How to Remove Nanoparticles from Your Drinking Water‍

Posted by Anthony DeLoach, President on Jul 22, 2022 1:14:33 PM

If you’ve been reading the news lately, you know nanoparticles are not so great. In everything from cosmetics to water filters, nanoparticles have been shown to cause various health problems. But what exactly are nanoparticles, and how can you protect yourself from their harmful effects? Let’s answer these questions and more with this quick guide on removing nanoparticles from your drinking water.

What are Nanoparticles?

Nano is a prefix that’s used to indicate how small something is. In the case of nanoparticles, it means particles less than 100 nanometers. Water filters that use nanoparticles are generally around 0.2 to 0.3 microns or 2,000 to 3,000 nanometers. That’s pretty small. There are some health concerns with nanoparticles. When ingested, they can cause inflammatory reactions in the body, disrupt normal organ function, and lead to a buildup of fluids in the lungs or other organs. A 2017 study found that the number of nanoparticles in drinking water is higher than expected and that using carbon filtration may make some nanoparticles more likely to leach into the water.

Where Are Nanoparticles Found?

Nanoparticles are found in a lot of modern products. Their small size makes them ideal for air and water filters, sunscreens, and cosmetics. It’s important to note that not all nanoparticles are harmful. Some are beneficial. Nanoparticles of silver are often added to water filters to help remove bacteria and other contaminants from drinking water. There are a few places where nanoparticles are most often found. - In water filters - Nanoparticles are often added to water filters to help remove bacteria and harmful contaminants. - In sunscreens - Some sunscreen products contain nanoparticles of zinc oxide, titanium dioxide, and other minerals that provide broad UV protection. - In cosmetics - Many makeups, lip balms, and other beauty products contain nanoparticles of iron, titanium dioxide, zinc oxide, and other minerals that help preserve the product and provide color.

Treating Noxious Fumes with an Odor Control Scrubber.

Posted by Anthony DeLoach, President on May 24, 2022 1:00:00 PM

A manufacturing facility cannot ignore the importance of odor control.

 

The smell from chemicals, vapors, and fumes can spread quickly in a small area. They cause discomfort to workers and pose health risks to them. In addition to that, excess vapors directly impact the efficiency of exhaust or natural ventilation systems. For example, an odor control scrubber tower is an additional layer in the ventilation system of a manufacturing plant or chemical processing facility that has issues with odors. These towers effectively remove noxious fumes and odors from ventilation exhaust streams using an activated carbon filter and an ionic air filter.

 

Reasons why you should consider installing an Odor Control Scrubber Tower :

 

Health & safety of workers.

 

Everyone working in an industrial environment, either directly or indirectly, is at risk of exposure to hazardous fumes and gases. At times, high concentrations of these gases may be emitted into the atmosphere in the form of unhealthy odors, putting the health and safety of the workers at risk. These gases may even be combustible in some cases, posing a significant threat to workers. The purpose of an odor control scrubber tower is to remove these gases from the contaminated air stream and help the workers stay safe. In addition, it reduces the risk of health issues such as nausea, headaches, loss of consciousness, allergy symptoms, dizziness, and many more. It also prevents workers from missing their daily performance targets due to sickness caused by toxic fumes.

 

Pro-environment step.

 

Although it is vital to protect the workers from exposure to harmful fumes, it is also essential to protect the environment. Odor control scrubbers are used in petrochemical refining, pharmaceutical, food & beverage, paper, mining, chemical, and pharmaceutical industries. Therefore, it is crucial to choose the right type of scrubber that suits your industry’s requirements. The right choice of equipment also protects the environment as it helps reduce operational costs and maintenance supervision. It also protects the environment because it produces minimal sludge and reduces the risk of corrosion.

PFAS in Drinking Water

Posted by Anthony DeLoach, President on May 4, 2022 1:05:00 PM

If you’ve been following the news, you know that there’s a growing problem with PFAS (per- and polyfluoroalkyl substances).

 

These man-made chemicals are found in everything from clothing to food packaging. While they are inexpensive and stable in products, some of these substances tend to break down into other substances, such as PFAS-methyl tetrahydrofuran. PFASs have been discovered in drinking water across the country, including in parts of the country with very high water tables. As a result, it’s important to learn how to remove contaminants from your drinking water. What should you do if you suspect that there’s a problem with your water? Check the source of the water, test it, and treat it if necessary.

Follow these steps to remove contaminants from your drinking water.

Test Your Water

Although it’s important to know how to remove contaminants in general, it’s even more important to know how to test your water for contamination. A water test kit can help you determine whether there are contaminants in your water and whether they are at a dangerous level. You can purchase water test kits at most grocery stores, hardware stores, and online retailers. Generally, these kits come with the standard set of tests for a home water filtration system, but they also often include tests for certain contaminants. Use these tests to determine whether your water is safe to drink or not. If your water contains contaminants, you need to remove them from your water source. This can be done by digging a deeper well, installing a water filtration system, or getting a water purification system. If your water does not contain contaminants, you don’t need to do anything except continue drinking your water.

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 given 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 types of particles can cause turbidity, and they include sediments such as silts and clay, very 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 be harmful and detrimental to 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.

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 the 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.

Benefits of Pressure Filters for Industrial Water

Posted by Anthony DeLoach, President on Jan 4, 2022 1:00:00 PM

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.

Flow Measurement in Water Systems

Posted by Matthew C. Mossman P.E. on Sep 28, 2021 11:45:00 AM

In water treatment systems it is often important to measure the rate at which water is flowing through the system. Data from flow measurement devices can be used to control chemical dosing, set pump speeds, control filter loading rates, inform maintenance programs, and other tasks necessary for operation of a water treatment facility or on key components such as Degasification and Decarbonation systems or Biological Odor Control Systems. As with most types of instrumentation, there is an array of technologies that can be used for the task, each one with various strengths and optimal applications. For modern electronically controlled systems, the most common types of flow sensors used are axial turbine flowmeters, paddlewheel flowmeters, differential pressure / orifice plate flow transducers, and magnetic flowmeters. This article will briefly discuss the technology and features of each of these types.

A turbine flow meter,

consists of a tube that contains supports to hold a multi-bladed metal turbine in the center. The turbine is designed to have close clearance to the walls of the tubing such that nearly all of the water is made to flow through the turbine blades as it travels through the pipe. The turbine is supported on finely finished bearings so that the turbine will spin freely even under very low flows. As the turbine spins, a magnetic pickup located outside of the flowmeter housing is used to sense the tips of the turbine blade spinning past the pickup. An amplifier/transmitter is then used to amplify the pulses and either transmit them directly or convert the pulse frequency into an analog signal that is then sent to a programmable controller for further use elsewhere in the system. One advantage of a turbine flowmeter is that the electronics are separated from the fluid path. The magnetic pickup is the only electronic component, and it is installed outside of the turbine housing, reading the presence of the turbine blade tips through the wall of the sensor body. In clean water applications, this can be advantageous because the magnetic pickup can be replaced if needed without removing the turbine from service. However, the turbine itself covers most of the pipe area and creates back-pressure in the system, requiring increased pumping energy to move a given amount of water. In Industrial Water Treatment or Filtration Treatment,  turbines can also easily become fouled or jammed if they are used to measure water or other fluids with entrained solids, algae or bacteria cultures which cause significant accumulation, or corrosive chemical components that can degrade the turbine bearings.

Ph Probes and Periodic Re-Calibration

Posted by Matthew C. Mossman P.E. on Aug 25, 2021 1:00:00 PM

In many water treatment and chemical processes,

it is a requirement to keep track of the pH of the water or product stream. In DeLoach Industries equipment such as degasification systems, or odor control scrubbers, pH measurement is critical to control the chemical reactions happening within the treatment system. PH is an indication of the acidic vs alkaline nature of a fluid. An acidic fluid will have a greater concentration of H+ hydrogen ions, while an alkaline fluid will have a greater concentration of OH- hydroxide ions. This electrochemical nature is used in the construction, reading, and maintenance of electronic pH probes.

PH probes are generally glass,

and will contain a reference element, and a sensing element. When the pH probe is immersed in the fluid to be measured, the electrical potential difference between the sensing element and the reference element is amplified by electronics, and the resulting voltage is used in a calculation to determine pH from differential electron potential. As a pH probe remains in service, ion exchange will slowly change the electrical potential of the sensing element, the reference element, or both. This happens because the hydrogen ions are small enough to travel through the glass sensor body and cause reference potential shift over time. This is a normal behavior for all pH probes and is the reason why pH probes must be periodically calibrated.

Water Degasification in Pisciculture

Posted by Anthony DeLoach, President on Feb 11, 2020 9:36:29 AM

The need to remove harmful elements from water such as Hydrogen Sulfide and Carbon Dioxide

from water in the pisciculture and aquaculture market is extremely important. In order to achieve maximum results, the industry utilizes a treatment technology called “Degasificationand controls the pH precisely to maximize results. When utilizing equipment such as the DeLoach Industries degasification systems the hydrogen sulfide and carbon dioxide levels can be removed to 99.999% ug/l.

pH control with water degasification in water treatment is very important for the aquaculture and the pisciculture market. In addition, there are a host of other organic and inorganic elements found in water both naturally occurring and manmade that require removal during some part of the water treatment process and pH plays a significant role on the effectiveness of the treatment process.

Every application of degasification depends on pH adjustment to maximize results. As an example, the treatment of water may require the removal of hydrogen sulfide (H2S) to protect the species during the growth period. Hydrogen sulfide can be removed either as a “free” gas or requires the conversion of sulfides into (H2S) as a gas they you will quite often also see the need to adjust pH of the water chemistry to maximize both the removal and the conversion to increase the efficiency of the equipment being utilized to remove the hydrogen sulfide such as a degasification tower or commonly called a degasifier.

Relationship of Water Degasification and Decarbonation and pH

Posted by Anthony DeLoach, President on Feb 3, 2020 1:01:00 PM

The need for pH control with water degasification and decarbonation in water treatment includes almost every industry and includes;

The need for pH control with water degasification and decarbonation in water treatment includes almost every industry and includes; Aquaculture, food and beverage, industrial, municipal, and even pisciculture.  In some water treatment applications, harmful gases such as Hydrogen Sulfide (H2S) are removed, while in other applications, Carbon Dioxide (CO2) or a combination of both. In addition, there's a host of other organic and inorganic elements found in water, both naturally occurring and manmade, that require removal during some part of the water treatment process.  

In almost every application of degasification or decarbonation, you will hear or see the term pH used either by need or by the result.  If, as an example, the water treatment application requires the removal of Hydrogen Sulfide (H2S) to be removed either as “free” gas or requires the conversion of Sulfides into (H2S) gas. You will often also see the need to adjust the pH of the water chemistry to maximize both the removal and the conversion to increase the efficiency of the equipment being utilized to remove the hydrogen sulfide, such as a degasification tower or commonly called a degasifier.

So, what is pH?

Water pH is a term used to describe whether or not the water is “acidic” or “basic.”  pH ranges in water can be from 0-14.  0 is the most acidic, and 14 is at the far end and is the most basic, leaving “7” as the neutral state.  A pH of 7 is neither acidic nor basic. So, what causes pH to be acidic?  In nature, the most common cause of a low acidic pH in water is Carbon Dioxide (CO2) which occurs naturally when photosynthesis, decomposition, or respiration occurs in nature.  The increase in CO2 causes an increase in ions, producing a lower pH in a simplified explanation.

How does pH play such a significant role in degasification and decarbonation? 

As mentioned above in the example of the removal of certain harmful elements such as sulfides, sulfates, and free H2S hydrogen sulfide gases, to maximize the removal from water utilizing a degasification tower, it is essential to maintain as close to a pH of 5 as possible.  When the pH rises above 5, the ability to convert and strip the free H2S gas from the water diminishes.  When a degasification tower operates within this specific range and if it has been designed with the higher efficient distribution systems such as the ones utilized by DeLoach Industries, removal efficiencies of 99.999%- 100% can be achieved.   If the pH rises to seven or above, the removal process becomes much more complex, and typically, you will have much lower results.  The pH adjustment during the water treatment process is typically accomplished by adding commercially available acid, such as “sulphuric acid,” one of the most common in the municipal and food and beverage industry.
