A treatment system for liquid or liquid and solid effluent. The system is enclosed within a pipe, duct (10) or trench and comprises one or more sloping filter beds (12, 13, 14) with a population of effluent decomposing organisms such as earthworms and mothflies, and an overlying air space. The aqueous media effluent inlet (11) is located above the uppermost filter bed at an upper end and the solid waste input inlet (31), when included, is located downstream of the aqueous media inlet so that the aqueous media flows through and around the solid waste material. A filtrate outlet (28) is located downstream of the flow through the system and manual or conveyor means are provided for solids removal.
Système de traitement d'effluents liquides ou semi-liquides s'installant dans une canalisation (10) ou une tranchée et comportant un ou plusieurs lits filtrants en pente (12, 13, 14) contenant une population d'organismes décomposant les effluents tels que des vers de terre ou des psychodes, et surmontés d'un espace d'air. L'entrée de l'effluent aqueux (11) se situe au-dessus du lit filtrant le plus élevé, à l'extrémité amont, tandis que celle des déchets solides (31), si elle est prévue, se situe plus en aval de manière à ce que le flux aqueux traverse et contourne les déchets solides. Un filtre de sortie (28) est placé en aval du flux traversant le système et des moyens de transports manuels ou un convoyeur sont prévus pour l'extraction des solides.
