Abstract
This study aims to get the design process and the economics of small-scale desalination of brackish water in Indonesia which has interest in the range of 12-14%, electricity cost of $0.09-0.13/kWh, and groundwater tax regulation. The use of BWRO desalination system in Indonesia has been generally done at small scale. This study based on Bali island with electricity cost at $0.1/kWh and water tax at $0.37/m 3 . Techo economy evaluation was analysed for plant capacity of 150-1,00 m 3 /day, recovery of 40% with brackish water water salinity of 5,000 ppm. Price of desalted water during first year a case study is $1.31/m 3 . It can be concluded that e conomic evaluation based on NPV and IRR shows that it is worth ed.
