Textured core sheets for fluid drainage unit
A core sheet includes a primary textured surface and separate secondary cuspations or corrugations. The core sheets are configured for use within a fluid or wastewater treatment unit that typically includes one or more fabric layers. The primary textured surface enhances retention of wastewater fluid received by the unit, which over time causes an increase in build-up of biomatter on the surface, which in turn enhances the efficacy of treatment of the wastewater. An inline process of making the core sheet includes extrusion forming a smooth flat sheet from raw polymeric material and immediately feeding the smooth flat sheet through texturizing rollers, followed by rolling flat textured sheets. Cuspations are added to the flat textured sheets, optionally at a different site, and then cut to preferred dimensions for incorporation into a wastewater unit.
