3 pcs. Archimedean hydrodynamic screw rotors manufactured for a wastewater treatment plant for renovation over a period of 2 year. This is the classical applaction for the Archimedes screw rotor invented by Archimedes in the Ancient time. The screw auger is designed to lift water from in-take of the treatment plant to the level where the cleaning process begins.

Why using an Archimedes screw rotor for waste water?

1. The hydrodynamic screw rotor has only one moving part
2. It can lift a large amount of water
3. It is not sensitive to foreign elements like tree branches, sand and other parts going out with sludge water

Other applications for Archimedes screw rotors:

1. Hydro power plants
2. Lock installations
3. Installation where you want to lift large amount of water in a fast and easy way

In this project BEMA has delivered the screw rotor to a cooperation company which renovated the complete installation. BEMA has assisted in measuring the old screw rotor and manufactured the replacment Archimedes screw rotors together with different wear parts.

Depending on the actual situation, BEMA can undertake different tasks of the whole renovation project. See similar example of this type of project.
