Analysis of the pretreatment of wastewater from laundries through organic coconut filters

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.
