MIOX for Potable Water

A direct replacement for chlorine and other biocide

chemicals used in all types of water treatment.

MIOX is On-Site Generation Technology

Generating chemicals on site, on demand is safer, cost effective, and eco-friendly.

Eliminates storage and transportation of hazardous chemicals.

Dramatically improved safety; less liability.

Lifecycle costs much lower than delivered chemicals.

Inherently a “greener” approach with reduced carbon footprint.

What Our Customers Are Saying

INDUSTRIAL &

COMMERCIAL

“Reducing our treatment regimen from 3

different products down to a single mixed

oxidant product (generated on site) has

resulted in substantial treatment chemical

and labor cost savings. We are pleased that

we were able to find a top-notch company

(MIOX) that actually produced an equally

impressive product”

NIPSCO Power Plant

“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.”

Hyatt Regency Tamaya

MUNICIPAL &

MILITARY

“Maintenance costs and labor have been

drastically reduced when compared to the

gas chlorine feed system. The peace of mind

from not having dangerous chlorine gas on-

site was reason enough to switch to on-site

hypochlorite generation.”

EFFECTIVE BIOFILM & ALGAE REMOVAL

Top Menu

Biofilms

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.

shelter disease-causing microorganisms, such as

Legionella, Listeria, and temperature resistant bacterial

spores.

Top Menu

A safe, user-friendly and viable method for

controlling biofilms would have a significant impact

on any industry that control bacterial populations

such as food and beverage CIP, cooling towers,

water distribution systems, and swimming pools.

Controlling Biofilms

Unlike bleach, MIOX removes Pseudomonas putida biofilm including the EPS.

Unchecked biofilm growth

At 5:40

Top Menu

Why MIOX Mixed Oxidant Solution:

Observed effects of MOS on removing biofilm are likely related to its ability to

damage existing EPS

The mechanism is not yet known

MIOX scientists are working with 3rd party researchers to determine the

mechanism

We have observed the effects repeatedly in the field and in the lab

Our current thinking is that the combination of oxidants work synergistically to

break up and dislodge the EPS from the surface, thereby removing the biofilm

THE MICROFLOCCULATION EFECT

An emerging process option, gaining interest for a variety

of applications

MIOX is continuously investigating the use of Mixed

Oxidant Solution (MOS) to induce microflocculation effect

Microflocculation can improve performance and/or reduce

cost

Mixed oxidant solution-induced microflocculation may be

right for your application

MIOX & Microflocculation

A reduction in coagulant demand for the same final

(settled water) turbidity

OR a reduction in final turbidity at the same

coagulant demand.

What is Microflocculation?

Use of mixed oxidant solution in pretreatment can achieve

lower settled turbidity levels and reductions of up to 40% in

coagulant and polymer required.

Customers report faster floc formation and improved

settling due to the quality of the formed floc.

Controlled dosing facilitates microflocculation while leaving

a residual for filter (UF, MF) cleaning and maintenance.

Disinfection by-product (DBP) formation can also be

reduced due to increased removal of NOM during

flocculation.

Benefits of MIOX MOS in Microflocculation

Larger floc that forms more rapidly, even at colder

temperatures

Heavier floc conducive to good settling compared to

chlorine dioxide and chlorine in pre-treatment

Increased filter run times, fewer filter CIP cycles

Formation of a vortex around the rotating paddle

High degree of clarity in both the supernatant and the

water between the floc particles

Very low turbidity of the supernatant (typically < 0.1 NTU)

MIOX Customers Report:

Source: Becker and O’Melia (1996)

Microflocculation May Occur When

• Ca2+ + Mg2+ (as Ca) ÷ Dissolved Organic Carbon (DOC) ≥ 10

• Turbidity ÷ DOC

− > 0.5 NTU/mg C/L if ≥ 2 NTU

− > 1.3 NTU/mg C/L if = 2-10 NTU

− > 2 NTU/mg C/L if > 10 NTU

Microflocculation Effect Can be Predicted

Santa Fe, NM – filter runs extended 50% with less water required

KOA Kampground, MT– cleaning extended from 2-3 days to 3-4

weeks

Las Vegas, NM – backwash cycle doubled from 48 to 96 hours

Hazlet, Saskatchewan – backwash extended from 2X per week to

once per week, with cleaning time reduced from 30 minutes to 15

minutes

Tachikawa pool – cleaning needs have dropped by 2/3, and sand

filters at the end of their life were totally renewed with several

more years expected

MIOX® PROJECT PROFILES: Potable Water Applications

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

average, with all ’06 readings in

compliance.

Pretreatment dose has been reduced

40% to 50% while maintaining the same
