Refineries and Petrochemicals


Wastewater treatment in downstream applications of oil and gas as refineries and petrochemical plants is a complex issue. With changing crude qualities and stringent regulations to meet demanding environmental management challenges, handling of byproducts which can be both volatile and toxic is a mammoth task for refiners. Petrochemical wastewater often requires a combination of treatment methods to remove oil and other contaminants before discharge. AQUARION provides a wide range of process equipment and services for wastewater treatment as well as recycling of water back to the process, thereby reducing the overall water consumption, including zero liquid discharge system.
