman

    Introduction The Nimr water treatment plant (NWTP) project is located in the south of Muscat in Oman. The temperatures in the region can be as high as 60°C in the summer months, making it a harsh environment to work in. This water treatment project was co-executed by Bauer Environment and Petroleum Development Oman (PDO). The plant came online in late 2010 and has been treating ...

  • Carbon footprints of Scandinavian wastewater treatment plants

    This study estimates the carbon footprints of 16 municipal wastewater treatment plants (WWTPs), all situated in Scandinavian countries, by using a simple model. The carbon footprint calculations were based on operational data, literature emission factors (efs) and measurements of greenhouse gas emissions at some of the studied WWTPs. No carbon neutral WWTPs were found. The carbon footprints ...
