CD Dryer: Continuous Sludge-to-Solids Conversion
Feeds directly from dewatering equipment
Filter press or centrifuge cake at 80–85% thermal efficiency converts straight into dry flake or powder without intermediate handling.
Continuous discs resist caking
Rotating heated discs keep sludge moving so it can't build up and clog the chamber the way static dryers do with cohesive cake.
Enclosed design contains odor
A sealed chamber keeps sludge-drying odor inside the process rather than in the plant, a common requirement near residential areas.

Vacuum Paddle Dryer for High-Moisture Sludge
Handles sludge above 80% initial moisture
Hollow paddle agitators keep working the material without seizing, even on sludge too wet for conveyor-fed equipment.
Vacuum operation cuts energy per ton
Lower boiling point under vacuum means less heat input is needed to evaporate the same amount of water than at atmospheric pressure.
Built-in mixing breaks up clumps
Continuous agitation prevents the sludge from forming hard clumps as it dries, keeping output consistent for downstream handling.

Vacuum Rake Dryer for Continuous Sludge Throughput
Rake agitator keeps material moving
Continuous raking through the jacketed chamber exposes every part of the sludge to heat evenly, avoiding cold spots and uneven drying.
Odor-reducing vacuum operation
Reduced pressure limits volatilization of the compounds that cause sludge-drying odor, an advantage for plants near sensitive neighbors.
Mild crushing sizes the output
Dried sludge exits at a particle size manageable for landfill disposal, incineration feed, or beneficial reuse.

Centrifugal Spray Dryer for Liquid Sludge Streams
Suited to thinner, pumpable sludge
For sludge streams that haven't been mechanically dewatered, high-speed atomization converts the liquid directly to powder.
150°C–500°C inlet range
A wide temperature window lets you match drying intensity to whatever heat source — waste heat or dedicated burner — your plant has available.
Seconds-scale drying limits odor generation
Fast evaporation reduces the time sludge spends at elevated temperature, limiting the volatile compounds that generate odor.

Vacuum Drum Scraper Dryer for Thick Sludge Cake
Thin-film drying for viscous cake
Handles sludge too thick to pump through a spray nozzle by spreading it as a film on a heated rotating drum.
Continuous scraper discharge
A scraper blade continuously removes dried material from the drum, keeping the process running without manual clearing.
Flake output eases transport
Dried sludge exits in flake form — denser and easier to transport or landfill than loose powder.
