| 摘要 |
The invention relates to a tube bank heat exchanger for use in reducing the temperature of air delivered under pressure to an air diffuser system within a wastewater treatment facility. The tube bank heat exchanger, submerged within the wastewater, is of a configuration which extends the air flow path from the air source to the diffuser system. By such configuration the temperature of the air delivered to the diffuser system is reduced to a temperature of no more than about 140 degrees F.
