Mercer - Construction Materials
Mercer fabricates a standard line of above ground rectangular oil/water separators from marine-grade aluminum (#5052), epoxy-painted carbons steel, 304L stainless steel, and 316L stainless steel. We have also built units in polypropylene, PVC, and other exotic stainless steel materials such as Duplex to meet a particular corrosion requirement. Our cylindrical below ground units are fabricated from epoxy-painted carbon steel and have various FRP coatings available for additional corrosion protection. Mercer will work directly with the consultant and end user to pick preferred coatings for a specific application based on temperatures of wastewater, and the corrosive potential of an application.
Our standard Multi-Pack coalescer`s frame is built from 304L or 316L stainless steel. The coalescer plates will vary depending on the application`s requirement. Coalescer plate material choices include: #5052 aluminum, 304L stainless steel, 316L stainless steel, acrylic, and PVC. FRP epoxy resins composite plates are available for lightweight, high temperature, applications where corrosion resistance is essential.
Mercer can also supply passive cathodic protection for our separators, as needed. Strategic placement of magnesium or zinc anodes will help protect the separator from naturally-occurring electrical currents or the stray electrical currents in industrial facilities (such as found at electric power stations).
