How Clarity Biofilters work

The latest filtering technology...


Environmentally friendly, reliable and more compact than a conventional septic tank design, Clarity Biofilters use the latest filtering technology to clean and dispose of onsite wastewater.


Wastewater from the house flows into the biofilter septic system where all the solids settle on the bottom and organic matter begins breaking down.


The remaining diluted organic material is then processed over the media where naturally occurring bacteria break it down further. A UV disinfection system disinfects the wastewater as it leaves the biofilter.


At this point the wastewater has been cleaned to a standard that exceeds those required by Service NL. The wastewater then flows into a diffuser which disperses it into the soil.


Clarity Biofilters require minimal maintenance because the system is so efficient. The tank only needs to be emptied approximately every two to four years or as necessary. However, we do recommend that you get the system serviced annually to ensure optimum performance. Please see our servicing page for more details.

Biofilter Media


Clarity Aquatech

The plastic media inside Clarity Biofilters is designed to have the largest possible surface area. This means there is more opportunity for microorganisms (bacteria, fungi, yeast etc), macroorganisms (protozoa, worms, insect lavae etc) and extracellular polymeric substances (EPS) to develop inside the system and form the biofilm where the treatment occurs.


Biological filters are more robust than other filtration methods, despite their superficial structures, due to the varied biology and ecology of the microorganisms in the biofilm, which allow the systems to adapt to different conditions (e.g. varying levels of use.) This means you can relax knowing that your system will not let you down.


And like our biofilters, Clarity biofilter media is designed to last a lifetime so you don't have to worry about replacing it.
