aerobic process. Since the biomass required is less, the nutrient concentration
required is very less. After a shutdown period, when nutrients are added the plant
operation starts quickly. The process generates slurry and a fibrous fertilizer. The
process is versatile for treating different types of wastes and is eco-friendly. The
process generates methane, which can be used as biofuel. Moreover, the process is
not energy intensive. The major disadvantage of anaerobic treatment process is that
it is not capable of removing inorganic pollutants which are present in the waste and
