Abstract: This study presents, a comparative analysis of the LMT and FLMT dimensional equations for sludge filtration. The main objective of this research, study is to develop a comparative analysis of the LTM and FLMT dimension equations for sludge filtration. In this research study, 2 modified equations for sludge filtration processes were developed for use in routine laboratory investigation. This study was completed using laboratory experimentation and mathematical analysis. The 2 general expressions were obtained for the LMT and the FLMT fundamental dimension. Multiple linear regression was used to obtain the required modified sludge filtration equation for LMT and FLMT. The modified filtration equation obtained for LMT show that the volume of filtrate is directly proportional to area of the funnel, applied vacuum, pressure and time of filtration while inversely proportional to specific resistance of sludge and compressibility coefficient. It was discovered that the LMT equation has a high degree of correlation coefficient between measured volume and calculated volumes, this ranges between 0.957-1. The applicability of the 2 modified equations was compared with the already existing equations predicted by Carman and Anazodo’s. The comparative was achieved by evaluating specific resistances of all the existing equations formulated, including the modified LMT and FLMT equation at different pressure points. As a result of this, the specific resistance on pressure, volume, solid contents were verified.
