Abstract:

This research work was conducted with the waste water from the spinning mills, Canton Guano, in order to provide a solution to the problem of pollution that origínate from these waters because they are not properly treated before being discharged into the riverbeds.
Different methods, procedures and analysis was used in the laboratory for the collection and identification of physico-chemical wastewater characterization parameters and filter material (corn cob or gopher). After that the design and construction of the filter (prototype) was performed for different practices in the laboratory, with the following specifications, a tank inlet and outlet (0.30m x 0.15m) filtration zone (0.80m x 0.60m) with different compartments or chambers (0.30m x 0.15m), and plates or separation baffles equally spaced holes.
In the characterization process corncob of different particle sizes were used in the filters (prototypes) made of plastic containers for treatability tests in which were observed a satisfactory result in reducing colors in wastewater was obtained using sample 2 of cob or corncob with 4,5mm in size and sample 3 with 2.36mm in size.
As a result of the investigation it was determined that the best application of cob or corncob as bed filter to reduce the color of wastewater, thus through various tests it was determined that the cob filter or corncob was 2.3 TP (Sample 2 sizes of corncob or cob 4.5 mm, sample 3 size: 2.36 mm and gravel) being the most optimal, leading to reduced light colors 55, 52%, dark colors 67.65%. Also obtained was activated carbón from the cob or corncob which was 50.72% efficient in a color reduction in wastewater, obtaining the optimum filter bed as the final results in the prototype was 2.3 TP and CAT ( cob sizes or corncob 2 shows the number of size 4.5 mm, sample number 3 of size 2.36 mm, gravel and activated carbón from cob or corncobs) decreasing by 78.63%, for which the best applicability of the cob or corn cob as filter bed should be as an individual process for each color, which is to eliminate the visual impact that is generated when discharging the effluent to the river bed Guano.
