Sludge mixing

More than 40 years of experience providing solutions for mixing sludge in sewage treatment plants.

Efficient mixers for wastewater sludge

Reception, digestion and drainage of sludge play a vital role in a sewage treatment plant. The constant development of sludge drainage technologies places great demands on the mixers. Landia has a wide range of equipment for mixing wastewater sludge. Whether it is a septic sludge receiving tank containing large amounts of rags and debris, or a high viscosity polymer dewatered storage tank, we have the products to do the job. 
If the sludge causes bothersome odors, a combined mixing and aeration solution in the form of a Landia AirJet aspiration pump may be the solution. 
Landia has a wide range of different types and sizes of mixers and can therefore tailor the optimal mixing solution to your particular system.

The durability is almost legendary

Landia supplied the first mixers for sewage treatment plants in the 1980s. There are many Landia mixers at sewage treatment plants around the world who have passed the 25-year mark – some even 30. Now that’s true sustainability!
Frequent follow-up, testing and development has meant that we have kept up with the times and today can offer energy-efficient mixing combined with a lifetime beyond the usual – something we are of course willing to guarantee!

The Landia mixers have always worked well. This is the type of reliable equipment we want as ESD delivers improvements to Scotland’s water and wastewater infrastructure.

-  said St Andrews WWTP Site Manager, Alan Mearns.
