Abstract
Treatment of wastewater containing contaminants is provided. More specifically, treating wastewater through capture and recirculation of percolated fluid effluent through and from one or more infiltration field systems is provided.
Claims19
A water treatment system comprising:
- a leaching conduit configured for receiving and distributing wastewater previously impacted by human activity;
- a treatment media, the treatment media receiving wastewater from the leaching conduit, the treatment media having a permeability allowing the received wastewater to be able to move through the treatment media, the treatment media formed as a below-grade leach bed layer positioned below the leaching conduit, the treatment media configured for treatment and percolation of the received wastewater;
- a region of increased permeability receiving wastewater from the treatment media, the region of increased permeability having a permeability higher than the permeability of the treatment media;
- and
- an impermeable layer within at least a portion of the region of increased permeability,
- where the impermeable layer is shaped to capture and collect all or a portion of the wastewater from the leaching conduit, and
- where the impermeable layer is shaped to allow wastewater from the leaching conduit to collect in and then overflow the impermeable layer and flow into an underlying region for further percolation.
4 more elements
A water treatment system comprising:
- a treatment train followed by a leaching system for water previously impacted by human activity;
- an underlying layer of soil, sand or natural permeable treatment media or man-made media below the leaching system;
- and
- an underlying region, below the leaching system and comprising a first permeable layer above an impermeable layer and a second permeable layer below the impermeable layer, the first and second permeable layers in fluid communication with each other;
- wherein
- the impermeable layer is configured to catch and recirculate a portion of water previously percolated through the underlying layer to the treatment train upstream of the leaching system and is configured to discharge for infiltration the remaining unrecirculated caught water.
