Waa maxay kiimikooyinka inta badan loo isticmaalo dhirta lagu daweeyo bulaacadaha?

Markaad Tixgalinayso kaagaDaaweynta Biyaha QashinkaHabka, Ka Bilow Go'aaminta Waxaad U Baahan Tahay Inaad Ka Saarto Biyaha Si Aad U Daboosho Shuruudaha Soo Dajinta. Daawaynta Kiimikada saxda ah, waxaad ka saari kartaa Ions-ka iyo adkaha yaryar ee biyaha ku milmay, iyo sidoo kale adkaha la laalay. Kiimikooyinka Loo Isticmaalo Dhirta Daawaynta Bullaacadaha Inta Badan Waxa Ka Mid Ah:Flocculant, Ph Regulator, Coagulant.

Flocculant
Flocculans waxaa loo isticmaalaa warshado iyo codsiyo kala duwanSi aad gacan uga geysato ka-saarista adkaha joogsiga ah ee biyaha wasakhda ah Adigoo ku ururinaya wasakhaha go'yaal ama "flocs" kuwaas oo sabbaynaya dusha sare ama dega xagga hoose. Waxa kale oo loo isticmaali karaa in lagu jilciyo lime, Isku-ururinta dhoobada iyo fuuqbaxa adag. Flocculants dabiici ah ama macdanta waxaa ka mid ah Silica Firfircoon iyo Polysaccharides, halka Flocculants synthetic yihiin caadi ahaan Polyacrylamide.
Iyada oo ku xidhan Kharashka iyo Isku-dhafka Kiimikada ee Biyaha Wasaha, Flocculans waxa laga yaabaa in keligood loo isticmaalo ama lagu daro xinjiriyeyaasha. Flocculant-yadu waxay kaga duwan yihiin xinjirayaasha in ay badanaa yihiin polymers, halka xinjirayaashu ay inta badan yihiin cusbo. Cabbirkooda Molecular (Miisaankooda) iyo Cufnaanta Cufnaanta (Boqolkiiba Molecules ee leh Anionic ama Cationic Charges) way kala duwanaan karaan si ay "isku dheelitiraan" ujrada walxaha biyaha ku jira oo ay u keenaan inay isku tagaan oo ay fuuq baxaan. Guud ahaan, Anionic Flocculants ayaa loo isticmaalaa in lagu dabo Walxaha Macdanta, halka Cationic Flocculants loo isticmaalo in lagu dabiyo Walxaha dabiiciga ah.

PH Maamule
Si biraha iyo wasakhooyinka kale ee wasakhaysan looga saaro biyaha wasakhda ah, hagaha pH ayaa la isticmaali karaa. Kor u qaadida pH ee biyaha, oo sidaas awgeed kordhinaysa tirada ion hydroxide taban, tani waxay keeni doontaa ion birta si togan loo dallaco si ay ugu xidhmaan ion hydroxide-ka taban. Tani waxay keenaysaa shaandhaynta ka soo baxay birta cufan iyo kuwa aan milmi karin.

xinjirowga dhiigga
Nidaam kasta oo lagu daweeyo biyaha wasakhda ah ee daaweeya adkaha la hakiyay, xinjirayaashu waxay isku dari karaan wasakhaha la hakiyay si fudud looga saaro. Kiimikada Kiimikada loo isticmaalo ka-hortagga biyaha wasakhda warshadaha ayaa loo qaybiyaa mid ka mid ah laba qaybood: Organic iyo Inorganic.
Xididdada aan Organic-ka ahayn waa qiimo-wax-ku-ool ah waxaana loo isticmaali karaa codsiyo kala duwan. Waxay si gaar ah wax ku ool u yihiin biyaha ceeriin ee wax kasta oo turbidity hooseeya, iyo codsigan kuma haboona xinjirowga dabiiciga ah. Marka lagu daro biyaha, xinjirayaasha aan Orgaaniga ahayn ee Aluminium ama Birta ayaa soo da'aya, iyagoo nuugaya wasakhda ku jirta biyaha oo nadiifiya. Tan waxaa loo yaqaanaa habka "Sweep-and-flocculate" Inta uu wax ku ool yahay, Hawshu waxa ay kordhisaa wadarta xadiga dhoobada ee loo baahan yahay in biyaha laga saaro. Xididiyeyaasha aan noolayn ee caadiga ah waxaa ka mid ah aluminium sulfate, aluminium chloride, iyo Ferric Sulfate.
Xididiyeyaasha Dabiiciga ah waxay leeyihiin faa'iidooyinka qiyaasta hooseeya, wax soo saarka dhoobada yar iyo wax saameyn ah oo ku saabsan Ph ee Biyaha la daaweeyay. Tusaalooyinka xinjirayaasha dabiiciga ah ee caadiga ah waxaa ka mid ah Polyamines iyo Polydimethyl Diallyl Ammonium Chloride, iyo sidoo kale Melamine, Formaldehyde iyo Tannins.
