摘要： The present method provides a solution on problems in connection with nitrogen generation in or gas supply to a continuously operating granular filter in a biological process during processing water. The solution is that the biological process is carried out in the filter bed and that the filter medium (1) is transported from the bottom of the filter bed to the upper surface thereof, however with the essential difference that the filter medium (1) is not subjected to any washing in connection with this transport (2) and altogether not at all. The water from the transport is instead mixed with the water passed through and processed in the filter bed and are discharged together, eventually to a succeeding treatment step.

摘要： It is known to filter a suspension or emulsion in a filter bed of particulate filter medium (1) by allowing the suspension to flow upwards through the filter bed simultaneously as the medium (1) flows downwards through a filtering tank (2) wherein filtration takes place. Filtration thus takes place during counterflow between suspension and filter medium. The supply of suspension takes place in the lower part (4) of the filter bed and the filtered liquid phase is taken away from a zone (8) above the filter bed. The polluted filter medium close to the bottom of the filter tank is taken out for conveyance to a washing apparatus (13) above the filter bed and after washing is returned to the upper side of the filter bed. For providing a filter which has a considerably lower construction height than previously for a given and unchanged volume of the filter medium, the washing apparatus (13) is now lowered so that its lower part is at a level below the upper surface of the filter bed.
摘要翻译：已知的是，当介质（1）向下流过过滤槽（2）时，允许悬浮液同时向上流过滤床，将过滤介质（1）的过滤床中的悬浮液或乳液过滤，地点。因此，过滤在悬浮液和过滤介质之间的逆流过程中发生过滤。悬浮液的供应发生在过滤床的下部（4）中，过滤的液相从过滤床上方的区域（8）中取出。将过滤罐底部附近的污染过滤介质取出，输送到过滤床上方的洗涤装置（13），并且洗涤后返回到过滤床的上侧。为了提供一种过滤器，其具有比以前对于给定且不变的过滤介质体积的结构高度低得多的结构高度，洗涤装置（13）现在下降，使得其下部处于低于过滤床上表面的水平。
