Sand Filters:

  • We provide Sand Filters to suit various flow rates.Sand filters will remove organic matter and solids from the water, but by acting as biofilters they also convert soluble nutrients back into organic matter in the form of bacteria cell biomass, which is then discharged back into the water supply.
  • Rapid gravity and pressure sand filters behave as biofilters, but the high water flow rates and backwash regime results in an unstable system
