Water, as a necessary liquid for life and an essential source of industries, must be used and recycled in aregular cycle. Water filtration is a special area that is being developed by relevant experts. In many areasof activity, the most critical goal is to increase the separation and filtration efficiency. The efficiency ofan effective filtration system chiefly depends on the selection of a suitable porous filter. Woven fabricsare utilized as filters in liquid filtration. In this research, a water filtration unit was carefully designed andassembled to evaluate woven polyester fabric’s filtration efficiency in a standard procedure. The particlesize distribution in water was between 100-140 μm. The woven polyester fabrics, that were differed inweft density and weave, were produced by a projectile weaving machine. The samples were used as filterson both sides of the back and face of the fabric. After the separation process, the filtered water turbidityand the filtration efficiency for each sample were evaluated. Statistical analysis of the results showed thatthere was a significant difference in filtration efficiency when using low-density fabric samples on bothsides of the back and face of the fabric. The water filtration efficiency when using the backside of thesamples is higher than that when using the face side. In fabric filters with different weave structures anddensities, it was detected that the filtration efficiency is not significantly the same. Finally, according tothe ultimate performance of fabric filters in the filtration process, the samples were classified.
