Modelling of Fat Oil and Grease (FOG) and Total Suspended Solid (TSS) Removal Rate on Dissolved Air Flotation Process Using Multiple Linear Regression

In the wastewater treatment process, floatation unit have been developed to remove particles or flocs that tend be difficult settle, such as fat oil and grease (FOG) total suspended solids (TSS). Flotation is a operation can separate liquid phase solid from phase, this occur due presence of saturated air which mixed so it contains fine bubbles help separated. This research was conducted by treating industrial area waste water using flotation method with pilot plant system. order work optimally, there are important parameters in debit recirculation. study aims model removal rate FOG TSS process multiple linear regression. From modeling results, two models separately. R square value obtained for 0.678 0.214 consecutively.
