    Monitoring of fuels in stormwater

    The Situation

    A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of compliance discharge by capturing all stormwater in storm drains, which is then sent to...

    Monitoring of hydroelectric dam sumps

    The Situation

    Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage:

    • The hydroelectric turbines are lubricated by lubrication oils.
    • The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils.
    • Vehicles including fork lifts, trucks, etc., can spill oils and fuels.

  • Monitoring petroleum hydrocarbons in wastewater - Water and Wastewater - Water Treatment

    Monitoring petroleum hydrocarbons in wastewater

    The Situation:

    A wastewater treatment company operated an oil/water separation facility on a multi-acre industrial site in Northern California. Its purpose was to recycle oil products for profit while at the same time providing a wastewater treatment service for industries based in Northern California.

  • Monitoring of phenol in water - Water and Wastewater - Water Monitoring and Testing

    Monitoring of phenol in water

    The Situation

    A plant located in the eastern United States manufactures phenolic resin for applications in plastics molding. This plant uses well water for cooling its reaction process and then discharges the water into a local creek.

  • Monitoring of raw water intake - Monitoring and Testing - Water Monitoring and Testing

    Monitoring of raw water intake

    The Situation:

    Hydrocarbons in municipal water supplies,  including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through undetected. Desalination systems using reverse osmosis (RO)...

    Monitoring once through cooling water

    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 use once through cooling water systems. The cooling water is taken from lakes, rivers, or the ocean and circulated...

  • Monitoring oil in power plant cooling water - Energy

    Monitoring oil in power plant cooling water

    The Situation:

    A municipal power plant in the southern United States operates more than 10 stationary power plant engines capable of producing 52 megawatts of electric power. The plant is part of a larger statewide power grid system. Within the grid, the municipality brokers the purchase or sale of power hourly, based on the needs of municipality and the market rate for power on the grid system.

    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,...

  • Monitoring of hydrocarbons in bilge water - Water and Wastewater

    Monitoring of hydrocarbons in bilge water

    The Situation

    Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited by national and international regulations.

  • Monitoring of heat exchanger leaks in paper plant - Pulp & Paper

    Monitoring of heat exchanger leaks in paper plant

    The Situation

    A paper plant in the Eastern United States uses 500 gallons per minute filtered pond water for cooling lubricating oil in its paper line. The resulting warmed water is diverted to an onsite pond. Because the water is used to cool lubricating oil, the plant could not reuse the water in its pulping process for fears of possible oil contamination of the paper pulp.
