Commercial RO Plant Manufacturers

Commercial RO plants are water treatment systems that use reverse osmosis to remove salts and other contaminants from water. Reverse osmosis pushes water through a semi-permeable membrane to filter out impurities. There are several commercial RO plant manufacturers and suppliers but Netsol Water is the leader and leading from the front in this industry.

Commercial RO plants are used in many industries:

  • Food and beverage production
  • Pharmaceutical manufacturing
  • Power generation
  • Desalination of seawater
  • Wastewater treatment

Commercial RO plants provide large volumes of purified water for these industries.

How do Commercial RO Plants Work?

Commercial RO plants work in multiple stages:

  1. Pre-treatment: The feed water first goes through filters to remove large particles, sediments, and chlorine that could damage the membranes.
  2. RO Membranes: The pre-treated water is then pushed through semi-permeable membranes at high pressure. The membranes allow water molecules to pass through but trap dissolved solids, salts, organics, and other contaminants.
  3. Post-treatment: The purified permeate water may go through final polishing steps like remineralization before being sent to storage tanks.

The concentrated waste stream with the removed contaminants is flushed away.

Commercial RO plants are highly automated systems with controls to optimize performance.

Features of Commercial RO Plants

  • Proven pre-treatment like multi-media filters, activated carbon filters
  • Advanced membranes with high salt rejection
  • Membrane array design for easy maintenance
  • Corrosion-resistant materials like super duplex stainless steel
  • Skid-mounted compact plants or larger concrete/RCC structures
  • Automated controls with PLC and SCADA
  • High recovery rates to minimize wastewater
  • Energy recovery devices to reduce operating costs
  • NSF/FDA/CE certified components for safety
  • Modular and expandable for future capacity increases
