Oily Seawater separator - Material?
Oily Seawater separator - Material?
(OP)
We need to build a wastewater unit for separating oily water genereted by a naval test establishment. Water is heavily contaminated with solids, cleaning chemicals, emulsied oil and synthetic seawater.
From the collection tank, the wastewater will be treated through an ultrafiltration unit. The temperature during treatment might vary between 2-60 C. Depending on the location, piping will vary between 25-150 mm (1-6").
What material is best suited for this application? Plastic is not an option.
Thanks in advance.

However, what's wrong with carbon steel - painted or unpainted? This is what's typically used for OWS shells on marine vessels. If you're concerned about corrosion, you can paint the inside with a chemical resistant edge-retentive epoxy such as Sigma Edgeguard of Sherwin-Williams Novaplate.
