Septic tanks with partial biological processes
Septic tanks with partial biological processes are used to extract floating and removable substances. Due to the sizing of 1,500 l per inhabitant, the wastewater passes through the system in approx. 10 days. This allows the microorganisms that have emerged in the sludge to effect partial breakdown of the organic waste, in addition to pure mechanical purification (partial biological purification). These septic tanks require 1,500 l per inhabitant and must comprise at least 3 chambers.
