Agenda 06/11/2013 Item #16C16/11/2013 16.C.1.
EXECUTIVE SUMMARY
Recommendation to waive competition and standardize the procurement of the odor control
proprietary chemical Aktivox provided by Siemens Corporation.
OBJECTIVE: To procure the proprietary odor control chemical Aktivox, that is utilized in daily
operations to reduce odorous gases within the wastewater treatment facilities and neighboring
residential areas.
CONSIDERATIONS: Aktivox is a proven strategy in Collier County for addressing odors at the
Wastewater Reclamation Facilities. This product is essential for compliance with Environmental
Protection Agency Regulations and Collier County's Good Neighbor Policy. Aktivox has proven
to be the best solution for the County's wastewater system because it has the ability to rapidly
address odors and gases on contact. Other vendors market odor reducing solutions but those
solutions do not have the rapid response rate of Aktivox's proprietary solution developed by
Occidental Petroleum Corporation.
This product will be used extensively over the next 18 months to address odor abatement at the
South Wastewater Reclamation Facility. It will support the capital improvement project in
progress that encompasses replacing and reconfiguring the odor control scrubbers at the plant.
Odor control scrubbers are an additional technique used at the reclamation facilities to reduce
and eliminate sewer odors. During this improvement project, Aktivox will be used extensively to
mitigate odors while the scrubbers are out of operation.
Purchasing staff have validated through Occidental Petroleum Corporation that Siemens Industry
is the sole distributor of this product. Staff requests that the Board waives formal competition
pursuant to Purchasing Policy Section V.A. 2 and 4, which provides for:
2. "Single source purchases (pursuant to subsection C);"
4. "Where it is determined to be in the best interests of the County to do so."
The waiver should be granted in this instance because the item is the "only one available that can
properly perform the intended function(s)" (Purchasing Policy V.C.1), and it is in the County's
best interest to waive formal competition and procure the product from the sole provider Siemens
Industry.
FISCAL IMPACT: Funding is available in, and is consistent with, the FY13 Operating Budget
approved by the Board of County Commissioners on September 20, 2012. The source of funding
is the Water -Sewer District Operating Fund (408). This will be a reoccurring operational cost
over the next (4) four years with an estimated annual spend of $80,000 - $100,000 for the South
Wastewater Reclamation Facility. This estimation does not include unforeseen needs at other
facilities such as Orange Tree over the next (4) four years. Additional facilities requiring Aktivox
for odor control will be allocated in their respective budgets encompassed under this executive
summary.

Odor Control with Aktivox@
Introduction
Aktivox@ is a proprietary, powerful, non - chlorinating
oxidant that effectively controls odors and corrosion
associated with wastewater collection and treatment.
Aktivox@ reacts virtually instantaneously with
sulfides, and other odorous compounds, making it an
ideal deodorizer for both solids pressing operations,
wastewater pump stations and ponds and lagoons.
As an added benefit, Aktivox@ provides residual odor
control that lasts for hours after addition.
Application Description
Sulfides are produced by both biological and chemical
action. They are produced biologically by anaerobic
bacteria and chemically by many industries including
the chemical, petroleum, paper, and textile industries.
Many systems provide an environment that can
promote the growth of a healthy biological
community. Hydrogen sulfide formation in wastewater
systems occurs primarily in the gelatinous slime layer
(biofilm) that accumulates on pipe walls and in the
sludge blankets of clarifiers and other solids
processing units. The rate of sulfide production is
dependent upon the concentrations of sulfate ions,
organic matter, and dissolved oxygen, as well as
other factors such as pH, temperature,

retention time, stream velocity, and surface area.
Hydrogen sulfide is naturally converted to sulfuric
acid which is corrosive towards steel and concrete,
therefore its control results in increased life and lower
maintenance cost for facilities and piping. In addition,
worker safety is of concern as hydrogen sulfide is
extremely toxic at levels above 500 ppm which can
be reached in confined spaces.
Treatment Alternatives
Sulfide can be removed from a system by
precipitation with iron or by oxidization. Various
oxidizers including chlorine, hydrogen peroxide, and
potassium permanganate are commonly used for
oxidation of sulfide. Different treatment strategies are
required depending on the application. Aktivox® is
preferred where alternative oxidants are not effective
such as when rapid destruction of sulfide is important
(Figure B), or the formation of halogenated
byproducts prevents treatment with chlorine.
Aktivox@ reacts preferentially with hydrogen sulfide to
form elemental sulfur (Figure A). Aktivox@ will form
soluble sulfate if applied in excess.

Typical Applications include:
• Belt filter presses
• Wastewater force mains
• Septage and leachate
• Clarifiers
• Ponds and Lagoons
• Wastewater pump stations
• Gravity collection lines
• Odor scrubbers
• Headworks facilities
Advantages of Aktivox®
• Near instantaneous reaction — Aktivox® is a fast
reacting oxidant able to control wastewater odors
at or near their source (Figure B). It is effective
for use on belt filter presses, headworks
structures, or remote pump stations where
upstream chemical addition would be costly or
impractical.
• High selectivity — Aktivox® reacts preferentially
with sulfide and related organic odors. Effective
dose ratios are very near stoichiometry (1.3:1
w /w). Unlike hypochlorite, Aktivox® does not
react with ammonia nor does it form chlorinated
organics.
• Long duration control — As a selective oxidizer,
Aktivox® will not readily decompose within
wastewater as rapidly as hydrogen peroxide or
hypochlorite (Figure C). It can be applied several
hours upstream of the point at which the odors
occur. Significantly, long- duration control is
provided at costs generally less than nitrate.
Feed Requirements
The required dosages will vary with water conditions,
the severity of contamination, and the degree of
control desired. Typically one gallon of 25% active
Aktivox® will eliminate 2.0 pounds of hydrogen
sulfide.
Higher dose rates may be required in solids
processing operations or where retention times are
unusually long.
For industrial applications involving once through
systems or systems where treated water may enter a
US waterway, the concentration of residual chlorite
ion should be monitored and controlled such that it
does not exceed the requirements of the NPDES
permit. All discharges must be in compliance with
local, state and federal regulations.
For more information on dosage requirements
specific to your application, contact your OxyChem
representative.
Method of Feed
Aktivox® may be applied using basic chemical
metering pumps and equipment either at the odor
source (as in belt filter presses or wastewater pump
stations) or hours before odor generation occurs (as
in lagoons, clarifiers and wastewater force mains).
Chlorite Analysis
Residual chlorite ion concentrations should be
determined by substantiated methods, which are
specific for sodium chlorite. Three such methods are
described in detail in Standard Methods for the
Examination of Water and Wastewater'.

RE: AKTIVOX® AND VX 456®
Dear Johnny:
Siemens is pleased to provide the following information regarding our AKTIVOX'�' and VX 456®
products:
AKTIVOX is a unique, buffered formulation containing 25% active sodium chlorite solution
designed to yield a sustained release of chlorine dioxide to control odor - causing sulfides and related
oxidizable compounds in industrial and municipal wastewater systems. AKTIVOX is a selective
oxidant with specificity to sulfides and related organic odor causing compounds. AKTIVOX does
not form chlorinated organics, and is fast - reacting. Non - buffered sodium chlorite solution would not
provide the speed of reaction nor the specificity to sulfide and related odor compounds needed for
wastewater odor control. The unique AKTIVOX formulation is proprietary to Siemens for use in
wastewater odor treatment.
VX 456 is a proprietary mixed oxidant product designed to remove and control malodors in waste
streams. VX 456 reacts rapidly with sulfides and other odor - causing compounds commonly found in
wastes and continues to control odors for an extended period of time (up to 72 hours). VX 456 does
not contribute to solids formation and does not interfere with further processing of waste. VX 456
contains selective oxidants with specificity to sulfides and related organic odor causing compounds.
VX 456 does not form chlorinated organics, is fast - reacting, and has long duration control. VX 456
is proprietary to Siemens for use in wastewater odor treatment. U.S. Patent 5,984,993 applies to the
