Textile ETP Sludge Drying Case Study
Textile ETP Sludge Drying Results at Bhilosa Industries
This textile ETP sludge drying case study covers Bhilosa Industries, a polyester yarn manufacturer in Silvassa, where an automated Thermarex Solar Sludge Dryer handles 4.5–5 TPD and beats its design target.
Project Overview
Facts and Figures
The Textile ETP Sludge Drying Challenge
- Moderate to high sludge generation (up to 5 TPD with fluctuations)
- High moisture (~80%) increasing disposal cost
- Requirement for scalable and continuous drying system
- Need for efficient material handling (feeding + discharge)
- Industrial requirement for consistent dryness
The Solution
- Installation of large-scale Solar Sludge Dryer
- Drying area: ~940 m² (8 m width × ~100 m length)
- Continuous turning mechanism for uniform drying
- Integrated systems: Sludge feeding hopper, Belt conveyor, Bucket elevator, Delivery chute system
- Semi-automated operation for optimized performance
Results & Benefits
- Achieved higher-than-design performance (≤10% moisture)
- Significant reduction in sludge volume and disposal cost
- Low energy consumption compared to thermal systems
- Scalable system for fluctuating loads
- Improved handling via integrated conveying systems
Why the Solar Sludge Dryer?
With a steady 4.5–5 TPD load and room for a ~940 m² greenhouse, solar drying gave the lowest running cost: about 10–15 kWh of power a day, far below a thermal dryer, with integrated feeding and conveying for easy handling.

What dryness did the textile ETP sludge drying system achieve?
The system was designed for below 20% moisture and now achieves 10% or less, beating its design target and cutting sludge volume and disposal cost significantly.
How much power does it use?
About 10–15 kWh per day, roughly 300 units a month, because the drying energy comes from the sun rather than fuel or steam.
Can it handle fluctuating sludge loads?
Yes. The system is scalable for loads that vary up to 5 TPD and uses a feeding hopper, belt conveyor, bucket elevator and delivery chute to keep handling simple. ETP sludge must still be managed under CPCB and SPCB rules.
