The other advantage of FCR compared to activated sludge treatment is that the FCR is placed in a pleasant aesthetic structure that is odorless and suitable for tropical climates with the appearance of botanical gardens.

The excess solids of the settling tank are sent to the digester. Microorganisms use organic matter at solids are converted into a by-product as methane and water. Digestion results in a 90% reduction in pathogens and production of wet soil-like materials called "biosolids" contain 95-97% water.
