SUGGESTED DOSAGES FOR EOXIDE LQ 0.75% 7500 ppm
To dose 1 ppm on 100 lit of water dose 13.3ml of eoxide Lq 75
A dosage of 5 ppm (mg/l) of 0.75 % concentration = 665 ml chlorine dioxide per 1000 lit of water this is 665 ml of eoxide
To dose 0.5 to 0.3 ppm (mg/l) per liter >27 to 40 ml of chlorine dioxide per 1000 lit of water
The TOC, organic content of the water affects the amount of oxidant (clo2) required to eliminate all bacteria
Previously dosed chlorine gas would have cased biofilm to be very hard and brittle on the inner side of the reservoirs and pipe lines
Suggested dosages for eoxide Lq 85% 8500 ppm
0, 1 ppm is 11.7ml per 1000 lit of water 1ppm = 117ml per 1000 lit
ORP and EOXIDE 75 Chlorine Dioxide:
Chlorine dioxide’s oxidation reduction potential (0.95V) is much lower than chlorine (1.36V) CLO2 oxidation capacity = (5 electrons) this is much greater than that of chlorine only (2 electrons).The oxidation reduction potential (ORP) measures an oxidizer’s strength or speed at which it reacts with an oxidizable material.
Although chlorine dioxide has a low ORP, it is more selective as to the types of oxidizable materials with which it reacts. Chlorine dioxide targets specific organic molecules including cysteine, tyrosine, methoionyl, DNA and RNA. The oxidation capacity indicates that on a molar basis chlorine dioxide has a greater capacity for disinfecting over chlorine. The selectivity and oxidation capacity of chlorine dioxide makes it a stronger oxidative disinfectant than chlorine.
Hereby some info regarding ORP and ClO2 where you can see that 600 Millivolt is reached at a dosage of around 1 ppm. This was at a food processing company. Please keep in mind that the quality of the feed water is important for this and also the temperature can have an effect. We have 2nd customer who is washing with our chlorine dioxide and needs a level of 2, 5 ppm in the water to have 600 Millivolt. He has more organic material in the feed water.
It is possible that the ORP/ppm relation can vary per application and will never be the same. Start with a residual level of 2, 5 ppm of ClO2 in the water and see how it works in practice. In the attachment some info about Agriculture and food where ORP is used most of the times. (600 Millivolt provides a killing time of a few minutes and 700 Millivolt results in a killing time of seconds.)
With no pre mixing tank the quality of the feed water may very and thus the ORP should be monitored by automated dosing equipment
