Glass Fused to Steel (GFS) Effluent Holding Tanks by Shijiazhuang
Zhengzhong Technology Co., Ltd (Center Enamel): Durable and
Corrosion-Resistant Solutions for Efficient Wastewater Management
Effluent holding tanks are critical components in wastewater
treatment systems, serving as containment vessels for industrial,
municipal, and agricultural effluents awaiting treatment or safe
disposal. To ensure operational efficiency and environmental
compliance, these tanks must resist chemical corrosion, abrasion,
and structural stress. Shijiazhuang Zhengzhong Technology Co., Ltd,
under the brand Center Enamel, specializes in manufacturing
advanced Glass Fused to Steel (GFS) effluent holding tanks,
delivering exceptional durability, hygiene, and operational
reliability.
Understanding Glass Fused to Steel (GFS) Technology
GFS technology involves the fusion of a specially formulated glass
enamel coating onto both interior and exterior surfaces of steel
panels in a batch process fired at temperatures around 820–930°C.
This process forms a permanent, chemically inert, and physically
integral bond, combining steel's structural strength with glass's
exceptional corrosion and abrasion resistance.
This robust composite material is ideal for demanding effluent
containment, where harsh chemical environments often lead to rapid
degradation of conventional tanks.
Key Features and Specifications of Center Enamel GFS Effluent
Holding Tanks
- Durable Glass Enamel Surface:
- Thickness: 0.25 – 0.45 mm coating on both sides of steel plates.
- Colors: Black blue, forest green, cobalt blue, grey olive, desert
tan, etc.
- Hardness: Mohs scale ~6.0 providing significant abrasion
resistance.
- Adhesion Strength: Greater than 3450N/cm² for long-lasting coating
integrity.
- Steel Substrate:
- Plate thickness ranging from 3 mm to 12 mm depending on tank design
and capacity.
- Hot-rolled steel, surface prepared by shot blasting to ensure
coating adhesion.
- Structural Design:
- Modular, bolted panel construction enabling rapid onsite assembly.
- Tank sizes customizable from small capacity to several thousand
cubic meters.
- Roof options include fixed, conical, or domed, constructed with
corrosion-resistant materials.
- Environmental Performance:
- Highly resistant across a pH range of 1 to 14, accommodating
diverse effluent chemistries.
- Impermeable to liquids and gases, preventing leaks and
contamination.
- Suitable for outdoor exposure with excellent UV and weather
resistance.
- Certifications and Compliance:
- ISO 9001 Quality Management System.
- ISO 28765, NSF/ANSI 61 - Safe for potable water environments.
- WRAS, FM Approvals, NFPA, CE/EN1090 certifications.

Applications of GFS Effluent Holding Tanks
- Municipal Wastewater: Temporary storage of sewage, stormwater runoff, and combined sewer
overflows before biological or chemical treatment.
- Industrial Effluents: Safe containment of acidic, alkaline, or chemically aggressive
wastewater from chemical, petrochemical, pharmaceutical, mining,
food processing, and metal industries.
- Agricultural Waste Management: Storage of liquid manure, slurry, and effluent from farm
operations prior to treatment or spreading.
- Landfill Leachate: Storage and containment of highly contaminated liquids from
landfill sites preventing environmental contamination.
- Biogas Plants: Holding of digestate and process liquors in anaerobic digestion
operations.
- Firewater Runoff: Tanks built to hold contaminated firewater for treatment before
discharge.
Advantages of GFS Effluent Holding Tanks
- Superior Corrosion Resistance: The glass coating resists acids, alkalis, solvents, and biological
agents that rapidly degrade traditional steel tanks.
- Extended Service Life: Proven operational longevity exceeding 30 years reduces long-term
capital and operational expenditures.
- Low Maintenance: Non-porous glass surface prevents sludge adherence and bacterial
growth, simplifying cleaning routines and reducing downtime.
- Structural Strength: Steel substrate maintains mechanical integrity to resist internal
pressures, soil loads, and seismic events.
- Leak Prevention: Modular bolted design with gasketed joints ensures containment of
hazardous liquids and vapors.
- Sustainability: Durable materials reduce environmental footprint by minimizing the
frequency of tank replacements and repairs.
