The thickening drum – also called a rotary drum or filter drum – is essential equipment for optimizing the treatment of sludge and effluents, increasing the concentration of suspended solids and reducing operating costs.
 ⚙ How does it work?
 ✔ The perforated drum or drum with filter screen rotates slowly.
 ✔ The water present in the mud passes through the holes or the screen.
 ✔ Solids are retained and accumulate on the surface of the drum.
 ✔ The thickened sludge goes to the next dewatering stage.
 ✅ Main Benefits
 🔹 Greater efficiency in solid-liquid separation
 🔹 Reduction in sludge volume → Lower transportation and disposal costs
 🔹 Continuous and automated process
 🔹 Versatile application → Water treatment plants, industries and waste management
