    Odor control for metal casting

    Use Ecosorb products to remove foundry smells naturally. Ecosorb odor control products by OMI Industries are extremely effective at breaking down and eliminating the many odorous gases produced by the metalcasting process. They chemically convert foul and potentially harmful gases into non-odorous byproducts. Within the metalcasting industry, Ecosorb products are effective on amines, sulfur dioxide, phenols, formaldehyde, ammonia, partially burnt hydrocarbons solvent odors and more.

    Chemical Water Treatment for cooling and processing water

    An optimal heat transfer is the most important point in every water cooled process. Scale, corrosion and biofouling negatively affect the heat transfer. Therefore Kurita develops for cooling and process water systems customized solutions, based on the combined treatments of scale & fouling prevention, corrosion inhibition, and biocides.

    algae control in drinking water plants

    By controlling algae, cyanobacteria and fouling LG Sonic can efficiently reduce taste and odor problems in a treatment plant. The performance of a drinking water treatment plant is consistent with the amount ol contamination in the water. Growth of algae and other fouling in and before a treatment plant can cause various problems within the process. In general, these issues are related with taste or odor of the water. Growth of algae, cyanobacteria and bacteria within the basins of the plant itself, increase the demand of chemicals or filtration and in turn creating problems with THM (trihalomethane) formation. Other common issues are growth of toxin and geosmin producing cyanobacteria (blue-green algae) within the intake reservoir or dam. These molecules give the water an unpleasant `earthy ` taste.

    Chemical Water Treatment for cleaning

    Deposits in water systems, especially in heat exchangers, result in a significant heat transfer reduction, in low efficiency and a loss of cooling capacity. Some systems, after long operational periods without any water conditioning or with inadequate treatment, need cleaning. Therefore Kurita Water Solutions proposes acidic, alkaline and neutral cleaners to remove deposits, scale, fouling, dirt, grime or impurities.

    Filtration solutions for pre-treatment for desalination industry

    In desalination plants it is of great importance for the operation of the entire plant that the pre-treatment of the water is good before the salt is to be removed. For reverse osmosis (RO) desalination plants a good pre-treatment is essential for avoiding membrane fouling, resulting in reduced water production and increased operational costs.

    Monitoring of leaks in heat exchangers

    The Situation

    A California refinery produces xylene for use as commercial product and a precursor for petrochemical manufacturing. A primary component to the production of xylene is the isolation and purification of the chemical from a complex mixture of petroleum hydrocarbons. Steam based heat exchangers are used to process the xylene. Inherent to the design and rough duty heat exchangers face during their operation, leaks can and do develop. When a heat exchanger leaks, xylene contaminates the steam and produces a number of problems ranging from loss of final product, contamination and fouling of steam transfer piping, and ultimately bio-fouling of cooling towers. Consistent and reliable monitoring for xylene or other petroleum hydrocarbons in cooling water or steam condensate can alleviate product loss and process equipment down time.

    Chemical Water Treatment for membrane treatments

    Membrane units, in our days are widely used in the water pre-treatment preparation and are becoming one of the most important technologies in the production of high pure water. Nevertheless they often face problems with scaling and fouling and are therefore limited by frequent maintenance, downtime and high costs. Our treatment programs are specifically designed for membrane units like reverse osmosis, ultra- and nanofiltration and enable to remove or preventive control scaling and fouling. Our main target is to run these plants under environmentally friendly and beneficial economic conditions. Special attention is given to an efficient utilization of energy as well as saving precious water. Kurita develops an efficient and effective treatment concept achieving an optimal economic operation and a maximum operational reliability of a plant.

    Precision moisture analysis instruments for measuring moisture and ash in biomass

    If you produce or consume biomass fuels, you know that quality is critical to your success, and you know that moisture and ash content control are critical to biomass fuel quality. Too much moisture and you get poor efficience and high emissions. Too much ash and you get fouling and slagging. And if either of those is uncontrolled, purchase contracts can fall through. Computrac can help.

  • RailScan

    Ground Penetrating Radar to Evaluate Rail Ballast, Sub-ballast and Sub-grade. Railroad maintenance and service providers have traditionally relied on visual inspection and excavation to assess ballast condition and measure sub-ballast and sub-grade. Ground penetrating radar is used to indicate ballast fouling and accurately measure the structural layers to a higher precision and in far less time than with traditional methods.

  • Hydrogen Sulfide (H2S) monitoring

    Hydrogen sulfide is the chemical compound with the formula H2S. H2S is colorless, toxic and flammable and is responsible for the foul odour of rotten eggs and flatulence. Hydrogen sulfide often results from sulfur reducing bacteria in nonorganic matter (in the absence of oxygen), such as in swamps and sewers (anaerobic digestion). H2S also occurs in volcanic gases, natural gas and some well waters.

  • 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.

  • Natural gas gathering system for inlet gas separation

    Natural gas gathering systems deliver large volumes of gas via pipleline to the central inlet of the gas processing facility. Removal of solid contaminants and free liquids present in the inlet gas is critical to the downstream process. Iron oxides, iron sulfides, dirt and other deformable particles can flow into the processing system. Effective removal of these contaminants is needed to prevent fouling. Pentair Porous Media technologies will help with a clean, natural gas feed, reducing upsets and associated downtime and increase productivity, lowering capital costs with fewer change-outs.
