The Contech Water Polisher is an advanced stormwater treatment system utilizing an
up-flow media filter with built-in pretreatment. This patented design features dual-chambered separation to remove large to fine sediments from stormwater runoff.
The up-flow filter assembly is constructed for superior durability and longevity, and is
a favored solution among civil engineers, municipalities, and developers for its ease of
maintenance and integrated internal bypass.
As water enters the system, head pressure builds behind the internal weir where sediment settles and driving head is created. Water then passes under the weir into the up-flow filter chamber. As water rises, it is forced through the media filtration bed for primary treatment before exiting the system.
During peak flows, the internal weir allows water to bypass treatment eliminating the need for an external bypass or junction structure.
