A filter system for filtration of solid particulate materials, in a mineral particle slurry, wherein the solid particulate materials are removed from the liquids during passage of the liquids through a filter media by formation of a cake of particulate material on the filter media while removing the liquids therefrom, the system comprising: a rectangularly shaped support platform having a pair of laterally opposite relatively long side edge surfaces and a pair of laterally opposite relatively short side edge surfaces; a flocculating unit for receiving the slurry to form a flocculated slurry and being mounted on said support platform and said flocculating unit comprising: a flocculator tank means for receiving and treating the slurry; mechanical agitator means mounted in said tank means for providing a zone of intense mechanical agitation in the slurry in said tank means so that the particles in the slurry are subject to intense agitation producing rapid turbulent motion; drive means for creating the zone of intense mechanical agitation in said tank means by rotation of said mechanical agitator means at tip speeds of between about 300 to 600 feet per minute; flocculant feed means mounted in said tank means for introducing into said zone of intense mechanical agitation a diluted polymer flocculant material so that the flocculant activated polymer material is also subject to intense mechanical agitation in the zone of intense mechanical agitation to react rapidly and thoroughly with the particles to form relatively small bead-like floccule particles which may be subsequently filtered from the water at unusually fast rates and produce filter cakes that are characteristically firm and non-sticky for excellent, clean rapid filter cake release and discharge; said flocculator tank means being cylindrical and having a central flow separation means provided by a cylindrical side wall with an upper inlet opening located adjacent the upper end portion of the tank means and a lower outlet opening adjacent the lower end portion of the tank means and said agitator means being coaxially mounted adjacent the lower outlet opening for causing flow of the slurry downwardly in said central flow separation means from said upper inlet opening to said lower outlet opening and into contact with said agitator means; a vacuum filter unit having a central longitudinal axis of rotation mounted on a central portion of said support platform with said central longitudinal axis of rotation parallel to said relatively short side edge surfaces; slurry conduit means for transferring said flocculated slurry containing said head-like floccule particles from said flocculating unit to said vacuum filter unit; a filter cake and an air suspension of filtrate formed by said vacuum filter unit; a vacuum receiver means mounted on said support platform adjacent and separated from and in space relationship to one end of said vacuum filter unit for directly receiving said air suspension of filtrate from said vacuum filter unit and for separating said air suspension of filtrate into air and filtrate; air-filtrate conduit means for transferring said air suspension of filtrate from said vacuum filter unit to said vacuum receiver means; air-filtrate inlet means on said vacuum receiver means for supplying said air suspension of filtrate to said vacuum receiver means; filtrate outlet means on said vacuum receiver means to remove filtrate therefrom; air outlet means on said vacuum receiver means to remove air therefrom; and vacuum pump generating means mounted on said support platform and being connected to said air outlet means for forming a vacuum in said vacuum receiver means and in said vacuum filter unit.
