In the activated sludge process, the share of filamentous bacteria is crucial for proper settlement and high sewage treatment efficiency. Disequilibrium of the microbial community may be a reason for the appearance of bulking episodes. During 19 months (August 2007-February 2009) activated sludge samples were collected and analyzed by physicochemical, microscopic, and molecular methods. Amplifi...

Stress urinary incontinence (SUI) affects a large proportion of middle-aged and elderly women. When all conservative means are ineffective, a surgical treatment including retropubic suspension, pubovaginal and tension-free slings, is contemplated. Intra-urethral injections with bulking agents have been used as an alternative to the mentioned surgical procedures with alternate results. Many uret...

Bulking therapy for the minimally invasive treatment of stress urinary incontinence (SUI) may be offered to women with urodynamic SUI, wishing to avoid the complications associated with more invasive surgery, on the basis of low operative morbidity and low longterm success rates. These bulking agents may be injected by a retrograde or antegrade technique in the periurethral tissue around the bl...

Though potentially useful, agricultural byproducts are often discarded because of the lack of specific applications in many industries. However, they have suitable properties for use in the paper industry, according to recent literature. In this study, the suitability of rice husk, peanut husk, and garlic stem as raw materials for the manufacture of a new lignocellulosic bulking agent was inves...

Filamentous bulking and foaming are the most common settling problems experienced in activated sludge (AS) wastewater treatment plants (WWTPs). The quality of final effluent is poor during episodes foaming, which an environmental, human health economic burden. Remedial measures often ineffective, traditional non-specific methods such as chlorination may also negatively impact important function...

INTRODUCTION To evaluate the efficacy and durability of Urolastic, a new urethral bulking agent in women with stress urinary incontinence (SUI), after a follow-up of 24-months. MATERIAL AND METHODS A follow-up study of women with SUI who received a Urolastic injection and successfully passed the 12-month follow-up. Assessment included the Stamey Grade, 1-h Pad weight test, and the Internation...

The feasibility of vermicomposting technology to stabilize the distillery industry sludge mixed with a bulking agent (cow dung) in different proportions viz. 20% (T1), 40% (T2), 60% (T3) and 80% (T4), was tested using composting earthworm Perionyx excavatus for 90 days. The vermitreated sludge was evaluated for different physico-chemical parameters and all vermibeds expressed a significant decr...

1. The breakdown and faecal bulking capacity of dietary fibre preparations from wheat bran, apple, cabbage, carrot, and guar gum were compared in man and rat. 2. The degradation of the fibre showed good correlation between man and rat (r 0.99, regression coefficient 0.86). Wheat bran was the least well-digested, 66 and 59% of the neutral sugars being excreted in faeces of man and rat respective...
