Influence of water treatment residuals on dewaterability of wastewater biosolids
Co-dewatering of water treatment residuals (WTR) and wastewater biosolids can potentially benefit municipalities by reducing processing equipment and costs. This study investigated dewaterability (using capillary suction time, CST) of combined alum residuals (Al-WTR) and anaerobically digested biosolids at various blending ratios (BR), defined as the mass ratio of WTR to biosolids on a dry ...

Comparison of centrifuge and belt press for compressible digested sludge after thermal hydrolysis
ABSTRACT Historically it has been shown on many projects that centrifuges can outperform belt presses in dewatering digested sludge. However results from a number of projects where sludge has been treated before digestion with Cambi thermal hydrolysis process (THP) have shown good results for belt press dewatering – generally greater than 30% DS. The authors propose that the main mechanism in ...

A pilot study of anaerobic membrane digesters for concurrent thickening and digestion of waste activated sludge (WAS)
The increased interest in biomass energy provides incentive for the development of efficient and high throughput digesters such as anaerobic membrane bioreactors (AnMBRs) to stabilize waste activated sludge (WAS). This paper presents the results of a pilot and short term filtration study that was conducted to assess the performance of AnMBRs when treating WAS at a 15 day hydraulic retention time ...

High Rate Treatment of CSO/SSO Flows Using a High Density Solids Contact Clarifier/Thickener - Results from a Pilot Study
ABSTRACT A two-month pilot study was conducted at the Village Creek Wastewater Treatment Plant in Birmingham, Alabama to test the technical feasibility of utilizing a high-rate, highdensity solids contact clarification process for the treatment of sanitary sewer overflow (SSO). Five phases of testing were performed over the two-month period. During Phase I testing, optimum steady state operating ...
