SWRO & BWRO Desalination Plant Electromechanical Installations in Ma’aden

Project Overview

The Electromechanical Installations for the 15 MLD (Million Liters per Day) SWRO & BWRO Desalination Plant is a highly specialized industrial water infrastructure project in Ras Al Khair City. Executed for Ma’aden Phosphate Company under the engineering and technological framework of SUEZ, this project focuses on the physical construction and integration of a dual-technology desalination facility. By combining Seawater Reverse Osmosis (SWRO) and Brackish Water Reverse Osmosis (BWRO), the plant is engineered to deliver 15,000 cubic meters of ultra-pure water daily to sustain Ma'aden's demanding phosphate processing operations.

Scope of Work

This project is strictly focused on the electromechanical execution phase, transforming SUEZ’s dual-feed process design into a fully integrated, operational facility. The core responsibilities include:

  • Mechanical Assembly & Rigging: Precision mounting, leveling, and securing of heavy-duty equipment for two distinct treatment trains, including massive SWRO and BWRO skids, high-pressure feed pumps, and Energy Recovery Devices (ERDs).

  • Specialized Piping Integration: Fabrication and installation of complex, dual-grade piping networks. This requires specialized welding of high-grade stainless steel (such as Super Duplex) to withstand the corrosive, high-pressure Arabian Gulf seawater for the SWRO train, alongside industrial-grade UPVC/CPVC for the BWRO lines, chemical dosing, and permeate distribution.

  • Electrical & Control Systems: Complete deployment of the plant's electrical backbone, encompassing Motor Control Centers (MCC), variable frequency drives (VFDs) for pump optimization, extensive cable routing, and the wiring of sensitive field instruments (flow meters, pressure transmitters, conductivity sensors).

  • Automation Readiness: Seamlessly integrating all installed electromechanical field devices with the central PLC/SCADA control architecture designed by SUEZ, ensuring automated fail-safes and preparing the plant for smooth process commissioning.

Technical Architecture & Equipment Integration

The installation demands rigorous adherence to Ma'aden's industrial standards and SUEZ's process specifications to manage two different water chemistries simultaneously:

  • Integrated Pretreatment: Mechanical assembly of advanced primary filtration stages, such as Ultrafiltration (UF) or Multimedia Filters (MMF), designed to protect both the SWRO and BWRO membranes from biological and particulate fouling.

  • Dual-Membrane Arrays: Rigorous assembly of the distinct reverse osmosis blocks. This involves exact pressure vessel alignment and secure high-pressure manifold connections for both the primary SWRO pass and the secondary/brackish BWRO pass to maximize overall recovery rates.

  • Targeted CIP & Dosing Stations: Installation of dedicated, automated Clean-In-Place (CIP) units and precision chemical dosing systems tailored to the specific scaling and fouling tendencies of each membrane type.

Strategic Impact

By executing the electromechanical installations to the exacting tolerances required by both Ma’aden and SUEZ, this project guarantees the structural integrity and operational reliability of a highly complex facility. The flawless mechanical and electrical integration ensures that the dual SWRO/BWRO design operates at peak energy efficiency, minimizing future maintenance downtime and securing the critical, high-purity water supply required for Ma'aden’s continued industrial expansion.
