Decoding Your Tap Water: A Technical Guide to Selecting Domestic RO Systems in India

Michel May 5, 2026
    • The TDS Threshold: Explain that RO is only necessary for TDS above 500 ppm. For lower TDS, a UV+UF system is better to retain natural minerals.

    • Heavy Metal Concerns: Discuss how industrial runoff in cities like Delhi, Bangalore, and Kanpur introduces Lead, Arsenic, and Mercury—requiring specific membrane grades like those found in the Domestic Systems category.

    • The Role of the Pump: Explain why a 100 GPD pump is superior for high-rise apartments with low inlet pressure compared to standard 75 GPD pumps.

    • Membrane Life Factors: List the top three things that “kill” a domestic membrane: high chlorine, scale buildup (hardness), and lack of periodic flushing.

  • The Solution: Focus on how RomegaMart offers “customizable” domestic systems where users can choose membranes (like Vontron or Dow) suited to their specific pin code.

  • Don’t guess your water quality. Browse our Domestic Systems designed for high-TDS Indian water.
