Resumen

CHOQUE-QUISPE, David; CHOQUE-QUISPE, Yudith; SOLANO-REYNOSO, Aydeé M.  y  RAMOS-PACHECO, Betsy S.. Capacity flocculant of natural coagulants in water treatment. RTQ [online]. 2018, vol.38, n.2, pp.298-309. ISSN 2224-6185.

The coagulation is the most important process during the water treatment, which includes the removal of species in suspension by means of the addition of chemical coagulants, in which using brings disadvantages associated with high costs of acquisition, production of large volumes of mud and the fact that affect the pH of the treated water. Thus the objective was to evaluate the flocculant capacity of three varieties of Cacti Echinopsis pachanoi, Neoraimondia arequipensis y Opuntia ficus in the artificial wastewater treatment. Doses of 1%, 2%, and 3% coagulant of the three varieties of Cacti extracted with three solvents in the artificial wastewater were applied, observed a significant increase (p-value <0.05) for clarifying capacity and the removal %, with increasing doses of coagulant, the variety San Pedro showed better results. The physicochemical parameters of the treated water as the pH was slightly increasing from 6.61 to 7.58 untreated water, while hardness and alkalinity do not show a significant difference (p-value> 0.05), the DBO of water with coagulant increased with the percentage of application.

Palabras clave : natural coagulant; artificial wastewater; flocculant capacity.
