COAGULANTES DE PALMAS FORRAGEIRAS E OS EFEITOS NA TURBIDEZ E POTENCIAL HIDROGENIÔNICO EM TRATAMENTO DE ÁGUAS

Abstract

The present work aimed to analyze the use of forage palm coagulants and the effects on turbidity and hydrogenation potential in water treatment. Coagulation is a traditional technology that composes the initial stage of water treatment and aims at the removal and / or reduction of suspended and dissolved solids. In order to offer sustainable alternatives to the water treatment process, the objective of this work was to investigate the potential of three species of forage palms: Baiana Nopalea sp; the Little Nopalea cochenilifera sp and the Mexican Elephant Ear Opuntia stricta in the production of natural coagulants acting on turbidity and hydrogenation potential (pH) in the water treatment process. The results showed that pure green pastures of forage palms at different times of observation and weights actually reduce water turbidity from 65.95% to 69.91% and promote pH increases of 17, 33% the 30, 59%. The Mexican Elephant Ear Variety presented greater turbidity reduction power the longer the observation time and the greater the green mass weight and the lower acidifying power of the water.
