German to English translations [PRO] Tech/Engineering - Engineering: Industrial / wastewater treatment
German term or phrase:Oberflächenräumer
From an Austrian text on a new type of wastewater treatment plant.
Nur durch Druckluft befördern Oberflächenräumer und Tiefräumer den Schlamm.
Explanation: To me, the surface of a liquid would be a little difficult to scrape; I think that skimmer has to be right here...and as it CAN only skim the surface, the word "suface" isn't needed either.

Explanation: According to Langenscheidt Technik, a Räumer is a scraper or sludge collector.
The system includes a bottom scraper, a surface scraper and a rotating scum pipe.
While the Z 2000 is used to remove sediments, the surface scum in a primary sedimentation tank is removed with the surface scraper. This is generally used in conjunction with a rotating scum pipe. The blade of the surface scraper placed in the water moves along the tank surface, drawing foreign material toward the rotating scum pipe.
