Abubuwan da ke shafar amfani da flocculants a cikin maganin najasa

pH na najasa

Ƙimar pH na najasa yana da tasiri mai girma akan tasirin flocculants. Darajar pH na najasa yana da alaƙa da zaɓin nau'ikan flocculant, adadin flocculant da tasirin coagulation da lalata. Lokacin da darajar pH ta kasance<4, tasirin coagulation yana da rauni sosai. Lokacin da ƙimar pH ke tsakanin 6.5 da 7.5, tasirin coagulation ya fi kyau. Bayan darajar pH>8, tasirin coagulation ya sake zama mara kyau sosai.

Alkalin da ke cikin najasa yana da wani tasirin buffering akan ƙimar PH. Lokacin da alkalinity na najasa bai isa ba, yakamata a ƙara lemun tsami da sauran sinadarai don ƙarawa. Lokacin da ƙimar pH na ruwa ya yi girma, ya zama dole don ƙara acid don daidaita ƙimar pH zuwa tsaka tsaki. Ya bambanta, flocculant polymer ba su da tasiri ta hanyar pH.

zafin najasa

Zazzabi na najasa na iya shafar saurin flocculant. Lokacin da najasa ya kasance a cikin ƙananan zafin jiki, dankon ruwa yana da yawa, kuma yawan haɗuwa tsakanin flocculant colloidal barbashi da najasa a cikin ruwa yana raguwa, wanda ke hana manne juna na flocs; don haka, ko da yake an ƙara yawan adadin flocculants, samuwar flocs Har yanzu yana jinkiri, kuma yana da sako-sako kuma yana da kyau, yana da wuya a cire.

ƙazanta a cikin najasa

Matsakaicin girman nau'in ƙazanta a cikin najasa yana da amfani ga flocculation, akasin haka, ɓangarorin lafiya da daidaituwa za su haifar da tasirin flocculation mara kyau. Matsakaicin ƙananan ƙwayoyin najasa suna da lahani ga coagulation. A wannan lokacin, refluxing sediment ko ƙara coagulation aids iya inganta coagulation sakamako.

Nau'in flocculant

Zaɓin flocculant ya dogara ne akan yanayi da tattarawar daskararru da aka dakatar a cikin najasa. Idan daskararrun da aka dakatar a cikin najasa sun kasance kamar gel-kamar, ya kamata a fi son flocculants inorganic don lalata da daidaitawa. Idan flocs ƙananan ne, ya kamata a ƙara flocculants na polymer ko kuma a yi amfani da kayan aikin coagulation kamar gel ɗin silica da aka kunna.

A yawancin lokuta, haɗuwa da amfani da flocculants inorganic da polymer flocculants na iya inganta tasirin coagulation sosai da faɗaɗa iyakokin aikace-aikacen.

Sashi na flocculant

Lokacin amfani da coagulation don magance duk wani ruwa mai datti, akwai mafi kyawun flocculants da mafi kyawun sashi, wanda yawanci ana ƙaddara ta hanyar gwaje-gwaje. Yawan adadin kuzari na iya haifar da sake daidaitawar colloid.

Dosing jerin flocculant

Lokacin da aka yi amfani da flocculant da yawa, ana buƙatar tantance mafi kyawun tsarin sashi ta hanyar gwaje-gwaje. Gabaɗaya, idan aka yi amfani da flocculants na inorganic da flocculants na halitta tare, yakamata a fara ƙara flocculants na inorganic, sannan kuma a ƙara flocculants.
