Commercial RO Plant Manufacturers in Noida

May 6, 2024by Netsol Water

A commercial RO plant is a water purification system. It removes dissolved solids from water. This produces highly purified water for industrial & commercial use. Here are a few commercial RO plant manufacturers in Noida.

How Does a Commercial RO Plant Work?

The RO process works by pushing water through semi-permeable membranes.

First, the feed water enters the pretreatment stage. Here, chlorine, particles and hardness are removed.

Next is the RO membrane stage. The pretreated water is pushed through spiral-wound membranes at high pressure. Up to 99% of dissolved solids are rejected.

The purified permeate stream exits as product water. The concentrated reject stream goes to drain.

Post-treatment follows, like remineralization if needed. The treated water is then stored for Commercial use.

Need for Commercial RO Plant

Many industries require pure water in their processes. This includes pharmaceuticals, food/beverage, power, electronics, and more.

Municipal water often contains dissolved solids, hardness and other contaminants. This can damage equipment and spoil products.

Commercial RO plant provides a reliable way to purify water on-site. This ensures a consistent supply of high-quality process water.

As Commercial demand grows, so does the need for RO systems. This creates opportunities for Commercial RO plant manufacturers.
