Partial nitrification to nitrite has been frequently obtained at high temperatures, but has
proved difficult to achieve at low temperatures when treating low strength domestic …

A granular airlift reactor enriched in ammonia oxidizing bacteria (AOB) was operated at 10°
C performing stable partial nitritation in the long-term. The reactor treated a synthetic low …

Abstract Recently, acidic (ie pH< 5) nitrification in activated-sludge is attracting attention
because it enables stable nitritation (NH 4+→ NO 2−), and enhances sludge reduction and …

A respirometry technique can be applied as an effective method to determine the net
maximum specific growth rate of autotrophic biomass under both normal conditions and …

Aerobic denitrification bacteria are currently being explored as promising microorganisms
with which to treat wastewater containing concentrated ammonium and organic carbon at …

The paper outlines results of the experimental assessment of nitrification kinetics applicable
to tannery wastewaters and the inhibitory effects of selected pollutants on nitrification. The …

Background This study evaluated the essential role of the experimental support as an
integral component of process design for the nitrogen removal activated sludge process …

This paper evaluates model-based upgrading of an activated sludge plant treating
wastewaters of leather tanning industrial district with an average capacity of 13,000 m3/d …

All models used in activated sludge design and analysis use parameters to characterize
process performance. The values of these parameters are often assumed based on default …

The process of nitrate/nitrite-dependent anaerobic methane oxidation (n-DAMO) coupled
with anaerobic ammonium oxidation (Anammox) is one of groundbreaking discoveries for …
