The Hadera Desalination Plant located in Hadera, Israel, is the world’s largest operating seawater reverse osmosis desalination plant. During the three and a half years it has been in operation, the plant has produced potable water for the State of Israel totaling 106 million cubic meters per year the first year, 127 million cubic meters per year the second year and 146 million cubic meters per year the third year.
The Hadera plant has an innovative operating regime where the pressure center design allows the water production rate to switch from 20,000 m3/hr during the night power tariff to 7,500 m3/hr during the day power tariffs. This change in operation regime minimizes energy costs.
IDE’s proprietary pressure center design consists of a pump center, a membrane center and an energy recovery center. It has the flexibility required to change water production and power demand in a smooth and effective way, without harming the desalination equipment. This centralized pump and energy recovery system, together with small membrane banks, is an effective solution for large desalination plants.
The pressure center enables the plant operator to optimize and select the operating regime on a day-to-day basis. Operating regime selection is based on a matrix parameter analysis of actual equipment availability, monthly production required, power cost, etc.
The combination of the proprietary pressure center design and operation regime enables Hadera to achieve one of the lowest-ever costs for high-quality desalinated water.
The paper will describe the challenging operation of variable production capacities and analyze the advantages of the Pressure Center Design and its contribution to the achievement of efficient and economical operation of the plant.
