One type of biological water treatment is called MBBR (Moving-bed biological reactor). The so-called moving-bed consists of numerous growth carriers (growth bodies) within the treatment reactor, which have a high surface-to-volume ratio. The required quantity of growth bodies can be determined from the permissible surface load of 0.004 kg BOD/m²/day which is based on the inlet flow rate and organic loading. Example: 300 L/day greywater system for a single-family home As stated previously the average BOD concentration in greywater is on average 187.5 mg/L.
