at a feed rate of 2 0 m 3 hr this water is cascaded toward the prewashing compartments where it is drained while the laundry is transported in counter current direction at the end of the cbw there is a laundry press schematically indicated in fig1 as u201c p u201d where the cleaned laundry is dried the water coming out of this press is recirculated toward the laundry entrance where it is reused furthermore compartment 3 contains a drain indicated by u201c d u201d u201c detergent 1 u201d which is a standard liquid detergent for hard water applications u201c detergent 1 u201d was fed into compartments 1 and 6 at a feed rate of 9 gr kg laundry respectively 3 gr kg laundry u201c detergent 2 u201d which is another liquid detergent u201c detergent 2 u201d was fed into compartment 1 at a feed rate of 2 gr kg laundry in addition an aqueous solution containing 40 bisulphite acting as a neutraliser was dosed into compartment 15 during the tests at a feed rate of 2 0 gr kg laundry in this example experiments were carried out on the cbw shown in fig1 using the experimental method outlined above in order to test the performance of the system of the present invention in the tested system an aqueous solution of savinase being a protease enzyme ex novo was dosed into compartment 1 such that the enzyme dosage was 0 08 gram per kg laundry in addition phthaloylaminoperoxycaproic acid pap was dosed u2014 either contained in an aqueous liquid or as granules u2014 into compartment 7 at a feed rate of 1 66 gram pap kg laundry the performance of.
