Gravity Filtration

Case Studies

TECHNICAL DOCUMENTATION

Ceralite-A is a low-cost alternative to anthracite that provides longer filter runs (higher UFRV’s) and lower clean head-loss than anthracite coal. The lower density improves backwash fluidization and can lower backwash rates.

  • Ceralite-A has lower clean loss and supports higher flow rates due to the lack of surface layer fines following a backwash.
  • The improved surface porosity allows for higher filter loading rates as compared to anthracite.
  • Ceralite-A’s lower density reduces backwash rates as compared to anthracite.
  • Ceralite-A is typically less expensive than low UC anthracite.
