Tratamento de água de um açude na cidade de Surubim-PE com sementes de Moringa Oleifera

Abstract

Brazil is the largest mainland water holder of the world. But in recent decades, this feature has been a source of concern because the available drinking water is badly distributed and comes every day and more polluted by waste from human activities. In less favored areas the population uses will surface reservoirs, like lakes and rivers, but these waters have high turbidity and are unfit for human consumption without adequate pre-treatment. Given the difficulty of treating water by conventional methods this paper aims to study an alternative and sustainable way of treating it to be consumed safely and free factors that favor risk to human health. The proposed treatment was the use of Moringa oleífera seeds as coagulant and flocculant. The experiment was conducted in the laboratories of the Faculty association of higher education and technical caruaruense - asces where water samples were treated with aluminum sulfate and soda ash; and with the seed of moringa. analyzes were conducted turbidity, conductivity, pH and absorbance, oxygen, nitrate, nitrite, phosphate, dissolved ammonia; total and fecal coliforms gross sample, and compared the sample treated with sulphate and soda with the sample treated with moringa, obtaining as a result, the advantages and disadvantages of each treatment. After treatment it was noticed that there was an improvement in water quality and that it could be reused after treatment.
