Abstract :
The aim of this study was to determine the nature of the foam produced in the process of water purification operations after the pre- ozonation which on a real scale on the pre-ozonation unit of Kuh Sabz water treatment plant in Fars province with has been done by changing the dose of ozone injection and sampling of the foams. The results showed that the foam formed in the ponds they are mainly composed of two parts, hydrophobic and hydrophilic which contains compounds such as turbidity, suspended solids, dissolved organics, surfactants, fats, nitrates, phosphates, cyanobacteria and chlorophyll a. Analysis of foam forming factors in process units showed that aromatic and aliphatic structures of compounds unstable due to reaction with other chemicals added to water and due to the lack of suitable conditions for coagulation and flocculation causes the formation of foam in water treatment process units.
