Hydraulic TurboChargers purchased for high capacity SWRO project Posted 07/25/06
Robert A. Oklejas, President of Pump Engineering, Inc (PEI) announced an order from Ion Exchange of Mumbai, India for 5 AT 3600 Hydraulic Turbochargers for the CPCL project in Chennai, India. This 30,000m3/d capacity system will be the largest sea water Reverse Osmosis plant in India and accordingly is a “high profile” project of significant importance to the Indian desalination industry.
Fitchner Consultants originally developed the plant specifications with flow work exchangers (FWE) as the ERD, however after evaluating PEI’s AT Turbocharger the specifications were changed to allow consideration of the Turbo. A detailed analysis by Ion Exchange showed the Turbo to be not only more efficient than the FWE, but with much lower capital. operating, and maintenance cost. Mr. Oklejas said that Ion Exchange selection of the Turbo over the FWE after a side by side comparison was not surprising. The cost savings were not only in the ERD, but the Turbo option required only one single stage pump in the high pressure circuit, a great savings over the multistage pump and high pressure booster pump associated with Flow Work Exchangers. The AT 3600 Turbos will be delivered in October.
On the brackish water side of RO, Mr. Oklejas announced an order from Aerex, a Florida based OEM for six (6) LPT 1000 Turbochargers for the James E. Anderson WTP in Port St. Lucie, FL. This municipal BWRO plant is a 12 million gallon per day system that employs the turbo as an interstage booster pump in a two stage membrane design. In brackish water RO plants the turbo lowers power requirements by 20 -30% and replaces an often very expensive brine control valve. Interstage boosting also balances flux rates between stages, thus lower the fouling potential of the 1st stage.
Another BWRO plant, Ulu Pandan will be receiving the first of thirteen LPT 2000 during the 1st week of July. This very low pressure system (1st stage feed pressure of 6 – 8bar) is again using the turbo as a zero energy interstage booster pumps. The 38 mgd facility, located in the island nation of Singapore is scheduled for start up in 2007.
