| titleOfInvention | Process of dewatering sewage sludge |
| abstract | INVENTION OF: NORWOOD K. TALBERT FOR: PROCESS OF DEWATERING SEWAGE SLUDGE, ABSTRACT OF THE DISCLOSURE . Sludge from a municipal or industrial sewage treatment facility is mixed with a mineral acid or anhydride thereof to release the entrapped water in the sludge. The resulting mixture of said solids and diluted acid or anhydride is then mixed with a basic material, such as ammonia, the heat generated by reaction of the base and acid evaporates the water to form either a completely dry mixture of sludge solids and a salt, or a mixture having a predetermined moisture content which may be air dried. In some applications it is preferable to recycle a portion of the end product by adding it to the reaction vessel. |
