What is on-site generation (OSG)?

OSG gives power to the user

The amount you need, when you need it, and where you need it.

Eliminates storage and handling of hazardous chemicals.

� OSG reduces carbon emissions12% bleach is 88% water. It takes almost 5 deliveries of bulk bleach

to equal the same amount of disinfectant generated by a single

delivery of salt

� Storage footprint reduction

� No disposal of empty chemical containers

► Traditional measurements of the additional oxidant(s) in MOS has not been

successful

• Chlorine is a strong oxidant and interferes with measurement

► There are a small number of known compounds formed from reactions of NaCl

and H2O

Through partnership with academia and internal research,

hydrogen peroxide (H2O2 ) is the additional oxidant in MOS

Microflocculation is a pretreatment mechanism resulting in:

� A reduction in coagulant demand for the same final (filtered water) turbidity

� OR a reduction in final turbidity at the same coagulant demand.

What is Microflocculation?

Pretreatment with MIOX Mixed Oxidants may

induce the microflocculation effect, which improves:

� Coagulation

� Flocculation

� Settling-clarification

� Filtration

These process improvements may:

� Reduce chemical costs

� Reduce system downtime

� Improve system performance

MIOX Customers Report:

� Larger floc that forms more rapidly, even at

colder temperatures

� Heavier floc that is conducive to good settling

compared to chlorine dioxide and chlorine in

pretreatment

� Reductions of up to 40% in required coagulant

and flocculent

� Reductions of disinfection by-product (DBP)

formation due to better organic precursor

removal

� Improved filter run time; reduced down time

Biofilm:� Communities of microorganisms encased within an

extracellular polymeric slime (EPS) matrix living on

surfaces.

� Typically composed of many

species of microorganisms,

including bacteria fungi, algae

and protozoa.

� Difficult to remove once initial

adhesion occurs.

� Found in aqueous environments

and are often resistant to disinfection.

� Can shelter disease-causing microorganisms, such as

Legionella, Listeria, and temperature resistant bacterial

spores.

heavy biofilm in 2 weeks and

eliminated coliform hits

� Indirect − More consistent, lower residual at

Cali, Colombia:

Bottling Plant Replaces Cal-hypo

� Calcium hypochlorite replaced in

2007 with MIOX

� Disinfection is for:

� Beverages (dechlorinate

afterwards)

− Juice

− Carbonated beverage

− Bottled water

� Filter backwash

� Cooling towers

Before MIOX

After MIOX

� Gradual reduction in biofilms in the clearwells and distribution

� Chlorine residual stability allowed lower mixed oxidant solution dosing at the plant

� TTHM and HAA5 concentrations steadily declined

� Conversion from chloramination using chlorine gas and anhydrous ammonia (gas) to FAC as MOS resulted in improved plant safety and chemical cost savings

West Columbia, South Carolina:

Santa Ana Pueblo, New Mexico:

Mixed Oxidant Solution for Wastewater Reuse

� Influent from residential and business districts, the Hyatt Regency Tamaya, and the Star Casino

� WWTP supplies 50,000 gallons at a time to golf course, with remaining irrigation needs met by groundwater

� Disinfection converted in 2007 from competitor’s hypochlorite to MIOX mixed oxidant solution

“MIOX played an important role in helping the Pueblo meet our environmental goals.”

Glenn Tenorio, Chairman of Tribal Utilities Authority

Tamaya Hyatt® Regency, New Mexico:MIOX Treating Pools, Spas, Cooling Tower

� AAA Top 10 Getaway – one of the nation's top family getaways (swimming pools)

� 2008: RIO installed to treat outside pools, whirlpool, indoor spas

� 2011: AE-4 installed to treat cooling tower water

“Safety issues were our biggest motivator. We eliminated the need to manually

transfer 55-gal barrels of chemicals (liquid bleach) each day, which creates a

safer environment all around – it’s a win-win-win.”
