How do septic tanks work?

You need to change your sewage treatment system and you are wondering how do septic tank works? The septic tanks use different technologies to treat the sewage of your house.

To illustrate this, we will use the example of the Tricel Vento. The Tricel Vento is a sewage treatment product manufactured and sold by Tricel in Ireland and the United Kingdom. The Tricel Vento is a sewage treatment divided into two different chambers.

Three phases of treatment

The sewage from your home will go through these 3 phases, in order to be treated. All this before returning to the natural environment.

Phase 1: First of all, the water flows into chamber one and is diverted downwards with a T piece. The solids will drop to the bottom of the tank (and will become sludge after the first anaerobic breakdown).

Phase 2: Secondly, the lighter material and the liquid from sewage will flow into the second chamber. A layer of scum will be created at the top of the liquid water.

Phase 3: Finally, after the filtration of your sewage, these will go through the outlet filter to a final treatment in a specially designed percolation area. The percolation area will complete the treatment and allow your water to return, treated, in natural environments, without risk of environmental pollution.
