The PuraSAF Wastewater Treatment System provides a cost effective, low energy, pre-engineered Wastewater Treatment Solution that is simple to operate and maintain.
The filter media are produced from recycled plastic that provide an ideal medium for biological attached growth. The process uses the media to provide superior oxygen transfer rates providing a very low operating cost solution.
The filter normally operates in an upflow packed bed configuration that is readily fluidized for cleaning and desludging. In aerobic mode, the PuraSAF Wastewater Treatment System offers a small footprint, low headloss solution for BOD, and Nitrification, and in an unaerated mode as an anoxic stage for denitrification or as a low-cost tertiary solids filter that approaches sand filter quality.
The process can be designed for a number of Wastewater Treatment applications including as a secondary Wastewater Treatment unit, for tertiary Wastewater treatment reducing ammonia on existing works or lagoon effluent, as a temporary measure while an existing asset is being refurbished or replaced; as an emergency Wastewater Treatment stage on a failing works; to handle seasonal peak loads and in an unaerated mode as a low cost solids tertiary filter or as a denitrification filter.
The PuraSAF Wastewater Treatment System is available as a mobile rental or lease unit. The PuraSAF Wastewater Treatment System process can be installed as a pre-engineered package system or designed in concrete tanks.
