Nitrification and denitrification processes allow nitrogen-based compounds to be removed from the sludge in the wastewater treatment.
The use of suitable vertical agitators, during this phase, allows settling of the sludge present in the treated fluid to be avoided. Unlike in submerged mixers, with this solution there are no “dead zones” inside the tank and it requires no maintenance whatsoever. Our agitators are maintenance-free and are not subject to sudden failures.
Our 3PM-0134 and 3PM-0030 impellers are specifically designed to perform this function: they allow agitation of considerable volumes of sludge, even up to 1500 m3 with a single agitator, with a homogeneous and uniform mixing action through the entire volume.
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.
Three-blade impeller with high hydrodynamic profile. It is the “evolution” of Hurricane. Its internal velocity gradient, constant from the centre to the edge of the blade, allows the positioning of an impeller with large diameter very close to the bottom of the tank. That makes Evolution perfect for applications that require the mixer’s continuous operation during the total draw-off of the tank.
It can be manufactured with different diameters, 1650 to 3500 mm.
A completely disassemblable option is available as well, to ease the entering through the tank manhole.
