EPT - Expanded Granular Sludge Bed Reactor (EGSB)

The Expanded Granular Sludge Bed (EGSB) reactor is an anaerobic treatment technology where space constraints exist. The reactor is design tall and slender with a special internal configuration. The high pressure reactor can save the biogas holder or the biogas compressor, i.e. reduction in the capital and maintenance costs. This technology can be very highly loaded with 25-30 kg COD per m3 per day, compared to others anaerobic technologies (UASB and biobulk for example).
