Converting Gelatin Filter Press Sludge into a Dry, Manageable Material

Technical Snapshot

Problem

• The gelatin manufacturing plant generated over 650 kg/hr of wet filter press sludge at approximately 70% moisture.
• Wet sludge created high disposal cost, storage issues, housekeeping concerns, and environmental compliance pressure.
• The plant was dependent on third-party sludge disposal, resulting in recurring operating cost.
• In wet form, the sludge was difficult to handle, transport, and manage within the facility.

Proposed Solution

• Gem Drytech engineered a customized BELTOTHERM belt dryer specifically for continuous gelatin sludge handling.
• The system was integrated with the plant’s existing flue gas source to utilize available waste heat.
• This eliminated the need for additional fuel while enabling controlled and continuous drying.
• The dryer was designed for smooth sludge movement, stable moisture reduction, and reliable long-term operation.

Result

• Moisture was reduced from approximately 70% to around 10%.
• Dependency on third-party sludge disposal was significantly reduced.
• The sludge was converted into a dry, manageable material.
• Handling, storage, housekeeping, and environmental compliance improved.
• Existing flue gas was utilized, resulting in no additional fuel requirement for drying.
• The plant achieved a more sustainable and cost-effective in-house sludge management process.

Conclusion

Flue gas-integrated BELTOTHERM belt drying helped the gelatin plant convert a high-moisture sludge disposal problem into a controlled, cost-effective, and sustainable in-house process.

Applicability

Well suited for gelatin plants, ossein processing units, food-processing sludge, pharmaceutical ETP sludge, filter press sludge, and other high-moisture sludge streams where waste heat or flue gas is available.
