Treatment Requirements
•Minimum of Title 22
Tertiary Treatment
•Evaluate need for added
levels of treatment
Treatment Requirements
Sequencing Batch Reactor
•Proven Technology
•Larger Footprint
•Potentially less costly in
smaller sizes ‐<2 mgd
Treatment Requirements
Membrane Biological
Reactor
•Proven Technology
•Smaller Footprint
•Modular – allows for
ease of expansion
•Excellent preliminary
step for advanced
treatment processes
