Industrial wastewater treatment facilities have been regarded as one of the greenhouse gas (GHG) emission sources. Dissolved air flotation (DAF) process which is carried out to remove fats, oil and grease and carbonaceous materials in a dairy wastewater treatment plant is considered as one of the major GHG generator sources. This paper investigated the GHG emissions of a DAF unit operated in an industrial wastewater treatment facility. The direct emission was estimated from FOG and organic materials removal from wastewater. A new estimation tool was developed, in this study. The indirect emission was figured out from electricity and chemical depletion for DAF process. This study aimed to estimate the greenhouse gas emissions from a dissolved air flotation tank using a new developed model based on IPCC approach. The results showed that electricity depletion was the main resource of the GHG emissions in DAF unit with the value of 3752.35 kg CO2e/d. For the reduction of greenhouse gas emission, electricity consumption should be taken under control.
