1. Tasirin zafin ruwa
Zafin ruwa yana da tasiri mai mahimmanci akan shan magunguna, da kuma ruwan zafi mai ƙarancin zafi a lokacin hunturu
yana da tasiri sosai ga shan ƙwayoyi, wanda yawanci yakan haifar da samuwar ƙwayoyin cuta masu laushi da laushi a hankali. Manyan dalilan sune:
Ruwan gishirin da ke cikin inorganic shine amsawar endothermic, kuma ruwan gishirin da ke cikin ƙananan zafin jiki yana da wahala.

Idan aka ƙara sinadarin coagulant a cikin ruwa, yawan sinadarin H+ a cikin ruwan yana ƙaruwa saboda hydrolysis na coagulant, wanda ke sa ƙimar pH na ruwan ta faɗi kuma tana hana hydrolysis. Don kiyaye pH a cikin mafi kyawun kewayon, ruwan ya kamata ya sami isassun abubuwan alkaline don rage H+. Ruwan halitta yana ɗauke da wani matakin alkaline (yawanci HCO3-), wanda zai iya rage H+ da aka samar yayin hydrolysis na coagulant, kuma yana da tasirin buffering akan ƙimar pH. Idan alkalinity na ruwan da ba shi da isasshen ruwa ko kuma an ƙara sinadarin coagulant da yawa, ƙimar pH na ruwan zai ragu sosai, yana lalata tasirin coagulant.
3. Tasirin yanayi da yawan ƙazanta a cikin ruwa
Girman barbashi da kuma ƙarfin cajin SS a cikin ruwa zai shafi tasirin coagulation. Gabaɗaya, diamita na barbashi ƙarami ne kuma iri ɗaya, kuma tasirin coagulation ba shi da kyau; yawan barbashi a cikin ruwa yana da ƙasa, kuma yuwuwar karowar barbashi ƙarami ne, wanda ba shi da kyau ga coagulation; lokacin da turbidity ya yi yawa, don lalata colloid a cikin ruwa, yawan sinadarai da ake buƙata zai ƙaru sosai. Idan akwai adadi mai yawa na kwayoyin halitta a cikin ruwa, ana iya shanye shi ta hanyar ƙwayoyin yumbu, don haka yana canza halayen saman barbashi na colloidal na asali, yana sa barbashi na colloidal su fi karko, wanda zai yi tasiri sosai ga tasirin coagulation. A wannan lokacin, dole ne a ƙara mai hana iska a cikin ruwa don lalata tasirin kwayoyin halitta, inganta tasirin coagulation.
Gishirin da aka narke a cikin ruwa suma na iya shafar tasirin coagulation. Misali, idan akwai adadi mai yawa na calcium da magnesium ions a cikin ruwan halitta, yana taimakawa wajen coagulation, yayin da adadi mai yawa na Cl- ba ya taimakawa wajen coagulation. A lokacin ambaliyar ruwa, ruwa mai yawan turbidity wanda ke ɗauke da adadi mai yawa na humus yana shiga cikin shukar saboda goge ruwan sama, kuma yawan chlorine da coagulant da ake amfani da su gabaɗaya sun dogara ne akan wannan.
