Air strippers are primarily used to remove which type of substances from water?

Air strippers are primarily designed to remove volatile organic compounds (VOCs) from water. This technology utilizes the process of mass transfer, where air is introduced into a water stream, allowing the VOCs to evaporate into the air. This is particularly effective for removing substances that have high vapor pressures and low solubility in water, which are characteristics typical of many volatile organic compounds.

By effectively increasing the surface area where the air and water contact each other, air strippers create optimal conditions for the VOCs to volatilize. The method is widely used in groundwater remediation and treatment systems, as it helps to significantly reduce the concentration of these harmful pollutants before the water can be safely discharged or reused.

Understanding the specific application of air strippers is crucial for addressing concerns related to water contamination, as they provide a reliable solution for removing specific contaminants like VOCs, enhancing water quality and safety.
