BIOPAQ® UASBplus

BIOPAQ®UASBplus is Paques best solution for any industry with wastewater that contains high concentrations of soluble organic pollutants. This next-gen Upflow Anaerobic Sludge Blanket can treat high COD levels in new installations & in existing wastewater treatment systems.

As the focus on water recycling increases, Paques anticipates demands for treating wastewater with higher COD levels, a trend already visible in the food and bio-ethanol industries. The BIOPAQ®UASBplus technology has been designed for this specific development.

Anaerobic effluent treatment at low TCO

BIOPAQ®UASBplus is a flexible solution for anaerobic effluent treatment at low total cost of ownership. It can be applied to a wide range of wastewater types and is specifically suitable to treat concentrated wastewater with COD measuring 15,000 to 60,000 mg/l.

In the BIOPAQ®UASBplus bioreactor, organic compounds (COD) are converted to biogas by bacteria in the absence of air. In this way, effluent discharge costs are reduced and at the same time green energy is produced.

This system excels thanks to its highly effective separator design. This ensures very efficient biogas collection and optimal biomass retention. The modular separator can be mounted in any new or existing tank (welded steel, bolted steel, concrete or GRP).

BIOPAQ®UASBplus is already applied successfully in several industrial scale plants. A pilot plant is available for on-site testing.

Advantages of BIOPAQ®UASBplus

  • Production of consistent effluent qualities
  • Production of biogas
  • Modular three-phase separator that can be mounted in any new or existing tank
  • Closed system: no odour emissions
