A new filtration apparatus is proposed using a fusible filter medium (FF). The advantages of FF are (1) materials captured by the filter can be recovered by melting the filter and subsequent gravity separation, (2) the filter medium can be recycled, and (3) the latent heat of solidification removed to produce FF is significantly lower than that of vaporization. The filtration can be further simplified and made more cost-efficient using an “ambient-temperature” fusible filter (ATFF). © 2013 American Institute of Chemical Engineers AIChE J, 60: 22–26, 2014
