A liquid concentrator system includes a concentrator or section having a gas inlet, a gas outlet and a mixing corridor disposed between the gas inlet and gas outlet. A liquid inlet is disposed in the mixing corridor between the gas inlet and a narrowed portion. A demister is disposed downstream of the concentrator section. The demister includes a liquid collector to removed liquid from gas flowing through the demister, and a reservoir that collects the removed liquid. A recirculating circuit is disposed between the reservoir and the mixing corridor to transport liquid within the reservoir to the mixing corridor and secondary re-circulating circuit includes a settling tank to separated saturated liquid and suspended solids. A custom brine mixing device is operatively coupled to the settling tank.
