  • Influence of nanoparticles on the polymer-conditioned dewatering of wastewater sludges

    The effect of using small-scale, high surface area, nanoparticles to supplement polymer-conditioned wastewater sludge dewatering was investigated. Aerobically digested sludge and waste activated sludge sourced from the Hunter Valley, NSW, Australia, were tested with titanium dioxide nanoparticles. The sludge samples were dosed with the nanoparticles in an attempt to adsorb a component of the ...

  • Impact of Polymer Type and Dose on the Fate and Survival of Fecal Coliform during Centrifuge Dewatering

    Recent studies reported significant increases in indicator bacteria counts in anaerobically digested sludge samples during and shortly after centrifugal dewatering. The reasons behind the observed increases are not yet well-understood. This study investigated the effect of centrifuge shear and polymer addition on the fecal coliform counts measured after centrifugation. Centrifuge shear and ...

  • Chitosan use in chemical conditioning for dewatering municipal-activated sludge

    This work aims to evaluate the potential use of chitosan as an eco-friendly flocculant in chemical conditioning of municipal-activated sludge. Chitosan effectiveness was compared with synthetic cationic polyelectrolyte Sedipur CF802 (Sed CF802) and ferric chloride (FeCl3). In this context, raw sludge samples from Beni-Messous wastewater treatment plant (WWTP) were tested. The classic jar test ...

  • Accuracy and Cost Savings from Automatic Optimization of Dewatering

    Improvements in sensor and automation technology in recent years have made it possible to design a system to control the key variable parameters in and around the dewatering process. By continuously analyzing feed conditions and output from the process, an automated optimization system can make necessary proactive adjustments to the internal settings of the dewatering equipment, the polymer ...

  • Dewatering project in Almeirim (Portugal) - case study

    TenCate Geosynthetics has supplied TenCate Geotube® containers for a dewatering project in Almeirim (Portugal), which involves the removal and dewatering of organic sludge. This first project in Portugal is the result of cooperation between TenCate Geosynthetics, Ashland Hercules Water Technologies and Geosin, the local partner. TenCate Geosynthetics and Ashland Hercules Water Technologies ...

  • Wastewater-Solids Dewatering Odor Control - Case Study

    Background The Milan Wastewater Treatment Plant, located just south of Moline, Illinois, is a 1.7 MGD (6,434 m3/day) activated sludge facility with an average wastewater flow of 700,000 gpd to 800,000 gpd. This facility dewaters primary sludge using a belt filter press (Figure 1). The press operates an average of three times per month, 8 hours per day at a pump rate of 100 gpm. The ...

  • 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 ...

  • Effect of Secondary Aerobic Digestion on Properties of Anaerobic Digested Biosolids

    ABSTRACTIn this study, the performance of sequential anaerobic-aerobic digestion was compared to conventional anaerobic digestion for sludge from the Blue Plains Advanced Wastewater Treatment Plant. Volatile solids removal, polymer conditioning demand for dewatering, and biosolids odor characteristics following anaerobic digestion and sequential anaerobic-aerobic digestion were monitored. Aerobic ...
