Advanced anaerobic digestion with external separation (High FOG, TSS Wastewater)

FLOTAMET: Anaerobic digestion system for high FOG and TSS waste streams

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

The FLOTAMET system’s superior FOD and TSS removal efficiencies increased biogas production, and improved wastewater effluent quality has been confirmed in several industries and different types of hard-to-treat wastewater.

A winning combination of GWE technologies achieves outstanding treatment effects, converting organic contamination into methane-rich biogas.  


  • Unmatched fat, oil, grease and solids removal from the wastewater with simultaneous biogas generation
  • 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 SUPERFLOTTM – 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.
