The Puraflo System is an advanced sustainable technology for the treatment of Wastewater in domestic homes.
Stage One: Primary Settlement – Physical Treatment
- The wastewater from the house flows into the existing septic tank.
- Initial settlement occurs.
- The gross solids sink to form a sludge layer at bottom of the tank.
- The liquid effluent flows by gravity into the pump chamber.
Stage Two: Puraflo Bio-filtration – Secondary Treatment
- The liquid effluent is pumped into the Puraflo modules.
- A pipework system at the top level in the modules evenly distributes the effluent onto a naturally occurring filter media.
- A combination of biological chemical and physical processes treat the effluent as it filters through the media in the modules.
- The treated effluent emerges from the modules through the outlet pipework for an approved disposal method.
