Panta Rei Srl products

All Panta Rei wastewater treatment plants are equipped with AirTech D9 by Panta Rei. This is a type of special disk diffuser with an EPDM membrane coated with PTFE - Teflon. A winning combination with the advantages of both materials, a synergy which boosts overall process efficiency. Our constant research along with our daily experience, have allowed us to transform the classic diffusers into a state-of-the-art product with significant improvements, such as: longer life, better performance, higher chemical resistance and less biofouling. All these enhancements translate into unparalleled economic benefits for our customers.

Panta Rei’s disc filtration with Ultrascreen Technology is a high-performance system for tertiary filtration of wastewater, which exploits the principle of “dynamic tangential filtration”. The influent feeding the filtering discs enters parallel into the filter media, differently from what happens in other kind of filters, characterized by an orthogonal filtering system. In the dynamic tangential filtration, where the mesh is continuously rotating, the same particle cannot pass through the mesh at an oblique angle and is retained on the screen.

PolyPreDos by Panta Rei is a simple and efficient device, made of stainless steel AISI 304, designed to prepare liquid polyelectrolyte solutions having variable concentrations according to the process characteristics required. The polymer emulsion is pumped, by a special screw pump with variable flow, to a dedicated primary mixing system. Afterwards, the solution reaches inside the stainless steel tank, where an agitator mixes the emulsion properly. A second progressive cavity pump carries out the final product dosing.
