Inland Empire Paper Co. Applying Algae-based Wastewater Treatment
Millwood-based Inland Empire Paper Co. is studying a new biological technology to reduce the amount of phosphorus in the wastewater it discharges into the Spokane River during its paper-making process.
For about two years, the 100-year-old paper mill has been working with Corvallis, Mont.-based AlgEvolve Inc., to study a wastewater treatment technology that company has developed using algae to remove phosphorus in the wastewater.
