Mobile Water Treatment & Demineralization Skids in Central Operating Area

Project Overview

This highly complex and strategic project involves the rapid deployment, rental, and operation of mobile water treatment skids across seven major thermal power plants in the Saudi Electricity Company's Central Operating Area (COA). The core engineering challenge and objective is to safely and efficiently convert Treated Sewage Effluent (TSE) into ultra-pure Demineralized (Demin) water. Supplying these mega-facilities (PP09, PP10, PP12, PP13, PP14, PP Hail, and PP Qassim) with continuous high-purity water is critical for their high-pressure boiler feed systems and cooling operations, ensuring grid stability across the central region while conserving precious groundwater resources.

Scope of Work

  • Rapid Mobilization & Setup: Logistics, site preparation, and rapid deployment of mobile, skid-mounted treatment units to seven geographically dispersed power generation facilities.

  • Advanced Pre-Treatment of TSE: Operating robust pre-treatment stages (such as Ultrafiltration and multimedia filtration) specifically designed to handle the high organic loads, suspended solids, and bio-fouling potential inherent in Treated Sewage Effluent.

  • RO & Demineralization Operations: Operating multi-pass Reverse Osmosis (RO) and subsequent demineralization stages (Electrodeionization - EDI) to strip all dissolved solids and achieve the stringent ultra-low conductivity and silica parameters required for boiler feed water.

  • Preventive Maintenance & CIP: Executing aggressive membrane management strategies, including frequent chemical Clean-In-Place (CIP) protocols and automatic resin regeneration, to combat the rapid fouling rates typically associated with TSE feed water.

  • Quality Assurance & Grid Integration: 24/7 process monitoring, laboratory testing, and seamless integration of the mobile skids’ output directly into each power plant's existing demineralized water storage and distribution networks.

Technological Impact

This project represents a major leap in industrial circular economy and water sustainability. By successfully utilizing advanced membrane technology to upgrade municipal Treated Sewage Effluent (TSE) into ultra-pure boiler feed water, the project massively reduces SEC's reliance on deep-well aquifers and municipal freshwater for power generation. Furthermore, the use of mobile skid-mounted architecture provides unparalleled operational agility, allowing SEC to rapidly scale water production up or down at any of the seven mega-plants based on seasonal electrical demand or emergency maintenance requirements.
