Home sewerage treatment plants provide multi-chamber tanks to separate waste and undertake different treatment processes. They also contain media within the chambers as a surface for bacteria to grow on and breakdown the waste matter. Aeration is applied through an air pump which invigorates aerobic bacteria activity. A septic tank only relies on anaerobic bacteria to breakdown waste and the settlement of solids is the main process leaving water leaving the system putrid and full of contaminants and bacteria. Output quality from the Fuji Clean home sewerage treatment plants is far better than septic water and this allows the Home STP’s water to be used for irrigation.
