Abstract EN
The present study aims to optimize the operational conditions in surface water coagulation/flocculation and sedimentation step, besides evaluating the association between seeds of Moringa oleifera Lam.
(M.
oleifera) and the synthetic coagulant aluminium sulphate for surface water treatment.
The assays were performed in Jar Test using surface water from Pirapó River basin, Maringá, PR.
It was observed that the operational conditions affect the coagulation/flocculation and sedimentation process efficiency.
Optimal operational conditions for coagulants association are as follows: rapid mixing velocity (RMV) of 105 rpm, rapid mixing times (RMT) of 1 min, slow mixing velocity (SMV) of 30 rpm, slow mixing times (SMT) of 15 min, and sedimentation time (ST) of 15 min; this enables an improvement in the process, contributing to a reduction in synthetic coagulant aluminium sulphate demand of up to 30%, combined with an increase in M.
oleifera dosage, not affecting the coagulation/flocculation and sedimentation process efficiency, considering the water pH range between 7 and 9.
