What Is an Aerobic Reactor Tank?
An aerobic reactor tank is a component in biological wastewater treatment systems where organic contaminants are decomposed by aerobic microorganisms in the presence of oxygen. Typical aerobic treatment processes include activated sludge systems, trickling filters, sequencing batch reactors (SBR), and aerobic membrane bioreactors (MBR). These systems rely on consistent oxygen transfer, microbial activity, and tank integrity to achieve high treatment efficiency.
Aerobic reactor tanks must:
Maintain structural integrity under continuous wet conditions
Withstand corrosive environments due to biological byproducts
Facilitate oxygenation and mixing without surface degradation
Provide hygienic surfaces to avoid biological adhesion and scaling
Ensure long-term performance with minimal maintenance
To meet these requirements, the choice of construction material and protective coatings is critical—not just for structural strength, but also for biological safety and operational longevity.
Glass-Fused-to-Steel (GFS): The Ideal Material for Aerobic Reactor Tanks
Glass-Fused-to-Steel (GFS) technology represents one of the most advanced and durable solutions for aerobic reactor tank applications. GFS tanks combine the mechanical strength of steel with the chemical resistance and inert properties of glass, resulting in a composite material that excels in corrosive, biological, and wet environments.
How GFS Works
Steel panels are coated with a specially formulated glass and fired at high temperatures (between 820°C and 930°C). During this process, the molten glass fuses to the steel surface, forming a permanent, inorganic bond that creates a continuous, smooth, and chemically inert surface. This fusion process imparts several distinct advantages:
Exceptional corrosion resistance
Complete gas and liquid impermeability
Smooth, non-abrasive surfaces that resist biological adhesion
Superior resistance to chemical and biological attack
Long service life with minimal maintenance
These properties make GFS technology particularly suited to aerobic reactor tanks — where wet, oxygenated, and microbially active environments can aggressively attack ordinary coatings and materials.
Key Advantages of GFS Aerobic Reactor Tanks
1. Superior Corrosion Resistance
Aerobic reactors encounter dissolved oxygen, organic acids, nutrients, and microbial metabolites that can aggressively corrode conventional concrete or painted steel tanks. The glass surface in GFS tanks remains inert in such environments, preventing breakdown and maintaining structural integrity over decades.
2. Non-Porous and Hygienic Surface
The smooth, glossy interior surface of GFS tanks prevents solids or biofilm from adhering, facilitating easier cleaning, reduced odor, and uninterrupted biological activity. This surface characteristic reduces maintenance requirements and supports hygienic operation—especially important in municipal and food-related wastewater treatment.
3. Gas and Liquid Impermeability
Glass-Fused-to-Steel provides a completely impermeable barrier, eliminating micro-leak paths that can compromise tank performance or allow environmental contamination.
4. Structural Strength and Durability
The steel substrate provides robust mechanical strength, enabling GFS tanks to withstand internal loads, mixing forces, temperature variations, and external environmental stresses without cracking or sagging.
5. Extended Service Life
With a design service life of 30 years or more, GFS aerobic reactor tanks far exceed the expected lifetimes of many alternative materials, minimizing lifecycle costs and replacement needs.
6. Modular Bolted Design
Center Enamel’s aerobic reactors utilize a modular, bolted panel assembly, enabling:
Faster and safer on-site construction
Reduced dependence on weather conditions
Flexibility for relocation, expansion, or capacity future-proofing
Efficient transport to remote or constrained project sites
This modular approach also allows for precise quality control during manufacturing and consistent repeatability across global projects.
