FAQ in Water quality and Water purifiers

1) What is TDS?

Dissolved solids” refer to any minerals, salts, metals, cations or anions dissolved in water. Total dissolved solids (TDS) comprise inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates) and some small amounts of organic matter that are dissolved in water.

2) What is the unit of TDS measurement?

Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm).

3) What is the recommended TDS level in Tap water?

The lower the level, the better. TDS levels exceeding 1,000 mg/l is a general indication that the water is undrinkable. The U.S. Environmental Protection Agency (EPA) suggests a limit of 500 mg/l, however. Water registering a TDS level of < 200 mg/l can be considered pretty good and can be used as feed water source for most of the popular water filtration technologies available in market.

However most RO purifier manufacturers recommend installation of RO technology only if the Tap water TDS exceeds 500 ppm.

4) What is Hard water?

Water Hardness is most commonly expressed as milligrams of calcium carbonate equivalent per liter. Water containing calcium carbonate at concentrations below 60 mg/l is generally considered as soft; 60–120 mg/l, moderately hard; 120–180 mg/l, hard; and more than 180 mg/l, very hard

5) What is pH?

The pH value of a water source is a measure of its acidity or alkalinity. The pH level is a measurement of the activity of the hydrogen atom, because the hydrogen activity is a good representation of the acidity or alkalinity of the water. The pH scale, as shown below, ranges from 0 to 14, with 7.0 being neutral. Water with a low pH is said to be acidic, and water with a high pH is basic, or alkaline. Pure water would have a pH of 7.0, but water sources and precipitation tends to be slightly acidic, due to contaminants that are in the water.

6) How do water treatment facilities change the pH of water?

There are several methods that can increase the pH of water, before disinfection. The pH is commonly increased using sodium carbonate and sodium hydroxide, but a better way of dealing with low pH is to use calcium and magnesium carbonate, which not only will increase pH levels, but will also make the water less corrosive and both calcium and magnesium are of health benefits as opposed to sodium.

7) How does UV technology work in water purifiers

Ultraviolet water purification is a simple but effective process that destroys around 99.99% of the harmful organisms in water. There is a tiny mercury lamp inside the purifier that produces short wave UV radiations. The DNA of the pathogenic organisms is modified in such a way that they cannot multiply and cannot cause diseases. UV treatment does not alter water chemically; nothing is being added except energy. The sterilized microorganisms are not removed from the water. These rays have the ability to inactivate 99.9% of the microorganisms.

8) How does Reverse Osmosis work?

Reverse Osmosis works by using a high pressure pump to increase the pressure on the salt side of the RO and force the water across the semi-permeable RO membrane, leaving almost all (around 95% to 99%) of dissolved salts behind in the reject stream.

The desalinated water that is demineralized or deionized, is called permeate (or product) water. The water stream that carries the concentrated contaminants that did not pass through the RO membrane is called the reject (or concentrate) stream.

9) How does Nano positive filter work?

As a electropositive charged porous water treatment filter, This is a special advanced filter that maximizes the removal efficiency of the filter by adding an electrochemical mechanism (electrostatic force) without depending on the physical mechanism (pore size) of the filter

Electrostatic force is applied to selectively adsorb and remove various bacteria, fine particles, heavy metals, viruses to provide beneficial water

This filter can be confirmed that it is coated with positively charged polymer resin on the surface of the fiber material filter media (PET), and it has an excellent effect to remove micro colloid material with anion in water and microorganisms such as viruses and bacteria

10) Why should we consider an alternate drinking water source compared to plastic bottled water?

The primary risk associated with drinking bottled water is the fact that you can be exposed to harmful toxins from the plastic. … BPA and other plastic toxins can then make their way into your bloodstream, which can cause a host of problems including various cancers as well as liver and kidney damage.

11) Why should we avoid exposing plastic bottled water in extreme sunlight?

“The hotter it gets, the more the stuff in plastic can move into drinking water.” Drinking from a single water bottle left in the hot sun won’t hurt you, but experts say consumers should avoid persistent exposure to plastic containers left in extreme heat

12) What Is Water Pollution?

Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.

13) What are the bad effects of Plastic pollution?

Because plastic is such a persistent material, the ecological, economic and eco-toxicological effects of plastic pollution are all long-term. These include: Physical impact on marine life: entanglement, ingestion, starvation. Chemical impact: the build up of persistent organic pollutants like PCBs and DDT.

14) Why is water purifier / water filter becoming a popular choice for drinking water at home and workplace?

  • Removes Chlorine from Tap water
  • Better for the environment
  • Reduces Tap water Odor
  • Makes your food Taste better
  • Saves Money from Bottled water
  • Removes heavy metals from water
  • Offers Convenience
  • Reduces the risk of re contamination of water
  • Makes better Coffee and Tea
  • Purity you can see in front of your eyes

15) What is infused water?

Any combination of fruits, vegetables and herbs immersed in water is what makes infused water. Infused water is also referred to as fruit infused water, fruit water, fruit flavored water and detox water.
