Wastewater treatment involves the collection and storage of used water and the removal of pollutants it contains so that it can be converted into effluent and recycled back into the water grid or the environment. 

Why Choose GFS Wastewater Treatment Tanks?

Corrosion Resistance for Harsh Waste Streams

Wastewater often contains acids, alkalis, oils, and chemicals that degrade traditional tanks. GFS tanks’ glass-fused coating forms an inert barrier, preventing rust and pitting—even when exposed to high-chloride sewage or industrial byproducts.

Optimized Treatment Efficiency

Smooth, non-porous glass surfaces reduce sludge adhesion, making cleaning and maintenance easier. This minimizes downtime and ensures consistent performance in primary (sedimentation), secondary (biological), or tertiary (filtration) treatment stages.

Compliance with Global Standards

Our tanks meet strict regulations for wastewater handling, including:

• ISO 14001 (environmental management)

• EPA 40 CFR (U.S. wastewater discharge limits)

• EN 12573 (European standards for concrete/steel tanks)

• NSF/ANSI 61 (safe for potable water reuse in some cases).

Scalable & Customizable

Whether you need a small municipal lift station tank (500L) or a large industrial clarifier (100,000L+), GFS tanks adapt to your flow rate, space constraints, and treatment goals. Add features like mixers, diffusers, or sludge thickeners to match your process.

Long Lifespan, Low Lifecycle Costs

With a 25–30 year lifespan (vs. 10–15 years for fiberglass or steel-only tanks), GFS tanks reduce replacement frequency. Their low maintenance needs (occasional inspections, cleaning) further lower long-term costs.

What Are Wastewater Treatment Tanks?

Wastewater treatment tanks, a type of custom GFS tank, are specialized storage and processing vessels engineered to manage sewage, industrial effluent, sludge, and other contaminated water streams. Built with Glass Fused to Steel (GFS) technology—combining carbon steel’s structural strength with a vitreous enamel glass coating—these tanks resist corrosion, chemical degradation, and microbial buildup, making them ideal for municipal, industrial, and commercial wastewater treatment applications.

Top Applications of Wastewater Treatment Tanks

• Municipal Sewage: Primary sedimentation tanks, secondary clarifiers, and sludge holding tanks for city sewer systems.

• Industrial Effluent: Treatment of chemical, food processing, or oil refinery wastewater (e.g., neutralization, flocculation).

• Commercial Facilities: Hotels, hospitals, and campuses needing on-site sewage pretreatment before municipal discharge.

• Agricultural Runoff: Storing and treating fertilizer-laden water to prevent environmental contamination.

• Biogas Production: Anaerobic digesters for converting sludge into renewable energy (biogas).

  
  

Key Features of Our Wastewater Treatment Tanks

How to Choose the Right Wastewater Treatment Tank

When selecting a tank, prioritize these factors:

• Waste Type: Corrosive industrial waste needs specialized coatings (e.g., high-chloride resistant enamel).

• Flow Rate & Capacity: Match the tank size to your peak inflow (e.g., 10,000L/day for a small town).

• Treatment Stage: Primary tanks require sedimentation space; secondary tanks need aeration/mixing features.

• Space Constraints: Cylindrical (space-efficient) or rectangular (easier access) designs available.

• Budget & Longevity: GFS tanks cost more upfront but save money through reduced maintenance and longer lifespan.

  
  

FAQs About Wastewater Treatment Tanks

• Q: Can GFS tanks handle hydrogen sulfide (H2S) in sewage?
     A: Yes—our glass-fused coating resists H2S corrosion, a common issue in anaerobic sewage environments.

• Q: Do you offer tanks for sludge thickening or dewatering?
     A: Yes—we design custom tanks with agitators, polymer injection systems, and filter presses for sludge processing.

• Q: Are GFS wastewater tanks compatible with biological treatment processes?
     A: Absolutely—the smooth, non-toxic surface supports bacterial growth critical for aerobic/anaerobic digestion.

• Q: How often do GFS wastewater tanks need maintenance?
     A: Routine inspections (every 6–12 months) and occasional cleaning are typically sufficient—far less than traditional tanks.
