Power plant motor coolant piping

The Haifa Wastewater Treatment Plant, operated by the Haifa Region Association of Towns – Sewerage, handles wastewater from the eight local authorities  that are members of the Association. The wastewater treatment plant also handles wastewater from area factories and kibbutzim. An average of approximately 100,000 m³ of wastewater is handled each day. Methane gas, which is produced in the anaerobic fermentation process, is used as a source of energy. The treatment plant has a power plant that produces electricity with special motors that are driven by methane gas. The power plant supplies about 50% of the electrical consumption of the treatment plant. The coolant used in the power plant motors is used to heat the sludge in the digesters. The temperature of the coolant in the motor is about 80°C. Since 1961, when the treatment plant was constructed, the coolant has been carried through steel piping. The coolant is treated water and is corrosive and causes damage to the steel piping. The Association has been forced to refurbish the steel piping damaged by corrosion many times.

 In 2013, the Association management decided to replace the steel piping with 280 mm diameter Pexgol piping after testing the resistance of the Pexgol piping when carrying water at temperatures of 80°C, as well as its resistance to corrosion. The Association purchased and installed 360 m of 280 mm Pexgol piping for carrying the heat from the power plant to the digesters in June 2013. The piping is operating well and satisfactorily without malfunction.
