Effectiveness of natural species Coagulation as assistants for clarification of turbid water in times of flood in villages and towns of Huaraz and Callejon de Huaylas

Abstract

The populations that consume water from water sources must guarantee a good quality
for their consumption, for that reason the objective was to evaluate the effectiveness
of natural species as coagulation aids for the clarification of turbid waters that are
generated in times of floods in the LLullan rivers, Paria and Chucchun. The applied
methodology: Collection of coagulants, jar test and determination of optimal doses
and pH. Natural coagulants such as mashua, potato, tara, penca and wheat were used,
which were added to the sample in the jar test, obtaining a dose of 45 mg/l at a
water pH of 7,5 with concentrations of 5,3%, obtaining important removal values for
turbidity parameters and total dissolved solids. When evaluating the efficiency, it was
verified that there is removal of turbidity below the norm, with efficiency values of
89,9% for mashua, potato, tara, penca and wheat coagulants, the coagulants reached
the removal of dissolved solids up to 89% in the tare and a minimum of 13,5% in the
wheat value required by the standard. Therefore, it is possible to use natural inputs
as coagulants for the clarification of surface waters during rainy seasons and to make
them drinkable and suitable for human consumption
