The fermentation process in a septic tank produces a mixture of odourous gasses that includes Methane. These gasses need to be safely vented to atmosphere, hence your ventilation pipe. Unfortunately, they are often badly sited and, as a result, Nasty Niffs can sometimes find there way to your patio or BBQ area. So the question is: "How can you get rid of the pong without affecting the proper operation of the vent pipe?
The STUDOR® MAXI-FILTRA™ is an Activated Carbon filter designed to eliminate bad odours produced by the drainage system. Easily fitted to your existing vent pipe, its replaceable filter cartridge allows the system to "breathe" but prevents the Sulphides that create the odours from reaching the atmosphere.
Although initially designed for use with septic tanks, the STUDOR® MAXI-FILTRA™ has been sucessfully installed in many other applications including: packaged treatment systems, holding tanks, basement lifting stations, pump chambers and drainage vent pipes.
It can now be found in many diverse locations including: residential properties, campsites, water treatment plants, schools, hospitals, hotels, power stations and even some of the World's biggest SuperYachts.
The activated carbon in the filter cartridge has been impregnated with chemicals that attract particular contaminates by a process known as "Adsorbtion". (no that's not a typo) When odour molecules come into contact with its surface they dissolve and become trapped i.e. Adsorbed. Meanwhile, other components of the sewer gas, such as Methane and Carbon Dioxide, are not adsorbed. The filter is, in effect, transparent to them and they can pass right through to be safely vented to atmosphere.
MAXI-FILTRA™ is fitted to the vent pipe that should be present on the output side of the septic tank (fosse-septique).
The locations of tank vent pipes vary. They are often routed underground, back to the house or to some other nearby object for support. When fitted with the filter, height becomes less important and the pipe may therefore be lowered to facilitate cartridge replacement.
