Graf 3750LT Septic Tank
Floating and removable material is extracted from domestic wastewater in mechanical septic tanks. This is pure mechanical cleaning, for which you need 500 l of capacity per inhabitant. If you assume a volume of 150 l, the wastewater passes through the system in 3 days. These septic tanks must have a total volume of at least 2,000 l. A 2,000 l system is sufficient for 4 inhabitants, another 500 l, must be incorporated for each additional inhabitant.
