Propuesta de mejoramiento en el proceso de coagulación de las aguas residuales domesticas en la PTAR del municipio de Puerto Gaitán Meta

In this degree work, a proposal is developed to reduce costs in the coagulation-flocculation process, through research and bibliographic review of different studies consulted mainly in ScienceDirect, Scielo, Emerald Publishing and Elsevier where the improvement of these processes. Initially, an exhaustive investigation was carried out in which different aspects were taken into account, such as the type of waste water, specific pollutants, COD concentration, BOD5 and TSS, with these parameters coagulants that were effective in the treatment of ARD were chosen, evaluating the pollutant removal capacity of each of these coagulants, as well as the dose or dosage range where the best results are presented at the process and economic level. After the bibliographic consultation, the coagulants aluminum sulfate, ferric chloride and aluminum polychloride were chosen, since they presented the best trends in the removal of COD and TSS pollutants, among these, the poly aluminum chloride (PAC) was finally chosen as the best candidate for its high removal rate, as well as its excellent sedimentation of organic matter and in suspension at low dosages, showing that in a dosage range of 30 to 35 mg / L removals of 78% and 94% are achieved for the COD and SST respectively. Finally, the economic profitability of the proposal was evaluated through a financial analysis.
