Roto-Sieve number 5000 delivered by Roto-Sieve France

A special project

Some projects are just that tiny bit more important than others. Early summer Roto-Sieve France delivered 2 Roto-Sieve model 24 at the communal WWTP of Pollestres in the south of France, located in the Eastern Pyrenees departement, near the city of Perpignan. This communal wastewater treatment plant serves approximately 10.000 population equivalents. The Kubota membranes were to be replaced after 10 years of service. Although the Roto-Sieves have a expected lifetime of more than 20 years (and far beyond in real life), they were replaced as well, because of local regulations. In September 2020 both Roto-Sieves were put into service.

Application: membrane protection in wastewater treatment plants

In this application, the Roto-Sieves are used to protect the sensitive Kubota membranes, by screening out as much as possible in the mechanical pretreatment stage. The Roto-Sieve drum screens are separating approximatively 10 tons of screening material per year. This way, they have a significant influence on the expected life time of the Kubota membranes.


Läckeby/Roto-Sieve is proud of the renewed confidence of the customer (we are talking about the replacement of existing Roto-Sieve drum screens) and very pleased that we were allowed to deliver Läckeby Roto-Sieve number 5000 and 5001 for this purpose. 

PS! The picture above was taken just before the installation of Roto-Sieve 5001.

Another milestone in the success story of the Läckeby Roto-Sieve has been realized! Roto-Sieve was the first patented water treatment rotating drum screen on the market and remains the reference drum screen. Roto-Sieve was a swedish invention and has become a standard in a vast majority of scandinavian wastewater treatment plants.
