i am unable to hold oneself back flush to the water's edge, see clear see low water has a few small fish in the swim.
我迫不及待的沖到水边,看见清澈见低的河水里有着几条小鱼在游来游去。
the automatic cleaning function can be realized by the back flush system, so that the cost for frequently replacing the filter element is saved, and the maintenance is simple and easy.
反向沖洗系统,可以实现自动清洗功能,节约了频繁更换滤芯的成本,维护简易。
the bottom of the biological aerated filter is equipped with the raw water intake and back flush module, and the process gas module is arranged above the raw water intake and back flush module.
在生物曝气滤池底部装有原水进水和反沖洗模块,在原水进水和反沖水模块上方装有工艺气模块。
increasing the back flush frequency reduces the irreversible membrane resistance increment, slows down the flux decline and improves the velocity of net water production greatly.
