Excerpt
  1. What pore size foam is best for filtering flocculated suspensions and what determines “best”? Best might be determined by solids holding capacity, ease of cleaning, or effluent turbidity.

  2. Does head loss through the foam increase linearly with the mass of accumulated coagulant? This would match results obtained with sand filters by several AguaClara researchers.

  3. How much collision potential is needed in the flocculator?

  4. Should the energy dissipation rate in the flocculator be high enough to ensure that flocs are small so that surface clogging (solids accumulation on top of the foam) doesn’t occur?

  5. Do we need to use more than one foam filter in series with different sizes of foam?
