M'madera amasiku ano, kuteteza ndi kugwiritsa ntchito madzi kwakhala chinthu chofunika kwambiri padziko lonse lapansi.Chifukwa cha kukula kwa mafakitale, kuipitsidwa kwa madzi kukukula kwambiri.Momwe mungasamalire ndi kuyeretsa bwino zimbudzi zakhala vuto lachangu lomwe likuyenera kuthetsedwa.Munkhaniyi, PAM polima flocculant idakhalapo, idakondedwa ndi ogwiritsa ntchito ambiri ndi mankhwala ake komanso momwe amapangira madzi.
PAM, dzina lonse la Polyacrylamide, ndi polymer flocculant.Ndi mtundu wa polima wapamwamba wokonzedwa ndi polymerization yaulere ya acrylamide.Chogulitsacho chimalemera kwambiri ndipo chimatha kupanga tinthu tating'onoting'ono tomwe timatalika, chomwe chimabalalitsa bwino komanso kukhazikika m'madzi, ndipo amatha kutsatsa bwino ndikuchotsa zodetsa zamadzi.
Njira yogwiritsira ntchito PAM polima flocculant ndiyosavuta.Choyamba, njira ya PAM imawonjezeredwa m'madzi kuti athetsedwe, ndiyeno poyambitsa kapena kusonkhezera makina, PAM ndi madzi zimasakanizidwa bwino kuti apange flocculent yaikulu.Ma flocculents awa adzakhazikika m'madzi, motero kukwaniritsa cholinga chochotsa zowononga.Chifukwa cha kukhazikika kwa mankhwala a mankhwala, madzi oyeretsedwa amatha kutulutsidwa mwachindunji ku chilengedwe popanda chithandizo chachiwiri.
Ubwino wa mankhwalawa sikuti amangogwira ntchito bwino pamankhwala amadzi.Choyamba, ndizotsika mtengo kugwiritsa ntchito.Poyerekeza ndi njira zachikhalidwe zoyeretsera madzi, monga mvula, kusefera, ndi zina zotero, kugwiritsa ntchito mankhwalawa kumakhala kosavuta komanso kopanda ndalama.Kachiwiri, mankhwalawa sakhudza kwambiri madzi.Sichimasintha mankhwala amadzi, choncho sichimayambitsa kuipitsidwa kwachiwiri kwa chilengedwe.Pomaliza, mankhwala zotsatira za mankhwala ndi zabwino, akhoza bwino kuchotsa inaimitsidwa nkhani ndi kusungunuka zoipitsa madzi, kusintha mandala madzi ndi zomverera zizindikiro.
Nthawi zambiri, PAM polima flocculant ndi chida chothandiza komanso chosamalira zachilengedwe.Kuwonekera kwake sikungopereka njira yatsopano yothetsera vuto la kuipitsidwa kwa madzi, komanso kumapereka chithandizo champhamvu chaukadaulo cholimbikitsa kasamalidwe ka madzi obiriwira komanso okhazikika.M'tsogolomu, ndi kupita patsogolo kwa sayansi ndi luso lamakono komanso kupititsa patsogolo chidziwitso cha chilengedwe, tili ndi zifukwa zokhulupirira kuti mankhwalawa adzakhala ndi gawo lalikulu pa ntchito yosamalira madzi.
