Tri-Cel® Bio Systems
The tri-cel P6 bio system is a single unit that treats wastewater for premises housing up to 6 persons.
The system is manufactured from GRP and is approved by the Agrément bord and relevant authorities.
The gravity flow system is suitable for most sites. However, if your site is sloped or require a raised
bed percolation area, a pumped system may be required to pump the treated water into the percolation trenches.
We offer a free site assessment and can advise on what system would be suitable for your site.
Alarm
An alarm may be fitted to the treatment system to alert the homeowner to a failure within the system.
The alarm will alert the homeowner by sound and a visual light on the fuse board. Once the problem is
rectified the alarm will automatically re-set. The alarm is always supplied with a pumped system.
The alarm detects the following:
- Air pressure failure to the system
- Air compressor (blower failure)
- High water level detection
- Float switch failure
- Pump failure in a pumped system
- Overload protection for the Tri-cel in the fuse board
- Short circuit protection for the Tri-cel, in your home
Manhole Riser
Manhole Risers are used to extend the height of the manhole to ground level, should there be a need for
deeper installation of the tri-cel. They are available in 250mm, 500mm and 750mm increments.
Distribution Box
Distribution boxes are used the divide the flow of treated water into the percolation trenches. We supply
a 7-hole distribution box, which may be blocked off with caps if you wish to reduce the number of flows
into the percolation area.
Stages of water treatment:
The unit comprises of 3 chambers, each with an independent role in the treatment of wastewater.
- The wastewater enters the primary chamber, whereby the solids drop to the bottom. Anaerobic breakdown now begins to occur.
- The liquid flows into the aeration chamber, through the filer media, where naturally occurring bacteria feed on the impurities. The bacteria are sustained by an air pump that is fitted in the top of the system.
- The treated liquid flows into the final settlement chamber. Small quantities of sludge are carried with the liquid, settle to the bottom and are returned to the primary chamber. The remaining treated liquid now meets the required standard to be passed to the percolation area.
