Waste water treatment plants and landfills produce biogas, a mixture of methane, carbon dioxide, and water vapor. Many WWT plants and landfills burn the gas onsite to produce hot water or electricity. Lowering the water content of biogas prior to combustion improves operational performance by eliminating corrosion in boilers and preventing damage to gas engines and micro-turbines.

Van Air Systems D Series dryers are well suited to biogas drying information. The capital cost of D Series dryers is a fraction of refrigerant type drying equipment. And with no power required, D Series dryers avoid special electrical requirements that apply to hazardous area operation. Also D Series dryer exhibit extremely low pressure drop, which is critical in biogas applications where gas pressure is often 5 PSIG or lower.
