Functioning of the Enviro-Septic System
Treatment
process of the
Enviro-Septic
system
The rows of Advanced Enviro-Septic
®
pipes and system sand permit the
treatment and distribution of wastewater on the surface of the receiving soil
(surface of the polishing leaching field or the leaching bed).
The pipes support, first of all, the separation of particles through flotation and
decantation. The water is then evacuated through perforations situated all
around the pipes and through the pores of the three layers of synthetic media
covering the pipes. These membranes facilitate the fixation of the microbial
cultures which support wastewater treatment as well as longitudinal
distribution.
The layer of sand continues the treatment process and helps in dispersing the
water before it infiltrates into the natural soil. In this way, the Enviro-Septic
system integrates both functions of treatment and evacuation.
Diagram of the
Enviro-Septic
chain of
treatment
The chain of treatment varies according to the method of discharge used.
Figures 2.1 to 3.2 show the different options possible.
Underground evacuation
Figures 2.1 and 2.2 show the progress of the water along the complete chain
of treatment for a system using underground evacuation
