Filamentous organism bulking in nutrient removal activated sludge systems
نویسنده
چکیده
A model is outlined for the major biochemical respiratory mechanisms of a conceptualised heterotrophic facultative organism (representing the heterotrophic facultative mass of activated sludge) subjected to four different sets of conditions: steady-state aerobic, steady-state anoxic, steady-state aerobic changed to anoxic, and steady-state anoxic/anaerobic changed to aerobic. Proposals and implications of the model regarding changes between these conditions are tested experimentally and verified with special aerobic batch tests on sludges from IAND, 2RND, MUCT, continuous aerobic, and continuous anoxic systems fed municipal sewage.

Bulking control with chlorination in a nutrient removal activated sludge system*
This paper deals with control of bulking by chlorination in a laboratory-scale (15l/ d) biological nutrient removal system. Bulking was caused by filamentous organisms characteristic of nutrient removal systems, i.e. Type 0092, Microthrix parvicella and Type 0914. Over a continuous dosing period of 19 d, at 8 mgCl2 /gMLSS.d the diluted sludge volume index (DSVI) decreased from 230 to 48 ml/g. N...
متن کاملBulking control with ozonation in a nutrient removal activated sludge system
The control of sludge bulking by ozonation was studied on four parallel pilot-scale (110 l/d) biological nutrient removal systems. Bulking was caused by filamentous organisms which typically occur in nutrient removal systems, i.e. Type 0092, Type 0041 and Microthrix parvicella. Continuous dosing of ozone, at 1; 2 and 4 g O3 /kg mixed liquor suspended solids (MLSS).d resulted in a diluted sludge...
متن کامل"Microthrix parvicella", a filamentous bacterium causing bulking and foaming in activated sludge systems: a review of current knowledge.
This review summarizes the microbiology and physiology of "Microthrix parvicella" and the methods of its growth control in activated sludge wastewater treatment plants. This filamentous bacterium is of high interest because of its worldwide involvement in severe bulking and foaming at wastewater treatment plants. We present a critical analysis of physiological and kinetic data on "M. parvicella...
متن کاملRepetitive extragenic palindromic PCR (REP-PCR) as an alternative method for detection of bulking in activated sludge.
Bulking of activated sludge is a world-wide problem which negatively affects wastewater treatment efficiency. The most common reasons of bulking are bacterial community changes, especially excessive growth of filamentous bacteria (filamentous bulking) or excess of biopolymers on the surface of non-filamentous microbes (non-filamentous or Zoogleal bulking). Because of the complex nature of the b...
متن کاملPrediction of Filamentous Sludge Bulking using a State-based Gaussian Processes Regression Model
Activated sludge process has been widely adopted to remove pollutants in wastewater treatment plants (WWTPs). However, stable operation of activated sludge process is often compromised by the occurrence of filamentous bulking. The aim of this study is to build a proper model for timely diagnosis and prediction of filamentous sludge bulking in an activated sludge process. This study developed a ...
