In the 21st century, all people’s are very concern about drinking water. Drinking package water tendency increased globally day by day and also uses home water filtration system. The home filtration water is good for your health if you buy the right purification technology purifier based on your Feedwater quality. You always need to select a water purifier based on Indian Drinking Water Standards Parameter Limits.

As of now, thousands of water purifier available in the market with different filtration technology used. The basic filtration process is the same; only change the number of stages based on feed water quality & final water requirement.

Maximum peoples are don’t know how to select the right water purifier. If you think a costly RO water purifier means you get healthy water, this is not correct. Water purifier always needs to selection based on feed water quality. If you still have some dought, read under below article.

Now we are discussing different stage of filtration using the water filtration company.

Drinking-Water Filtration Stages:

1. Sediment filtration:

Sediment filters remove suspended solids, also known as sediment, turbidity or particulate matter. A sediment filter acts like a mesh that catches unwanted dirt particles when water flows through your system.

2. UF (Ultrafiltration):

A micropore membrane filter removes particles according to the pore size. In contrast, an ultrafiltration (UF) membrane acts as a molecular sieve. It separates dissolved molecules based on size by passing a solution through an infinitely fine filter.

It can remove 80% – 90% microorganisms and suspended partial and can not remove TDS (total dissolved solids). It was perfect for drinking water use where the TDS under control limit.

3. RO (Reverse osmosis):

RO (Reverse osmosis) is the most economical method of removing 80% to 95% of all pollutants. The pore structure of the RO membrane is much tighter than that of the UF membrane.

It completely removes all microorganisms and removes suspended particles and solid 80 – 95% of the total dissolved. It was perfect for drinking water use where the total dissolved solids (TDS) is under the control limit.

4. ACF (Activate Carbon Filter):

It is a popular technique used to treat domestic drinking water filters with chlorine due to its aggressive odour and ability to purify water from the taste. It had a degrading odour and improved water testing.

5. UV (Ultraviolet):

Ultraviolet water purification is the most effective method of disinfecting bacteria from water. Ultraviolet (UV) rays pass with water kill harmful germs, attack their genetic core (DNA) and destroying microorganisms. It kills all kinds of microorganisms, bacteria and viruses.

This five stages use basically for home uses purpose. Now we see the India drinking water standards parameter limits.

India drinking water standards parameter limits:

Sl NoCharacteristicAcceptable limit
01pH6.5 – 8.5
02Turbidity (NTU), Max01
03TDS (Total Dissolve Solid) mg/l, Max500
04Calcium (as Ca), mg/l, Max75
05Chloride (as Cl), mg/l, Max250
06Copper (as Cu), mg/l, Max0.05
07Fluoride (as F) mg/l, Max1.0
08Iron (as Fe), mg/l, Max0.3
09 Magnesium (as Mg), mg/l, Max30
10Total alkalinity as calcium carbonate, mg/l, Max200
11Total hardness (as CaCO3), mg/l, Max200
12Zinc (as Zn), mg/l, Max5

This is India drinking water standards parameter limits based on the environment, but we don’t know our drinking water parameter meets the above limitations. All parameter analysis at home is complicated & expensive, but without analysis, you cannot know.


Based on our expertise in the water treatment industry, if you analyse only two-parameter, pH & TDS, you will get an average idea of your drinking water quality.

Drinking Water TDS limit:

TDS means “Total Dissolve solid” That is equivalent to all dissolve solid. If TDS is under control means, others all dissolve solid possibility under control. As per the standard limit, drinking water TDS should maintain under 500 mg/l.

Some example of Potable TDS meter available in the online shop. The cost of the portable TDS meter is around Rs. 200/- to 300/-.

pH for Drinking Water Standards:

pH is another vital parameter in water. pH can indicate the water is acidic or alkaline. The pH scale is 0 to 14. The 7 pH is neutral or balanced between acidic and alkaline. If water is below 7 pH, it’s “acidic.” If it’s higher than 7, it’s “alkaline.”

As per the standard limit, drinking water pH should maintain 6.5 to 8.5. Lower pH or higher pH can create several side effects in your body.

A portable pH meter is available on an online site at a comfortable price.
