High Capacity Mixed-Bed Resin
ProBlend™ LT-HC (P/N ER30005) is a high grade mixed-bed made to attain very low leachable TOC levels. The product is fully tested to ensure its ability to achieve 18 megohm resistivity. Each batch is also tested to ensure its ability to rinse to below 25 ppb of leachable TOC in less than 25 bed volumes from start up and to below 10 ppb in less than 50 bed volumes.

ProBlend-HC Pressure Drop Graph
PRESSURE DROP — The graph above shows the expected pressure loss per foot of bed depth as a function of flow rate at various temperatures.
ProBlend-HC Backwash Graph
BACKWASH — The backwash step is used to separate the components prior to regeneration and to remove particles. The separation is optimized at a bed expansion of 50 to 75 percent.
Extended exposure to strong oxidizers (such as chlorine, hydrogen peroxide, and concentrated nitric acid) degrade the structural backbone of the resin and should be avoided.
CAUTION: DO NOT MIX ION EXCHANGE RESINS WITH STRONG OXIDIZING AGENTS. Nitric acid and other strong oxidizing agents can cause explosive reactions when mixed with organic materials such as ion exchange resins.

Hydroxides measured in anion component prior to mixing. The CO3 level measured immediately after production is held to the same specifications as the SO4. Actual CO3 levels may change during storage and shipment due to adsorption of CO2 from the atmosphere. We recommend keeping all containers sealed closed until use. For longer storage times, gas barrier packaging (mylar) is suggested. Contact your SWT representative for more information.
