moving bed biofilm reactor nitrogen removal

Introduction to Moving Bed Biofilm Reactor (MBBR)

The Moving Bed Biofilm Reactor (MBBR) is a top-notch wastewater treatment technology. It uses a biofilm formed on plastic particles to get rid of organic compounds and nutrients. The particles are in motion due to an aeration system. This stops clogging, plus it gives optimal oxygen transfer.

MBBR can be used as a single system or incorporated into existing wastewater treatment plants. Installation and operation is easy, so it’s ideal for both urban and rural areas. Plus, it has a high treatment capacity and can handle changing influent loads without losing efficiency.

A super cool feature of MBBR is its nitrogen removal. Bacteria use nitrification and denitrification to change ammonia to nitrate, then nitrate to nitrogen gas. So this process meets strict nutrient discharge regulations.

Pro Tip: Regularly check the biofilm thickness and use the proper carrier size to keep the MBBR system working properly. Nitrogen removal may not sound fun, but it’ll stop rivers from becoming mutant algae monsters.
