Wā: 2020-07-22 Hits: 80

MBR technology? Are you familiar with how to use it?



I nā makahiki i hala iho nei, ua hoʻohana nui ka kaʻina MBR e ka poʻe. Hiki i ke kaʻina MBR ke hoʻohana i loko o nā noi he nui e like me ke hoʻohana hou ʻana i ka wai i hoʻihoʻi ʻia, ka hoʻomaikaʻi ʻana i nā kūlana kūlohelohe, a me ka hānai ʻana i ka mālama kino. E like me kā mākou e ʻike ʻana, ʻo ke kumu nui o ke kaʻina MBR ka nui o nā hoʻohana ākea nui ma muli o kona mau maikaʻi e like me ke kaena kiʻekiʻe, ka lōʻihi o ka pālolo, lōʻihi ke hoʻopaʻa ʻia ʻana, a me nā wāwae liʻiliʻi.

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.


In the next article, we will continue to introduce the misunderstandings of the MBR process.
