Water is essential for life, but not all water is safe to drink.
Contaminants like perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), collectively known as PFAS, have been a growing concern in our water supply. Fortunately, there's a remarkable solution that often goes unnoticed: carbon absorption filters. Here, we'll explore the technology behind carbon absorption filters, how they effectively trap PFAS and their numerous benefits in water treatment.
Understanding Carbon Absorption Technology
Before delving into how carbon filters combat PFAS, let’s review the fundamentals of carbon absorption technology. Activated carbon, the hero in this story, is an incredibly porous material with a vast surface area, typically derived from sources like coconut shells, wood, or coal. This porous structure is what makes activated carbon ideal for trapping contaminants.
1. Activated Carbon's Structure: Think of activated carbon like a sponge, but not just any ordinary sponge – it's a super sponge! At a microscopic level, it's filled with tiny pores and holes, creating a vast and intricate network. Imagine walking through a maze with endless twists and turns – that's what the structure of activated carbon looks like. And why does this matter? Because all those nooks and crannies provide a massive surface area. It's like having a big, open field instead of a cramped room. This extra space is perfect for grabbing onto molecules, kind of like how Velcro sticks to fabric. This process is called adsorption, where molecules stick to the surface of the carbon rather than getting soaked up inside like a regular sponge.
2. Adsorption vs. Absorption: Let's clear up some confusion between two similar-sounding words. Absorption is like when a sponge soaks up water – it goes inside the sponge. But adsorption is different; it's all about what happens on the surface. Imagine you're playing with magnets. When they attract and stick together, that's like adsorption. Activated carbon is a magnet for contaminants. It doesn't suck them in like a vacuum; instead, it attracts them and sticks them onto its surface, where they stay put. So, while absorption is about taking things in, adsorption is about grabbing onto things on the outside.
3. Adsorbent Specificity: One of the remarkable features of activated carbon is its remarkable versatility and ability to adsorb a wide range of contaminants, including volatile organic compounds (VOCs), which are harmful chemicals emitted from products like paints and cleaning supplies, chlorine, commonly found in water disinfection processes, and, most importantly, PFAS, notorious for their widespread presence in water sources and resistance to degradation, making activated carbon an indispensable tool in combating environmental pollution.

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”.

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).

One of the most pressing issues that we face today is the phenomenon of red tide.
Red tide is algae bloom that can cause serious harm to marine life and humans.
In this article, I will explore what red tide is, what causes it, and its impact on Florida. Most importantly, the role of wastewater treatment in helping to prevent it.
What is Red Tide?
Red tide is a natural phenomenon that occurs when certain species of algae grow out of control. These algae produce toxins that harm marine life and humans. The term "red tide" comes from the reddish-brown color that the water takes on when the algae bloom. The bloom can happen in any part of the world in warm, coastal waters.
What Causes Red Tide?
Various factors cause these harmful algae to bloom.
- Changes in water temperature
- Nutrient pollution
- Ocean currents
The most common cause is nutrient pollution. Nutrient pollution occurs when excess nutrients like nitrogen and phosphorus enter the water. These nutrients can come from agricultural runoff, sewage from residential drain fields, inefficient wastewater treatment plants, septic tanks, and fertilizer.
Red Tide Blooms in Florida - History and Impact.
Florida has a long history of deadly algae blooms. The state experiences red tide almost every year, lasting for months.
It devastates the state's marine life, including fish, sea turtles, and dolphins. The algae produce toxins that can kill these animals. The dead fish can wash up on shore, causing beachgoers an unpleasant odor and an eyesore.
How Do These Microscopic Algae Affect Marine Life?
It affects marine life in a variety of ways. The algae's toxins can cause respiratory problems and neurological issues.
With most coastal outbreaks, the loss of marine life is significant. It produces toxins and decreases oxygen levels, another contributing factor to marine animal fatalities. Red tide disrupts the entire ecosystem and has been increasing in both frequencies of outbreaks as well as areas impacted.

3D printing is a technology that has only recently become commercially available.
Progress in the last decade has allowed the equipment to excel tremendously.
3D print technology was started in 1987 by 3D Systems Corporation. The technology gained traction in the early 2010s. 3D printing is a type of additive manufacturing that creates three-dimensional parts. By successively adding material layer by layer until the part is complete.
To create the part, a 3D CAD model is required. The potential of 3D printing has led to a wide variety of technologies on the market. This blog will go into depth on the most prevalent types of 3D printing and their applications.

Odor control in a manufacturing facility is essential.
It prevents potential health risks and discomfort caused by the spread of chemicals, vapors, and fumes. Additionally, excessive vapors can hinder the efficiency of exhaust and natural ventilation systems.
One effective solution for addressing odor issues is the installation of an Odor Control Scrubber Tower. These towers are part of the ventilation system in manufacturing plants and chemical processing facilities.
Odor control scrubbers help to remove noxious fumes and odors from exhaust and air streams. This is an effective way to improve air quality. This process involves utilizing an activated carbon filter and an ionic air filter
Key Considerations for Installing an Odor Control Scrubber Tower:
Health and Safety of Workers:
Industrial environments pose risks of exposure to hazardous fumes and gases for workers. Unhealthy odors emitted in high concentrations can jeopardize their well-being and safety. In some cases, these gases may even be combustible, adding an extra level of danger.
Odor control scrubber towers remove gases from the contaminated air, ensuring a safe working environment. These towers reduce the risk of health issues such as nausea, headaches, allergy symptoms, eye irritation, and loss of consciousness. This helps maintain worker productivity and prevents sickness caused by toxic fumes and gases.

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.

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.

Industrial water systems use water filters to reduce the level of solids in water from:
- Industrial
- Semiconductor
- Manufacturing
- Refining
- Oil and Natural Gas Production Processes
The wastewater may contain harmful chemicals to humans, plants, or animals. Three types of filters are commonly used in industrial settings:
Gravity filters, pressure filters, and constructed wetlands. Pressure filters have two variations: multimedia and higher-pressure micron or cartridge filters. Constructed wetlands or natural filters are not often utilized in industrial processes. Based on the requirements to obtain environmental permits and safeguard the ecosystem.
There are many benefits to pressure filtering systems in industrial wastewater. Pressure filters can remove particles down to 0.3 microns in size. They don't clog up as quickly as other filter types, and it's much faster than other types of filtration methods.
Pressure filtering is also very cost-effective because it uses less energy than other methods. Look no further if you're looking for a high-quality industrial water filter that cuts down on operating costs!
Pressure Filters (Multimedia type) are often used in industrial settings to filter particulates down to 15 microns in size.
They're also very cost-effective due to their energy; pressure filters utilize much less energy than other filtration methods. Pressure filters can include multimedia, a mixture of gravel and sand, multimedia, gravel, sand, and anthracite, or multimedia, which combines gravel, sand, greensand, and anthracite filter media. The variations are dependent on the applications and the need.
