English term or phrase:Log removal
A mathematical unit of representation on water cleanliness before and after filtering.
The logarithm (base 10) of the ratio of Influent particle counts over the Effluent particle counts.
Explanation: I am not 100% sure, but it looks as if they're talking about the reduction of the pH-value in the water.
See this explanation:
Der pH-Wert (von lat. potencia Hydrogenii) ist ein Maß für die Konzentration der Wasserstoffionen und zeigt damit die Stärke einer Säure oder Lauge an. Er wird als negativer Logarithmus zur Basis 10 der Wasserstoffionen-Konzentration angegeben.
"log removal" seems to me as if they want to get this value towards 0. Maybe the website below helps too.
