【正文】 ss when a part of the biological solids were disintegrated with alkali at pH 11 and temperature 75℃ .Thermo chemical sludge digestion favors the recovery of phosphorous in the supernatant using calcium salts. The system can run for a long period of time with any further detoriation in TP removal efficiency. Further studies focusing on fate of disintegrated sludge are in progress. References 1.
