of cycles check u201d feature for each discrete piece of foam being treated this cycle check feature of process 140 may both sense and determine the number of cycles a particular piece of foam has been subjected to chemicals absorption followed by excess chemical expulsion if the number of cycles meets a preset required number of cycles the piece of foam passes on to drying in process 150 if the number of cycles is less than the preset number of cycles the piece of foam is returned to chemicals absorption in process 120 the piece of foam then continues the cycle from thence to excess chemicals expulsion in process 130 until the preset number of cycles processes 120 130 is met during chemical absorption in process 120 treatment chemicals in the chemical treatment fluid are transferred to the foam open cell surfaces thus the treatment chemicals are gradually depleted from the chemical treatment fluid in addition wetted foam pieces that proceed to the drying process 150 entrain at least some carrier fluid that is lost through evaporation in the drying process of course such evaporated carrier fluid may be recovered and recycled if necessary or desirable accordingly sensors may be used in process 210 to determine parameters of the chemical treatment fluid in the container wherein the chemical absorption process 120 takes place these sensors may include a chemical treatment fluid level sensor to detect a decline in such levels.
