发明名称 Rising filtration waste water treatment cell with granular filter medium has overflow water fed through metal funnel on concrete feed pipe
摘要 <p>The treatment cell has a granular filter medium (4) for a rising flow of waste water fed through a funnel (22) on the upper end of a concrete pipe (6). The funnel is made from a pre-formed piece of metal with its diameter directly related to the maximum permitted flow rate for the filter medium.
