Lowest operating cost High on-stream time, often runs for years without shutdown for any reason Low maintenance: usually less than 1% of the capital cost per year High thermal efficiency Lowest horsepower demand of any continuous dryer Easy start-up (usually 1-2 days) Smallest footprint Accurate scale up Precise temperature control Cooling section on the bottom available Outdoor or indoor installation

TURBO-DRYER® Dryer Results

OBJECTIVE:A wastewater treatment facility located in QuebecCanada must meet tough standards for sludgedrying and land application.

Safe, odorless operation

Reliable production of dry sludge from27% dry solids to above 92% dry solids

Meet Canadian criteria for agricultural landspreading, 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 toachieve 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 andexplosion 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 thewastewater 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 airdelivery manifold system with baffles that further prevented hotinlet air from coming into direct contact with the sludge on thedrying trays.

The TURBO fans delivered a uniformly distributed and controlledlower temperature hot air mixture across the sludge material andacross the entire vertical structure of the TURBO-DRYER® dryer’sinternals.

Also as a result of the above noted design features, our dryers deliver a precisely controlled & uniformtemperature 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 specializingin 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.
