  • Coagulant mixing revisited: theory and practice

    Are rapid-mixing tanks with intense mixing necessary? Intense mixing applies to the coagulation mechanism of charge-neutralization of negatively-charged particles, but this is not a common coagulation method. More common is precipitation of aluminum or iron for coagulation of particles and natural organic matter, which is often called sweep-floc coagulation. Coagulation by precipitation is ...

  • Adaptive control of algae detachment in regulated canal networks

    Open-channel distribution networks are subject to algal developments that can induce major disturbances such as clogging of hydraulic devices (pipes, weirs, filters, flow meters). Flushes can be used as a strategy to manage these algae developments. A flush is carried out by increasing the hydraulic shear conditions using hydraulic control structures of the canal network. In response to the ...

  • Fires at Composting Facilities: Causes and Conditions

    The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting facilities. Most are neither frequent nor destructive ...
