Domin fitarwa ko sake amfani da Najasa bayan Jiyya, ana buƙatar amfani da sinadarai iri-iri a cikin aikin Jiyya na Najasa.A yau,PAM (Polyacrylamide) masu samar da kayayyakizai gaya muku game da flocculants:
Flocculant: Wani lokaci kuma ana kiransa coagulant, ana iya amfani dashi azaman hanyar ƙarfafa rarrabuwar ruwa mai ƙarfi, kuma ana iya amfani dashi a cikin tanki na farko, tankin daidaitawa na sakandare, tankin flotation, jiyya na manyan makarantu ko jiyya na ci gaba da sauran hanyoyin haɗin gwiwa.
Ana amfani da flocculants azaman hanyar ƙarfafa rarrabuwar ruwa mai ƙarfi a fagen kula da najasa.Ana iya amfani da su don ƙarfafa ƙaddamarwa na farko na najasa, flotation jiyya da kuma na biyu sedimentation bayan kunna sludge tsari, kuma za a iya amfani da su ga manyan makarantu ko ci-gaba jiyya na najasa.Lokacin amfani da kwandishan kafin bushewar wuce haddi sludge, flocculants da coagulant zama sludge conditioners ko dehydrating jamiái.
Lokacin amfani da flocculants na gargajiya, ana iya amfani da hanyar ƙara kayan taimako na coagulant don haɓaka tasirin flocculation.Misali, yin amfani da silicic acid da aka kunna azaman taimakon coagulant don flocculants na inorganic kamar sulfate sulfate da aluminum sulfate da ƙara su a jere na iya cimma kyakkyawan flocculat.Saboda haka, a cikin sharuddan layman, inorganic polymer flocculant IPF an shirya shi ta hanyar haɗa taimakon coagulant da flocculant sannan a haɗa su tare don sauƙaƙe aikin mai amfani.
Coagulation magani yawanci sanya a gaban m-ruwa rabuwa makaman, da kuma hade tare da rabuwa makaman, shi zai iya yadda ya kamata cire dakatar da daskararru da colloidal abubuwa tare da barbashi size of 1nm zuwa 100μm a cikin raw ruwa, rage effluent turbidity da CODCr, kuma za a iya amfani da su a cikin pretreatment na najasa magani matakai.Jiyya, ci-gaba magani, kuma za a iya amfani da saura sludge jiyya.Maganin coagulation kuma yana iya kawar da ƙwayoyin cuta da ƙwayoyin cuta a cikin ruwa yadda ya kamata, da kuma cire man emulsified, chroma, ion ƙarfe mai nauyi da sauran gurɓataccen ruwa a cikin najasa.Yawan cire sinadarin phosphorus da ke cikin najasa zai iya kaiwa kashi 90% yayin da ake amfani da ruwan sha don maganin phosphorus.~95%, shine hanya mafi arha kuma mafi inganci na kawar da phosphorus.
A cikin aiwatar da maganin najasa, za a yi amfani da wasu wakilai.A yau, daKamfanin PAMdaya kawai ya gabatar da su.Shin har yanzu kuna fahimta?Kula da Yuncang kuma amsa ƙarin ilimin kula da najasa a gare ku!
