  • WASTE WATER HEAT RECOVERY SYSTEM
    Publication number: 20170254595
    Abstract: A waste water heat recovery system may include a waste water conduit, a plurality of heat exchanger modules, an inlet manifold, and an outlet manifold. The plurality of heat exchanger modules may be disposed on an outer surface of the waste water conduit. Each of the plurality of heat exchanger modules may include a first conduction member, a second conduction member, and a multi-stage serpentine potable water conduit seated between the first and second conduction members. The inlet manifold may receive potable water from a water source and may be fluidly connected to an inlet of the potable water conduit of each of the plurality of heat exchanger modules. The outlet manifold may be fluidly connected to an outlet of the potable water conduit of each of the plurality of heat exchanger modules.
