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. The cell also has a rapid-opening valve (18) for discharging flushing water into an adjacent tank (10), the valve being fitted with a brush to clean a fine-mesh grille next to the outlet (9).</p> |
