Re: Pinellas County Utilities Sole Source Contract for THIOGUARD® Technical Grade Magnesium Hydroxide Slurry

Dear Mr. Williams, The following is a summary of the proprietary, patented and trade secret technology surrounding our THIOGUARD® technical grade magnesium hydroxide slurry.

Premier Magnesia has been the industry leader in magnesium hydroxide since our original patent, which pioneered the use of magnesium hydroxide for odor control and alkalinity addiƟon. Innovative scientists and engineers with Premier were the first to discover and develop the controlled systemic application of technical-grade reactive magnesium hydroxide in municipal wastewater systems. We have spent decades trialing and perfecƟng our USA-based product chemistry to provide a consistent and effecƟve end result for our clients.

We have made a significant investment in Ɵme, research, and producƟon to produce the most superior product available because even small variaƟons in chemistry can effect treatment performance and dosage rate significantly. THIOGUARD® is more chemically robust than competing products and therefore can deliver more consistent results at lower dosage rates, ultimately leading to cost savings and increased efficiency. Our technical-grade magnesium hydroxide has the highest purity (MgO), the highest specific surface area for maximum product reactivity, the highest stability for reliable transport and conveyance, and the highest available alkalinity per pound in the marketplace to ensure superior and efficient performance in your system. THIOGUARD® has thus become the most trusted, widely used, and reliable USA-sourced and produced magnesia product to safely control hydrogen sulfide gas, organic odors, corrosion, total gas emissions, FOG (fats, oils, and grease), and provide alkaline treatments to wastewater processes throughout the country.

More recently, Premier has developed practical and cost-effective new intellectual property that helps our customers with a range of treatment strategies that measurably improve conveyance efficiency, reduce total gas emissions, reduce biosolids, enhance nutrient and energy recovery, and better meet federal discharge standards, while minimizing the occurrence of struvite scale. Proper application of this emerging technology solves many of the most vexing problems facing wastewater professionals today.

75 Giles Place Waynesville, NC 28786

Methods involving the use of magnesium hydroxide in municipal wastewater collection systems for total gas production and emission, FOG (fats, oils, grease) accumulation, and in wastewater processes for divalent magnesium (Mg), alkalinity, and struvite control are protected under one or more claims contained in the following patents owned by Premier:

United States Patent No. 11,964,889; Dated: April 23, 2024; Titled: Biosolids quality and dewaterability

United States Patent No. 9,845,258; Dated: December 19, 2017; Titled: Compositions and Methods for Treating Wastewater

United States Patent No. 10,160,674; Dated: December 25, 2018; Titled: Improving Wastewater Pumping and Conveying Efficiency

United States Patent No.10,280,100; Dated: May 7, 2019: Titled: Compositions and Methods for Treating Wastewater and

United States Patent No.10,287,198; Dated: May 14, 2019; Titled: Compositions and Methods for Treating Wastewater.

Copies of the above patents are available online through USPTO or upon request from Premier.

Premier has spent a great deal of effort, research, time, trial, and error, as well as significant funds, to obtain the patent rights described above and to develop a product of the quality that our customers require. We believe the efforts expended to obtain such patents are indicative of the effort our Company will put forward to ensure that our customers receive a competitive, efficient, and high-quality product that will produce superior results.

I hope that this helps in your understanding of Premier’s patent position as well as our superiority of product. Please do not hesitate to contact your Premier Regional Manager Todd Baker at (770) 514 8748 with any questions or concerns.

FORCE MAIN GAS BINDING

PROBLEM STATEMENT:

Pumping and conveying of wastewater from end user through the collection system to wastewater treatment plants can result in negative conditions including gas binding, blockages associated with fats, oils and greases (FOG), and system corrosion. There may be other contributing conditions, but these factors appear to be the greatest contributors to O&M costs including energy consumption, maintenance costs, and Sanitary Sewer Overflows (SSOs).

BACKGROUND:

A collection system line is a unique conveyance system. The transfer of wastewater can result in the release of gases such as O2 – Oxygen, CO2 – Carbon Dioxide, N2 – Nitrogen Gas, H2S – Hydrogen Sulfide, CH4 – Methane, VOCs – Volatile Organic Compounds, and VOSCs – Volatile Organic Sulfur Compounds among others. Some of these gases are drawn into the system through pumping and ventilation, while others are generated within the system either chemically or biologically. These gases can result in the development of gas binding in the system, especially with the utilization of calcium nitrate, as well as contribute to odors and corrosion.

SOLUTION:

THIOGUARD® can overcome these issues by reducing or eliminating gas emissions from wastewater, dissolving FOG blankets and reducing corrosion to pumps and infrastructure. No other product can match THIOGUARD®'s ability to neutralize both collection system surface acid and wastewater acid over short and long distances to and through the wastewater treatment plant.

Not All Magnesium Hydroxide is Created Equal

MgBalance is a custom tailored process technology that systematically adjusts Mg and pH to enhance phosphorus uptake and balance phosphorus and nitrogen, moving struvite through a system without creating scale, and even recover it as a valuable fertilizer.

www.mg-water.com/mg-balance

Our 60% Magnesium Hydroxide Slurry is the most concentrated form of consistent and reliably superior aqueous alkalinity commercially available. It is more chemically robust than competing products and can deliver more consistent results at lower dosage rates, leading to cost savings and increased efficiency.

When modeled and applied appropriately, MgBalance treatment techniques help reduce polymer demand and create biosolids that are not only dewatered better for transportation purposes but potentially have a higher or more desirable reuse value.

Solve the Toughest Challenges in Wastewater Treatment

While most slurries will have the propensity to settle, inferior grades of magnesium hydroxide slurry have been shown to settle as much as 40% more than Premier Magnesia Mg(OH) , creating doubt as to reliable delivery of product into the target system.
