  • 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 ...

  • 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 ...
