The unit, having a preferable volume of 3 - 10 cu m, consists of a chamber (1, 2, 3) made from concrete and set below ground level. It has a top (4) with a manhole (5) and cover (6), and a number of holders (16) for aerobic bacteria that can be introduced through the manhole and moved to the required position inside the chamber. The unit, having a preferable volume of 3 - 10 cu m, consists of a chamber (1, 2, 3) made from concrete and set below ground level. It has a top (4) with a manhole (5) and cover (6), and a number of holders (16) for aerobic bacteria that can be introduced through the manhole and moved to the required position inside the chamber. Once inside the chamber the aerobic bacteria holders are positioned between vertical walls, where they are accessible to oxygen from an aerator with a tube (17) and membrane (18) located between the holders and the bottom of the chamber. The holders are made from a material with a density of less than 1, and they are kept below the level of the manhole cover by a separator.
