Sludge Drying Case Studies
Real sludge drying case studies from projects across India: the sludge, the technology and the results.
Proven Results From Real Sludge Drying Projects
Real sludge drying case studies from paint, oil and gas, polyester yarn and textile CETP plants across India, each with measured results.
Asian Paints Limited
Visakhapatnam, Andhra Pradesh
Key result: 0.5 TPD · moisture ~75% → <10% · only 73 m² footprint
Cairn India Limited
Barmer, Rajasthan
Key result: 1.1 TPD oily hazardous sludge · 80–90% → <10% moisture · 10–15 m² footprint
Bhilosa Industries Pvt. Ltd.
Silvassa, DNHD
Key result: 4.5–5 TPD · ~80% → ≤10% moisture · ~10–15 kWh/day
NTIEM CETP
Ahmedabad, Gujarat
Key result: 160–200 TPD · up to 85–90% DS · waste heat + solar hybrid
Brandix SEZ
Visakhapatnam, Andhra Pradesh
Key result: ~10 TPD · 100% solar · dried sludge used as cement-kiln fuel

Sludge Drying Case Studies: Frequently Asked Questions
Which industries have Thermarex sludge drying projects served?
Our sludge drying case studies cover paint and coatings manufacturing (Asian Paints), oil and gas (Cairn India), polyester yarn manufacturing (Bhilosa Industries), a textile CETP (NTIEM) and a textile industrial park (Brandix SEZ). We also design systems for chemical, pharmaceutical, food, paper and municipal sludge; see industries we serve.
How much moisture reduction do your projects achieve?
Results depend on the sludge and the technology. Across these projects, inlet moisture of 75–90% was reduced to below 10%, or 85–95% dry solids, cutting sludge weight and disposal volume by roughly 70–90%.
Can solar sludge drying work at large scale?
Yes. Brandix SEZ dries around 10 TPD using 100% solar energy, and NTIEM CETP handles 160–200 TPD by combining solar drying with a waste-heat Multi Layer Mesh Belt Dryer. Solar capacity scales with the site area available.
Can you dry oily or hazardous sludge?
Yes. At Cairn India, a steam-heated Hollow Shaft Paddle Dryer reduces oily hazardous sludge from 80–90% moisture to below 10% in a fully enclosed system, in line with CPCB hazardous waste rules.
Can we visit a reference site?
Yes, reference site visits can be arranged on request. Contact us with your sludge details and location, and we will suggest the most relevant installation to visit.
