Ndi Mankhwala Otani Amene Amagwiritsidwa Ntchito Nthawi zambiri M'mafakitale Ochapira Zonyansa?

Poganizira AnuChithandizo cha Madzi OtayiraNjira, Yambani Posankha Zomwe Muyenera Kuchotsa M'madzi Kuti Mukwaniritse Zofunikira Zotulutsa. Ndi Mankhwala Oyenera Amankhwala, Mutha Kuchotsa Ma Ioni Ndi Zida Zing'onozing'ono Zosungunuka M'madzi, Komanso Zomwe Zimayimitsidwa. Mankhwala Omwe Amagwiritsidwa Ntchito M'mafakitale Azachimbudzi Amaphatikizapo:Flocculant, Ph Regulator, Coagulant.

Flocculant
Ma Flocculants Amagwiritsidwa Ntchito Pamafakitale Osiyanasiyana Ndi NtchitoKuthandizira Kuchotsa Zolimba Zoyimitsidwa M'madzi Anyansi Mwa Kuyika Zoipitsa M'mapepala Kapena "Ziphuphu" Zomwe Zimayandama Pamwamba Kapena Kukhazikika Pansi. Atha Kugwiritsidwanso Ntchito Kufewetsa Laimu, Kuyika Pang'onopang'ono Sludge Ndi Dehydrate Solids. Ma Flocculants Achilengedwe Kapena Maminolo Amaphatikiza Silika Yogwira Ndi Polysaccharides, Pomwe Ma Flocculants Opanga Nthawi zambiri Amakhala Polyacrylamide.
Kutengera Kulimbitsidwa Ndi Ma Chemical Mapangidwe Amadzi Otayidwa, Flocculants Atha Kugwiritsidwa Ntchito Pawokha Kapena Kuphatikiza ndi Coagulants. Ma Flocculants Amasiyana Ndi Ma Coagulants Chifukwa Nthawi zambiri Amakhala Ma polima, pomwe Ma Coagulants Nthawi zambiri amakhala Mchere. Kukula Kwawo Kwa Mamolekyulu (Kulemera) Ndi Kuchuluka Kwa Charge (Chiperesenti Cha Mamolekyulu Okhala Ndi Anionic Kapena Cationic Charge) Amatha Kusiyanasiyana Kuti "Kusamalitsa" Kuchulukira Kwa Tinthu Zomwe Zili M'madzi Ndikuwapangitsa Kuti Aziphatikizana Pamodzi Ndi Kutaya Madzi. Nthawi zambiri, Anionic Flocculants Amagwiritsidwa Ntchito Kukola Tinthu Zamchere, Pomwe Ma Cationic Flocculants Amagwiritsidwa Ntchito Kukola Tinthu Zamoyo.

PH Wowongolera
Kuchotsa zitsulo ndi zonyansa zina zosungunuka m'madzi onyansa, pH regulator ingagwiritsidwe ntchito. Pokweza pH ya madzi, ndikuwonjezera kuchuluka kwa ayoni a hydroxide negative, izi zipangitsa kuti ayoni achitsulo opangidwa bwino kuti agwirizane ndi ayoni omwe ali ndi hydroxide oyipa. Izi zimapangitsa kuti tinthu tating'ono ting'onoting'ono tichotsedwe.

Coagulant
Pa Njira Iliyonse Yoyeretsera Madzi Otayira Zomwe Zimagwira Zolimba Zoyimitsidwa, Ma Coagulants Atha Kuphatikiza Zoyipa Zoyimitsidwa Kuti Zichotsedwe Mosavuta. Ma Chemical Coagulants Omwe Amagwiritsidwa Ntchito Pokonzekera Madzi Otayidwa Amafakitale Amagawidwa M'magulu Awiri: Organic ndi Inorganic.
Ma Inorganic Coagulants Ndiwotsika mtengo Ndipo Atha Kugwiritsidwa Ntchito Pamitundu Yambiri Yamapulogalamu. Ndiwothandiza Kwambiri Pamadzi Aawisi Amtundu Wambiri Wotsika, Ndipo Kugwiritsa Ntchito Izi Sikoyenera Kwa Organic Coagulants. Mukawonjezedwa ku Madzi, Ma Inorganic Coagulants Ochokera ku Aluminiyamu Kapena Iron Precipitate, Amachotsa Zoyipa M'madzi Ndikuwayeretsa. Izi Zimadziwika Kuti "Sesa-Ndi-Flocculate" Mechanism. Ngakhale Kuti Ndi Yogwira Ntchito, Njirayi Imawonjezera Kuchuluka Kwa Dothi Lomwe Limafunika Kuchotsedwa M'madzi. Ma Inorganic Coagulants Odziwika Amaphatikizapo Aluminium Sulfate, Aluminium Chloride, ndi Ferric Sulfate.
Ma Organic Coagulants Ali Ndi Ubwino Wotsitsa Mlingo, Pang'ono Kupanga Sludge Ndipo Palibe Mphamvu Pa Ph Ya Madzi Othiridwa. Zitsanzo za Common Organic Coagulants Zimaphatikizapo Polyamines Ndi Polydimethyl Diallyl Ammonium Chloride, Komanso Melamine, Formaldehyde Ndi Tannins.
