37 High stability (Original and Osmotic shock) Why is that so important? Heterodispers material after 300 cycles Broken beads build a lot of finest particle Problems : Capacity loss through lost material Low throughput with less production capacity High pressure loss through clog nozzles. Arising resin damage Further resin damage through high pressures Monodisperse resin Antwerpen street 2 after 900 cycles Transfer from SAC material into the anion vessel. High conductivity behind Anion filters High salt loading to the following mixed bed Sodium leakage High TOC leakage through oxidize finest resin particle 37 Lewatit Training Hans Jürgen Wedemeyer

94 Macroporous SBA resins for optimizing organic removal For removing of higher organic amounts macroporouse resins are an advantage. In the main the WBA (M+MP68) is responsible for TOC removing, but to increase the performance it is possible to install a styrene macroporouse SBA (M+ MP800) or a acrylic gel Type (A8071) This combination is able to remove approx. 3g TOC per cycle / liter resin (calculated with the installed WBA amount). For this performance higher NaOH amounts for regeneration are necessary Purified water Acrylic-resins give some advantage for aliphatic TOC removal (A8071; A8072; A8073) 94 Lewatit Training Hans Jürgen Wedemeyer

Possible steps before replacing with 10% NaCl In case of strong organic impurities of the resin (WBA/SBA) we recommend additional a pretreatment with a alkali brine cleaning procedure. In case of strong silica loading of the SBA (after exhaustion) we recommend additional a double NaOH regeneration and rinsing with a following NaCl exhaustion.
