1.Wastewater Collection & Transportation Pipelines

Pipelines are essential for transporting wastewater from urban and industrial areas to treatment plants. These pipes are exposed to highly corrosive wastewater over extended periods and may face varying pressure conditions.

   ·  Corrosion Resistance: GRE pipes resist chemical and biological corrosion caused by the substances in wastewater, ensuring long-term reliability.

   ·  High-Pressure Tolerance: GRE pipes can withstand the high pressures required in pumping stations and long-distance transport systems, ensuring stable flow.

2. Biological Treatment System Pipelines

Biological treatment involves exposing wastewater to microorganisms in aeration tanks or bioreactors, where organic matter is decomposed, producing corrosive byproducts.

  ·  Chemical Stability: GRE pipes resist acids and gases produced during biological decomposition, preventing leaks and ensuring system integrity.

  ·  Temperature Adaptability: GRE pipes can handle specific temperature ranges required for biological processes, maintaining stable operation.

3. Sludge Treatment Pipelines

Sludge treatment, including concentration, dewatering, and disposal, deals with highly viscous and chemically complex materials.

  ·  Corrosion Resistance: GRE pipes resist the organic acids and chemicals in sludge, ensuring safe and efficient transport.

  ·  High Strength: GRE pipes can withstand the stresses of sludge transport, reducing risks of blockages or rupture.

4.Treated Water Distribution & Discharge Pipelines

After treatment, reclaimed water is either reused for agriculture and industry or discharged into natural water bodies. GRE pipes excel in this stage as well:

  ·  Non-Contaminating: GRE pipes do not release harmful substances, ensuring the quality of treated water.

  ·  High-Efficiency Transport: Smooth inner surfaces reduce fluid resistance, improving transport efficiency.
