Claim Text:
1. An ozone bleaching system, comprising: an ozone generator; a textile ozone treatment component fluidly coupled to the ozone generator, the textile ozone treatment component comprising a barrel for containing textiles to be treated; and an ozone destruct valve fluidly coupled to an ozone destruct unit, wherein: the textile ozone treatment component comprises an integrated high volume blower component configured for circulating ozonated air through the barrel during a dry bleaching process, the integrated high volume blower component comprising a high volume blower fan and a fan exhaust, the fan exhaust comprising an ozone inlet configured to receive ozone from the ozone generator, wherein in use during a dry bleaching process, the integrated high volume blower component pushes air from the blower fan through the fan exhaust and forces mixed ozonated air created via ozone injected into the ozone inlet mixing with air into the barrel at a high flow rate, causing circulation of ozonated air in the barrel; wherein the textile ozone treatment component comprises a re-circulation inlet leading from the barrel of the textile ozone treatment component to the integrated high volume blower component, wherein ozone injected into the textile ozone treatment component is recirculated by the blower component; and wherein the ozone generator comprises an ozone dosing control system that comprises a first PID loop that controls power delivered to the ozone generator and a second PID loop that controls ozone gas flow rate using a mass flow meter and a proportional valve, wherein the ozone dosing control system delivers a specified ozone dose at a specified gas concentration by weight based on weight of textiles to be treated.
