Method for processing a watery substance with zeolites

A method for processing a watery substance containing solids, comprising:

• a) mixing a watery substance containing solids in a mixer-drier with zeolites of type A and forming a visually dry mixture of zeolites of type A and dried matter, said zeolites of type A absorbing moisture from the watery substance and releasing heat which evaporates moisture from the watery substance,
• b) regenerating the zeolites of type A by heating to remove the moisture adsorbed therein;
• c) separating the zeolites from the dried matter;
• and
• d) recycling the zeolites of type A to the mixer-drier for reuse.

A method for processing a watery substance containing sludge or manure, comprising:

• a) mixing a watery substance containing sludge or manure in a mixer-drier with zeolites of type A and forming a visually dry mixture of zeolites of type A and dried matter, said zeolites of type A adsorbing moisture from the watery substance and releasing heat which evaporates moisture from the watery substance,
• b) separating the zeolites from the dried matter;
• c) regenerating the separated zeolites of type A by heating to remove the moisture adsorbed therein;
• and
• d) recycling the zeolites of type A to the mixer-drier for reuse.
