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.

A manufacturing facility cannot ignore the importance of odor control.
The smell of chemicals, vapors, and fumes can spread quickly in a small area. They cause discomfort to workers and pose health risks to them. In addition, 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 with odor issues. 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.
Anyone working in an industrial environment, 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 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, choosing the right scrubber type that suits your industry’s requirements is crucial. 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.

The water treatment industry has developed and evolved over the years to continue to find new ways to produce degassed water,
with many advances in both the technological methods of treatment as well as the refinement of the existing methods. The evolution of water treatment has been driven by the need for increased demand and over safety standards.
All human cultures on our planet share a
single commonality and
that is the dependency on water to survive.
Many existing technologies such as “degasification” have evolved with higher efficiency to meet the demand changes and provide safety to consumers and to systems. Degasification refers to the removal of dissolved gases from liquids and the science to degasify water is based upon the “Henry’s Law” or to be exact the “proportionality factor is called the Henry’s law constant” and was developed by William Henry in the early 19th century.
Henry’s Law states that the amount of dissolved gas is proportional to its partial pressure in the gas. The most effective method to perform degasification is with the packed vertical tower called a degasifier or decarbonator. When water enters at the top of the tower it gravity feeds downward across a media bed. The media bed acts to reshape the water over and over again exposing any dissolved gas molecules to the surface of the water droplet. At the same time that the water is traveling down the interior of the tower an air flow is introduced in a cross current method either by force or by induction that passes over the water droplets and “strips” the gas molecules out of the water. The gases that are stripped then leave the tower through the exhaust at the top of the tower. This is the “basics of water degasification”.

When selecting a water treatment process it is important to consider all of the variables for the application before deciding on materials to be considered and the method of construction. In the water industry professionals are governed by certain requirements and standards and you will commonly here the terms “NSF certification”. FDA Chapter 21 and NSF/ANSI 61 standard also applies.

Water treatment towers and storage tanks are high places that require special precautions when entering. While the majority of people who enter these locations for work can be trusted, there are some hazards that make it more important than usual to follow safety procedures.
These locations can get very hot and humid, and can also be filled with harmful chemicals and microorganisms that can cause serious health issues if inhaled or absorbed through the skin. Therefore, the general standard for workplace safety is much higher when entering locations like these.
Make sure you have read and understood the following information about safety when entering a water treatment plant. It will help you understand how to stay safe and protect yourself from harm when entering a water treatment plant. normal installation, maintenance, or even emergency repairs, it is often required to enter into a water treatment tower (degasifier, air stripper, decarbonator, or clear well/ storage tank). When this occurs, full safety protocols should be followed at all times, in accordance with OSHA regulations. A tower or tank B classification is a "Confined Space" location. For more information visit the OSHA combined space regulations page.
In addition, there are other safety risks that an operator or technician can be exposed to while inside these types of closed locations. The risk can come from fumes of hydrogen sulfide (H2S), chlorine from an injection line, or a lack of oxygen O2. A proper confined space permit should be prepared and only technicians with proper training and certifications should enter into these types of confined spaces.
