The process is typically operated at MLSS in the range of 8,000–12,000 mg/L, while CAS are operated in the range of 2,000–3,000 mg/L. The elevated biomass concentration in the MBR process allows for very effective removal of both soluble and particulate biodegradable materials at higher loading rates.
Utilízanse SSLM para tratar entre 8.000–12.000 mg/L, mentres que os lodos activos se usan entre 2.000–3.000 mg/L. A elevada concentración de biomasa no proceso con biorreactores de membrana permite unha retirada moi efectiva dos materiais biodegradables solubles e particulados con grandes cargas de material.
