Industrial waste water

Vertical agitators for wastewater treatment

In most industrial sectors, water is used in production processes: to ensure that these processes are successful, it is therefore necessary to adopt reliable solutions for mixing industrial wastewater.

This need is particularly pressing in chemical-physical plants, where the presence of a vertical agitator calibrated to the density and viscosity of the fluid is essential for the preparation of the reagents and their subsequent integration in the main process.

To make it easier to choose the most suitable solution for each customer in the field of mixing water and wastewater, PRO-DO-MIX® has also introduced an important tool: its proprietary A.P.P.L.E. software, a configurator that includes all the successful PRO-DO-MIX® technology and allows users to quickly and easily find the perfect agitator for any industrial needs.

    The very heart of every vertical agitator

    Thanks to our technical expertise as well as an in-depth knowledge of mechanics and fluid-dynamics, we have developed a complete range of impellers – made with stainless steel or other high-quality materials – in order to fulfil every mixing process.

    2PM-0650 PREMIUM

    Flocculation Mixer

    Flocculant mixing system with two-blade impeller. Thanks to its high hydrodynamic profile with wide blade surface, has the highest flow rate at the lowest peripheral speed. This design is aimed to prevent the fluid coming out from one blade to immediately meet the second blade.

    Therefore, it is perfect when managing very delicate applications, where the fluid needs to be handled very gently and carefully. That is why Premium is specific for flocculation.

    It can be manufactured with different diameters, 800 to 3000 mm.

    A completely disassemblable option is available as well, to ease the entering through the tank manhole.

    3PM-1084 EXCELLENT

    Industrial Mixing Impellers

    Three-blade impeller with high hydrodynamic profile. Within our industrial impeller models, it has the lowest torque for the same flow rate. Moreover, it can create the highest flow rate with the lowest peripheral speed.

    It is perfect as flow-maker, for high head values in recirculation.

    It can be manufactured with different diameters, 200 to 3500 mm.

    A completely disassemblable option is available as well, to ease the entering through the tank manhole.

    3PM-0134 HURRICANE

    Flash Mixing Impellers

    High-efficiency three-blade impeller with high hydrodynamic profile. Thanks to its high flow rate, it is particularly suitable for flash mixing, sludge and solid suspension, equalization, etc.

    It can be manufactured with different diameters, 900 to 1500 mm.

    A completely disassemblable option is available as well, to ease the entering through the tank manhole.
