Common Contaminants and How Water Purification Systems Remove Them

Access to clean drinking water is a significant concern due to the presence of various contaminants that can pose health risks.

Understanding these contaminants and how a water purification system works to remove them is necessary for promoting the safety of our drinking water.

Here are the common types of contaminants found in drinking water and the mechanisms through which purification systems mitigate these risks:

Sediment

Sediment, encompassing a range of particles such as sand, dirt, and rust, frequently contaminates water sources, leading to issues with clarity and quality.

These particles can originate from natural processes like soil erosion or human activities, including construction and plumbing corrosion.

A water purification system targets these contaminants through a process where the water is passed through layers of filtration media. This method traps the sediment, preventing it from flowing through the rest of the system and reaching household taps.

Chlorine

Municipal water treatment facilities commonly use chlorine to eliminate harmful pathogens in drinking water. While effective in making water safe for consumption, chlorine can leave an undesirable taste and odor.

Water purification systems, specifically those utilizing activated carbon filters, can efficiently reduce chlorine levels. The activated carbon adsorbs the chlorine molecules, removing them from the water as it passes through the filter.

Reverse osmosis systems often include activated carbon filters in their multi-stage purification process. It provides an additional layer of removal for chlorine and other contaminants.

Heavy Metals

Heavy metals, including lead, arsenic, and mercury, are dangerous contaminants in drinking water, posing severe health risks even at low concentrations. These contaminants often enter water supplies through industrial runoff, aging infrastructure, or natural geological formations.

Electrocoagulation can effectively remove heavy metal ions from wastewater, leveraging electrical currents to treat contaminated water. Adsorption techniques using materials such as synthetic polymers, clay, and zeolites can help capture and remove heavy metals.

Microorganisms

Microorganisms, including bacteria, viruses, and protozoans, are prevalent contaminants in water. One effective method of purification is the use of ultraviolet (UV) light treatment. It disrupts the DNA of microorganisms, rendering them incapable of reproduction and causing harm.

Another purification approach is using reverse osmosis (RO) systems. It employs a semi-permeable membrane to block the passage of contaminants, including microorganisms, ensuring only clean water passes through.

Microfiltration (MF) techniques utilize physical barriers to remove particles and pathogens from water. These purification methods can provide multiple layers of defense against microorganisms, reducing the risk of waterborne diseases.

Pesticides and Chemicals

Pesticides and chemicals enter waterways through runoff from farms, lawns, and industrial sites, leading to widespread pollution. Water purification systems employ activated carbon filtration to combat these pollutants effectively.

This method relies on the adsorption properties of activated carbon, which binds pesticide and chemical molecules, removing them from water. Reverse osmosis systems integrate a semi-permeable membrane that further filters out these contaminants at a molecular level.

Together, these technologies can offer a robust solution for reducing the presence of pesticides and chemicals in drinking water, safeguarding public health.

Pharmaceuticals

Pharmaceuticals, including a wide range of drugs, from pain relievers to antibiotics. These substances enter aquatic environments through various pathways, primarily via wastewater treatment plants that are not fully equipped to remove such complex molecules.

Pharmaceuticals in water pose risks to aquatic life, affecting their growth, reproduction, and behavior and potentially impacting human health. Techniques such as advanced oxidation processes break down pharmaceutical compounds into less harmful substances.
