Client:

Tianjin Nangang Industrial Zone (Fictional Client for demonstration purposes, representing the project’s end-user).

Challenge:

• Water Scarcity: The Tianjin region faces significant freshwater challenges, impacting industrial growth and community well-being.
• Stringent Water Quality Requirements: Both industrial processes and potable water demand high-purity water, exceeding the capabilities of conventional water sources.
• Environmental Regulations: Strict discharge regulations require environmentally sound desalination processes.
• Large-Scale Capacity: The need for a plant capable of producing 150,000 TPD of desalinated water presented a significant engineering challenge.

Globaluf’s Solution:

Globaluf provided a comprehensive, end-to-end solution encompassing design, engineering, manufacturing, installation, and commissioning. The core of the system features:

• Advanced Pre-treatment with Ultrafiltration (UF): Globaluf’s state-of-the-art UF system effectively removes suspended solids, colloids, and microorganisms, protecting the downstream RO membranes and extending their lifespan. This pre-treatment is crucial for maintaining consistent RO performance and minimizing maintenance.
• High-Performance Reverse Osmosis (RO) System: A multi-stage RO system, designed for optimal energy efficiency and water recovery, removes dissolved salts and other impurities to produce high-quality permeate. The system incorporates advanced membrane technology for superior performance and longevity.
• Customized Design and Engineering: Globaluf’s experienced team tailored the entire system to meet the specific needs of the Tianjin Nangang Industrial Zone, considering factors such as feedwater quality, energy costs, and space constraints. The design emphasized modularity for future expansion and ease of maintenance.
• Durable Construction: The system utilizes duplex stainless steel for intake and concentrate pipelines, ensuring corrosion resistance and long-term reliability. HDPE materials are used for product water piping, selected for their durability and chemical inertness.
• Stringent Quality Control: Globaluf’s manufacturing facility adheres to the highest quality standards, ensuring the delivery of reliable and durable equipment.

Key Features of the Globaluf System:

• Optimized Design: Finalized design incorporating “reinforced product water end and tenon positioning of supports.”
• Premium Materials: Duplex stainless steel for inlet and concentrate pipelines, TIG welding with argon shielding, and single-sided welding with double-sided formation.
• Modular Support Structure: Four columns and three layers totaling 12 support units, with numbered and positioned supports.

Results:

• Reliable Water Supply: The 150,000 TPD desalination plant provides a secure and sustainable source of high-quality water for the Tianjin Nangang Industrial Zone.
• Improved Water Quality: The desalinated water meets stringent quality standards, supporting various industrial applications and potable water needs.
• Reduced Environmental Impact: The plant incorporates energy-efficient technologies and minimizes brine discharge, contributing to environmental sustainability.
• Enhanced Operational Efficiency: The modular design and robust construction ensure ease of maintenance and long-term reliability.
