Types of anaerobic digesters: CSTR, UASB, plug-flow and hybrid configurations

There is no universal digester: the right configuration depends on the substrate, the scale and the objective. CSTR reactors (fully mixed) are the standard for agro-industrial and livestock waste; UASB reactors treat industrial wastewater at high speed; plug-flow reactors suit very solid substrates; covered lagoons are the low-cost, high-volume option; two-stage configurations separate phases for […]
