If you need to remove oil

from water. YOU need Fram

I

Fram‘s oily water systems can remove oil down t o 5 ppm in 7 concentrations from 0 t o 100%oil/ 7 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 lnduslrial Division Trace Oil Analysis Kit designed for BOX 50096 TULSA OKLAHOMA 741% rapid on-the-spot readout of oil content in water.

changes induced by inorganic and organic pollutants, intestinal pathogens as pollutants, pollution and community ecology, microbial parameters of pollution, and microbiological approaches to pollution control. Compiled to promote understanding of the role of microorganisms in water pollution and water pollution control and to stimulate interest in microbial ecology of polluted waters among biologists and engineers.

Book is based on U S . patents since 1960 relating to hydrogen sulfide removal from gases and liquids. Supplies detailed technical information and can be used as a guide to the U S . patent literature in this field. Geothermal Overviews of the Western United States. approx. 192 pages.
