METHOD OF DEWATERING DIFFICULT SLUDGES |
摘要 |
The present invention provides a new method for dewatering difficult sludges, such as autothermal thermophilic aerobic digestion sludges. The method incorporates a three-component treatment system. Initially, the difficult sludge is dosed with an inorganic coagulant and then the resulting sludge - inorganic mixture is dosed with a microparticle component. Lastly, the resulting mixture is dosed with a high molecular weight flocculant.
