| titleOfInvention | BIOTECHNOLOGICAL PROCESS FOR THE TREATMENT OF HYDROXIDE MUDS WITH CONTENTS FROM PROCESSES OF WATER POTABILIZATION, USING FECL3 AS A COAGULANT, THROUGH THE ACTION OF SULFATE REDUCING BACTERIA. |
| abstract | The invention discloses a biotechnological process for the treatment of hydroxides sludges with As content from water purification processes, which use FeCl3, as a coagulant, through the action of sulfate reducing bacteria, which comprises the following steps: a.- prepare the culture of sulfate reducing microorganisms (SRB) for the process, said culture comes from the same mud that must be treated; b.- put in contact in an anaerobic bioreactor and for an approximate period of 5 days, the sludge to be treated, the inoculum obtained from stage (a) and nutrients such as ethanol, sulfate and yeast at a controlled temperature and with sufficient agitation that allow the homogenization of the sludge so that there are no areas left untreated; c.- sediment the treated sludge; for a period of approximately 3 days, the clarified is recovered and the sediment is then subjected to the drainage process by filtration or centrifugation; d.- filter the solid residue from the settler; e.- characterize the final waste The process developed seeks to modify the physicochemical characteristics of the sludge produced in such a way as to facilitate the use of mechanical dehydration methods that allow the volume of sludge produced to be reduced, thus facilitating its final disposal. |
