Disadvantages        

High contact time and high effluent quality (both BOD and nutrients) High process stability, resistant to shock hydraulic or organic loading Short contact periods are required because of the large active surface Low space requirement Well drainable excess sludge collected in clarifier Process is relatively silent compared to dosing pumps for aeration No risk of channeling Low sludge production

Disadvantages      

Continuous electricity supply required (but uses less energy than trickling filters or activated sludge processes for comparable degradation rates) Contact media not available at local market High investment as well as operation and maintenance costs Must be protected against sunlight, wind and rain (especially against freezing in cold climates) Odor problems may occur Requires permanent skilled technical labour for operation and maintenance...
