Abstract
ABSTRACT The rising cost of energy has put extreme pressures on the design and operation of municipal seawater reverse osmosis (SWRO) facilities especially in localities where electricity rates are high. To meet this challenge, creative approaches to SWRO system design and energy recovery devices (ERD) selection and utilization are required. Any successful approach will have to take into consideration not only the energy transfer efficiency of the particular ERD, but its level of complexity, ease of start-up, and capital costs in order to build a system with the lowest possible specific energy consumption (SEC). This paper will describe how a 4,500 m3/day municipal SWRO facility with energy costs exceeding 0.28 kH-h and an ERD supplier recently met this challenge and produced a system with a SEC of < 2.46 kW-h/m3. The first section of this paper will review three ERD technologies available on the market today: the Pelton impulse turbine; isobaric chambers; and hydraulic pressure boosters. Attention will b...
