The video below provides an introduction to the product and how it can be used.
After gaining a solid reputation in the United States for the past years, the Advanced Enviro-Septic pipe, distributed by Chankar Environmental, became available to the Asia-Pacific region in 2010. Because of its versatility, the Advanced Enviro-Septic pipe can be used in many configurations.
The Advanced Enviro-Septic pipe is a patented product made from 4 components:
- A cylinder-shaped pipe, made out of high-density polyethylene, with a corrugated design proven to increase the surface of thermal exchange. The pipe is also perforated to let the effluent out. Each of the wall ridges is topped with oblique notches, creating a unique airflow system essential to the propagation of the bacteria responsible for the treatment of wastewater.
- The Bio-accelerator allows for a fast ramp-up time.
- An non-braided polypropylene fiber membrane covers the pipe and facilitates the oxygen supply while supporting the biomass.
- A non-woven, polypropylene geotextile canvas, sewn around the fibrous membrane, keeps the earth particles from migrating into the pipe.
The pipes have a 30 centimeters (12′) diameter and are 3 meters (10′) long. The interior volume can receive up to 220 liters (58 gal US) of wastewater. All Advanced Enviro-Septic pipes are clearly identified with the brand name.
Couplings are used to link the pipes together. Special adaptors link up the piping for both water and air supply. No special tools are required to perform the installation.
As the effluent enters the Advanced Enviro-Septic pipe, it is cooled down to ground temperature. The ridges and oblique notches facilitate the process while providing an increased surface for thermal exchange when compared to classic systems. The system acts in a way that could resemble that of an underground radiator.
The cooling down then promotes the separation of fats and suspended material. The lighter solid particles float up to the surface as scum and the heavier ones sink to the bottom of the pipe to form sludge. These solids are held inside the pipe to prevent the clogging of the reception surface of the soil.
The effluent then leaves the pipe through its perforations. They then work their way through the fiber membrane where bacteria has settled to treat an additional amount of suspended solids. The fiber membrane is conditioned by the variation of the liquid level inside the pipe, caused by the peak periods of water use.
This aerobic/anaerobic conditioning promotes the propagation of bacteria responsible for the treatment process. This process is similar to the rotting of a wood picket fence. The rotting always starts at ground level where the humidity level change daily and where the bacteria is most active.
The effluent then moves through the geotextile membrane, where another layer of bacteria is formed on the inner surface.
By capillary action, the geotextile membrane and the surrounding sand gather and distribute the effluents on the pipe circumference, which then facilitates the evacuation of water into the ground. This process can be compared to an oil lamp wick which automatically fuels the lighted tip.
The treatment continues as the effluent seeps through the filtering sand surrounding the Advanced Enviro-Septic pipe.
When the water finally reaches the soil, it is almost completely free of contaminants. It then infiltrates the soil much more easily as it is evacuated into the environment.
