Tratamento alternativo da água utilizando mandacaru (Cereus jamacaru) e palma (Opuntia cochenillifera)

Abstract

Considered an essential and indispensable element for the maintenance of life, not only for its important characteristics, but mainly for the fact that the metabolic process occurs without the action of water. Making your presence in appropriate conditions essential. Water is considered polluted when its physical, chemical and / or biological characteristics are known to be altered by anthropic actions, making its use unfeasible. The treatment of water has the effect of attenuating impurities, correcting some parameters to make it water. The use of natural coagulants has advantages when compared to chemical coagulants, as they are biodegradable and non-toxic, and still produce less sludge and with low levels of metals. Therefore, the present study aimed to perform an alternative water treatment using Mandacaru and Palma, verifying its efficiency through the presence of aerobic mesophilic microorganisms, total coliforms and Escherichia coli. Two collections were performed, with analyzes at TEMPO 0 (before sun exposure) and TEMPO 1 (after sun exposure). All the analyzed controllers, in both collections did not have satisfactory results for the control of coliforms. The treatment using Mandacaru is used more efficiently to control the Mesophilic and E.coli bacteria. However, it is necessary to conduct more research on the microbiological treatment of water using Mandacaru and Palma, associated with other disinfection methods.
