An economically viable process and system for centrally processing multiple loads of laundry with minimum environmental impact. A system and method of laundering whereby successive loads of laundry may be washed while continuously providing effective soil removal comprising at least partially recycled wash water from at least one previous wash cycle. The system and the method of using the same comprises filtering wash water with at least one filter to form wash retentate and wash permeate. The use of wash permeate in successive washes provides for reuse of chemicals and water recovery. A similar arrangement may be used with regard to the rinse water. Advantageously, one embodiment of the invention provides for the use of rinse retentate as make up water in the wash loop which increases water recovery and chemical recovery. Ultimately, the invention can reduce the production of gray water and recover chemicals used in the laundering process.

We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in the rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheeting or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid. The detergent can be used in a variety of high temperature and low temperature automatic warewashing machines including large multizone conveyor machines, or relatively small institutional machines that have a single washing chamber.

Based on the use of a coolant aqueous liquid, usually brine, maintained at low temperature in a reservoir receptacle, as low as −20° C. if the brine is of Sodium chloride or as low as −50° C. if it is of Calcium chloride, applied on the upper surface of the container, positioned horizontally, rotating about its axis, by means of soft jets, during a time which is calculated from the initial and desired temperatures, the temperatures of the cold solution and of the rinsing water and from the temporal coefficient of the packaged beverage, so that the brine glides over its surface drawn by the force of gravity, surrounding it completely through surface tension adherence to the surface of the container located underneath, where it is detached, determining at all times that the brine coats the greater part of the container during the spraying. By substituting the coolant liquid with hot water the rapid heating of packaged beverages is produced.
