Evaluar el uso del polímero Floquat 2565 para tratamiento de aguas naturales en la planta Francisco Wiesner

Abstract

In order to replace the aluminium sulphate with polymer flocculant FLOQUAT 2535, a total of thirteen simulations were done, prioritizing this polymer to evaluate its flocculant action in waters from Chingaza National Park, obtaining a favorable change. This polymer was first characterized using several physico-chemical techniques, which made it possible to identify its distinctive characteristics and the particular characteristics that make it of higher yield than aluminium sulphate. Likewise, it was identified that the most adequate doses for handling the polymer in the Francisco Wiesner plant was 0.7ppm, corresponding to a daily water volume of around 10m3/s consuming 1,300 kg per day. The polymer is also used in maximum conditions where the pH is 7 when entering to the plant. By comparing the results obtained, treating the water with the polymer and sulphate separately, making physicochemical and microbiological analyses, which indicate how efficiently the product is, it is concluded that after the two hours that the plant requires to get stabilized, the polymer has a higher capacity of clotting, holds a major microbiological sample, is used in smaller quantities, does not affect the pH, removes the color of the water, and the filters have a longer lifespan because the floc is more consistent and the log removal has an average of 97%. Considering that the behavior of the polymer benefits the water treatment in the F. W’s plant, the required conditions and doses for the daily water volume are then evaluated. Because of sulphate replace with 10ppm polymer, the polymer is spent in smaller quantities than the sulphate, resulting in long-term chemicals savings.
