TL;DR: In this paper, a microsensor for O2 and N2O was used to study denitrification in a trickling filter biofilm where the reduction of the denitification intermediate N 2O was inhibited with acetylene.

TL;DR: In this paper, a new concept in liquid processing particularly in sewage treatment utilizing air, oxygen or a carrier fluid with some liquid or gas disinfectant as an attenuator or anaerobic biota, for generalized disinfection, for aeration, or for oxygenation is presented.
Abstract: The invention represents a new concept in liquid processing particularly in sewage treatment utilizing air, oxygen or a carrier fluid with some liquid or gas disinfectant as an attenuator or anaerobic biota, for generalized disinfection, for aeration, or for oxygenation Essentially, unique designs and/or processes are incorporated into the conventional settling tanks associated with sewage treatment, as well as in the bioprocesses, activated sludge or trickling filter operations The structural improvements in settling reduce velocity, inhibit boundary layer separation and act to suppress mixing of the sewage to greatly enhance solid and fluid separation, while the bioprocessing operations, the key is to improve efficiency of the liquid-gas exchange whereby much better oxygen contact is achieved The liquid-gas exchange feature utilizes a high momentum exchange under turbulent flow conditions in a hydraulic pressure gradient to achieve intimate mixing of the desired gas in the fluid so as to achieve the desired very reliably and efficient liquid-gas exchange

TL;DR: In this article, the effect of simultaneous removal of organic matter on the zero-order biofilm nitrification rate was discussed in relation to the production of faecal organic matter and its 24-hour fluctuation.

TL;DR: In this paper, the authors evaluated the biodegradation efficacy of a dispersed diesel fuel under high salinity conditions using an aerobic, upflow submerged biofilter coupled with a trickling filter, which is used to capture and treat volatile organic compounds (VOCs) escaped from the biofilter caused by aeration.
