Diemme® Filtration Thickeners

Diemme® Filtration’s High Rate thickeners are an advanced product derived from our extensive experience in solid/liquid separation applications, such as mining, chemical, waste water and more, coupled with our technical research to continuously improve and optimize sedimentation in filtration plants.

Unique Selling Point

• Complete LAB & SITE testing (flocculants type and dosage selection, static and dynamic test, rheology test, sensitivity analysis),
• Mechanical design of drive heads,
• Structural design of engineered tanks aimed at weight reduction (static and dynamic F.E.M. analysis, seismic assessment),
• Instrumentation & Control aimed at process optimization and Opex OPEX reduction,
• Customized vendor list,
• Global after sales service.


Diemme® Filtration’s High Rate thickeners cover a wide range of productivity and compliment the performance of Diemme®’s filter-presses, from our smallest to the largest unit.
Thickeners are available in “Full-Span-Bridge-Supported” design or “Center-Column-Supported” design (above 40m diameter). Furthermore, according to specific requirements of the project, tanks are available in “Free-Standing steel tank” design or “On-Ground concrete tank” design.

The process performance of a thickener is mainly defined by the way the equipment is able to mix the flocculant and solids particles, dissipate the energy and evenly distribute the slurry into the tank.
These functions are achievable with use of Diemme® Filtration’s feedwell, available with auto/forced dilution, designed with CFD simulations and validated in real operating conditions with outstanding performance in term of cost and operation. 
The results are low flocculant consumption, remarkable overflow clarity and consistent underflow density.
In particular challenging applications, Diemme® Filtration’s High Rate thickeners can be also equipped with cutting-edge technologies such as the Vector® feedwell manufactured by Diemme® Filtration under license from Paterson & Cooke.
