Abstract
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).
Claims20
A wastewater treatment system, comprising:
- a cavity delimited by at least one wall and configured to receive a flow of wastewater for treatment;
- and
- one or more core sheets arranged within the cavity in a position to be contacted by wastewater entering the cavity, each core sheet having an outer surface, wherein
- the core sheets have a primary surface texture comprising surface irregularities on substantially the entire outer surface,
- the core sheets have secondary structure different from the primary surface texture, and
- the secondary structure takes the form of one or more cuspations.
A method for treating wastewater, comprising the steps of:
- providing a cavity delimited by one or more walls;
- assembling one or more core sheets within the cavity in a substantially upright configuration;
- directing wastewater into the cavity and into contact with the one or more core sheets, wherein
- the one or more core sheets have an outer surface,
- the core sheets have a primary surface texture comprising surface irregularities on substantially the entire outer surface,
- the core sheets have secondary structure different from the primary surface texture, and
- the secondary structure takes the form of one or more cuspations.
A wastewater treatment installation, comprising:
- a subsoil excavation;
- a wastewater treatment unit positioned within the subsoil excavation, the wastewater treatment unit comprising one or more core sheets having a primary surface texture comprising surface irregularities on substantially the entire outer surface and secondary structure different from the primary surface texture, wherein
- the secondary structure takes the form of one or more cuspations.
