"Open Profile" MBBR Chips

Moving Bed Bio-Reactor (MBBR) Chips

Watterson's MBBR technology utilizes submerged surface area to allow for bacteria attached in a biological process. It is suitable in removing Chemical Oxygen Demand (COD) in a wastewater treatment system and at the same time reducing the footprint of the Wastewater Treatment Plant itself. Besides than that, it is also more reliable in treating ammonia through Nitrification process.

Advantages of using MBBR in Nitrification Process (Ammonia Removal)

Beside the advantages for COD and BOD removal, MBBR is also applies for Nitrification process or Ammonia Removal Process. MBBR is the most cost effective solution as it uses bacteria to oxidize the ammonia content. However, there are growing concerns that normal MBBR Chips may clogged up after few months or years when used in these process but with Watterson's MBBR Chips, the "Open Profile" structure of the MBBR Chips provides unrestricted access of backwash water's frictional force to clean itself. The figure below show the relation of Ammonium Nitrogen Removal Rate (g/m2/d) towards the amount of Oxygen Concentration (mg O²/L)

The additional surface area provided by Watterson's MBBR Chips also helps in reducing footprint for any wastewater treatment plant. This can help reduce a lot of cost in build a huge plant and reduce land usage by reducing Aeration Tank volume in a wastewater treatment plant.
