| titleOfInvention | treatment and recovery process of mineral-contaminated primary sludge generated in the pulp and paper industry |
| abstract | The present invention is a mineral filler contaminated primary sludge treatment and recovery process generated in the pulp and paper industry and a chemical product thereof, particularly a treatment and recovery process. primary sludge, obtaining unbleached and pre-bleached clean cellulose for application in general papermaking. The present invention discloses a process of separating the mineral fillers and the organic contaminants contained in the fibers by means of a simultaneous physicochemical and mechanical process which provides for the purification of primary sludge into clean cellulose. The process of treatment and recovery of contaminated primary sludge comprises the following steps: 1.1.- supply of the pulp purification process; 1.2.- dilution and washing of contaminated primary sludge (physicochemical process); 1.3.- separation of inorganic contaminants, ie soluble mineral and organic fillers (physical-mechanical process); 1.4.- cellulose separation and pulp densification; 1.5.- fiber pre bleaching; 1.6.- dewatering and concentration of fibers for application and reuse; and 1.7.- wastewater treatment. |
