Study and Compression of effect of Acid cracking Pretreatments and chemical coagulation with chloroferric on Increasing Effeciency of Olive Mill Wastewater Photocatalysis Treatment
MetadataShow full item record
In this work, ferric coagulation and acid cracking as olive mill wastewater (OMW) pretreatments during photocatalysis process were compared in batch recirculation reactor. Because of ferric ions influence, ferric coagulation has preference over acid cracking. Ferric ions influence on intensification of penolic components absorption on TiO2 surface in initial and oxidize organic pollutant during photocatalysis treatment. In this investigation, COD and total phenolic (TPh) reduction were studied with altering TiO2 concentration and pH as main effects. The results revealed that the percentage removals of COD and TPh in ferric coagulation were 69.24% and 88.16% respectively, whereas these percentage removals in acid cracking were 62.66% and 57.87% respectively.
