  • The expanded Bed Biofilm reactor (EBBR) – an innovative Biofilm approach for tertiary nitrification

    ABSTRACT The expanded bed biofilm reactor (EBBR) was developed by Advanced Bioprocess Development Ltd. (ABD) to provide a compact tertiary nitrification process. In terms of performance, the EBBR can meet an NH3-N discharge of less than 1 mg/L at high volumetric loading rates (1.0 kg NH3-N/m3 expanded bed /day). This high rate results from a predominance of nitrifying bacteria immobilized as ...

  • Anaerobic Reactor Design Concepts for the Treatment of Domestic Wastewater

    Since the earlier anaerobic treatment systems, the design concepts were improved from classic reactors like septic tanks and anaerobic ponds, to modern high rate reactor configurations like anaerobic filters, UASB, EGSB, fixed film fluidized bed and expanded bed reactors, and others. In this paper, anaerobic reactors are evaluated considering the historical evolution and types of wastewaters. The ...

  • The role of solution chemistry in the stability and detachment of cohesive kaolinite particles

    The effect of solution chemistry on the behavior of kaolinite in three different situations was investigated: (1) the detachment of kaolinite from glass beads in a fluidized bed, (2) the erosion of kaolinite deposits in a laboratory flume and (3) the determination of the stress-strain rate relationship of concentrated suspensions in a rheometer. The experimental results from these three different ...

  • Fine particle capture in biomass boilers with recirculating gas cyclones: Theory and practice

    This paper addresses the theoretical development and experimental validation of optimized recirculating reverse-flow gas cyclones. The simulation of these systems is based on the predictive properties of a finite diffusivity model, modified to include partial recirculation of the cyclones' emissions. Experimental validation was obtained at laboratory and pilot scales at low temperatures (up to ...

  • Laboratory, pilot and industrial-scale validation of numerically optimized reverse-flow gas cyclones

    This paper addresses the experimental validation of the optimum design of reverse-flow gas-cyclones, obtained through the solution of a numerical non-linear optimization problem, viz. maximizing cyclone collection. The simulation model is based on the predictive properties of a finite diffusivity model, where the particles' turbulent dispersion coefficient is estimated through an empirical ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Tertiary Nitrification Process - Case Study

    Our nitrification process was originally developed for ammonia removal from activated sludge final effluent. However, it has since been applied to sludge liquor ("reject water", "centrate" or "filtrate") treatment. It is also suitable for nitrification of potable water sources (e.g. surface or ground water) prior to chlorination, to reduce the formation of chloramines. Ammonia removal down to 1 ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...
