FAQ
Frequently Asked Questions about SWAPL
We use an Energy Recovery Turbine (ERT) in the SWRO system to significantly reduce power consumption.
We use HCl for pH adjustment, SMBS to neutralize chlorine, and antiscalants to prevent scaling in both SWRO and BWRO stages.
The two-stage system (SWRO followed by BWRO) allows for higher purity, better system efficiency, and optimized operational costs.
Plans include operating fully on green power, expanding capacity, complete automation, introducing electrochlorination, supplying brine to salt pans, and establishing a bromine recovery plant.
