Why is R.O. Preferred for Water Purification?

While technologies like UV and ultrafiltration are deployed sometimes, reverse osmosis remains the absolute choice for reliable water purification across industry domains. Reasons that make RO systems the most sought-after include:

  • Multi-stage Filtration: Combination of mechanical & chemical pre-filtration before RO allows effective removal of micro- as well as macro-impurities.
  • Superior Purity: Industry-accepted benchmark of achieving up to 99% contaminant removal through precision filtration
  • Energy Efficient Models: Inbuilt energy recovery components conserve electricity, leading to lowered operational costs
  • Minimal Manual Control: Reduced reliance on human intervention through remote monitoring or self-regulating automation features
  • Easy Scalability & Customization: Wide flexibility in sizing and integration with supplementary purification processes like Ultraviolet
  • Better Lifespan: Advanced membrane materials and tightly controlled operations ensure more significant and consistent RO plant longevity

Key Selection Criteria for Commercial RO Plant Buyers

While evaluating options, institutional buyers consider a few vital parameters before selecting any commercial RO system:

  • Brand Reputation & Experience: Accounts for superior build quality, reliability, and technology integration capabilities
  • Output Flow Rate: Matched to daily water consumption levels for optimum utilization without excesses or shortages
  • Raw Water Quality Analysis: Determines appropriate pre-filtration, membrane, and post-treatment accessories for the intended water source
  • Cost Per Litre: Comprehensive estimate covering capital investment and ongoing operational expenses
  • Product Certifications: Globally accepted water quality standards assurance through certifying agencies
  • Maintenance Requirements: Fewer installed components requiring lesser frequency of replacements are desirable


As rising populations strain existing water resources and contamination increases, commercial RO systems provide a high-tech solution through affordable purification and germ removal capabilities. Companies like Netsol, Sewage Treatment Plants, and Commercial RO Plant contribute immensely to providing safe, clean drinking water across Delhi through extensive dealer networks. With advanced R&D capabilities and energy-efficient models, they are poised to consolidate their leadership further in the coming years. For prospective institutional clients, evaluating options on key parameters before finalizing decisions is vital, besides availing of free annual maintenance contracts.
