ZJ Composites Water Treatment Systems

ZJ Composites (Zhaojia Composite Materials Co., Ltd.), a leading global supplier of fiberglass products, has successfully delivered a major shipment of high-performance FRP (Fiberglass Reinforced Polymer) Pressure Vessels for a large-scale overseas water treatment project.

Designed to withstand extreme operating pressures and highly corrosive environments, these FRP pressure vessels provide a ultra-durable, cost-effective, and long-lasting filtration solution for modern industrial and municipal water infrastructure.

Product Highlights & Key Specifications

Engineered using advanced filament winding technology and premium-grade vinyl ester resin, ZJ Composites’ FRP pressure vessels are built to surpass traditional steel and rubber-lined tanks:

• Superior Corrosion Resistance: Unmatched resistance to harsh acids, alkalis, saline solutions, and industrial wastewater, eliminating rust and liquid contamination.

• High Operating Pressure & Safety Margin: Precision-wound glass fibers ensure high structural strength, tested to endure design pressures up to 150 PSI (1.0 MPa) with a high safety factor.

• Smooth Inner Wall & Anti-Fouling: Features an impermeable seamless PE/FRP inner liner with low friction loss, preventing biofilm accumulation and scale build-up.

• Lightweight & High Strength: Weighing only 1/4 of equivalent steel tanks, dramatically reducing shipping costs and simplifying on-site handling and installation.

• UV & Weather Resistance: Outer layers are treated with UV-inhibiting coatings for long-term outdoor installation under extreme climatic conditions.

Typical Application Scenarios

ZJ Composites FRP pressure vessels are widely used across high-standard water and wastewater treatment systems, including:

• RO (Reverse Osmosis) Desalination Plants: Pre-treatment sand and carbon filtration in high-salinity marine environments.

• Industrial Wastewater Treatment: Chemical, pharmaceutical, and textile water recycling systems handling aggressive liquids.

• Municipal Water Supply & Filtration: Large-scale quartz sand, activated carbon, and ion exchange softening tanks.

• Ultra-Pure Water Systems: Semiconductor and electronics manufacturing facility water purification lines.
