High Rate Aeration with OXY-DEP™ VSA

Air Products offers a unique wastewater aerator, which operates via the simple combination of an air blower and a gas separation bed. The OXY-DEP™ VSA technology works by replacing the inert nitrogen with high purity oxygen in your wastewater treatment process. This system uses a low-energy mixer to dissolve the oxygen and mix the tank contents.

In this way, OXY-DEP™ VSA technology can be used either to effectively upgrade an existing aeration basin, or as the principal supply route for dissolved oxygen to a high rate biological process. OXY-DEP™ VSA provides all the process advantages of oxygen, with power costs in line with conventional aeration (approximately 1kgO₂ dissolved per kWh energy used).

OXY-DEP™ systems are available in standard modules, ranging from 150lpm (approximately 250kgO₂/day) to 2500lpm (approximately 4500kgO₂/day).
