Control of sludge bulking in an SBR-plant treating slaughterhouse wastewater Linda Jonsson In December 2003 the new plant treating slaughterhouse wastewater from KLS was taken into operation. Läckeby Water Group was entrepreneur and responsible for the maintenance during the following two years. The treatment plant is of SBR-type and has biological nitrate removal and chemical precipitation of ...

Fecal incontinence (FI) is defined as the uncontrolled passage of feces or gas over at least 1-month duration in an individual of at least 4 years of age who had previously achieved control [1-4]. Incontinence has a negative impact on self-esteem and quality of life (QoL) and may result in significant secondary morbidity, disability, and cost [1]. Prevalence rates vary widely depending on the m...

Submucosal deposition of bulking agents is increasingly used for the treatment of intrinsic stress urinary incontinence both in male and female patients. Bulking agents should ideally be nonimmunogenic, biocompatible, non-migratory, injectable, cause a minimal inflammatory reaction, retain the submucosal bulging effect, and reasonably cheap. None of the agents available to date fully meets thes...

We investigated the dynamics of the microfauna community in activated sludge, with special reference to sludge bulking, in two parallel municipal wastewater treatment systems in Beijing, China over a period of 14 months. Annual cyclic changes in microfauna community structures occurred in both systems. RELATE analysis based on Spearman's Rank correlation indicated that microfauna community stru...

OBJECTIVE A patulous Eustachian tube ([ET] tuba aperta) may cause symptoms as autophony, breath synchronous tinnitus, pressure sensation, and conductive hearing loss and thus lead to an enormous cutback in quality of life. In combination with "sniffing," it can trigger the development of cholesteatoma. Because of the ambiguous symptoms, the diagnosis can be challenging. A patulous ET can only b...

PURPOSE Subureteral injection of bulking agents in the endoscopic treatment of vesicoureteral reflux is widely accepted therapy with high success rates. Although the grade of vesicoureteric reflux and experience of surgeon is the mainstay of this success, the characteristics of augmenting substances may have an effect particularly in the long term. In this retrospective study, we aimed to evalu...

The establishment of sustainable soil waste management practices implies minimizing their environmental losses associated with climate change (greenhouse gases: GHGs) and ecosystems acidification (ammonia: NH3 ). Although a number of management strategies for solid waste management have been investigated to quantify nitrogen (N) and carbon (C) losses in relation to varied environmental and oper...

Rather than landfilling, composting the organic fraction of municipal solid wastes recycles the waste as a safe and nutrient enriched soil amendment, reduces emissions of greenhouse gases and generates less leachate. The objective of this project was to investigate the composting effectiveness of three bulking agents, namely chopped wheat (Triticum) straw, chopped mature hay consisting of 80% t...

Purpose. We reviewed our 20 years of experience and the current literature regarding the long-term outcome of endoscopic treatment of vesicoureteric reflux (VUR) using the different tissue bulking substances with a special emphasis on the long-term efficacy. Material and Methods. Our own experience and the current literature on the long-term results after endoscopic treatment using various bulk...
