Questions & Answers on TDS
Best Water Purifier For You
Check out the best water purifiers based on your needs & water quality.
You can present a scrollable FAQ list. Here are 15 sample Q&A entries with suggested answers:
Q1) What is TDS exactly?
TDS (Total Dissolved Solids) is the combined concentration of dissolved inorganic salts and small organic substances in water, measured in mg/L or ppm.
Q2) Is TDS harmful?
Not inherently. Some dissolved minerals (like calcium, magnesium) are beneficial. But very high levels may affect taste, cause scaling, or indicate the presence of harmful contaminants.
Q3) What is a good TDS for drinking water in India?
Ideally, between 50–300 mg/L is considered good; BIS allows up to 500 mg/L as acceptable.
Q4) Does WHO set a strict TDS limit?
No. WHO does not define a health-based limit for TDS; rather, it mentions palatability and aesthetic considerations.
Q5) What happens if TDS is very low?
If water is too low in dissolved minerals (< 50 ppm), it may taste flat and lack beneficial minerals. Some systems may reintroduce minerals for taste and health.
Q6) How is TDS measured?
Using a digital TDS meter or via electrical conductivity methods (EC). Many meters convert EC to estimated TDS.
Q7) Does RO eliminate TDS?
Yes — RO can remove a large portion of dissolved solids (80–90% or more) by forcing water through a membrane.
Q8) Will UV / UF remove TDS?
No. UV kills microbes; UF filters particles. Neither effectively removes dissolved salts or ions (i.e. TDS).
Q9) Does a water softener reduce TDS?
No — softeners exchange hardness ions (like Ca/Mg) for sodium or potassium. The total number of dissolved ions (TDS) remains the same or may even increase slightly.
Q10) Does boiling water reduce TDS?
No — boiling removes microbes but does not remove dissolved solids; it may even concentrate them slightly as water evaporates.
Q11) How often should I test TDS in my system?
Monthly is a good practice. You can also test after filter/membrane replacements or if taste / performance seems off.
Q12) What is the ideal output TDS for Livpure’s system?
Our goal is to deliver water in the healthy mineral range, typically in the 100–300 ppm region (or as appropriate per local source) for optimal taste and health.
Q13) Will lowering TDS always cost more water / energy?
Yes, more aggressive purification (e.g. deep RO) uses more pressure and produces more reject water. That’s why balance and smart control matter.
Q14) Is purified water with zero TDS safe?
Pure water (very low TDS) is not “unsafe,” but may not taste pleasant and lacks beneficial minerals. Many systems add minerals back for better taste.
Q15) What steps can I take if my source water TDS is extremely high (e.g. >1000 ppm)?
Use a robust RO + multistage filtration system, maintain filters well, consider periodic checks for membrane health. Use app monitoring to ensure performance.
