Temporary slurry sprayed permeable cover design for erosion protection and passive biofiltration of methane, volatile organic compounds (VOCs) and odors from area sources.

摘要

This invention is a permeable cover layer for the control of methane, volatile organic compounds (VOCs) and/or odor causing compounds. It is designed to control emissions from area sources such as: composting operations (household and animal wastes), anaerobic digesters, organic sludge drying operations, waste storage operations, contaminated soils storage or treatment operations. The control is achieved through a combination of activated carbon adsorption and passive (i.e. no active ventilation) biofiltration.
