Overview

The Reverse Osmosis (RO) System is designed to remove dissolved salts, minerals, and contaminants from water, producing high-quality permeate suitable for industrial reuse, utility services, or process applications in Oil & Gas facilities.
The system ensures reliable operation, high recovery rates, and protection of downstream users through controlled separation and optimized process performance.

System Scope

Reverse Osmosis Systems are engineered as fully integrated packages and typically include the following main components:

  • High-pressure feed pumps
  • RO membrane racks and pressure vessels
  • Membrane elements and interconnections
  • Pre-filtration units (cartridge filters)
  • Chemical dosing systems (antiscalant, pH adjustment, cleaning)
  • Clean-In-Place (CIP) system
  • Permeate and concentrate control valves
  • Pressure, flow, and conductivity instrumentation

Subsystems

High-Pressure Feed Pumping System

Engineering of high-pressure feed pumps and associated piping to provide the required pressure and flow to the membrane array, ensuring stable operation across the full operating envelope.

Engineering of membrane racks, pressure vessels, membrane elements, and interconnections to achieve the required salt rejection and permeate quality, with proper staging and hydraulic balancing.

Engineering of cartridge filters and protection devices to prevent particulate ingress and membrane damage, including differential pressure monitoring and isolation/bypass arrangements.

Engineering of chemical dosing packages (e.g., antiscalant, pH control, dechlorination when required) to control scaling and fouling risk and maintain membrane performance.

Engineering of CIP tanks, pumps, heaters (when required), and recirculation lines to execute cleaning sequences safely and effectively, restoring membrane permeability and extending membrane life.

Engineering of permeate and concentrate lines, control valves, and routing philosophy to manage recovery, maintain stable operating conditions, and interface with downstream reuse/storage or concentrate disposal systems.

Engineering Approach

The engineering of RO systems follows an integrated and performance-driven design approach, focused on water quality, membrane protection, and operational efficiency. Engineering activities begin with the definition of the design basis, including feed water quality, salinity, flow rate, temperature, recovery targets, and permeate specifications.
This approach ensures stable operation, high-quality permeate, and long-term membrane performance.

System Integration

Reverse Osmosis systems are not standalone units, but integral components of the overall water treatment facility, ensuring consistent production of high-quality water.
This integrated design philosophy ensures that, when feed water quality varies or abnormal conditions occur, the RO system responds in a controlled, safe, and coordinated manner—maintaining water quality and overall plant reliability.
