Wastewater treatment and water reuse is a strategic market of the group Alsys

In fact, wastewater treatment and water reuse is a strategic market of the group Alsys.

The availability of water and the efficient management of resources is becoming more impactful in both the municipal and industrial sectors.

In this field, key technologies and expertise of Alsys are domestic and industrial sewage BioReactor and Membrane.


Do you know what the optimal Mixed Liquor Suspended Solids (MLSS) concentration is for your Membrane BioReactor (MBR) system?

How high of a MLSS concentration can you go?

Here is a great article that provides a concise review (7 min read) of MLSS concentration and impacts. https://lnkd.in/e96XZ7T


It is a good reminder of key potential impacts:

  • Channel clogging
  • Sludge volume
  • Foulant concentration as related to solids
  • Oxygen Transfer efficiency and resulting aeration energy
  • On-site sludge processing ability vs. haul away


What is really interesting is the relation drawn to membrane thickeners and its operating characteristics, particularly shear rate from air scour versus sludge viscosity, that leave you wondering what the ceiling on MLSS concentration is.
