Even water that looks clear may contain dirt, minerals, chemicals and other impurities that affect its smell ortaste. It may even contain microbes that could endanger your health. Pollutants can enter water at anypoint of water cycle, such as lakes, rivers, and ponds.
Causes of contamination include:
Agriculture Runoff
Water used in farming containsfertilisers, pesticides / herbicidesand other pollutants
Storm Water Runoff
Rainwater flowing through drainsand ditches picks up all kinds ofcontaminants
Leaking Landfills
Various contaminants and toxicchemicals from garbage canleach into the groundwater
Industrial Discharge
Factory waste is oftendischarged directly intowater bodies
Personal Care /Household Products
Detergents, medicines, makeupand other contaminants go downthe drain and into water sources
Rusting Pipes
Water picks up rust andother sediments from thecorroded pipes
Total dissolved solids (TDS)
| What is it? | Caused by: | Measured in: |
|---|---|---|
Contaminants smaller than 2 microns. Moderate to high TDS changes water’s taste and odour and poses health hazards. |
Weathering and erosion, as well as human activities, which cause materials to be dissolved in water. |
Parts per million (ppm) (equivalent to milligram per litre of liquid water). |
National standard for drinking water: 1000mg / l
Turbidity (water clarity)
| What is it? | Caused by: | Measured in: |
|---|---|---|
Suspended particles in water. The higher the turbidity, the more particles there are. |
Soil erosion, high levels of nutrients, various waste products and pollutants, bottom-feeding organisms which stir up sediment in the water. |
Nephelometric Turbidity Unit (NTU). The lower the NTU, the clearer the water is. |
National standard for drinking water: less than 5 NTU
Colour of water
| What is it? | Caused by: | Measured in: |
|---|---|---|
The more colour water has, the less transparent it is. |
Dissolved substances in water. |
True Colour Units (TCU). Lower TCU means there are fewer dissolved substances in water, making the water more transparent. |
National standard for drinking water: 15 TCU
pH-level of water
| What is it? | Caused by: | Measured in: |
|---|---|---|
“Potential hydrogen” is a measurement of a substance‘s hydrogen level. |
Water pH varies depending on weather, human activity, and natural processes. |
A scale of 0 to 14. Water can be acidic (pH 0 to 7), neutral (pH 7) or alkaline (pH 7 to 14). |
National standard for drinking water: 6.5-8.5 pH
Total iron
| What is it? | Caused by: | Measured in: |
|---|---|---|
Total iron includes all of the different forms of iron that exists in water, such as ferrous or ferric iron, complexed iron, or iron oxides (rust). |
Iron exists in natural water sources but may also come from industrial wastes, iron refineries, or corrosion of metals. |
Milligram per litre of liquid water. |
National standard for drinking water: less than 0.3 mg / l
Hardness of water
| What is it? | Caused by: | Measured in: |
|---|---|---|
Water with a high mineral content that causes calcification and lime scaling. |
Water seeping through limestone and chalk which absorbs the minerals in them. |
Milligram per litre of liquid water. |
National standard for drinking water: less than 500 mg / l
Total coliform count
| What is it? | Caused by: | Measured in: |
|---|---|---|
Indicates the bacteria level in water. |
Found in digestive tracts of animals and humans. It is excreted in their wastes and absorbed into plants and soil. |
Total number of coliform bacteria. |
National standard for drinking water: 0 total coliform
Have you ever wondered how your Bacfree filter keeps your water safe, healthy and pure? Take a peek intowhat’s going on inside and see how our technology works to remove impurities, kill microbes and improveyour water.
UV Disinfection System
Zaps microbes and destroys them at the molecular level.See how it works in Bacfree’s UV Disinfection System, Horeca Series For Food And Beverageand Water Treatment Solutions.
Premium Filter Elements
The core of our systems, shielding you from harmful impurities.See how it works in Bacfree’s BS Series Direct Drinking Tap Filters.
Reverse Osmosis System
Harnessing the power of physics to purify your water.See how it works in Bacfree’s Watero and Water Treatment Solutions.
Advanced Ioniser System
Enhances water’s properties for extra health benefits.See how it works in Bacfree’s HealthSpring Advanced Ionizer System.
Multimedia Filtration
Multi-layered protection to block out all possible impurities.See how it works in Bacfree’s ER Series Outdoor Filters and IC Series Centralised Filtration System.
While different applications require different levels of water quality, what is most important is thereliability of the filtration system to deliver on the requirements. As the water filtration pioneer inMalaysia, Bacfree sets the standard in this area. Our filters have helped millions attain not justclean water, but Bacfree Clean Water. See the results for yourself.
