Ozone generators produce concentrations from 10% to 15% of ozone in the feed gas. In this way, 85% to 90% of the feed gas consumed is not used and represents a huge cost that makes ozone expensive.
Air Products has developed adapted technologies to reuse this off-gas into a wastewater biological plant. Without compression stage, with a simple self-aspirant device, the ozone off-gas is recovered and used to aerate a biological plant. In this way, the oxygen is valued in the aeration process where energy could be saved.
