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.
Stages of water treatment:
The unit comprises of 3 chambers, each with an independent role in the treatment of wastewater.
- Stage 1 takes place in the primary settlement chamber where the wastewater is introduced. The solids drop to the bottom and are separated frin the liquid. Anaerobic breakdown now begins to occur and improves the water quality.
- Stage 2 takes place place in the aeration chamber, where masses of naturally occurring bacteria inhabit specially designed filter media. These bacteria are sustained with air which is continuously supplied from a purpose built pump in the top section of the unit. As the liquid flows through the filter media the bacteria feed on the impurities, consuming them, thus removing them from the liquid
- The liquid now flows from the aeration chamber into the final settlement chamber. Small quantities of bacteria known as sludge are carried with the liquid. The sludge settles towards the bottom of the final settlement chamber, where a continuous sludge return pumps back to chamber 1 The remaining treated liquid now meets the required standard to be safely passed to the percolation area.
