Abstract
A method for transferring heat includes flowing a wastewater through a tank and flowing a fluid through a heat exchanger having an outer surface. The method further includes aerating the wastewater to produce a convective flow, contacting the outer surface of the heat exchanger with the convective flow to exchange heat, and cleaning the outer surface of the heat exchanger with the convective flow. A system for transferring heat includes a tank, a heat exchanger with an outer surface disposed in the tank, and a fluid flowing through the heat exchanger. Wastewater located in the tank flows over the outer surface of the heat exchanger, and a diffusion pipe disposed in the tank provides air into the tank to produce a convective flow in the wastewater.
