Need for Water Purifiers
For more than 2 million years, humans are struggling in search of pure water and nutritious food. Pure drinking water is one of the basic need for humans to survive and live a healthy life. The water which was considered good quality was found contaminated with chemicals and bacteria. Therefore, with the increasing demand of potable water, such water purifiers have come into existence.
Causes of water pollution
Some of the pollutants which are identified in water are sodium, lead, benzene, cyanide, zinc, magnesium, calcium, insecticides, herbicides, detergents, nitrates, dioxin, chlorine, industrial wastes, algae, bacteria, radioactive substances. Every year new chemicals are created which pollute water even more. These pollutants are tasteless, odourless and invisible that is why they remain untreated for a long time.
Types of water pollution and their solution
| No. | Type of water Pollutant | Reason | Solution |
| 1 | Undissolved Impurities | Mix of various undissolved impurities in both surface and ground water | Filtration |
| 2 | Water pollution by chemicals in Natural Organic Matter or oxygen depletion | Natural organic matter (NOM) found in all surface, ground, and soil waters add chemicals in water | Most of the Natural Organic Matter are removed by coagulation, although, the hydrophobic fraction and high molar mass compounds of NOM are removed more efficiently |
| 3 | Water pollution with microbial | Bacterial cells and viruses constitute microbial water pollution | Antimicrobial nanomaterials used for water disinfection and microbial control |
| 4 | Water Pollution by Chemicals | Organic and inorganic chemicals | Use of Carbon Nano Tubes as adsorbent media to concentrate and remove pathogens, NOM, and cyanobacterial toxins from water systems. |
| 5 | Dissolved Calcium ion in water | Dissolve metals in water | Nanophotonics |
| 6 | Desalination of seawater | Dissolved NaCl in seawater | Treatment through Nanomembrane |
| 7 | Treatment of sewerage Water | Inorganic and Organic pollutants | Treatment through Chlorine Dioxide |
An ideal water purifier removes both dissolved and undissolved impurities by removing all contamination from the water. It uses a physical barrier, a chemical process, an optical process or a biological process to convert impure water into 100% pure water.
Do you know how water purifier work?

Total dissolved solids (TDS) in Drinking-water
Total Dissolved Solids (TDS): It is defined as inorganic salts and organic matter present in water that can pass through 2-micron filter. In simple words, TDS is the cations and anions in the water. The main constituent which decides TDS of water includes, carbonate, bicarbonate, chlorine, fluoride, sulfate, phosphate, nitrate, calcium, sodium and potassium. In general, any ion which is present in the water will contribute to the total. The dissolved solids affects the taste of water.
Taste of water with different TDS concentration
| TDS Level mg/L | Rating |
| Less than 300 | Excellent |
| 300 – 600 | Good |
| 600 – 900 | Fair |
| 900 – 1200 | Poor |
| Above 1200 | Unacceptable |
What is TDS Meter?
A TDS meter is an electronic device that measures Total Dissolved Solids (TDS) of a solution.
TDS Meter
How to measure TDS of water at home?
- To start, open the protective cap of the meter and turn the switch on.
- The mark on the meter indicates the portion of the meter, to submerge in sample water.
- Dip the meter into the sample water until that mark.
- Eliminate if there is an air bubble by gently moving the meter.
- The meter reading will vary. Wait for 10 to 15 seconds for the result to balance out.
- When the reading gets settled, press the hold button and take the meter out from the water.
- Presently observe the outcome.
