Glass-Fused-to-Steel Tank for Palm Oil Wastewater Treatment Projects

GFS Tank for Palm Oil Wastewater Treatment: Dealing With High-Strength Effluent
A GFS tank for palm oil wastewater treatment uses a vitreous enamel coating fired at 820 to 930 degrees C that resists the acidic, high-BOD, high-temperature effluent better than painted steel, provided the enamel grade matches the stream chemistry.
Palm oil mill effluent is hot, acidic and biologically aggressive, so the tank lining decides the project life. This article explains why glass-fused-to-steel is a sound choice and what to specify.
Technical Explanation
Why the coating matters
· POME carries organic acids and sulfides that attack ordinary paint films; the inert glass layer on GFS does not soften or peel in that environment.
· The enamel formula is chosen for the expected pH and chloride range, which is why a generic coating spec is a mistake for this duty.
Process fit
· GFS tanks serve equalization, anaerobic digestion and treated-effluent duty in palm mills because they bolt together fast and resist the wet, tropical exposure.
· Panel stiffness and sealant grade are selected for the retained liquid density and any gas pressure from digestion.

Frequently Asked Questions (FAQ)
Q: Why not painted welded steel for POME?
A: POME acids and sulfides quickly undercut paint; GFS vitreous enamel is far more stable in that chemistry.
Q: Does GFS handle the heat of palm effluent?
A: The enamel is fired at 820 to 930 degrees C so process warmth is well within its service range.
Q: Can the tank hold biogas pressure?
A: Yes when specified as gas-tight with a suitable roof and sealant for anaerobic duty.
Q: Is GFS faster to build than concrete?
A: Bolted GFS panels assemble on site much faster than cast concrete and need no curing wait.
Q: What capacity suits a palm mill?
A: Equalization and digestion volumes scale with throughput; GFS tanks are built modular from tens to tens of thousands of cubic metres.
Q: How is corrosion at the waterline handled?
A: The continuous enamel layer removes the coating breakdown that causes waterline corrosion in painted tanks.
For palm oil wastewater, the tank lining is the project. Glass-fused-to-steel earns its place where acidic, warm, high-BOD effluent would destroy lesser coatings.
