Filter Press Case Study: No time to Waste - Emergency Filter Press Repair and Replacement: The client contacted Met-Chem with an immediate need for repair.  Aside from the safety concerns of a damaged press, a filter press cannot run with a broken skeleton.  For this application, waste was continuously generated, which rendered this an emergency situation.

How does a clarifier work? 
A Met-Chem clarifier uses a parallel plate design.  Water is fed into the inlet trough of the flocculation tank.  The wastewater and polymer flocculant are introduced simultaneously in the flocculation mixing chamber, if that option is selected.  The flocculated water then flows over the first baffle, then under the second and finally flows to the body of the clarifier.  The overflow/underflow allows time for the solids to gain size so that they settle out more easily.  The wastewater is then directed to the bottom of the cone and back up through the plate pack.  Some solids will settle as the waste stream makes its way to the clarifier cone.  However, some particulate will be pushed up to the plate packs.  The 60 degree angle of the plates provides a highly effective settling area in a small footprint.  As some solids are forced up to the plate pack they start to settle upon each other gradually becoming heavier and ultimately slide down the plate pack to the clarifier cone.  The clean water overflows from the effluent port and is suitable to proceed to the drain to city sewer or to an inspection tank.  Sometimes a portion or all can be polished and reused.  The clarifier sludge is then pumped from the bottom of the clarifier into a sludge thickening tank to feed a Met-Chem filter press.
