摘要
TITLE OF INVENTION PROCESS FOR ENHANCING THE DEWATERABILITY OF WASTE SLUDGE FROM MICROBIOLOGICAL DIGESTION The present invention is concerned with a process for enhancing the dewaterability of a waste sludge having a substantial content of water-retaining cellular structure arising from microbiological action and having a solids content of seven to fifteen percent by weight. The pH of the sludge is adjusted to 4.0 or less, the sludge is subjected to heat treatment to significantly enhance its filerability, the pH is again adjusted to near neutral, the sludge is subjected to a second heat treatment step, and the sludge is filtered to a final solids content in excess of about fifty-five percent by weight. 3743/DCPAT
