General Information

START-UP PROCEDURE:

Before loading a column with ion exchange resins, it is important to observe a precise procedure for the filling of the columns, the backwashing of the resins and the conditioning prior to use. Moreover an appropriate conditioning procedure renders the resins compliant with existing regulations. This procedure is available from the Novasep's technical department.

CAUTION:

Acid and basic regenerant solutions are corrosive and should be handled with care. Nitric acid and other strong oxidizing agents can cause explosive reactions when mixed with resins.

The information and data contained herein are general and given in good faith for indicative purposes. Novasep makes no warranties either expressed or implied as to their accuracy and excludes any liability arising out of their use for specific applications.
