Water is life, but using dirty water can cause dangerous diseases in your body. Untreated water can contain harmful microorganisms and pollutants that cause water based diseases such as cholera, typhoid, and dysentery. Therefore, you need a good quality water purifier to guarantee that you are drinking safe water. This way, you will never risk yourself to infections and chronic diseases. 

This blog will help us understand how water purifiers work and how they play a significant role in preventing disease-causing agents from entering our bodies through water. 

Most Common Contaminants in Drinking Water

Types Of Water Disease

Untreated water can give birth to hazardous contaminants that can cause serious health issues. These are as follows: 

  • Bacteria – Pathogens such as E. coli and Salmonella flourish in contaminated water and can trigger serious intestinal infections and water based diseases. These can result in diarrhea, vomiting, and abdominal pain.
  • Viruses – Waterborne viruses, including Hepatitis A and rotavirus, can be introduced through drinking water, leading to liver inflammation, digestive disorders, and long-lasting illness.
  • Parasites – Giardia and Cryptosporidium are tiny parasites that can be present in untreated water and can cause chronic gastrointestinal issues like ongoing diarrhea and stomach cramps.
  • Heavy metals — These are the toxic elements such as lead, arsenic, and mercury, which leach into water sources from industrial waste, corroded pipelines, and agricultural runoff. Long-term exposure can lead to dirty water based diseases such as neurological impairment, developmental problems in children, and kidney failure.
  • Hormonal disruptors – Chemicals, such as pesticides, herbicides, and industrial chemicals, can leach into groundwater from the earth, and they can cause hormonal imbalances, help with cancer development, and cause reproductive issues.

How Water Purifiers Work

Ro Working
 

Water purifiers employ advanced filtration technologies to remove impurities and microorganisms to ensure safe drinking water. Thus, you can prevent water based diseases much more easily. The three most common ways are:

  • Reverse Osmosis (RO)It employs a semi-permeable membrane to eliminate dissolved salts, heavy metals (lead and arsenic), chemical pollutants, and some pathogenic microbes. In fact, the areas with high Total Dissolved Solids (TDS) in water need RO purifiers.
  • Ultraviolet (UV) Purification – This applies high-intensity Ultraviolet rays to kill bacteria, viruses, and other microorganisms by disrupting their DNA and preventing reproduction. This method eliminates microbial contamination, causing water based diseases without changing its taste or essential minerals.
  • Ultrafiltration (UF) – It uses a hollow fiber membrane that filters out bacteria, cysts, and sediments. UF is different from RO in that it does not need electricity to operate and that, unlike RO, it does not remove essential minerals from water; this makes UF perfect for areas with low microbial content but high particulate material.

A few of the best and most advanced purifiers include RO+UV+UF mechanism for multi-stage filtration solutions to offer comprehensive protection against all possible water based diseases. 

Health Risks of Drinking Contaminated Water

Untreated water can cause various complications, which you may find hard to deal with. Therefore, you must keep a check that you do not develop water-based diseases due to contamination, such as: 

  • Gastrointestinal Infections– Contaminated water often makes people sick because it contains harmful bacteria and parasites that lead to diarrhea, nausea, and vomiting, resulting in digestive distress and dehydration.
  • Liver Damage – Water-borne viruses like Hepatitis A can be contracted from drinking contaminated water, leading to long-term liver complications and serious infections.
  • Chronic Dehydration – Consuming contaminated water constantly can cause repeated infections in the body and loss of body fluids, leading to acute dehydration.
  • Compromised Immune System – Frequent bouts of sickness from drinking contaminated water can leave your body vulnerable to infections, diminishing immunity in the long run.
  • Higher Chances Of Disastrous Diseases – Water based diseases like cholera, typhoid, and hepatitis A can cause major issues if untreated, hospitalization and even death.

Choosing the Right Water Purifier

The best purifier for you will depend on your water source and its contaminants. Consider the following:

  • High TDS WaterRemoval of dissolved solids, heavy metals, and chemical pollutants that hamper the taste and safety of drinking water can require an RO system.
  • Microbial contamination – Bacteria and viruses are effectively neutralized, making UV or UF purifiers ideal for areas where microbial contamination is a cause for concern.
  • RO+UV+UF: Mixed contamination – The RO+UV+UF process offers complete purification, perfect for areas where high TDS and microbe contamination coexist.

One way to ensure their quality is to buy them from a reputable and reliable source, such as Aqua Drink.

Importance of Regular Maintenance

A well-maintained water purifier works well if you want safe water to drink. Regular servicing includes:

  • Changing the purification filters from time to time
  • Checking and fixing components to avoid malfunctions and ensure smooth running.
  • Preventing biofilm formations and bacterial formations in storage tanks.
  • Testing water pressure and flow rate to maintain efficient performance.
  • Choosing annual maintenance contracts for hassle-free maintenance and timely service.

These additions ensure comprehensive coverage of the topics while maintaining clarity and user engagement. 

Buy the Right Water Purifier 

A water purifier acts as a safeguard against water-related diseases. By removing hazardous contaminants, purifiers ensure you and your family drink safe, clean water daily. Properly maintaining and selecting the appropriate water purification technology allows you to mitigate the health risks of water contamination
