A continuous belt dryer platform engineered for U.S. WWTP sludge and biosolids — cutting hauling and land-application/disposal cost by shrinking volume 3–6×, and giving your plant a documented, Class A-capable output as PFAS-driven land-application limits tighten state by state.
Response within 24 hours · Serving U.S. municipal WWTPs, POTWs and their engineers · UL 508A · NFPA 79
A continuous belt dryer with independently controlled heating zones — sized to your solids content, throughput and end-use target, whichever stream it is.

Especially plants facing rising tipping fees, shrinking landfill capacity, or tighter land-application permit conditions.
Evaluating belt dryers for a primary/secondary sludge, digested biosolids, DAF, or water-treatment residuals stream of any size.
Different moisture profiles, different handling needs — the same engineering discipline behind each one.
High-moisture sludge from primary clarification, dried into a stable, low-odor material.
Activated-sludge biosolids from the secondary treatment stage, dried and stabilized for easier handling.
Anaerobically digested cake dried to a stable, pathogen-reduced, Class A-capable product.
High-fat, high-solids DAF float and industrial pretreatment sludge, dried without fouling your line.
Years of accumulated lagoon or storage-basin material, dried into manageable, haulable volume.
Drinking-water treatment residuals dried for lower-cost landfill disposal or beneficial reuse.
Every dryer is sized to your sludge or biosolids' feed solids content, moisture target and daily throughput. These are the ranges we engineer within:
| Belt width | 700 – 3,250 mm |
| Dryer length | 10 – 45 m |
| Output capacity | 200 – 2,000 kg/hr per line |
| Feed solids | 15 – 35% dry solids (sludge/biosolids) |
| Discharge moisture | 10 – 20%, to your end-use spec |
| Temperature control | ±1°C (PID, zone-logged) |
| Construction | Stainless / mild steel, corrosion-resistant or food-grade |
| Heat source | Gas · Steam · Waste heat · Electric · Thermic fluid |
| Trial available | Yes — on your own material |
If any of these sound familiar, drying changes your operations.
Landfill tipping fees and hauling costs for biosolids have climbed steadily across the country for two decades, with capacity shrinking near many metro areas.
EPA's 40 CFR Part 503 framework, its July 2026 draft PFOA/PFOS guidance, and 10+ state-level rules continue to narrow what utilities can do with land-applied biosolids.
On-site lagoons, storage basins, and shrinking land-application acreage consume valuable space and draw community and regulatory scrutiny.
Wet biosolids are heavy and bulky to move. Reducing moisture content cuts volume 3–6x, and haulage cost along with it.
Odor, runoff, and visible sludge stockpiles near plant sites increasingly draw attention from regulators and neighboring communities alike.
Most WWTPs already operate digesters and dewatering infrastructure that make drying a natural next step — not a ground-up capital project.
Said in plain language. No consultancy-speak.
Dryers built to run continuously, not seasonally.
Specs designed with the EPA Part 503 and PFAS guidance framework in mind.
Engineered for easy spares, predictable service — under 0.5% spares cost typical.
Repeatable moisture targets, batch after batch.
26+ years of design refinement built into every weld.
Pilot trial → right-sized capex → predictable running cost.

"No buy-and-fly." A retained engineering partnership backs every dryer long after commissioning — which is a big reason 88% of our clients come back for their next machine.
Because the dryer is IoT-connected, our engineers can read its live data and often diagnose — even resolve — an issue before a service truck ever rolls.
Critical spares stocked and dispatched fast worldwide. Historically under 0.5% of machine value per year — a total cost of ownership finance teams love.
Scheduled preventive maintenance and priority response keep uptime high and surprises low. We plan the service so your operators don't fight fires.
On-site installation, commissioning and hands-on operator training so your team runs the line confidently and safely from day one.
Process tweaks, capacity upgrades, new-stream trials — a long-term partnership, not a one-time transaction. We stay on the line with you.
Simple, rugged, low-part-count engineering means fewer things to fail — and clients running 4+ years of continuous operation with minimal maintenance.
Our belt dryers run in municipal and industrial sludge applications across 15+ countries. Ask us for current municipal references in your state as our U.S. installed base grows.
"Consolidated 3 dryers into 1 — with 5× the capacity. The footprint and energy savings changed the economics of our line."
"The installation and commissioning of the dryer for belt press sludge and centri-cleaner sludge were carried out seamlessly. The equipment demonstrated reliable operation and high-quality workmanship."
"4+ years of continuous operation with minimal maintenance. It simply runs — that's what we needed."
Send us your sludge profile and throughput. We'll size the right dryer, run a free lab trial, and show you the hauling, disposal-cost and Class A upside — usually within 24 hours.
