A water softener is a device that reduces the hardness of hard water by removing minerals such as calcium and magnesium. Softening water helps to reduce the buildup of scale in pipes, appliances, and fixtures. It also prevents otherwise damaging mineral deposits from occurring in hot water boilers and other equipment. Some systems are designed to remove iron or other metals from the water as well. Water softeners are available in a variety of sizes and can operate on either electricity or salt. They are typically installed at the point-of-entry (POE) to provide softened water for the entire home.

What Are Biological Contaminants?

Biological Contaminants

Biological contaminants are pollutants that originate from living organisms. Examples include

  1. Bacteria: Bacteria are single-celled organisms that can cause water contamination. They range in size from 0.2 to 10 microns and multiply quickly when given the right conditions. Examples of bacteria found in water include Legionella, E.coli, and Salmonella.
  2. Viruses: Viruses are even smaller than bacteria (ranging from 0.004 to 0.1 microns) and are capable of causing illnesses such as gastroenteritis, dysentery, and hepatitis A.
  3. Protozoa: Protozoa are larger than bacteria (ranging from 1 to 10 microns) and can cause waterborne diseases such as Giardiasis and Cryptosporidiosis.
  4. Fungi: Fungi are typically larger than bacteria and viruses (ranging from 1 to 30 microns) and can cause skin infections, allergic reactions, and respiratory problems.

These contaminants can be found in water sources such as rivers and lakes but can also appear due to a malfunctioning septic system or industrial waste release. It is important to note that boiling water does not necessarily remove these contaminants.

The type of contaminants found in a water supply depends on its specific source.

  • Drinking water may contain Biological Contaminants.
  • It may also contain heavy metals, biological toxins such as PCBs and dioxins, pesticides and herbicides from agricultural runoff, industrial solvents, and petroleum products.

Does Soft Water Systems Filter Biological(Contaminants)?

Unfortunately,  Soft Water Systems do not remove biological contaminants like bacteria, viruses, or protozoa.

It is important to have your water tested regularly by a certified lab to ensure it is free of harmful contaminants. By taking these necessary steps, you can ensure that your drinking water is safe and healthy for consumption.

Which Water Softener Is Better For Removing Biological Contaminants?

The type of water softener that is best for removing biological contaminants depends on the specific needs and preferences of each household. Generally speaking, reverse osmosis systems are highly effective in filtering out a wide range of contaminants, including bacteria, viruses, protozoa, and fungi.

No matter which type of water softener you choose, it is important to remember that they are not designed to remove all types of biological contaminants from drinking water. Thus, it is recommended to also install a carbon-based filtration system in order to ensure your drinking water is safe and healthy.

Does A Water Softener Remove Bacteria?

NO.water softener alone is insufficient to remove all harmful contaminants from your drinking water.

  • Pathogenic Bacteria: The best method for removing pathogens from drinking water is to install a combination of filtration systems. This includes a carbon filter to trap organic pollutants, an ultraviolet (UV) filter to kill microorganisms, and optionally, a reverse osmosis (RO) system to reduce fluoride levels. While softeners are not designed to remove bacteria, they can still help in reducing the presence of bacteria and other microorganisms. This is because softeners remove calcium and magnesium, which are essential nutrients for bacteria to survive. As a result, softening water can reduce the amount of pathogens present in your drinking water supply.
  • Non-Pathogenic Bacteria: Non-pathogenic bacteria, such as those naturally present in water supplies, are not harmful to humans and animals. Water softeners are not designed to remove non-pathogenic bacteria from drinking water. However, adding a sediment filter before the softener can help reduce the presence of these bacteria in your supply. This will make your drinking water safer and better tasting.

By using a combination of filtration systems, you can ensure that your family has access to safe drinking water at all times. This will help to protect their health and prevent any potential illnesses caused by contaminated water.


Does Ion Exchange Filtration Remove Bacteria From Water?

Ion exchange filtration can remove some bacteria from water, but it is not usually effective at removing all types of biological contaminants. To thoroughly remove bacteria and other biological contaminants from your drinking water, you will need to install a carbon-based filtration system in addition to an ion exchange filter.

Are Ultraviolet (Uv) Filters Effective In Removing Biological Contaminants?

Ultraviolet (UV) filtration is highly effective in killing most microorganisms present in water, including bacteria, viruses, protozoa and fungi. However, it does not remove other types of particles or pollutants from the water, so other filtration systems may be necessary to ensure your drinking water is safe and healthy.

Do Water Softeners Remove Heavy Metals From Drinking Water?

No, water softeners are not designed to remove heavy metals from drinking water.

Does A Water Softener Help To Remove Chlorine From Drinking Water?
