Need to separate polyelectrolyte from water in a pilot plant in continuous (or semi-continuous) mode.
Lab tests indicate separation at ~5500G is sufficient.
Inlet flow rate capacity of the unit can be anywhere from 0.5-5L/min.
Solids content in the inlet solution is ~0.5%
"Solid" phase will...
I need to apply an ultra-thin layer of aqueous solution evenly to the inside of a 2 meter long glass tube to form an optical coating (as the water evaporates, leaving the dissolved product deposited). I have had difficulty finding an economical system. Any suggestions?

Continuing from the thread above, does anyone have any advice on how to control a multi-stage membrane concentration system for continuous flow production?
I need the permeate + product flow to match the (moderately)...
Working on a budgetary estimate for a polyethylene polymerization plant,
Can anyone point me to some cost data on metallocene catalysts and more importantly on the aluminoxane.
The vendors seem to be reluctant to respond to my requests for budgetary pricing.
I also have to do a life-cycle...
I have a waste stream composed of:
Ethanol ~50% +/- 20% (denatured)
Water ~50% +/- 20%
NaCl ~1-3%
NO3 (nitrate) ~0-3%
organic compounds 1-3%
I would like to recover the (denatured) ethanol for reuse, and minimize the volume of other stuff to dispose of. (I can tolerate up to 30% water in...
