AquaMB Process®

Multiple Barrier Membrane System


The AquaMB Process® is a multiple barrier system that integrates biological treatment and clarification with dual barrier filtration consisting of cloth media and external membrane separation. It is ideal for wastewater plants that require optimum performance and flexibility at the lowest cost of ownership. Compared to multiple unit processes and membrane bioreactor (MBRs), the AquaMB Process offers numerous advantages with the added benefit of single source responsibility



How It Works


AquaMB® Process Diagram

Biological System
Flow enters the bioreactor where a series of independent phases promote biological treatment. Separate mixing and aeration devices allow the contents of the reactor to undergo biomass conditioning and nutrient reduction by alternating aerobic and anoxic periods. Following quiescent settling, supernatant from the reactor is transferred from the first barrier to the cloth media filter.


Cloth Media Filtration
Inlet water passes through the cloth media or second barrier. Filtered water is collected in the center tube where it is directed to a supply channel that feeds the external microfiltration membrane system.


Membranes
The membrane system is the final barrier of the AquaMB Process®. Feed flow enters the membrane module where low positive pressure enables the fluid to permeate the membrane, excluding fine particulates down to 0.02 microns in size. Filtrate from the membranes is directed to final discharge or reuse application.
