  1. you can also use Hidrostal  type screw impeller submersibe pumps, this have massive solids clearance > 150mm 

  2. Normally, the MBBR media is removed from the tanks via the air-lifting solution.

  3. We have used a super vac and built a large temporary crib with carpentry and tarps and a drainage trough to extract and then clean the media for diffuser maintenance and air line repair on a Large WSB system in Ontario. It was a challenging and expensive job and real consideration needs to be given to this maintenance cost and procedure when designing an MBBR for onsite systems. 

  4. We also use a vac truck - make sure you have a place to dump it on the ground or into a container where you can control the drainage - the media can hold a lot of water and slime.

  5. You can use a super sucker to remove the media (centrifuge pumps are not advisable...)

  6. Have a redundant system so you can remove the MBBR membrane as it always gives polution in the chamber
