How many UF and NF stages/trains will you have?
If you have multiples, it is also possible to compensate for a stage/train being down by ramping the producing units to maintain a constant UF flow. Of course you will need to be a bit conservative on the UF design flux.
With this said, it is...
Your best bet is to contact one of the membrane suppliers as many of the operational issues are dependent upon the type and configuartion of the membrane.
In my opinion, the best product on the market currently is the PURON product of Koch Membrane Systems, Inc.

If this is a pilot system I would do both. Are you planning on performing pressure and flow excursion exercises as well? What UF tube are you planning on using?
Sounds like you plan on running in a batch configuration. What is the size of the process tank and what will be the membrane...
This really dependent upon the nature of the process. What specific process (MF, UF, NF, RO) and what is it that you would lile to process (water, wastewater, milk, juice, paint, caustic, acid, etc.)? Also, how are you intending to operate (feed & bleed, single pass, dead ended, batch...
SBush is correct UF can be used dependant upon the final product desired. RO is also used for milk concentration. See the attached web page.

What's is the polymer you are using? that will tell you if HC's will effect them. While HC's may or may not contribute to degradation, free oil's will foul the membrane. This will effect productivity.
How are you determining this maximum flow? Dependent upon the answer, it could be as simple as three lines of PLC logic. Based upon my exposure to CBI's claricone clarifier's build weir structures doesn't seem to be the answer. This would have to be accomplished through PI control using the...
MortenA is generally correct. Barite is used to increase solution densities as required. In addition the solvent used may not be water only. I believe you reach a limit of about 16-17 pounds per gallon with water based muds. I have seen oil based muds that run upwards of 20 pounds per...
Hollow fiber membranes are not the best chose when solids are involved. You run the risk of the solids becoming built up on the upstream side of the tube sheet as well as the probability of plugging the fibers. Again, this type of application is typically handled via tubular membranes.
If you...
What type and configuration of membrane are you planning to use? There are large channel tubular membranes that this would not be a problem with. The only possible issue with the tubular membrane is surface area of membrane relative to floor area of the system.
Take a look at...
