TURBO-DRYER® Dryer Results
OBJECTIVE:
A wastewater treatment facility located in Quebec
Canada must meet tough standards for sludge
drying and land application.
Safe, odorless operation
Reliable production of dry sludge from
27% dry solids to above 92% dry solids
Meet Canadian criteria for agricultural land
spreading, that also conforms to US EPA
Class A bio-solids processing
DUSTLESS, and ODORLESS OPERATION & END PRODUCT
TEST RESULTS
The TURBO-DRYER® Dryer unit achieved the dryness & temperature requirements in order to
achieve a Class A Criteria.
Safety and processing targets were met while maintaining a clean operating environment.
The unit delivered:
A dust free environment – a key characteristic of both a safety and a hygienic workplace.
A granular and odor free product (In contrast, dusty dried product poses ignition and
explosion hazards)
No detectable odors observed during dryer operation
LABORATORY TEST METHOD:
Based on results of laboratory tests performed on wet product samples, the TURBO-DRYER® dryer installed at the
wastewater facility demonstrated highly successful performance.

Unit – L24 TURBO-DRYER® Dryer
Unit Dimensions: 6’ Diameter x 12’ Height
Skid Mounted System
304 SS construction for all internal surfaces
Variable speeds for trays and TURBO-Fans
Multiple Screw Feeder
Dual External Heating System, electric and propane burner
Fresh air supply fan
Interconnecting ductwork with control dampers
Control panel with mounted controls and instrumentation
The unit was equipped with a specially-designed hot air
delivery manifold system with baffles that further prevented hot
inlet air from coming into direct contact with the sludge on the
drying trays.
The TURBO fans delivered a uniformly distributed and controlled
lower temperature hot air mixture across the sludge material and
across the entire vertical structure of the TURBO-DRYER® dryer’s
internals.
Also as a result of the above noted design features, our dryers deliver a precisely controlled & uniform
temperature drying atmosphere, consequently minimizing sludge overheating or baking.
The Wyssmont® dryer system operates under a mild vacuum.
Low odor characteristics of the dried sludge product were corroborated by a certified third-party lab specializing
in odor measurement testing.
Air Samples from 3 sources were taken from the following areas to determine Odor Unit Levels:
dried sludge product
ambient air in proximity to the dryer (out-loading area)
dryer exhaust.
