  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • 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 ...

  • 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 ...

  • Ultrasonic Waste and Sludge Treatment

    Biogas is generated from sources, such as municipal organic waste, sewage sludge, muck or manure. Ultrasonication improves the digestibility of such organic material leading to more biogas and less residual sludge. Biogas is a byproduct of the decomposition of organic matter by anaerobic or aerobic bacteria. It consists primarily of methane, carbon dioxide and hydrogen sulfide. This makes biogas ...

  • Biofiltration systems for the treatment of waste gas from industrial plants

    Bord na Móna Environmental Ltd have considerable experience in the field of biological air filtration (600 installations). Initially, the majority of installations were on Municipal and Industrial Wastewater applications. This was quickly followed by Municipal Solid Waste, an application Bord na Móna jointly developed with its Italian partners Air Clean srl. Since 2000, Bord na Móna have ...

  • Centralised treatment of oil sludge and other industrial waste

    Centralised treatment of various sources of industrial waste has been established in many European countries over the last decade. Many facilities are still equipped with non state of the art technology and therefore cannot fulfil the broad field of applications with regard to industrial waste remediation. econ's international client decided to be one step ahead and erected a new econ industries ...

  • 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 ...

  • Anaerobic treatment of food waste in pilot scale

    For this work, a pilot scale anaerobic digester was used to assess the treatability of food waste from a canteen. The digester was operated for 720 days, and its efficiency in removing organic matter and suspended solids as well as producing biogas were assessed. At the beginning of operation, the digester failed and alkalinity buffering was required until stabilization. A maximum chemical ...

  • Online Odors Monitoring in Waste Water Treatment Plants

    Odors are very distinct air contaminants as they generate nuisances (see note at the end). The factors playing a role in the determination of odor annoyance are : odor concentration and intensity, frequency, appreciation, duration, synergy and location. Chromatotec proposes an automated solution to well identify the origin and the level of odors. Technology Description We offer a ...

  • In-Situ thermal treatment of MGP waste and creosote

    Abstract: Remediation of coal tar at former Manufactured Gas Plant (MGP) sites, and creosote associated with wood preservative sites is challenging due to the viscous nature of the dense non-aqueous phase liquid (DNAPL) and the modest solubility and vapor pressure of the contaminants of concern (COCs). DNAPL seepage into surface water bodies, as well as groundwater plumes formed by the most ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...
