Cherokee Wastewater Treatment Plant (USA)


IDE’s unique high-recovery RO solution, MAXH2O-PFRO product implemented at the Cherokee Metropolitan District’s wastewater treatment plant, helping the city to comply with the Colorado court order for the district to lower its TDS discharge to under 400 mg/L.

The MAXH2O-PFRO will reuse a secondary effluent and produce ~8000 m3/d permeate mixed with the District’s MBR filtrate to dilute the final effluent to meet the requirements.

“IDE truly stood out from competitors with its MAXH2O-PFRO technology and high-recovery RO solution. Not only did IDE bring a solution that would resolve our pain points and comply with regulation, the company has unmatched experience in handling challenging water chemistry and offers the ability to install faster at lower rates.”
