Generating new sustainable alternatives in the design of trickling filters for rural
populations is necessary to improve the quality of discharges and optimize the design of
secondary treatment units. The study determined the impact of hydraulic and organic charge on
the removal of BOD in the environment charcoal biofilter. Biofilters prototypes were
implemented at scale with charcoal filter medium on different surfaces that vary from 0.12 to
0.25 m2
, carried out at an elevation of 2100 meters above sea level, the final concentration
most effective in removing BOD obtained hydraulic load of 2.34 to 4.76 m3m-2d
and the
organic load between 0.27 to 0.56 kg DBO m-3
. The results of the Biofilter experiments
determined that the hydraulic load generated a better distribution and mixing of the residual
water throughout the trickling bed, achieving a good reaction and effective combination
between the water that entered and the amount of air required to complete the aerobic process.
and to achieve the removal of BOD, the organic load obtained in the measurements
concentrates enough biomass that helps in the formation of the biofilm, for which it is
concluded that this criterion has a determining effect on the reduction of organic matter in
domestic wastewater, it is confirmed that the charcoal biofilter is efficient and can be used in
small systems of wastewater treatment plants.
