Inhibitory Effect of a Surfactant on Pure Cultures of a Filamentous and a Floc Forming Micro-Organism
(Taylor & Francis Ltd, 2007-02)
Activated sludge is the most widely used biological process for wastewater treatment. Inorganic and organic compounds are removed by a biotic community in the aeration basin. Problems of these systems are loss of settleability ...
Use of image analysis in the study of competition between filamentous and non-filamentous bacteria
(Pergamon-Elsevier Science Ltd, 2004-06)
One of the most common problems in the operation of activated sludge plants is the inability to separate solids from treated effluents in the clarifiers caused by the overgrowth of filamentous micro-organisms (FM) with respect ...
Modelling of chlorine effect on floc forming and filamentous micro-organisms of activated sludges
(Pergamon-Elsevier Science Ltd, 2003-03)
Activated sludge technology is more used than any other for biological treatment of wastewater. However, filamentous bulking is a very common problem in activatedslud ge plants, chlorine being the chemical agent normally ...
Parámetros fisicoquímicos asociados a la proliferación de bacterias filamentosas (Bulking filamentoso) en las plantas de tratamiento de aguas residuales mediante lodos activados: revisión sistemáticaBalcarcelPhysicochemical parameters associated with the proliferation of filamentous bacteria (filamentous bulking) in wastewater treatment plants using activated sludge: a systematic review.

Growth kinetics of the filamentous microorganism Sphaerotilus natans in a model system of a food industry wastewater
(Pergamon-Elsevier Science Ltd, 2000-12)
Bulking by Sphaerotilus natans has been attributed to several factors such as low dissolved oxygen in the aeration basin, wastes with high C:N ratios and phosphorus limitation; however, the occurrence of bulking has been ...
Effect of Ozone on Filamentous Bulking in a Laboratory Scale Activated Sludge Reactor Using Respirometry and INT-Dehydrogenase Activity
(American Society of Civil Engineers, 2006-09)
Filamentous bulking can be controlled by the addition of oxidant chemical agents such as ozone. To evaluate the ozone effect on activated sludge from a laboratory scale reactor, different techniques were applied: Settleability ...
Uso de talco no controle do intumescimento filamentoso no tratamento de efluentes de fábrica de papel recicladoUse of talc for filamentous bulking control in effluent treatment plant of a recycled paper mill
(Universidade Federal de ViçosaBRManejo Florestal; Meio Ambiente e Conservação da Natureza; Silvicultura; Tecnologia e Utilização deMestrado em Ciência FlorestalUFV, 2015)
Effectiveness of chlorination and ozonation methods on pure cultures of floc-forming micro-organisms and activated sludge: A comparative study
(Water Research Commission, 2007-12)
Chlorination is a very useful control method of filamentous bulking in activated sludge systems; however, it favours formation of undesirable compounds such as trihalomethanes. Other oxidants, such as ozone, could be used ...
Possible link between the power spectrum of interstellar filaments and the origin of the prestellar core mass function
(EDP Sciences, 2015)
A complete understanding of the origin of the prestellar core mass function (CMF) is crucial. Two major features of the prestellar CMF are 1) a broad peak below 1M(circle dot), presumably corresponding to a mean gravitational ...
