Calcium chloride, wani sinadari da ake amfani da shi wajen magance najasa, wani sinadari ne da ba shi da sinadarai, wanda gishiri ne da ya kunshi chlorine da calcium, wani nau'in halide na ionic. Ion na Chloride na iya tsaftace ruwa, kashe kwayoyin cuta masu cutarwa, da kuma rage gubar ruwa. Ion na Calcium na iya maye gurbin cations na karfe da ke cikin ruwa, raba da kuma cire gubar ions na karfe masu nauyi, da kuma kawar da ruwan da ke fitowa daga calcium, wanda ke da kyakkyawan tasirin tsaftacewa da tsaftacewa.

Ga yadda za a gabatar da takamaiman rawar da calcium chloride ke takawa a cikin maganin najasa:

1. Calcium chloride da aka narkar a cikin ruwa bayan ion chloride yana da tasirin tsarkakewa.

2. Ion ɗin calcium na iya maye gurbin cations na ƙarfe a cikin ruwan da ke fitarwa, musamman a cikin tsarin sarrafa ruwan shara wanda ke ɗauke da cations na ƙarfe. Domin rage lalacewar abubuwa masu guba na cations na ƙarfe zuwa ga sashin sinadarai, ana amfani da calcium chloride a cikin tsarin kafin a fara magani don cire waɗannan abubuwa masu guba da cutarwa, wanda ke taka muhimmiyar rawa. Idan aka yi amfani da wannan abu a cikin sashin fitar da ruwa, ions ɗin chloride suna taka rawar kashe ƙwayoyin cuta. Ion ɗin calcium sun samar da calcium hydroxide wanda aka haƙa kuma aka cire shi ta hanyar hazo.

3. Rage PH da kuma daidaita tsarin hanyoyin samar da bututun najasa mai guba kafin lokaci don tsawaita tsawon rayuwar hanyar sadarwa ta bututu.

Tsarin aikace-aikacen musamman: Bayan an tattara ruwan shara a cikin tankin da ke daidaita ruwa, ana ɗaga ruwan shara zuwa tankin coagulation ta hanyar famfon ɗagawa.
