Aldás Ingeniería Coagulation floculation floculation aid natural polymers water purification The aim of this research was to evaluate the coagulating/flocculating characteristics of three natural polymers: green plantain peel starch, orange peel pectin and tamarind seed extracts in three solutions (water, sodium chloride and ammonium acetate), for the purification of raw natural water with turbidity of 5,32 NTU. Natural polymers did not present coagulant activity due to the low turbidity of raw natural water. However, they showed flocculant activity in combination with aluminum sulfate. The optimal combinations of aluminum sulfate mg/L + natural polymer mg/L were: 50+0,2 for starch, 60+0,06 for pectin, 60+0,6 for tamarind extract in water, 60+0,5 for tamarind extract in sodium chloride and 60+0,2 for tamarind extract in ammonium acetate. Removal values of turbidity and color were about 87% and 92 %, respectively. Residual sludge exceeded the maximum permissible limits for discharging to the sewer system. In addition, it showed a toxic effect on the mitotic activity of onion roots with an IC50 of 0,5 to 2 %. 2019 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379858004 https://www.redalyc.org/journal/643/64379858004/ https://www.redalyc.org/journal/643/64379858004/html/ https://www.redalyc.org/journal/643/64379858004/64379858004.epub https://www.redalyc.org/journal/643/64379858004/movil 10.15446/ing.investig.v39n1.69703 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.1 Vol.39 |
