Abstract (en)
[origin: WO2017066000A1] Embodiments relate generally to methods and systems for bleaching textiles using ozone gas that incorporates a color removal step. In one example, there is provided a hybrid machine that incorporates certain features of a washer, but that also includes an integrated blower for gas distribution inside the machine. There is also provided an ozone dosing control system that allows for maintenance of a constant concentration of ozone in the machine. In one embodiment, the ozone output measured in grams/hour at this constant concentration in conjunction with the weight of product measured being treated may be referred to as the "bleaching factor." There is further provided a wastewater dye removal step, in which ozone is used to clean the water and remove dyes and other colors that may be deposited via denim or other garments.
