A bleach liquor recovery system for a commercial bleaching apparatus. The recovery system includes a bleaching tank for bleaching loads of textile fabric items with a predetermined batch volume of bleach liquor and a bleach liquor supply system for providing fresh bleach liquor to the bleaching tank. The bleach liquor supply system includes a chemical mixing system for generating the fresh bleach liquor and a bleach liquor injection line for delivering the fresh bleach liquor from the chemical mixing system to the bleaching tank. A bleach liquor recirculation system is connected to the bleaching tank for reclaiming at least a portion of the bleach liquor from the bleaching tank after bleaching a load of textile fabric items and for recycling the reclaimed bleach liquor into successive loads of textile fabric items in the bleaching tank. In the preferred embodiment, a collection tank stores the reclaimed bleach liquor between the successive loads of textile fabric items. A control system is connected to the bleach liquor supply system and the bleach liquor recirculation system for controlling introduction of the fresh bleach liquor and the reclaimed bleach liquor into the bleaching tank.

Bleach liquor recovery system

A multi-stage fluid and chemical recovery system for a textile article commercial bleaching apparatus having a plurality of bleaching tanks, a fluid and chemical supply system for providing fluid and chemicals to the bleaching tanks, a recirculation system connected to the bleaching tanks for reclaiming fluids and chemicals from the bleaching tanks after treating quantities if textile articles and for preselectively recycling the reclaimed fluids and chemicals into successive quantities of textile articles in the bleaching tanks. A control system is connected to the fluid supply system and the fluid recirculation system for initiating and controlling the introduction of new fluids and chemicals and reclaimed fluids and chemicals to the bleaching tanks so that each stage of the system operates continuously and/or simultaneously with the other stages.
