Reverse Osmosis (RO) is one of the most effective membrane-based technologies for water purification and desalination. Using semi-permeable membranes and high-pressure operation, RO systems remove a significant portion of dissolved salts, minerals, heavy metals, microorganisms, and other contaminants from water.
Mojan RO packages are engineered according to raw water quality, water analysis, required treatment capacity, and target product water quality. Before entering the RO membranes, the feed water passes through appropriate pretreatment and filtration stages to reduce suspended solids and other contaminants that could affect membrane performance.
The pretreated water is then pressurized by a high-pressure pump and directed to the RO membrane vessels. During the membrane separation process, the feed water is divided into two main streams:
- Permeate: Treated water passing through the RO membranes
- Reject / Concentrate: Concentrated stream containing the rejected dissolved contaminants
General RO Treatment Process
The overall treatment process typically includes the following stages:
Raw Water → Pretreatment → Filtration → Water Conditioning → High-Pressure Pump → RO Membranes → Permeate + Concentrate
The exact treatment configuration can be customized according to feed water characteristics, required recovery, product water quality, and project requirements.
Mojan RO System Configurations
Mojan RO systems can be designed and manufactured in a wide range of capacities, from compact and semi-industrial units to high-capacity industrial water treatment plants.

Customized RO Design by Mojan
Proper RO system design requires detailed evaluation of the feed water and operating conditions. Mojan designs each RO package based on parameters such as raw water analysis, flow rate, TDS and salinity, required recovery, target product water quality, operating pressure, temperature, and project-specific requirements.
Based on these parameters, the appropriate pretreatment system, filtration stages, high-pressure pump, membrane type and arrangement, instrumentation, control system, and cleaning equipment can be selected.
This customized approach helps achieve reliable treatment performance, optimized water recovery, efficient operation, and longer membrane service life.
