sand-bed filter

The sand filtration system was built by a 10m length, 2m width, 2m depth flume with construction of brick and cement. The building was divided into eight sand filter beds, which were packed with three kinds of sands in a cube 1m long.

试验构建一个长约10m、宽2m、高2m的砖混结构渗滤池，渗滤池分隔为8个小渗滤池，选择3种不同的沙分别构建1m3见方的渗滤床。

The manganese removal ability of the sand-filter was closely related to the bacterial content of the filter layer.

结果表明，石英砂滤池除锰能力与砂层细菌含量密切相关；

We main manufacture: dredger , sand pumping vessel , sand filter , transporter, sand selecting equipment, conveyer belt, etc.

公司主要生产: 挖沙船、抽沙船 、 筛沙机 、 运输船 、 沙石精选设备 、 输送带、磁选机 、 等矿山机械设备.

The structure of the filter is optimized at last. The process includes the waste purification from oil emulsion in Tilted-Plate Separator and the suspension separation in the downward-flow sand-gravel filter.

处理方法包括使用倾斜盘式分离器分离油乳化剂，使用下流式砂砾过滤器分离悬浮颗粒物。

Metal sand filter pack is considerable parts in fiber production. It can reuse via recycle.

组件金属砂是长丝生产消耗品,通过对金属砂的回收,可是现金属砂的多次再使用.
