ABSTRACT:
The present invention comprises a trickle filter media which maximizes wastewater contact with both sides of the media sheet. The media comprises a corrugated sheet, where the corrugations run vertically. Within the valley of each corrugation is a protuberance which effectively blocks off the cross-sectional area of the valley, to falling liquid. The protuberance is rounded such that once the liquid contacts the sheet, surface tension will cause it to remain in contact with the sheet until it reaches the bottom end of the sheet. The protuberance is extended from each side of the sheet to block off alternating valleys on opposite sides of the corrugated sheet. For structural stability, these protuberances are staggered vertically along the sheet and include reinforcing ribs.
