Mixers for wastewater

Get the mixing that best suits your wastewater system with a mixer or flow generator from Landia. We have solutions for large volumes of water, smaller tanks and for liquids with varying amounts of dry matter content.

Let us find a solution together 

The benefits of a submersible mixer for wastewater (low speed)

Landia POPL-I is a low-speed mixer or generator flowmaker. Its primary use is for mixing and creating flow in large volumes of water at an exceptionally low energy consumption. 
With the adjustable propeller blades, the energy consumption can be adjusted by changing the angle of the propeller blades. it may be possible to achieve an energy consumption that is less than 1 W/m3.

The propeller blades on a POPL-I Flowmaker are made of stainless steel. Experience shows that the propeller blades last forever, and you therefore get a lifetime warranty on propeller blades on your POPL-I mixer. If your wastewater is of an aggressive nature, POPL-I can even be supplied in acidproof stainless steel.

Flexible mixer for wastewater (medium speed)

Landia POP-I 180 is a flexible and efficient mixer. It is used for mixing and flow creation with a low energy consumption. It can be used, for example, in aeration tanks or anaerobic tank sections. Landia POP-I 360 is most often used for mixing liquids with a high dry matter content such as dewatered sludge. The relatively low speed and strong propeller design make the POP-I 360 the ideal mixer for all types of highly viscous liquids.

The Landia POP-I is also available in stainless steel, if needed.

The benefits of a submersible mixer for wastewater (compact)

Landia POD-I is a compact mixer that is typically used for mixing liquids with a relatively low dry matter content and in smaller tanks. The POD-I can be operated at liquid levels below 1 m. The propeller speed is 900, 1200 og 1800 rpm. If Landia POD-I is to be used for aggressive liquids, it is also available in stainless steel.
