Decarbonation of Water

Posted by Anthony DeLoach, President on Jun 20, 2023 11:26:13 AM

Requires an application commonly referred to as either “Degasification” or "Decarbonation" and it requires the use of a piece of water treatment equipment called either a “degasifier” or a “decarbonator”.

Both of these are similar in nature and are designed for Carbon Dioxide (CO2) removal from the incoming water. A properly designed decarbonator can remove 99.99% of the free carbon dioxide gas that is present in the water stream. One of the primary reasons for utilizing a decarbonator or degasifier for the removal of carbon dioxide gas is the raise the pH of the water without the need to add caustic. resulting in high-purity water.

The other reason is the remove the CO2 prior to treating the water with Ion Exchange which utilizes Anion or Cation resins to reduce the regeneration cycles for the resin beds. High concentrations of CO2 consume the ion charge within the resins and require more frequent regeneration cycles. The difference between anion and cation resins is that one is positively charged (anion) and the other is negatively charged (cation), cation resins, attract positive ions with their negative charge.

The term decarbonation describes the process of the removal of suspended gas or the conversion of carbonic acids into free Carbon Dioxide. Carbonic Acid (H2CO3) is stable at normal ambient anhydrous conditions. However, Carbonic Acid decomposes when not stable and in the presence of any water molecules to form carbon dioxide (CO2).  The Carbonic acid breaks down when present in water and it is converted to a gas based upon certain conditions. It is common to have CO2 present in water requiring a decarbonation process when utilizing certain types of water filtration such as membrane filtration with reverse osmosis or it can be present when the need to adjust pH is required. When removing (CO2) the process is often referred to as “Decarbonation”, when removing (H2S) Hydrogen Sulfide the process is often referred to as “Degasification”.

Decarbonation the Removal of CO2 from Water

Posted by Anthony DeLoach, President on Jun 19, 2023 3:10:22 PM

The Basics of Water Decarbonation

and the removal of carbon dioxide (CO2). The need to remove (CO2) is essential in most Aquaculture, Municipal, Industrial, and Food & Beverage Processes To understand you must familiarize yourself with Henry’s Law.

Henry's Law defines the method and proportional relationship between the amount of a gas in a solution in relation to the gas's partial pressure in the atmosphere. Often you will see and hear various terms like degasification, decarbonation, aeration, and even air stripping when discussing the removal of dissolved gases and other convertible elements from water. Understanding the impacts that Carbon Dioxide (CO2) can have on both equipment and aquatic life provides the basic reasons why the need to decarbonate water, exists. Carbon Dioxide (CO2) can exist naturally in the raw water supply or be the result of ph control and balance. In either case, the process called Decarbonation or Degasification provides the most cost-effective and efficient manner to reduce or tally remove (CO2) from the water. In addition to Carbon Dioxide (CO2), water can contain a variety of other contaminants that may impact the removal efficiency of the Carbon Dioxide. A variety of elements as well as dissolved gases such as oxygen, nitrogen, and carbon dioxide (CO2). A full analytical review of the water chemistry is required to properly design and size the “Water Treatment” process.

Breaking the bonds in water releases a dissolved gas

such as carbon dioxide (CO2) you must change the conditions of the vapor pressure surrounding the gas and allow the gas to be removed.  There are many variables to consider when designing or calculating the “means and methods” of the removal of carbon dioxide (CO2). When I refer to the means and methods. I am referring to the design of a decarbonator and its components. The means equals the size and type (Hydraulic load) of the decarbonator and the “method” equals the additional variables such as the cubic foot of airflow (CFM) and “Ratio” of the air to water to accomplish the proportional condition needed to remove the carbon dioxide (CO2).

What Is Water Turbidity?

Posted by Anthony DeLoach, President on Mar 18, 2022 1:05:00 PM

Water turbidity refers to how transparent or translucent the water is when examining or testing it for any use.

 Water turbidity can impact food and beverage, municipal, industrial, and aquaculture operations. Turbidity is caused by suspended or dissolved particles in the water that scatter light which causes the water to appear cloudy or even murky.

Different particles can cause turbidity, including sediments such as silts and clay, fine inorganic or organic matter, algae or soluble colored organic compounds, and microscopic organisms. Turbidity is measured in a value referred to as NTU, which means Nephelometric Turbidity Unit. The EPA requires a turbidity level no higher than 0.3 NTU in the USA, and if a member of the partnership of safe drinking water, then the level must not exceed 0.1 NTU.

High turbidity can create habitats for other harmful elements, such as bacteria or metals, that can accumulate onto the particles. This increases the health risk for a potable water system. In aquaculture operations, increased turbidity from silts and sediments can harm and harm marine life, so it must be removed to safe levels. For the food and beverage industry, the impact of high turbidity can be both a safety concern and a visual and noticeable quality concern because if the turbidity is high, it can alter the physical look of the final product, for example, a distillery.

Unraveling the Impact of Forever Chemicals in Water

Posted by Anthony DeLoach, President on Feb 22, 2022 1:02:58 PM

The EPA and other world health organizations have sounded the alarm on the dangers and health impacts of being exposed to per- and polyfluoroalkyl substances (PFASs & PFOAs) also known as the forever chemicals.

In response, federal and state regulators are adopting new water quality guidelines and laws to address these contaminants in our drinking water systems and groundwater pollution. It's a pervasive issue, as PFASs can be found in various types and over 4,700 different variations, each with at least three polyfluorinated carbon atoms.

With more than 10,000 types of PFASs introduced into products, it's no wonder that the quality of drinking water in the USA and other countries has been compromised. But what exactly are PFASs? These are fluorinated substances that contain at least one fully fluorinated methyl or methylene carbon atom. While they do not contain atoms like hydrogen, chlorine, bromine, or iodine, any chemical with a perfluorinated (CF3) or perfluorinated (CF2) component falls under the PFAS category. However, there are a few exceptions.

PFASs can be further classified into subgroups such as surfactants, perfluorosulfonic acids, perfluorooctane sulfonic acids, perfluorocarboxylic acids, and perfluorooctanoic acids (commonly referred to as PFOSs and PFOAs). These persistent organic pollutants, also known as "forever chemicals," pose a significant challenge due to their resistance to environmental degradation. As a result, they are found in humans, animals, and water supplies across the USA.

What is Water Demineralization?

Posted by Anthony DeLoach, President on Jan 27, 2022 12:54:16 PM

Water demineralization is also called deionization and is a process known as “Ion Exchange.”

In simple terms, water demineralization is “Water Purification.” The process involves removing dissolved ionic mineral solids from a feed-water process, typically for “Industrial” water applications. Still, it can also be utilized to remove dissolved solids from a water process for “Aquaculture,” “Food and Beverage,” and the “Municipal” markets.

Why is demineralization utilized? It can remove dissolved solids to near distilled water quality at a much lower capital and operational cost than other treatment processes such as membrane softening (Reverse Osmosis). Demineralization applies the science known as “Ion Exchange,” which attracts negative and positive charged ions and allows either to attach themselves to a negative ion depending on their respective current negative or positive charge during what is known as a resin cycle. In other technical articles, we will explore and go into more specific details on the science of the ion exchange process. Water that has dissolved salts and minerals has ions, either negatively charged ions known as “Anions” or positively charged ions known as “Cations.” To treat the water and remove these contaminants, the ions in the water are attracted to counter-ions, which have a negative charge. In a demineralization treatment process, there are pressure vessels that hold resin beads which are typically made of plastic. The beads are made from a plastic material with an ionic functional group that allows them to hold and maintain an electrostatic electrical charge. Some of these resin groups are negatively charged, referred to as “Anion” resins, while others hold a positive charge and are called “Cations” resins.

There are different applications to apply Ion exchange technologies, which is why you will often hear different terminology interchanged like deionization and demineralization. The raw water quality and the specific application will dictate the type of ion exchange process needed. For example, if the water contains a high level of hardness, the water will most likely contain Ca2+ or Mg2+ dissolved solids possessing a positive charge. To replace these hard ions, it is typical to utilize a resin bed with a salt ion like Na+. As the water passes over the resin bead material within the pressure vessel. The hard ions are replaced with the salt ion; therefore, all the hardness within the water is removed. However, the water will now contain a higher concentration of sodium ions, and this must be considered during the evaluation and selection process of the type of resin material to utilize for the specific application. If the water application requires high purity and the removal of as many solids as possible, then the term or process selected is referred to as demineralization.

Advancements in Per and Polyfluorinated Substances  Removal Technology

Posted by Anthony DeLoach, President on Dec 14, 2021 1:00:00 PM

Per- and polyfluorinated substances (PFAS), known as "forever chemicals," have long been utilized in various consumer products due to their exceptional properties.

However, the challenge lies in effectively treating or eliminating PFAS once they enter the environment or water supply. This blog will focus on the technological advancements in removing PFAS and perfluorooctanoic acids (PFOAs) from water sources. By exploring different treatment methods, such as activated carbon absorption, ion exchange resins, and reverse osmosis, and simply avoiding PFOA and PFOS, we can better understand the available options for mitigating these persistent chemicals in water.

Activated Carbon Absorption

One of the earliest technologies employed for PFAS removal is activated carbon absorption. This method involves the use of specially treated carbon materials that effectively adsorb PFAS compounds from water sources. The activated carbon's large surface area and porous structure allow it to trap and retain PFAS molecules. This technology has proven effective in removing PFAS, including PFOAs, from drinking water and environmental sources. However, periodic treatment and regeneration of the activated carbon are necessary to maintain its efficacy.

Chemical Compatibility

Posted by Matthew C. Mossman P.E. on Oct 29, 2021 1:01:00 PM

In process control systems, it is often required to handle fluids that have a harsh chemical nature. In these cases, it is necessary to be aware of material-chemical compatibility. Chemical compatibility is a general term referring to the way a specific chemical interacts with a specific material. This information is taken into consideration when selecting materials for construction for tanks, valves, pipework, tubing, and other devices that may encounter harsh chemicals. Common chemical types that are used in process systems are acids, bases, corrosives and oxidizers, and hydrocarbons. Typical chemical-resistant materials include natural and synthetic rubbers, vinyl polymers, fluoropolymers, and stainless steel. In order to determine which materials are compatible with certain chemicals, a chemical compatibility chart is often used. A chemical compatibility chart contains tabulated data about how a given material interacts with a given chemical.

Often, the manufacturer of the equipment or material in question will have their own compatibility chart for their specific goods. Most compatibility charts will have the same type of information. Materials will be categorized along one axis of the table, with fluids or gasses categorized along the other axis. At the intersection of a material with a fluid, you will find an indication of the level of compatibility. Some charts will use an A-F categorization, others may use a more graphical style. Most charts will be accompanied by a key or guide that explains how to use the table. There may also be multiple concentration levels and temperature ranges for a given fluid in cases where the distinction makes a difference with compatibility.
