Estandarización de la planta de tratamiento de lodos generados por la planta potabilizadora de Tixán

Abstract

The sludge dewatering process includes operations such as decantation, thickening, preparation of the polyelectrolyte solution, flocculation and filtration with band filter, each one of them are essential in Tixán water treatment plant, therefore, the standardization of each one of the stages of the process is desired, previously performing an analysis of the data obtained from the process that is currently executed in the plant to make experimental tests, varying different parameters with the goal of determining the suitable conditions for sludge managing in the plant and in compliance with the current legal regulations (TULSMA) for effluent discharges to a fresh water body. This project analyzes factors that interfere in the results of sludge flocculation and dewatering, trough experimental tests such as: jug tests, sludge flow control, filtration tests to enhance the filtering operation (band filters) and to increase the sludge dewatering percentage in Tixán plant, this way the decrease of the microorganisms growth process will be achieved, for a better handling and possible reutilization of the sludge. Also verifying the suitable plant design to analyze possible mistakes on it if needed, to recommend changes or adjustments in the procedural manual that will be elaborated. Finally, a procedures manual will be delivered, and it will be documented inside the plant, for future process control.
