Reverse-osmosis (RO) developer Desalitech Inc has won a competitive bid to supply a water purification system using its Closed Circuit Desalination (CCD) system to the Kittansett Club golf course in Marion, Massachusetts, USA.
Wells that have historically supplied essential irrigation water are being impacted by accelerating seawater intrusion.
“At the end of the day when we looked at cost of ownership, operational cost, efficiency and the unit’s ability to manage varying salinity levels without upgrading equipment, Desalitech’s system was at the top of our list,” said John Kelly, golf course superintendent.
Desalitech‘s CCD products save water and lower treatment costs by 20-60% compared with other advanced systems, says the company. The process maximizes permeate recovery, thereby reducing brine waste and conserving water resources, while lowering energy consumption and increasing the flexibility and reliability of operations.
The Kittansett Club’s CCD unit will treat 100 GPM (6.3 L/s) of well water varying from 1,000 to 10,000 ppm dissolved salts. It is designed for maximum water utilization, capable of producing over 9 gal (34 L) of purified water from every 10 gal (38 L) it is fed, thereby minimizing well withdrawals and reject flow.
“Our proprietary CCD process has the ability to adjust to varying feedwater conditions, while operating at over 90% recovery with a single-stage RO,” said Richard Stover, Desalitech’s executive vice president. “We were the only bidder that could guarantee our system would perform as required if the feedwater salinity doubled.”
