A carbon-containing compound with high vapour pressure at ambient temperature. VOCs at the water-air interface drive air-quality compliance and odor.
A VOC (volatile organic compound) is a carbon-containing compound with a high vapour pressure at ambient temperature. VOC release from open water surfaces — in oil and gas produced-water ponds, food and beverage processing, wastewater, and chemical operations — drives air-quality compliance under the EU Industrial Emissions Directive and adjacent national regulations. Floating covers reduce VOC release by 70–85% by reducing mass transfer at the water-air interface.
