INSET: Ion exchange units and control panel at Mt. Tom Power Plant of Holyoke Water Power Company, Holyoke, Mass.
AMBERLITE® resins deionize organic-bearing water for high pressure boilers Here are the results AMBERLITE ion exchange resins are producing at the new Mt. Tom Power Plant of the Holyoke Water Power Company: Water source— well water high in organic content, 107 ppm total ion concentration, 25 ppm silica. Water after ion exchange treatment—conductivity less than 1 micromho, silica 0.004 ppm. Treated water is used in 1950 psi boilers. Water pretreatment consists of superchlorination, then filtration through activated carbon. Ion exchange takes place in a 4-bed demineralizer system consisting of a primary unit and a polishing unit. AMBERLITE IR-120 is used in the cation units, AMBERLITE IRA-402 in the anion beds.

Folder available free, shows how many different industries use AMBERLITE ion exchange resins for specific applications. Address your request to Dept. IE-1.
AMBERLITE IRA-402, a highly porous resin, has particular value in the system because it provides ready absorption of large organic molecules and releases them more easily during regeneration than do resins of standard porosity. At Holyoke, removal of foulant accumulated on AMBERLITE IRA-402 after repeated regenerations is accomplished by treatment with brine and caustic. If you use water for chemical processing or power generation, Rohm & Haas' wide selection of AMBERLITE ion exchange resins may offer you costsaving advantages. Write today. We will be glad to send you more information.
