    Monitoring Raw Water Intake

    The Situation: Hydrocarbons in water intake used for municipal drinking water and desalination systems are commonly limited to 1 part per million. Problem: Naturally occurring organics in raw water are typically treated with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when some type of organic material is present but cannot differentiate between natural organics, such as algae or leaves and hydrocarbons. Solution: A fluorescence monitor can be configured for sensitivity to hydrocarbons, with no significant response to other organics. The TD-4100XDC has the highest sensitivity to hydrocarbons in raw water, has a low cost of ownership, and can be modified with Teflon, Monel, and other corrosion resistant materials for sea water environments.

  • Moisture Monitoring for Liquid Benzene Feed Stock

    Moisture needs to be measured in feed stock gases in the manufacture of polymers . For example, pre-dried benzene is fed in to a reactor containing hydrochloric acid – if the dryers are not operating properly moisture in the benzene promotes acid corrosion of the reactor and process lines. Several processes require water concentrations of specific values to optimise efficiency and yield; in such cases more sophisticated instruments are required.

  • Pipeline Monitoring Systems for Health Monitoring

    Pipeline management presents challenges that are quite unique. Their long length, high value, high risk and often difficult access conditions require continuous monitoring as well as an optimization of maintenance interventions. The main concern for pipeline owners comes from possible leakages that can have a severe impact on the environment and put the pipeline out of service for repair. Leakages can have different causes, including excessive deformations caused by earthquakes, landslides or collisions mobile objects, corrosion, wear, material flaws or third party intrusion.

    Waste water treatment plants Air quality control by TRS MEDOR Online Odor Monitoring

    ontext & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. Odors are very distinct air contaminants as they generate nuisances. 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 automatic solution to well identify the origin and the level of odors.

  • Moisture Monitoring for Nuclear Reactors

    The Advanced Gas Cooled Reactor uses carbon dioxide gas to transfer heat from the nuclear fission core to the water boiler for steam generation. The moisture content needs to be monitored to avoid corrosion damage, and continuous moisture monitoring acts as a boiler leak detector or bulk moisture meter.

    Waste water treatment plants Personnel Safety & H2S filter management

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and Methylmercaptan increased. Safety of employees on such working sites has therefore become of major problem. To fight this hazardous pollution, air filtering systems have been installed. For the station managers, personal safety coupled with the need for constant air quality control and filter change has been a heavy task.

    Waste water treatment plants Screening area: stripping

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. To ensure the safety of operatives in the screening building/area of waste water treatment works an H2S analyzer has been installed in the main building to complement the protection provided by individual monitors. Chromatographic measurements show that other sulfurous compounds including Methylmercaptans are present in the air in addition to H2S.

These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. At the entrance of the waste water plants, where the waste water arrives, strongly smelling and polluted air is captured and neutralised by a chemical cleaning process called ‘’Stripping’’. The correct amount of chemical products needed to neutralise the polluted air has to be calculated.

  • Incineration Industry Emissions Monitoring & Analysis

    Monitoring of emissions from incinerators is a demanding application for Continuous Emission Monitoring Systems. The emissions produced are highly corrosive, some of the gases are soluble and, because the waste being burnt is constantly changing, the resulting stack gas temperature varies widely.

    Continuous emissions monitoring for CO2 capture

    The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3 and CO2. Measuring NH3 is a challenge due to the corrosive environment and high concentrations of NH3. Several places in the process needs to be monitored and to transport the sample is difficult. A large dynamic range is needed as the NH3 concentration can vary between 15% volume and a few mg/m3.

  • Water quality monitoring systems for cooling water treatment industry

    A number of treatment products are often added to prevent corrosion, scaling and fouling. Coating of sensors and other effects of these products must be taken into account when selecting analyzers. Discharge monitoring needs special attention because zero measurements must be reliable over time with little maintenance.

  • Ozone/UV systems for swimming pool water treatment

    Studies have proven that chlorine use has negative consequences due to the formation of byproducts, i.e. chlorinated organic compounds and chloramines. Irritation of eyes and mucous membranes, drying out the skin as well as “chlorine smell” are well known troubles. However, these byproducts also accelerate the corrosion in pool halls and significant risk is given by their toxicity (chloramines, combined chlorine) and/or carcinogenicity. Higher rate of asthma prevalence is one of the consequences. These are the reasons why the combined chlorine content - as a marker of chlorination byproducts presence - is to be monitored and why its limit values are specified by authorities. To meet the limits can be tedious and expensive because more water has to be changed and heated up. Chlorine disinfection is not sufficient to prevent infections caused by some waterborne pathogens as dangerous protozoan parasites Cryptosporidium parvum and Giardia lamblia.
