  1. Sewage Processing Plants – The particle size distribution and particle charge properties of solids in the final settling tanksInternational Environmental TechnologyVol. 11 Issue 6 Nov/Dec 2001Wolfgang Schubert, F. Wolfgang Gunthert, Renate Hessemann …The theoretical sedimentation time of a 1-micron particle is around 210 days; for a 10-micron particle it is 50 hours; and for a 100-micron particle 30 minutes. Therefore in the final settling tanks, particles smaller than 100-micron that have sedimentation times of several hours may not settle-out completely…

  2. Figures 1 and 2 show, as an example, the measured particle size distribution (from 6 to 3000-micron) in the final settling tanks of an activated sludge process and from a fixed bed plant respectively… * Area Distribution representative of total particle size spectrum

  3. “Selective Separation”

  4. Baleen – the “missing link” 10,000 1000 100 10 1.0 0.1 0.01 0.001 Primary Secondary Tertiary Coarse Screening Fine Screening Baleen Filtration Micro filtration Ultra filtration NanoFiltration ReverseOsmosis

  5. The Baleen filter…

  6. Modular design…

  7. Baleen’s flow handling capability (kL/hr) within Municipal applications… The above tabulated performance figures refer to separation of visible, settle-able matter* *Subject to site survey

  8. Baleen (inline micro-screening) Vs Settling (clarifier retention) Objective: Separation of visible constituents from storm water influent Outcome: Baleen offers “absolute” retention to a given micron-rating * Includes minimum working clearance **Includes minimum civil clearance (1.3x)
