#Oil in coolant series
A Turner Designs TD-4100 series monitor was selected to reduce maintenance hassles and insure compliance with the NPDES discharge permit.”
#Oil in coolant update
“The power plant decided to update the monitoring system with the latest monitoring technology. The TD-4100 series monitor, in conjunction with grab sampling, verifies NPDES discharge compliance for oil and grease in power plant cooling water. The power plant could not risk an undetected discharge of oil in cooling water with the DOW technology. Eventually, the articulated wiper failed and scratched the optical flow cell windows. This design proved to be very high maintenance and difficult to calibrate. The DOW utilized UV absorbance for oil detection and an articulated mechanical wiper design to maintain flow cell cleanliness. The municipal power plant had utilized a Dissolved Oil in Water (D.O.W.) monitor.
#Oil in coolant free
The permit also maintained the requirement that a continuous monitor verify that the discharged water was free of oil. As part of a NPDES permit renewal in the early 1990s, the power plant added a cement lined pond containing a slant rib separator to effect the mechanical separation of any oil present in the cooling water that is caused by a leak from a power plant engine. A primary component to keeping the economics favorable is the plant’s ability to continuously discharge uncontaminated cooling water into the canal system. The success of this municipal power plant relies on its ability to provide economical and uninterrupted power to its clientele. The plant is permitted to discharge several million gallons of cooling water on a continuous basis per day into a canal system. The open loop cooling water comes from ground water wells and is circulated through the stationary power plant engines. The cooling system for the power plant is a combination of closed and open loop cooling. The engines operate on a blend of diesel fuel and natural gas.
The engines produce power ranging from two to 7.5 megawatts per engine. The power plant engines are fired-up on short notice to meet the needs of the dispatcher. 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. The plant is part of a larger statewide power grid system.
