System and method for reducing the pathogen concentration of sludge |
| abstract |
A waste treatment system comprises a first heat exchanger positioned before one or more reactors. The reactors discharge treated sludge to a second heat exchanger. The first and second heat exchangers share a heat transfer medium wherein the heat from the treated sludge is transferred to the incoming sludge. The treated sludge is cooled to reach an optimal temperature range before entry into a digester. The system also is adapted to allow a pipe cleaning device or “pig” to clean the heat exchangers by being forced through the heat exchangers by pressurized and pasteurized wastewater. |
