Dear Sirs,

i am in order to produce a bottled drinking water, but i still don't have any idea about the accepted range of the ozone un the final product ..
so, please if any have any idea about the acceptable range pleas let me know,

Thanks & regards

This information is from Water and Waste Digest and is readily available from Google along with other pertinent information you may wish to access:

The International Bottled Water Association (IBWA) recommends that ozone be applied in the 1.0 to 2.0 milligram per liter (mg/L) range for a period of four to 10 minutes contact time to safely ensure disinfection. Application at this level helps maintain a 0.1 to 0.4 ppm residual ozone level at the time of bottling. This provides an additional safety factor because the bottles can be disinfected and sanitized while filling it with product.

Water charged with ozone also is suitable for rinsing and cleaning bottles and disinfecting production equipment. This reduces the potential for bacterial growth in unchlorinated water found within the distribution system. It also reduces the amount of clean-in-place (CIP) required to keep the operation disinfected. Many plants have started incorporating an ozonated cap and bottle rinsing system.

Ozone is particularly effective when used in conjunction with other water treatment processes. By using reverse osmosis and nanofiltration or ultrafiltration, organic precursors and inorganics such as bromide can be removed from water before ozone is used. With this configuration, 99 percent of naturally occurring organic materials such as lignin, humic and fulvic acids can be removed, reducing the amount of ozone necessary to disinfect the water. Another benefit is that ozone will not lead to the formation of harmful trihalomethanes (THMs), which are formed when chlorine is added to raw water containing humic materials.
