Epuration Individuelle) And How Does It Work - The Septic Tank ...
In the example shown below, compressed air (supplied from a compressor sited outside the tank) is used for aeration and effluent flow is due to gravity where sometimes one or more pumps are employed for aeration and movement of the effluent. Basically, the system consists of two chambers, one inside the other, where fine air bubbles are pumped though the secondary inner chamber to promote aerobic bacterial action. Its main difference is its use of natural biological aerobic (reliant on oxygen) action enhanced by pumping small air bubbles through the effluent. Until recently, all waste systems had to be paired with a sand filter bed but the French authorities are now beginning to approve certain sewage treatment units to be installed without a filter bed, draining either into a land drain or nearby... Unlike the limited waste treatment of a septic tank, the treatment plant is significantly more efficient. Small domestic sewage treatment plants are by far the most effective system of waste treatment. This type of system is known by many names, Biological Treatment Plant, Biodigester, Continuous Aeration Plant (CAP), Sequential Batch Reactor (SBR), to name but a few.
“You can stick [the WaterStick] into a septic tank and drink potable water out of it,” Gilder told Forbes. “You can actually change the filtration function that you want to perform in these nanotubes. There are tens of thousands of these devices going
