As global demand for clean and safe water continues to rise, Commercial RO Plants and Industrial RO Plants are becoming critical investments across industries, hospitals, hospitality, and municipal infrastructure. This FAQ-style guide addresses the most commonly asked queries from entrepreneurs, facility managers, and water treatment professionals looking to install or expand RO plants in India and worldwide.

  1. What is a Commercial RO Plant (also called Commercial Reverse Osmosis System) and how does it differ from an Industrial Reverse Osmosis Plant?

    A Commercial RO Plant is typically used in medium-scale settings like hotels, schools, hospitals, and offices, providing water purification capacities ranging from 100 LPH to 1000 LPH. An Industrial RO Plant serves high-volume applications (e.g., bottling plants, pharmaceuticals, food processing), with output exceeding 1000 LPH and advanced automation. The scale, pressure ratings, and robustness differ significantly.
  2. What are the key components of an Industrial RO Plant?

    An Industrial RO Plant includes:
  • Raw water pump
  • Multi-grade filtration
  • Activated carbon filter
  • Antiscalant dosing system
  • High-pressure pump
  • Reverse osmosis membranes
  • Control panel with PLC/SCADA (optional)
  • Storage tank

    Each part plays a vital role in removing impurities, improving output quality, and protecting the system's longevity.
  1. How much area is required to install a Commercial RO Plant?

    The installation space for a Commercial RO Plant depends on capacity. For 250–500 LPH models, a floor space of 6x4 feet is typically sufficient. Higher capacity may require 100–200 sq. ft., especially if pre-filtration, storage tanks, and post-treatment units are included.
  2. What is the cost of setting up a Commercial RO Plant in India (including RO plant setup cost, reverse osmosis plant price, and RO plant machine cost)?

    Costs vary by capacity and specifications. For instance, a 250 LPH Commercial RO Plant may start from ₹60,000 to ₹90,000. Larger models can cross ₹5 lakhs depending on automation and design. For precise pricing, buyers should contact Dharmanandan Techno Project Pvt. Ltd., a trusted manufacturer of RO plants.
  3. Can a Commercial RO Plant be used for a packaged drinking water RO plant business or mineral RO plant startup?

    Yes, a Commercial RO Plant of at least 500 LPH is suitable for a small-scale bottled water setup. However, BIS certification, UV sterilization, ozone dosing, and bottle-filling machinery are also required to comply with Indian standards.
  4. How long does it take to install an Industrial RO Plant?

    Installation of an Industrial RO Plant typically takes 10–30 days depending on capacity, site readiness, utility availability (power/water), and customization requirements.
  5. What are the recurring maintenance and operating costs for Industrial RO Plants (including reverse osmosis plant operating cost)?

    Industrial RO Plant maintenance includes membrane replacement (every 1.5–3 years), filter media, pump servicing, and electrical part replacement. Annual maintenance contracts (AMCs) help manage this, costing around 5–10% of the system's value per year.
  6. What are the power requirements for a Commercial RO Plant?

    Power consumption depends on pump horsepower and automation level. A basic 250–500 LPH Commercial RO Plant consumes around 1–2 kW per hour, while larger systems may need up to 5–10 kW.
  7. Is financial assistance or subsidy available to set up Commercial or Industrial RO Plants in India?
