Volgens GB 4287-2012 bedraagt de chloridegrenswaarde voor de lozing van industrieel afvalwater <strong>500 mg\/l<\/strong>. Traditionele offline testmethoden leverden slechts om de 4\u20136 uur resultaten op, waardoor realtime procescontrole vrijwel onmogelijk was.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Toen het chloridegehalte \u2019s nachts tijdens het verversen van de kleurstof plotseling sterk steeg, overschreed het afvalwater de wettelijke drempelwaarden voordat de operators konden ingrijpen. Over een periode van twee jaar leidde dit tot <strong>maandelijkse boetes van gemiddeld 28.000 yen<\/strong> en herhaalde waarschuwingen van milieu-instanties.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">De oplossing: continue monitoring met de KWS-3100-chloride-ionsensor<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">De faciliteit heeft de <strong>KWS-3100 online chloride-ionsensor<\/strong> bij het eindpunt van de lozing van het afvalwater.
