Core Competencies


Anaerobic Wastewater Treatment
Complex Wastewater Treatment Solutions

Paques is a market leader in the field of anaerobic treatment and designs and supplies plants for COD conversion into biogas. Paques has developed the BIOPAQ® product series to treat complex wastewater for industries such as food & beverage, pulp & paper, distilleries, and pharma.

Paques focuses mainly on reject water treatment from sludge digestion, post-treatment of anaerobic effluent, and effluent polishing at municipal and industrial wastewater treatment plants.

Metal Removal and Recovery
Recovering Valuable Resources
