Advanced anaerobic digestion with external separation

Dairy factories, palm oil and coconut oil processing plants, slaughterhouses, and others face tremendous operating issues with their wastewater systems. Heavily polluted with fat, oil, grease and solids, post-production wastewaters can be very troublesome, and requires a solution to be treated.

Converting organic contamination into methane-rich biogas

GWE’s FLOTAMET Anaerobic Digestion System is designed for high Fats, Oils, Gases (FOG) and Total Suspended Solids (TSS) in waste streams. The FLOTAMET system’s superior FOD and TSS removal efficiencies in increasing biogas production and improving wastewater effluent quality have been confirmed in several industries and different types of hard-to-treat wastewater.

A winning combination of GWE technologies achieves outstanding treatment effects via removal of unmatched fat, oil, grease and solids, simultaneously converting organic contamination into methane-rich biogas.


  • No primary treatment needed due to use of GWE’s ANAMIXTM CSTR anaerobic digester decreases capital costs of the industrial wastewater treatment plant
  • External sludge separation by SUPERFLOT – BIOGAS Dissolved Biogas System maintains high biomass retention within the system
  • No need for expensive granular seed sludge
  • It treats the waste and wastewater streams untreatable by other anaerobic digesters – organic contamination up to 100,000 mg/l COD.
