| Summary: | In the treatment of wastewater, flocculation is one of the most used processes, which aims to eliminate colloidal particles cannot be removed by other methods; Traditionally it has been used aluminum or iron salts and synthetic polymer, which generate little biodegradable sludge; moreover biopolymers, have coagulation and flocculation properties which can remove over 80-90% of solids contaminated; additionally, the use of natural polymers produce sludge increased biodegradability.
The present work analyzes the efficiency of a biopolimer based on 6 endemic plants (Opuntia dilleni, Stenocereus griseus, Cereus forbesii, Melocactus sp. Aloe arborescens and Aloe vera) found at the desertic indian reservation “Kululumana”.
