Intensive foaming observed during aeration of the aerobic food industry wastewater treatment plant is presented. Thisstudy was conducted to establish the foaming characteristics using a pilot three-phase fluidized bed bioreactor (TPFBB).A fluidization column (0.2 m i.d. and 6 m high) was used. The TPFBB was loaded with variable masses of novel biomasssupport particles (BSP). Wastewater samples collected from a plant processing both vegetable oil (VOPWW) and soap(SPWW) were immediately introduced in the TPFBB for aeration. The characteristics studied include: variation of foamvolume with time, foam multiplicity, foaming and foam collapse rates. The SPWW produced excessive foam volumes at ahigher rate and higher foam multiplicity compared to VOPWW. Dilution, increasing aeration rate or BSP loading led tohigher foaming rate, which decreased with time. Spraying wastewater at the top of the liquid surface minimized foamingrate.
