Filter Efficiency with Red Rock as Post-Treatment of Stabilization Pond Effluent, Prototype Case Study San Marcos, Carazo, from April to September 2019 ()
ABSTRACT
An experimental unit was built which was located in the vicinity of the
domestic wastewater treatment plant of the Municipality of San Marcos in the
Department of Carazo.
Said unit consisted of two welded metal barrels with a total height of 1.8 m and a
diameter of 0.90 m, likewise, this unit comprised three functional zones; the first or input area
composed of a collection unit, a driving unit, a flow control unit, and two
distribution units; the second or packed zone, which is the axis of the system
because it is there where bacterial growth takes place and where the removal of
organic matter takes place; and an outlet composed of PVC pipe [1]. The
main objective of this work was to determine how efficient a rocky filter turns
out to be, using stabilization pond effluent as a post-treatment unit using red
concrete as a filter medium. The study consisted in carrying out laboratory
tests on water samples taken from the influent and effluent of a filter made up
of red rock, as a filter medium, in order to determine the percentage of
organic matter removal efficiency that it has used a hydraulic
retention time of 19 hours, 15 hours, and 12 hours [2]. Among
the aspects to be considered in the experimental study was the characterization
of the effluent from the treatment system of San Marco, Carazo, to determine
the quality of water that will be of interest to the study [3]. In
this stage, four composite samplings were carried out, two of 12 hours and two
of 24 hours, in which physical, chemical, and
microbiological parameters were analyzed. Likewise, to determine the efficiency
of the filter, the same parameters considered in the characterization of the
lagoon effluent were analyzed, obtaining removal efficiencies of up to 55.53%
in organic matter, and 64.60% in suspended solids for a hydraulic retention
time of 19 hours; In the same way, the efficiency of the filter was carried out
for retention times of 15 hours and 12 hours, in which organic matter removals
of 67.84% and 56.59% and 82.77% and 77.51% in total suspended solids were
found, respectively.
