The high capital and operating cost of the reverse osmosis systems, the monopoly of the water treatment companies in addition to the complication related to the design present obstacles in the residential water treatment field.
WATCHE by HJM group provides a simplified, friendly-user simulator for Reverse osmosis systems; WATCHE first generates costing curves based on iterative loops benchmarked on the software ROSA coupled with extensive computational calculations.
WATCHE can directly provide the price for all the systems that treat water effluents having the concentration of the total dissolved solids ranging between 500 and 8000 mg/L, and generating permeate flow rate ranging between 4 and 120 m3/day.
Furthermore, the high operating cost is reduced by replacing the conventional power supply by solar power, showing a reduction in operating cost for more than 50% over 10 years period.
