  • 5 Reasons to Use Eductor Systems for Complex Rehabilitation

    Rehabilitation of dams and levees present complex geotechnical conditions. Contractors require dry, safe and stable working environments in order to carry out an effective rehabilitation project. As our national dam and levee infrastructure ages, the pressure to stabilize construction sites and lower costs will rise. Eductor systems provide a safe, cost-effective dewatering solution for these ...

  • Dewatering optimization with in-line and real-time measurement of polymer: results from full-scale treatment plants

    Full-scale testing was carried out at two wastewater treatment plants to determine whether residual polymer concentration, measured by filtrate and centrate absorbance at 191 nm, can be used to identify the optimum polymer dose and achieve in-line and real-time dewatering optimization. The first plant uses high speed centrifuges and the second plant uses belt filter presses for dewatering. ...

  • The Importance of Dewatering

    With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game.  Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control ...

  • Flocculating and dewatering performance of hydrophobic and hydrophilic solids using a thermal-sensitive copolymer

    Thermal-sensitive polymers have been tested on settling, compacting or dewatering of clays or oil sand tailings. However, not much attention has been paid to explore the effect of temperature on flocculating performance using thermal-sensitive polymers. In this study, poly(NIPAM-co-DMAPMA) was synthesized and employed to investigate the flocculating and re-flocculating performance of ...

  • The intermediate thermal hydrolysis process: results from pilot testing and techno-economic assessment

    Thermal hydrolysis has proven to be an efficient pre-treatment process for sludge before anaerobic digestion (AD), by thermally enhancing organic matter hydrolysis. Recent research has shown that a new configuration with the existing technology can further enhance the efficiency of the system. The intermediate thermal hydrolysis process (ITHP) has been explored and tested in the Sludge and ...
