Underdrain filter block
February 1, 2007
The Tetra Snap T underdrain filter block promotes stability of the block position during backwash procedures. Water, wastewater and industrial filtration facilities have an underdrain system to support filter media and to separate the filter media from the bottom of the filter. The underdrain system allows filtered water to pass through the collection system and start the distribution of backwash water and air.
