Typical Fixed O3 System

CWT CD4000HO 45 grams per hour @ 6%

2 Sequal Workhorse 15C oxygen generators

• 30 SCFH total/90% purity

Signet ORP controller• Maintain 1,000 mV ORP• 4-20 mA signal controlling ozone

output

Rosemount dissolved O3 monitor

Typical System Parameters

• Incoming municipal water– Typical pH of 7-8– Chlorine residual 0.08 to 0.5 ppm

• 0.5 ppm O3 residual (1,000mV ORP) in storage tank

• Applied dosage rate of about 3.3 ppm– Water entering the storage tank is

maintained at a 1.0 ppm residual level

Results

• Maintain ≥ 3 log reduction in mold, yeast and bacteria counts

• Consistent ORP and dissolved ozone readings

• Eliminated wear on fermentation tanks and other stainless steel parts

• Reduced chemical handling• Well water without microbes, residual flavor

or odor effects
