Dewatering solid-liquid matrices such as sludges
The solid-liquid matrix such as waste water sludge which has a structure is dewatered by simultaneous application of heat and pressure. The application takes place for 0.01 to about 20 seconds at a pressure of 45-6000 pounds per square inch(psi) at a temperature of 21-1000 deg C. La présente inventi...

| Zusammenfassung: | The solid-liquid matrix such as waste water sludge which has a structure is dewatered by simultaneous application of heat and pressure. The application takes place for 0.01 to about 20 seconds at a pressure of 45-6000 pounds per square inch(psi) at a temperature of 21-1000 deg C.
La présente invention propose de nouveaux processus pour l'égouttage mécanique d'une large variété de matrices solides-liquides, incluant des boues primaire et secondaire, qui impliquent l'application simultanée de pression et de chaleur aux matrices solides-liquides. |
