Improved septic tank with an upflow anaerobic filter

A septic tank consists on a pit that receives and treats the waste waters of a house or building. In this pit, solids get separated by a sedimentation process and the organic matter in the water gets stabilized through the so called “septic process” due to the action of anaerobic bacteria transforming it into a harmless sludge.

A grease trap or shredder must be provided to the system previous to the raw water entrance.

For the septic tank technique it is primal that the soil has enough infiltration capacity and not only the size of the tank.

In a septic tank the sludge is placed mainly in two sections: the heaviest get settled at the bottom of the tank and those containing greases, which are lighter, float above the previously mentioned layers.

Generally speaking, the anaerobic filters with upflow filters consist of three main sections:

Therefore the DP-TSM6 consists in four stages:

The septic tank – anaerobic filter combination requires a periodical maintenance, oriented mainly towards the removal of solids that get retained in the first unit and the washing of the second to prevent possible obstructions in the pores through which the waste water flows.
