of Handling

for First Time

High Feed Rates

Until recently, acid separation resisted the dialysis process because the membranes used could not stand up to acid. Many industries found it necessary to invest in expensive neutralization equipment as well as other disposal and recovery systems. Introduction of a new synthetic rèsin, which is resistant to most acids, has reopened the door to a practical dialysis system for the separation of chemicals which are difficult to handle. Graver's Hi-Sep unit is an integrated system complete with head tank and flow regulators. It ha? an exclusive feed control and is designed for maximum velocity and high separation. Because the system is essentially gravity feed, there is no need for electric power except for pumping liquids to the head tank. Once started, the unit operates on a continuous basis and requires little supervision. The unit is adaptable to other chemicals separation by changing 114 A

For Tough Separation Problems...

(MenAOK Hi-eF Purifiers There are three basic reasons Why more Anderson Purifiers, Scrubbers, Mist Extractors and Separators are used to solve tough separation problems than any other make. First, they have no moving parts, filters or screens that wear out or demand replacements. Second, since they need no large areas for filtering or screening they are extremely compact. Third, you receive a performance guarantee with each unit.

When National-U.S. engineers are called in early enough, they are frequently able to apply an unusual solution to a particular problem, because of their wide range of experience over a broad spectrum of industry. And only National-U.S. can offer both conventional heat exchange equipment in a complete range of metals plus units built from assemblies of corrosion-resistant cast iron.
