Production and application of low cost filter with activated charcoal from native açaí kit waste

ABSTRACT

This research aimed to produce activated carbon (AC) from the seed of açaí of the native species Euterpe precatoria, as well as to perform physical analysis of the AC and verify its filtering capacity. For this, three different types of AC were carried out, two of which were carried out in the laboratory with the variation of temperature and exposure time and another type of AC carried out in the field (rural area). The AC produced, both in the laboratory and in the field, had a significant reduction in apparent mass and electron microscopy proved to be of good quality. The filter with açaí stone charcoal proved to be effective in partially removing coliforms and with a significant increase in pH, it raised alkalinity and conductivity levels, reduced hardness and improved turbidity, and proved to be a great tool that, added to the chlorination process, it can take treated water to isolated communities that do not have access to treated water, having characteristics of low cost and reuse of waste.
