A water treatment unit (100) has a support housing (20) vertically extending between a support housing upper end (21) and a support housing lower end (22). The support housing (20) comprises a pair of opposing primary housing walls (30) and a pair of opposing secondary housing walls (31). Each of the secondary housing walls (31 ) is formed separately to, and mechanically joined to, each of the primary housing walls (30). Each of the primary housing walls (30) is perforated to allow airflow in a first direction (A) laterally through a treatment cavity (23) defined by the housing walls (30, 31 ). A plurality of hangers (54) extend in the first direction (A) between the primary housing walls (30) and are supported by the support housing (20). The hangers (54) are mutually spaced between the secondary housing walls (31) across the treatment cavity (23). A plurality of biotreatment membranes (70) each carry a biomass culture and are draped over, and supported by, one of the hangers (54) to define two opposing membrane walls (71 ) each extending downwardly from the hanger (54). |
