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.
