Organic filters, removal efficiency, chemical oxygen demand, biochemical oxygen demand, pre-treatment of wastewaterAbstract
The growth of cities is related to the increase in urban wastewater, in the study organic coconut fiber filters were designed for the pre-treatment of wastewater from laundries, physical activation of carbon was carried out, and combinations of physical and chemical activation, a removal efficiency was obtained in different efficiency percentages, filter 13 (Physical Activation) and filter 6 (Chemical Activation (ZnCl2) - 20% - 5 Hours), with a removal of 63.79% and 63.22% respectively for oils and greases, filter 1 (Chemical Activation (H3PO4) - 20% - 3 Hours) and filter 9 (Chemical Activation (KOH) - 20% - 5 Hours), with a removal of 33.21% and 32.69% respectively of biochemical oxygen demand, filter 10 (Chemical Activation (KOH) - 20% - 3 Hours) and filter 9 (Chemical Activation (KOH) - 20% - 5 Hours ), with a removal of 56.56% and 52.66% respectively of chemical oxygen demand, filter 1 (Chemical Activation (H3PO4) - 20% - 3 Hours) and filter 13 (Physical Activation), with a removal of 86.82% and 86.47% respectively of total suspended solids, filter 8 (Chemical Activation (ZnCl2) - 40% - 5 Hours) - 20% - 3 Hours) and filter 4 (Chemical Activation (H3PO4) - 40% - 5 Hours), with a removal of 89.71% and 76.46% respectively of ammonia.
