MATH OF CDS

Thanks, Zoray - I went in and fixed it. Goodness knows when we will get all the links edited to the new g2cforum addy. If anyone sees one and wants me to fix it, please let me know.

How to dilute CDS

It has been postulated by MMS team that
One Standard DOSE of CDS is 1 ml of 3 000 ppm CDS
(equivalent to 3 drops of activated MMS1 = 3 mg ClO2)

Then simple formula is valid:

Volume of CDS [ml] for 1 dose = 3000 / CDS Concentration [ppm]

Example:
We have 1500 ppm stock solution.
Volume of CDS we need is 3000/1500 = 2 ml
If we dilute this 2 ml with water to total volume 125 ml we have one dose of CDS with concentration 24 ppm and dose 3 mg ClO₂


Let's start to distinguish between CONCENTRATION and DOSE

We are accustomed to using ppm for expression the concentration of CDS. It is OK. But when we use the same unit (ppm) for a dose, it is incorrect and might be confusing.
ppm - one part per million - denotes one part per 1 000 000 parts.
One kilogram (kg) = 1 000 grams (g) = 1 000 000 miligrams (mg).
3 000 ppm CDS means that there are 3 000 mg (miligrams) of chlorine dioxide in 1 000 000 mg (=1000 g =1 kg) of solution. At low concentrations and normal temperature we can take that 1 kg = 1 liter and CDS 3 000 ppm is then approximately 3 000 mg of chlorine dioxide in 1 liter of CDS.

It has been postulated by MMS team that

one Standard DOSE of CDS (equivalent to 3 drops of activated MMS1) is 1 ml of 3 000 ppm CDS

usually diluted in 125 ml (4 fl oz) of water to circa 25 ppm concentration.

From above:
in 1 liter of 3 000 ppm CDS is 3 000 mg of chlorine dioxide,
in 1 ml of 3 000 ppm CDS is 3 mg of chlorine dioxide

One Standard DOSE is 3 mg of chlorine dioxide in 125 ml (4 fl oz) of water

If we dilute this amount (3 mg) to any volume of water the concentration is changed but the dose remains the same. The concentration of 25 ppm (3 mg of ClO2 in 125 ml of water) was established as the optimal one in regards of the CDS taste.

The dimension of
• Concentration in our case is [mg/liter] (weight/volume)
• Dose is [mg] (weight)

There are simple relations between Dose, Concentration and Volume

Dose [mg] = Concentration [ppm] x Volume [liter]
Concentration [ppm] = Dose [mg] / Volume [liter]
Volume [liter] = Dose [mg] / Concentration [ppm] or

Volume [ml] = ( Dose [mg] / Concentration [ppm]) x 1000
1 Dose = 3 mg ClO₂

So that
Volume [ml] = 3 [mg] / Concentration [ppm] x 1000 = 3000 / Concentration [ppm] - above mentioned formula.
