ABSTRACT:
A pathogen reduction system for a sludge treatment process that employees multiple reactors operating in a batch mode to reduce pathogen levels in the sludge while providing a continuous flow of pathogen reduced sludge to a digester. In addition, the present invention entails an efficient heat exchanger for heating and cooling the sludge being treated in the above process. In particular, the heat exchanger is of the counterflow type and includes a helical coil confined in an annular chamber for transmitting one media and wherein the helical coil is spaced so as to form another helical flow channel that is defined by the annular chamber and the helical coil itself. Consequentially, one media is directed through the helical coil while another media is directed through the flow channel that is defined in part by the helical coil.
