For larger production infrastructures or for production units of bottled chlorine, adapted ventilation of the production room is needed.  <\/p>\n<p>[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_accordion _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; body_font_size=&#8221;16px&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_accordion_item title=&#8221;How do I dispose of the sodium hypochlorite solution?&#8221; open=&#8221;on&#8221; _builder_version=&#8221;4.16&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p><span style=\"font-size: 15.0pt; font-family: 'Helvetica',sans-serif; color: #1f424f;\">Due to its high oxidizing and antibacterial properties, sodium hypochlorite severely damages microorganisms and aquatic flora. Before throwing it away, it is important to neutralize the active chlorine with a dechlorination reagent, such as sodium thiosulfate, sodium sulfite or sodium metabisulfite. After dechlorination, the solution can be poured down the drains, following the instructions of the local authorities.  <o:p><\/o:p><\/span><\/p>\n<p>[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The WATA deviceThere are 4 different WATA devices for the production of sodium hypochlorite.
