If the cake does not release, or if any solid <br />material remains, use a plastic spatula to dislodge the remaining material. <br />NOTE. NEVER USE A KNIFE OR SHARP OBJECT TO <br />DISLODGE CAKE MATERIALS AS THIS COULD CUT THE <br />1 FILTER CLOTH. <br />'i After all plates have been separated and the cake removed, clean off any <br />s <br />material that may be stuck to the mating surfaces of the filter plates. <br />When all the plates have been thoroughly cleaned, the filter press may be <br />closed for another filtration cycle. <br />Immediately place the filter press cake into a lined open top steel drum. <br />Secure the drum lid and apply a hazardous waste label and accumulation <br />label. Enter the accumulation start date on the accumulation label. Once <br />full, enter the accumulation end date on the hazardous waste label, The <br />Environmental Technician shall move the drum to the chemical storage <br />area within 3 days of the drum becoming full. <br />The drum will be disposed of within 90 days of its accumulation date by <br />Pollution Control Industries. <br />8.
