Common Technologies used in package sewage treatment plants are:
1. Primary settling + Anoxic stage (optional) + activated sludge process (forced aeration ASP) + secondary settling + filtration + UV/Chlorine. Ofcourse there is the option of SBR (Sequence Batch Reactors) or separate aeration and settling tanks. These systems require blowers and/or pumps for aeration and sludge recirculation and periodic removal of excess sludge by licensed contractor.
2. MBR based systems (may require CIP skid)
3. RBC (Rotating Biological Contactors) based systems (ex Biodisk Canada)
4. Electricity free installations (Biorock)
5. Advanced Oxidation Processes as polishing step (UV + Ozone + Peroxide)
6. Septic tanks
7. NEREDA (for larger installations) uses the Granular Aerated Sludge process as an SBR system
8. Trickling Biological Filter based STP's
Typical Effluent characteristics/removal efficiency (listed for Biorock):
BOD5: 98.7 % (4 mg/l)
COD: 96.3 % (26 mg/l)
SS: 99.3 % (3 mg/l)
