If you’ve been following the news, you know a growing problem with PFAS (per and poly-fluoroalkyl substances).
These man-made chemicals are found in everything from clothing to food packaging. While they are inexpensive and stable in products, some tend to break down into other substances, such as PFAS-methyl tetrahydrofuran. PFASs have been discovered in drinking water nationwide, including in parts of the country with very high water tables. As a result, it’s essential 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 essential 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 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 specific contaminants. Use these tests to determine whether your water is safe to drink. If your water contains contaminants, you need to remove them from your water source. This can be done by digging a more bottomless 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.

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.

In water treatment, it is often required to remove small particulate matter from the raw water. One of the most cost-effective ways to accomplish this is with a pressure filter. Sometimes referred to as “sand filters,” a pressure filter consists of a rigid filter vessel capable of withstanding internal pressure, combined with pipework to distribute and collect water and one or multiple types of filter media. Pressure filters are commonly used in municipal water systems, industrial facilities, residential well water systems, and swimming pools. Typical pressure filter construction is shown below:
At the top of the filter vessel, a distributor is used to break up and distribute the water flow so that there are no concentrated flow jets that stir up the media bed. Inflow distributors are usually oriented to direct flow at the top of the vessel to disperse the flow further. Below the distributor is the primary filter bed. The filter bed contains fine-grained media, most often sand, including crushed anthracite coal, activated charcoal, garnet, or other granular bulk products. The media bed is the thickest layer in the filter vessel and is the region that does the actual filtering of the water or other fluid. Below the media bed will be one or more support layers. These will usually be larger-sized gravel that is chosen to support the filter bed while allowing high flow through the support layer and into the outflow header. The outflow header can take several forms but is often composed of a large central pipe with multiple smaller pipes or “laterals” attached. The laterals are slotted or perforated. This allows the pressurized water to flow into the laterals and out through the outflow header into the downstream components of the water treatment system.

Ammonia (AM) is a common water pollutant that significantly impacts the water process industry. It is not just polluting water bodies but also aqua wells and humidifiers. Generally, AM is produced from human sweat and urine and created from synthetic ammonia in industrial process systems.
Ammonia has three types of amines – primary, secondary, and tertiary – all are toxic for humans and aquatic life.
- Primary Amine has two carbon and one nitrogen atom also called methylamine or CHNH2.
- Secondary Amine has two nitrogen atoms with no carbon atom between them, also called Dimethylamine or CH2(NH)CH3.
- Tertiary Amine has three nitrogen atoms with no carbon atoms between them; thus, it’s called Trimethylamine or CH3C(NH)CH3.
In natural conditions, primary Amide bacteria produce Amide under high-temperature conditions. In an aqueous solution and soil environments with high pH levels (>6).
Primary amide can form by the dehydrogenation of nitriles, such as acetonitrile, which are further oxidized to form acetic acid.
Primary amide form by alkaline hydrolysis of nitro compounds such as 2-nitrophenol.
Process systems often need to recognize when the Degasification or Decarbonation system is failing or underperforming.

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.
