Anaerobic water purification systems for bioenergy - Energy - Bioenergy

Paques has a very interesting position in the bio-energy sector, being both: Supplier to the bio-energy industry and Producer of bio-energy.

Paques offers solutions to the sector (e.g. bioethanol and biodiesel producers) for treatment of their water and gas effluents in order to comply with discharge regulations and to produce biogas from their wastewater.

Over 900 Paques BIOPAQ® installations produce biogas that meet the natural gas requirements of 2.4 million Dutch households.

Paques is dedicated to getting the most from the raw materials to produce bio-energy.

Whenever wastewater or digester feed contains sulphur compounds, the generated biogas will contain hydrogen sulphide. The THIOPAQ® desulphurization process removes this compound cost effectively at very high uptime (> 98%).

Activated sludge systems remove the remaining COD after anaerobic treatment. Other Paques technologies recover phosphate and remove ammonium.
