Membrane Technology
Prejudices about membrane technology
• Pre-treatment is needed• gas contamination
cannot harm themembrane
• If contaminationhappens membrane canbe brought back to original performance
Our 3 largest installations:• 6,250 Nm³/h• 5,340 Nm³/h• 4,000 Nm³/h • Plus 30 projects > 1,000
Nm³/h raw biogas
• Most efficienttechnology
• reliable and flexible• best optimum between
capex and opex• development ongoing
