MOS Corrosion Study

Analysis of the corrosion rates of mixed
oxidant solution – 70 ppm (CIP solutions 4050 ppm)

Two types of stainless steel materials used:
304 SS and 316 SS

Study protocol was developed using ASTM
guidelines

Fresh oxidant made every 24-48 hours

The largest corrosion rate observed was 0.46
mils-per-year (mpy)

The corrosion rate for 304 SS without
anticorrosion agents was 0.38 mpy

The corrosion rate for 316 SS without
anticorrosion agents was 0.24 mpy

Corrosion was only evident at or above the
waterline
28
Mixed Oxidants in Botle Washing Provides a
Major Savings in Chemical and Energy Costs:

Prior bottle washing operations used a multistep process
where the active component of cleaning was four 5300 gal
tanks of 3-4% NaOH heated to ~60˚C

Pilot testing indicates that this process can be replaced by one
that uses three tanks of MOS at ~1000 ppm FAC and one tank
of 1% NaOH at room temperature
Left: Dirty bottle returned to the
factory with dirt and mold
covering the bottom of the bottle
Right: Bottle cleaned with Mixed
Oxidants with an FAC of 790
ppm
29
Economic Impact of Switching to Mixed Oxidants
Based on fi lling the washer daily with 1,000 ppm Mixed Oxidants and double
water usage, switching to Mixed Oxidants will reduce monthly costs by
$9,919.

Sample CRM1: CRM membrane no pre-carbon
CRM Testing Conclusion
•
•
•
CRM RO membrane can extend membrane life 2-5
times where current RO’s membranes are seeing
premature failure due to chlorine/oxidation attack
Pricing is competitive to TFC membranes
There can be a slight trade off on water quality and
production.
Each application requires a Computer evaluation to ensure quality
and quantity of water produced is acceptable
52
Process or Ingredient Water
•
•
Higher purity water could improve yields, provide
consistent quality and have a return on
investment
Example
–
–
–
–
A leading Bread manufacture used a blended RO water
stream to control inlet batch water quality
Result - while improving yields and product quality, flour
and yeast consumption were significantly reduced
Total plant savings of $120,000 / year on a $60,000
investment
Similar results in Pickle Manufacturing
