The Komax sludge heat exchanger can be utilized for mixing and heating municipal sludge, FOG, and manure for aerobic/anaerobic digestion purposes. The sludge to sludge heat exchanger can also be used for reclaiming heat from hot outgoing digested sludge to heat the cold incoming sludge. The Komax sludge heat exchanger enhances biogas production and also helps in production of Class A biosolids.
The sludge heat exchanger or Klean-Wall Heat Exchanger used to heat sludge in a recirculation loop with a digester, utilized for co-digestion process. The sludge heat exchanger is more thermally efficient than a straight shell and tube heat exchanger due to the patented non-clogging mixing elements know as Hi-Pass mixing elements, in the process pipe tubeside and in the shellside. This technology keeps the pipe walls clean and results in much more consistent performance over time with no build up, scaling or plugging of the waste treatment facilities effluent line. Due to the heat transfer improvement Komax shell and tube heat exchangers can be 50% smaller than a standard heat exchanger for the same heating application.
