Biological Filtration

Case Studies

TECHNICAL DOCUMENTATION

Ceralite-A has more usable surface area for biomass than any other granular product. It has more surface area in the > 1.0 micron range than granular activated carbon.

  • Ceralite-A’s extremely rough inert surface allows excellent attachment and robust filtration process that recover quickly post backwash by protecting some biology from removal.
  • Ceralite-A’s lower density reduces backwash rates as compared to anthracite.
  • Ceralite-A is typically less expensive than low UC anthracite.
  • The improved surface porosity allows for higher filter loading rates as compared to anthracite.
