Submerged Fixed Film: Top 5 Considerations for Evaluating Different Systems
Submerged fixed-film systems are ideal for significantly increasing nitrification in existing wastewater treatment plants. A well-designed and operated system can double the nitrification capacity of an existing aeration basin. When choosing media for fixed-film applications, typical options include small, floating biomass carriers (moving bed systems) or structured-sheet PVC modules fixed in ...

Nitrification of municipal effluents in fluidised bed reactors using immobilised microorganisms
1. The problem Existing municipal effluent treatment plants designed earlier for the BOD removal are usually not suitable for nitrification at low temperatures, because of : Small plant dimensions and low sludge age, respectively Biokinetical reasons. Consequences are that in the cases of nitrification expensive plant extensions are required. 2. Our problem solution results in Plants ...

Airlift bioreactors: Application to wastewater treatment
After an introductory review, this paper presents a three-phase reactor fluid dynamic model that is used in the development of a generic process for upgrading existing wastewater treatment plants (WWT). The aim is to incorporate nitrification and de-nitrification without additional reactor volume. The core of the process consists of an attached growth airlift reactor (AGAR) in which a biomass ...

Pulp & Paper Mill’s #1 ASB Lagoon cleanout goes directly into Geotube containers - Case Study
Abstract: Integrated pulp & paper mill with an aerated stabilization basin built in 1969 was so full of solids that the mill was having several problems: degradation of treatment performance, inability to access aerators for maintenance, safety concerns, high energy usage, severe short circuiting. The decision was made that #1 Lagoon must be cleaned out. Evaluation of all types of removal, ...
