It’s not always an either/or, a lot of processes have both. If you have products that your process uses a splitting-type material, absolutely you should take advantage of that coalescer or that skimming process, that will help. It won’t necessarily separate those emulsified materials, but it’s going to be a big step towards improving and extending that process. If you haven’t made the investment in that ultrafiltration type of system, that would take care of both. It depends on what your mix is. If it’s 90% water-soluble coolants that might make since, but if its only 10% absolutely use the coalescer skimmer approach.
