摘要： 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.

摘要： A wastewater treatment system includes a cavity configured to receive a flow of wastewater for treatment. One or more core sheets are arranged within the cavity in a position to be contacted by wastewater entering the cavity. The core sheet has a 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. One or more sheets of fabric may be used with the core sheet. The cavity may be within an aerobic treatment unit (ATU).

摘要： Leaching chamber units have an elongated body with a length extending between a closed end and an open end. The closed end of the leaching chamber unit may define one or more fluid flow openings. The elongated body of the leaching chamber unit has an arcuate, arched or convex cross-sectional shape and includes strengthening ribs extending transverse to the length of the elongated body. The strengthening ribs are arranged in a regular, repeating pattern along the length of the elongated body. The repeating pattern and complementary shape of the strengthening ribs allow the disclosed leaching chamber units to be nested for storage and transport. The disclosed leaching chamber units can be mated with each other at a range of longitudinal positions to form leaching chamber assemblies of a desired interior volume and leaching capacity
