La coagulación-loculación química complemento de la depuración biológica.

Jean François Audic, Martí Crespi Rosell, Juan Antonio Huertas López

Resum


This paper presents the results from a primary treatment of coagulation-flocculation with low doses of Fe^3+ salt on wastewaters from a slaughter-house, a tannery and a town. The way to determine the concentration of reagents in the primary treatment with a view to decrease the cost of the biological purification and, consequently, to minimize the overall cost of purification is indicated.
