Macro‐invertebrate associations in sewage filter‐beds and their relationship to operational practice
1. The macro‐invertebrate faunas of 67 filter‐beds in 48 sewage works throughout Great Britain were surveyed in relation to the physico‐chemical characteristics of the bed environment. Faunal samples were collected from the surface medium and from the bed effluent. Fifty‐nine of the beds were sample...
