Fast start-up of anammox process with hydrazine addition

Fast start-up anammox process using Acyl-homoserine lactones (AHLs) containing supernatant.

N-dodecanoyl homoserine lactone (C12-HSL) was detected in the supernatant of an anammox granular sludge reactor (AGSR). C12-HSL could enhance the specific anammox activity of anammox biomass. Adding C12-HSL-containing AGSR supernatant into the continuously stirred tank reactors reduced the start-up time of the anammox process from 80 to 66days. Moreover, the nitrogen loading rate was also enhan...

The Start-up of the Anammox Process in the Membrane-assisted Bioreactor

ABSTRACT The experiments carried out proved possibility for implementation of deamonification process in membrane-assisted bioreactor. At the temperature above 30°C, dissolved oxygen concentration below 0.8 mg O2/L and at the very low contents of biodegradable organic compounds within 1 month of process operation stable nitrite and ammonia nitrogen concentrations were reached at the levels resp...

Fast start-up, performance and microbial community in a pilot-scale anammox reactor seeded with exotic mature granules.

The possibility to introduce the exotic anammox sludge to seed the pilot-scale anammox granular reactor and its fast start-up for treating high nitrogen concentration wastewater were evaluated in this study. The reactor was started up successfully in two weeks; in addition, high nitrogen removal was achieved for a long period. Stoichiometry molar ratios of nitrite conversion and nitrate product...

Studying the process of transformation of the start-up to the academic spin off

At todaychr('39')s universities, we are witnessing the emergence of startup companies by the startup teams by student and academic teams; unfortunately, most startups face barriers to success. On the one hand, one of the new topics entering the fourth-generation universities and can be a good target for the future of the startups; the existence of academic spin-offs, centered around scholars...
