Filter Press

Filter presses were introduced at the turn of the century and have been around for many years mainly dewatering waste sludge.  Filter press is a separation process, specially employed by solid/liquid separation using the principle of pressure drive, provided by a slurry pump.  Filter press is a fixed volume and batch operation, which simply means that the operation must be stopped to dis-charge the filter cake before the next batch can be started.  The major components of filter press are skeleton and filter pack.  The skeleton holds the filter pack together while pressure is being developed inside the filter chamber.  However, it can only hold a specific volume of solids.  Filter presses are designed for high flexibility, low cake moisture, high filtrate clarity and are highly automated for minimum maintenance and maximum productivity.
