ʻEnehana MBR? Kamaʻāina ʻoe me ka pehea e hoʻohana ai?



I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ka hana MBR e ka poʻe. Hiki ke hoʻohana i ke kaʻina MBR i nā noi he nui e like me ka hoʻohana hou ʻana i ka wai i kiʻi hou ʻia, hoʻomaikaʻi o nā kūlana o ka nohona, a me ka mālama ʻana i ka wai hoʻoneʻe. E like me kā mākou āpau, ke kumu o ka MBR kaʻina hana he nui laha hoʻohana no ka mea, o kona poʻokela pono e like me kiʻekiʻe ukana, lōʻihi mud makahiki, kiʻekiʻe ka hoʻokōʻana o ka shutoff, a me ka liʻiliʻi footprint.


E hoʻomau kēia ʻatikala e hoʻolauna iā ʻoe i ke kuhi hewa e pili ana i ka hoʻohana ʻana o ka hana MBR i ka hoʻomaʻemaʻe wai wai.

 

Misunderstanding 4: In order not to block the membrane, reduce the sludge concentration as much as possible.

 

Correct interpretation: Blocking the membrane is a common problem in MBR applications. The membrane is usually blocked by sludge, especially when the sludge concentration is too high. Therefore, there is a misunderstanding of reducing the sludge concentration to avoid blocking the membrane.

 

This is precisely another misunderstanding. In fact, too low concentration and too high concentration of sludge will make the membrane quickly blocked. The correct approach is to keep the sludge concentration in a suitable range.

 

In addition, aeration has the effect of flushing the membrane surface. Therefore, the appropriate aeration amount should be maintained during the use of the MBR process.


Ma ka ʻatikala aʻe, e hoʻomau mākou e hoʻolauna i nā kuhi hewa ʻole o ka hana MBR.
