Pourquoi l'analyse de la qualité de l'eau potable est-elle cruciale ?

14 août 2024 ZL

Nowadays, RO home filters have become essential in many households. This is primarily because people are increasingly concerned about the safety and quality of their drinking water. It’s often difficult to determine whether the water we consume is safe, making these filters a vital part of ensuring health and well-being.

What exactly is the purpose of a drinking water tester?

1. Tap Water Safety

Potential Contaminants: Even treated tap water can contain harmful contaminants like chlorine, lead, or bacteria.
Regular Testing: Helps ensure your water remains safe, especially if your area experiences water quality fluctuations.

2. Hiking and Camping

Natural Water Sources: Streams, lakes, or rivers may appear clean but could be contaminated with pathogens.
Portable Testing: Ensures you avoid waterborne illnesses by verifying the safety of water before drinking.

3. Water for Pets

Pet Health: Just like humans, pets are vulnerable to water contaminants, and testing ensures their water is safe.
Outdoor Adventures: When hiking or camping with pets, testing water before allowing them to drink is essential.

4. RO Filter Maintenance

Filter Efficiency: RO filters degrade over time, reducing their effectiveness.
Testing Indicators: Regular water testing can indicate when it’s time to replace your filter to maintain optimal water quality.

5. Overall Health Assurance

Peace of Mind: Regular testing ensures you and your loved ones are drinking safe, contaminant-free water, protecting your health.

Let's take a look at what parameters we normally use to determine if drinking water is safe！

1. Total Organic Carbon (TOC):

What It Means: Measures the amount of carbon found in organic compounds in water.
Why It Matters: High TOC can indicate the presence of bacteria, viruses, microplastics, or decaying plant matter. For instance, if your tap water has a high TOC level, it could mean that there’s a buildup of organic contaminants, potentially leading to unpleasant odors, tastes, or even health risks.

2. Chemical Oxygen Demand (COD):

What It Means: Indicates the amount of oxygen required to break down organic matter in water.
Why It Matters: High COD levels could indicate pollution from industrial waste, untreated sewage, or agricultural runoff. For example, if you’re testing water from a nearby stream while camping and find a high COD, it could mean the water is contaminated with harmful chemicals and is unsafe to drink.

3. Total Dissolved Solids (TDS):

What It Means: Measures the concentration of dissolved substances like minerals, salts, and metals in water.
Why It Matters: A high TDS reading might mean your water contains high levels of salts, which could be due to natural mineral content or pollution. For instance, if your tap water has a high TDS level, it might taste salty or metallic, indicating potential issues with your local water supply.

4. UV Absorbance (UV275):

What It Means: Reflects the presence of organic substances by measuring how much UV light is absorbed at 275 nm.
Why It Matters: High UV absorbance can indicate the presence of organic pollutants like pesticides, herbicides, or even pharmaceuticals. For example, if your RO filter isn’t working properly and UV275 levels are high, it might be time to replace the filter to ensure your water is safe to drink.

5. Electrical Conductivity (EC):

What It Means: Measures the water's ability to conduct electricity, which is directly related to the concentration of dissolved salts.
Why It Matters: High EC levels could indicate the presence of dissolved salts or heavy metals. For instance, if you’re testing water in a remote area while hiking and find a high EC, it could suggest the water has picked up minerals from the soil, making it unsafe to drink without purification.

6. Temperature:

What It Means: Simply the temperature of the water being tested.
Why It Matters: While temperature itself isn’t directly harmful, it can affect how contaminants interact with the water. For example, higher temperatures can increase the solubility of certain chemicals, potentially making them more harmful.

These parameters help users assess whether their water is safe to drink, identify potential contaminants, and make informed decisions about water treatment or filtration.
