  • On the Ground with Diesel Corrosion - Case Study

    When the EPA revealed the results of its study in July on the increasing presence of substantial corrosion in diesel fuel tanks, it proved that the problem is much larger than anyone anticipated. The facts are staggering: 83%of the diesel tank systems exhibited moderate-to-severe corrosion. 75%of the owner/operators of those diesel tanks had no idea it was ...

  • The Evolution of Collector Monitoring Systems

    The vast majority of chain and flight collectors in operation throughout the world do not have any form of monitoring system installed to protect against operational failure. Traditional safety devices consist of a shear pin sprocket device, with a limit switch, designed to protect the drive system if a load or torque exceeds the working load of the  ...

  • Monitoring once through cooling water - Case study

    The Situation Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil.  These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often ...

  • Application notes: The Sievers InnovOx TOC analyzer: boiler water monitoring

    Background A boiler system is a semi-closed loop system in which water is heated and converted into steam to power a generator. The steam is then allowed to form a condensate and the process is repeated. Boiler water chemistry directly impacts boiler efficiency and fuel use. Improper water treatment allows scale formation and corrosion. Boiler scale and deposits form when impurities ...

  • Online Process Analyzer Installed at F.J. Horgan WTP to Monitor Chloramination

    Construction was completed on the City of Toronto's F.J. Hor-gan Water Treatment Plant in 1979, more than 60 years after chloramine had first been used to disinfect drinking water in an Ottawa plant. By then there was little debate about the benefits of chloramination and it was incorporated into the new plant's design as part of the disinfection process. Chloramine is more stable than free ...

  • Treatment plant protected by effluent monitor at major drinks factory

    The installation of a BioTector continuous TOC (Total Organic Carbon) monitor to police the front end of Cobevco’s wastewater treatment plant has enabled tight control of the treatment process. Delivering results 20 times faster than laboratory techniques, the monitor at the Elton facility in Cheshire provides advance notice of organic overload so that the plant is able to instantly divert ...


  • Challenges in addressing variability of lead in domestic plumbing

    Current data indicates that lead exposure is of concern even at low concentrations. Corrosion is an important problem in drinking water because it can affect public health due to leaching of lead or other metals into the drinking water. For this reason, a corrosion control program is an important measure to help mitigate exposure to lead in drinking water. The biggest challenge that remains in ...

  • Containment for Ground Water, Surface Water, And Leachate

    Containment measures are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards ...

  • Gas Detection in Public Swimming Pool Facilities

    Recreational facilities’ indoor swimming pools provide a venue for exercise, competition and fun for all ages as patrons splash, swim, dive and float around in the crystal clear water. To keep the water fit to swim in requires a disinfectant maintenance program commonly using Chlorine, or Chlorine and Ozone. Chlorine is a powerful, corrosive disinfectant and in both gas and liquid forms it ...

  • Pearl river valley water supply district case study

    Performance History and Discussion In-Pipe Technology implemented the first phase of a collection system Professional Services Program in 2001. Beginning in 2002, additional collection system basins were added to the services program. Currently, the treated areas include the North and South shore of the Pelahatchie Bay, the Main Harbor, and two Lagoon Waste Water Treatment Plant (WWTP) ...

  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

  • Microbes in oil E&P

    The role of microbes in the oil industry, both detrimental and beneficial, has now become more and more accepted. Reservoir souring and microbial influenced corrosion cost the oil and gas business millions of dollars every year, and require adequate mitigation and surveillance strategies. Monitoring using modern molecular microbiological methods has facilitated a better understanding of ...

  • Aminomethylphosphonic acid (AMPA) has low chronic toxicity to Daphnia magna and Pimephales promelas

    Aminomethylphosphonic acid (AMPA) is the simplest member of a class of compounds known as aminomethylenephosphonates and the only environmental metabolite measured in significant amounts during the degradation of the herbicide glyphosate in soil. However, there are additional sources of AMPA in the environment, originating from organic phosphonates which are used in water treatment to inhibit ...

  • CO2 adsorption over ion-exchanged zeolite beta with alkali and alkaline earth metal ions

    The need to reduce anthropogenic CO2 emissions has been the driving force to consider new approaches and novel ideas for CO2 management, and carbon capture and storage (CCS) are considered to potentially be the most effective means to alleviate the problem. The most common method for CO2 capture is via gas absorption, with monoethanol amine (MEA) being the most widely used solvent. The current ...

  • The importance of maintaining your fixed gas analyser

    Plant technicians rigorously check for contaminates within the digester and ensure that the performance is optimised but maintaining the gas analyser monitoring the whole process is often overlooked.  Many analysers are used in harsh and potentially explosive environments and so it is of paramount importance that the operation runs smoothly and safely. With simple maintenance of your ...

  • 1700 miles of the keystone Xl Pipeline: A state, federal and international regulatory concern
