Different Water Treatment Processes You Can Use To Remove Unwanted Chemicals

According to the United States Environmental Protection Agency there may be 80 types of contaminants that can be present in tap water that poses risk to human health. But the general categories are physical, chemical, biological and radiological.

Chemical contaminants are the major one that is found in water. These are elements or compounds that are natural or manmade. Examples are nitrogen, salts, pesticides, bleach, minerals, metals, toxins, bacteria’s, human or animal drugs.

However, mostly minerals like fluoride, calcium, magnesium, nitrate, arsenic and bacterial growths are common in water supplies. The Municipal Corporation assures that water is safe to drink but the major segment uses well water that may contain residues. Also, it cannot be denied that hard water supply is there across the country. Many Americans are still unaware of health hazards chemicals impose on health. Hence we have listed different water treatment processes that can be used to remove unwanted chemicals from drinking water.

Why my tap water contains chemicals?

There are two main reasons for chemicals in tap water. Firstly, a small number of chemicals like chlorine and fluoride are good for health. Chlorine helps to eradicate bacterial growth and get rid of sediments whereas fluoride maintains dental health. Secondly nitrate and arsenic are a naturally occurring substance in water. Many times they don’t impose any health issues as less amount of traces are present.

Chemicals and Health:

Chlorine is added to water supplies by the water board for cleaning purpose. It is the most scrutinized chemical when comes to health concerns. Consuming chlorine more than a specific level is linked to asthma, cancer and heart diseases. Similarly, fluoride causes brain and thyroid issues and also leads to behavioral problems.

There are many products that lead to health issues from which many are unacquainted. Like aluminum when present in excess amount raises water acidity which results in high absorption of cadmium, copper, lead and heavy chemicals drawn from pipes.

What to do once you have discovered chemicals in drinking water?

After discovering there are chemicals present in your water supplies it is difficult to know the type of chemicals. In this case, water testing is a good idea to be applied before any water treatments. This will let you know which chemical is hampering your health so that you can apply the best remedy.

Different Water Treatment Processes:

Why do I need a water filter? This question strikes on every mind. But as we have stated above that sediments, chemicals and impurities affect water quality. They taste and smell differently that indicates water issues. The water filtration system is the best way to eradicate chemical compounds and all contaminants from water. Here are four main types of water treatment systems that you can choose as per the problem and preferences:

RO system (Reverse Osmosis): Reverse Osmosis is the process of reduction of salts from water via semi-permeable membrane which rejects all types of sediments and chemicals from water. When water is forced through the membrane the dissolved minerals are repelled which causes only water molecules to pass through providing fresh and pure drinking water.

Ultraviolet (UV system): We know sunlight kills bacteria and microorganisms, right. The sun rays have a UV spectrum that is used in water filtration. However, the intensities are nil in comparison to sunlight.  It is also known as Germicidal Spectrum or Frequency. The frequency used in UV systems is 254nm (nanometer). The digital lamps with this frequency are said to be the highest amount of UV energies.

Filtration: A process where water passes through one or more filters for removal of taste, odor, chemical, turbidity, and color is known as filtration. The design can be either cartridge devices or loose media tank type. Actually, the process involves mechanical, neutralizing, absorption and oxidizing filters.

Distillation: The process where any liquid like water is heated, evaporated, cooled and condensed to a liquid state again to collect is known as distillation. In this process, contaminants are removed completely from the water. Distilled water has to pass through many evaporations and condensation cycles by eliminates salts and dissolved solids. To carry a small distillation process a lot of energy is required that is why it is not recommended.


Hope now you know the different methods to remove unwanted chemicals in water. Even if you have a municipal water supply at home it doesn’t mean that chemicals are not present in it. As mentioned here chlorine and fluoride are there as they are used to treat water contamination. There are various options available in the market choose the best filter system for your home according to the water quality.

Let us know which water treatment was functional for you? And what you think about the water filtration system?
