Evaluación de la eficiencia del carbón activado procedente del pseudotallo de plátano (Musa paradisiaca L.) para su uso en remoción de contaminantes en agua de pozo.

Abstract

The objective of this investigation project will be to evaluate the effectiveness of activated carbon (AC) from the banana pseudostem (PP), varying the size of the particles to determine its percentage of pollutant removal in water from the deep well (APP) of the Island Santa Cruz. It will be a descriptive investigation in which data will be evaluated through the Analysis of Variance. Three filters will be designed with 100 g of activated carbon each with pore sizes of 1.70, 1.18 and 0.60 mm. CA will be obtained by the chemical method using 85% phosphoric acid with the 1:1 impregnation ratio at 600 ° C for 2 hours. The collection of the APP will take place on Monday, Wednesday and Friday at 10:00 a.m. and 3:00 p.m. for 7 weeks. The qualitative variables smell, taste, color of filtered (AF), and unfiltered (ANF) water will be evaluated in non-numerical terms. Comparing the results with the NTE INEN 1108 standard, for the quantitative variables it is estimated to obtain the following values: pH 9.0 (CA), 7.3 (ANF); humidity 5.890 % (PP), 9.8-12.75 % (CA); ash 16.290 % (PP), 19.24 % (CA); 89 % hardness (CA), 154 mg / L (ANF), 30.18 - 40.24 mg / L (AF); methylene blue adsorption 778 m² / g (CA), iodine number 740 mg / g (CA); iron 0.7 mg / L (ANF), 0.01 mg / L (AF); lead 0.01 mg / L (ANF), lead 99.91 % (AF), fecal coliforms 0 CFU / 100 mL (ANF), 18.67 - 110 CFU / 100 mL (AF); turbidity 0.36 NTU (ANF), 0.319 - 0.72 NTU (AF). The benefit-cost analysis will demonstrate the research project feasibility.
