This study was performed in laboratory scale and consisted of the using of aqueous Opuntia dillenii solution for the clarification of very turbid surface water (Turbidities varying between 186 NTU and 418 NTU). This plant from Cactaceae family was used as a natural coagulant for the different clarification tests. The preliminary phytochemical Screening of the powder of this plant showed that it contains tanins, saponins and mucilages. Flocculation and coagulation tests showed that Opuntia… Expand

Nopal (Opuntia ficus-indica) as a complementary natural coagulant to clarify water
The mucilage of nopal as a coagulant to complement the aluminum sulfate is effective to clarify water, and the pH of the water treated and the conductivity increased in some of the treatments, perhaps due to the primary coagulate. Expand
