PAM Flocculant: mankhwala amphamvu opangira madzi a mafakitale

Polyacrylamide(PAM) ndi hydrophilic synthetic polima yomwe imagwiritsidwa ntchito kwambiri pochiritsa madzi. Amagwiritsidwa ntchito makamaka ngati flocculant ndi coagulant, mankhwala omwe amachititsa kuti tinthu tating'onoting'ono tamadzi tiphatikizidwe mumagulu akuluakulu, potero kuthandizira kuchotsedwa kwawo kupyolera mu kumveka kapena kusefa. Kutengera mtundu wamadzi onyansa, gwiritsani ntchito cationic, anionic, kapena PAM yopanda ionic. Polyacrylamide imapereka maubwino angapo pamankhwala amadzi, kuphatikiza kugwira ntchito kwake pamitundu yosiyanasiyana ya pH, kutentha, ndi ma turbidity. Mphamvu ya coagulation imatha kuyesedwa pogwiritsa ntchito mayeso a Jar kapena muyeso wa turbidity.

Polyacrylamide angagwiritsidwe ntchito mu mafakitale mankhwala mankhwala, kuchimbudzi, mankhwala amadzi onyansa, etc. Mu zomera madzi mankhwala, Polyacrylamide ntchito njira zosiyanasiyana, kuphatikizapo pulayimale ndi yachiwiri kumveketsa, kusefera, ndi disinfection. Pakuwunikira koyambirira, amawonjezeredwa kumadzi osaphika kuti alimbikitse kukhazikika kwa zolimba zoyimitsidwa, zomwe zimachotsedwa ndi sedimentation kapena flotation. Mu kumveketsa yachiwiri, Polyacrylamide ntchito zina kumveketsa bwino madzi mankhwala pochotsa zotsalira inaimitsidwa zolimba ndi adsorbed organic kanthu.

Mfundo yogwirira ntchito yapolyacrylamide flocculantndi: pambuyo kuwonjezera PAM yankho, PAM adsorbs pa particles, kupanga milatho pakati pawo. Mu dziwe lapachiyambi, limamatira kupanga magulu akuluakulu, ndipo thupi lamadzi limakhala losokonezeka panthawiyi. Pambuyo pakukula kwamagulu ambiri ndikukhala okhuthala, amasamuka ndikumira pang'onopang'ono pakapita nthawi, ndipo gawo lapamwamba la madzi osaphika lidzamveka bwino. Izi aggregation ndondomeko bwino kuthetsa makhalidwe a particles, kuwapangitsa mosavuta kuchotsa pa kumveka kapena kusefera. Polyacrylamide nthawi zambiri ntchito osakaniza coagulants ndi flocculants kukwaniritsa mulingo woyenera kumveketsa ndi kusefera ntchito.

Polyacrylamide imagwiranso ntchito yofunikira pakusefera kwamadzi. Nthawi zambiri amagwiritsidwa ntchito ngati zosefera zisanachitike muzosefera kapena njira zina zosefera zakuthupi kuti achotse zolimba zoyimitsidwa ndi turbidity. Mwa kusintha kuchotsedwa kwa tinthu ting'onoting'ono, polyacrylamide imathandiza kuonetsetsa kuti kusefa kowoneka bwino, koyera.

Polyacrylamide ndi polima yokhazikika komanso yopanda poizoni yomwe imawonongeka kudzera munjira zachilengedwe kapena njira zamankhwala zamankhwala. Tiyenera kukumbukira kuti njira yowonongeka imapangitsa kuti pansi pakhale poterera kwambiri, zomwe zingayambitse kugwa.

Komabe, kuchuluka kwa PAM komwe kumagwiritsidwa ntchito kumadalira mtundu wa madzi onyansa komanso zomwe zili muzitsulo zolimba zoyimitsidwa, komanso kukhalapo kwa mankhwala ena, ma asidi, ndi zonyansa m'madzi. Zinthu izi zitha kukhudza coagulation zotsatira za PAM, kotero kusintha koyenera kuyenera kupangidwa pakagwiritsidwa ntchito. Zogulitsa za PAM zokhala ndi mamolekyu osiyanasiyana, madigiri a ionic, ndi mlingo ziyenera kusankhidwa mosamala pamitundu yosiyanasiyana yamadzi oyipa.
