    6.7.2 Chemical cleaning of filter panels Long-term clogging of the filter media can be caused by, among others, iron, calcium or organic fouling. This clogging can normally be removed through chemical cleaning. Three proven pro- ducts that do not affect the life of the filter media are dilute hydrochloric acid (HCl), dilute sodi- um hypochlorite (NaClO) and dilute sodium hydroxide (NaOH).
