Fram’s oily water systems can remove oil down t o 5 m m in 7 concentrations from O t o 100%oil/ water. The three-stage Fram system plus a plate separator removes most oils, breaks emulsions which cannot be separated by other techniques. Where desirable, your Fram system can be automated for unattended operation. A strip chart records continued analysis, and signals when effluent exceeds pre-determined level. Special controls can be added t o evacuate oil accumulation, and a dual system can maintain continuous service when backwash is required t o keep element clean. When inquiring about a new Fram oily water system for your specific application, ask about our Corporation I Induma/ Division Trace Oil Analysis Kit designed for BOX 50096, TULSA, OKLAHOMA 74150 rapid on-the-spot readout of oil content in water.
