Chlorine yotsalira imatanthawuza kuti mankhwala ophera tizilombo okhala ndi chlorine atayikidwa m'madzi, kuwonjezera pakudya gawo la kuchuluka kwa chlorine polumikizana ndi mabakiteriya, ma virus, organic matter, ndi inorganic matter m'madzi, gawo lotsala la kuchuluka kwa chlorine. klorini amatchedwa residual klorini. Iwo akhoza kugawidwa mu ufulu zotsalira klorini ndi kuphatikiza yotsalira klorini. Kuchuluka kwa ma klorini awiri otsalirawa kumatchedwa total residual chlorine, yomwe ingagwiritsidwe ntchito kusonyeza momwe matupi amadzi amapha tizilombo toyambitsa matenda. Mabungwe oyenerera m'malo osiyanasiyana amatha kusankha kupeza chlorine yotsalira kapena chlorine yotsalira molingana ndi miyezo yoyenera komanso mikhalidwe yamadzi. Pakati pawo, klorini yotsalira yaulere nthawi zambiri imakhala yaulere ngati Cl2, HOCl, OCl-, etc.; ophatikizana otsala klorini ndi chloramines NH2Cl, NHCl2, NCl3, etc. anapanga pambuyo zimene chlorine ufulu ndi ammonium zinthu. Klorini yotsalira yomwe timati nthawi zambiri imatanthawuza klorini yotsalira yaulere.
Klorini yotsalira/yotsala yonse imakhala ndi zofunika zosiyanasiyana pamadzi akumwa apanyumba, madzi apamtunda, ndi zimbudzi zachipatala. Pakati pawo, "Drinking Water Sanitation Standard" (GB 5749-2006) imafuna kuti chlorine yotsalira yamadzi a fakitale ya madzi opangira madzi iwongoleredwe pa 0.3-4.0mg/L, ndi chlorine yotsalira kumapeto kwa maukonde chitoliro adzakhala osachepera 0.05mg/L. Kuchuluka kwa klorini yotsalira m'madzi akumwa apakati pamadzi apakati kuyenera kukhala kosakwana 0.03mg/L. Kuchuluka kwa klorini kotsalako kukakhala kokulirapo kuposa 0.5mg/L, ziyenera kunenedwa ku dipatimenti yoyang'anira zachilengedwe. Malinga ndi nkhani zosiyanasiyana zotulutsira madzi ndi minda yotulutsa zimbudzi zachipatala, zofunika kuti chlorine yotsalira yotsalira pamalo otulutsirako disinfection dziwe ndi yosiyana.
Chifukwa chlorine yotsalira ndi klorini yotsalira yonse ndi yosakhazikika m'madzi, mawonekedwe awo omwe alipo amakhudzidwa mosavuta ndi zinthu monga kutentha ndi kuwala. Choncho, kudziwika kwa klorini yotsalira ndi klorini yotsalayo nthawi zambiri tikulimbikitsidwa kuti tidziwike mwamsanga pamalo opangira zitsanzo kuti zitsimikizire kulondola kwake. Njira zodziwira zotsalira za klorini ndi klorini yotsalira yonse zikuphatikizapo "HJ 586-2010 Kutsimikiza kwa klorini yaulere ndi klorini yonse mu khalidwe la madzi N, N-diethyl-1,4-phenylenediamine spectrophotometric njira", electrochemical njira, reagent njira, etc. Lianhua Technology LH-CLO2M Portable Chlorine Meter imapangidwa kutengera DPD spectrophotometry, ndipo mtengo ukhoza kupezeka mu mphindi imodzi. Amagwiritsidwa ntchito kwambiri poyang'anira nthawi yeniyeni ya klorini yotsalira ndi klorini yotsalira yonse chifukwa cha kuzindikira kwake komanso kugwira ntchito mosavuta kuntchito.
