SANITARY SEWAGE TREATMENT USING FILTER FOLLOWED BY COAGULATION WITH MORINGA SEED EXTRACT PREPARED WITH Ca(OH)2

Abstract

Among the forms of primary wastewater treatment, organic flters have stood out due to the high effciency in the removal of pollutants, the low cost of acquisition and the possibility of being submitted to composting after its use.It is aimed was to evaluate the effciency of the fltration process of domestic sewage in gross sawdust, with and without exclusion of the frst two pore volumes, followed by coagulation, using the moringa seed extract prepared with Ca(OH)2. Samples of the raw sewage, subjected to fltration with or without the exclusion of the frst two pore volumes followed by coagulation and only subjected to fltration with or without the exclusion of the frst two pore volumes were assayed for concentration of the TS,TFS, TVS, TSS, FSS, VSS and the values of electrical conductivity and turbidity. In all measured physical variables , except the variables TSS , VSS and turbidity, the processing excluding the frst two pore volumes followed by coagulation (F(E)+C) gave lower values ef?uent compared to treatment in which this was not done (F(SE)+C). Substances solubilized in the organic flter material of the coagulation process hampered by the pitcher seed extract prepared in Ca(OH)2, providing little or no removal effciency of sewage solids.
