Advantages of Cricket Filters

Cricket filters have the design advantages of both pressure leaf filters and candle filters combined without having their drawbacks. These filters operate in a vertical pressure vessel with filter medium covering internal filtrate flow pipes, offering both dry and wet cake discharge.

Cricket filters are often used as a dynamic thickener or as a polishing filter after pressure leaf or vacuum filters.

Why Use CPE Cricket Filters

  • Higher filtration velocities
  • Lower sluicing volume per unit of filtration area
  • Large filtration area in small tank volume – due to shape and positioning of filter elements
  • High liquid throughput without filter cake erosion – up to 10 m3/m2h
  • High filtrate clarity
  • Filter media with low micron rating (optional) – clear filtrate from the start
  • Short regeneration times
  • Fully automated
  • Normally no pre-coating needed

Key Features of CPE Cricket Filters

  • Elements on internal filtrate manifolds: separate flow control possible, thus cake discharge for manifolds individually or in groups
  • Filter elements: Small internal volume, thus cake release with minimum backwash liquid
  • Internal filtrate pipe rising from bottom, thus no solids deposited in the filter element
  • Intensive cleaning of filter medium is possible (normally before filtration): Blow back, Backwashing
  • Precoat filtration: Secure fine filtration efficiency, prevents filter media from clogging
