In Unyango lwamanzi amdaka, ukususwa kwezinyithi ezinqunyanyisiweyo yikhonkco eliphambili. Ayisiyo kuphela le nto ifuna ukuphucula umgangatho wamanzi, ikwanciphisa ukunxiba kunye nokukrazula izixhobo kunye nokuvala. Okwangoku, iindlela zokususa ii-solids ezinqunyanyisiweyo zibandakanya i-sedation, ukugcwalisa, ukufihlakala, iflethi kunye nokusetyenziswa. Phakathi kwazo, indlela yokubhalwa isetyenziswa ngokubanzi ngenxa yokusebenza okuphezulu kunye noqoqosho. Ngale ndlela, i-polymer ebizwa ngokuba yiPolydadmac idlala indima ebalulekileyo.
I-Polydadmac, ogama ligqwesileyo li-Polyl Dimlyl Ammonium hloride, yi-molecular ephezulu. Iyenziwa ikakhulu yi-Polymeringise Domyldimithymonelam ye-monomer nge-chain yokukhula kwe-chanlization. Le ntetho ye-polymerizazazation idla ngokuqhutywa phantsi kwe-cataid okanye ityiwa, kunye ne-colly ye-polymer ye-polymer inokufunyanwa. Ihlala ityheli i-tyheli okanye imhlophe ukuba ibe ngumgubo otyheli okanye iigram. Inokuqina kakuhle kwaye inokusasazeka ngokulinganayo kwizisombululo ezizeleyo.
I-PolydadmadmacIne-canraity yentlawulo ephezulu kwaye iqhele iziphatha njenge polic polymer. Oku kuthetha ukuba i-adsopket ihlawuliswe ngokungafanelekanga isoldids slids kunye namasuntswana e-colloidal emanzini ukwenza iFlocs emikhulu, emva koko ukufezekisa ukususwa okusebenzayo kwezinyibilikisi ezinqunyanyisiweyo. I-Polydadmac ihlala isetyenziswa njengedyculant kwaye isetyenziswa ngokubanzi kwimimandla yonyango, kubandakanya unyango lwamanzi amdaka omzi-mveliso kunye nonyango lwe-Urbage. Inokwenza ngokukhawuleza i-flocs enkulu kwaye inee-flass ezinamanzi amdaka kunye nokususa ngokufanelekileyo iinyibilikisi, ii-ions ezinzima zentsimbi kunye nokungcoliseka kwendalo.
Kunyango lwamanzi amdaka ukusuka kwi-pulp kunye nee-Mills, indlela yentshukumo ye-polydadmac ikakhulu iboniswa ikakhulu kwezi zinto zilandelayo:
Ukungathathi cala kwezopolitiko: Ngenxa yokuba i-polydadmac inoxinano oluphezulu, inokukhawuleza ihlawulwe ngendlela engafanelekanga kunye namasuntswana e-colloidal, obangela ukuba baphulukane nokungathathi cala, kwaye emva koko bahlangane neflows yamasuntswana amakhulu.
Inyathelo lokutshayela: njengoko i-floc yenziwe, iya kutsala izinyibilikisi ezinqunyanyisiweyo kunye namasuntswana amiselweyo kumanzi amdaka kwi-FloC, afike kwi-sline yokwahlula-hlula ngokusebenzisa inyathelo.
Isiphumo se-Cat-Paymers: Iipoli zemolekyuli eziphakamileyo zinokwenza ubume benethiwekhi emdaka, i-racket inqunyanyiswe iinyibilikisi kunye namasuntswana ecolofayithi kuyo njengomnatha wokuloba, ngaloo ndlela ukufezekisa okufezekileyo.
Xa kuthelekiswa nezinye iindlela zonyango zamanzi amdaka, kusetyenziswa iPolydadmac ukunyanga i-Pump kunye namanzi amdaka ephepha anezibonelelo ezilandelayo:
Ukuxinana kweentlawulo eziphambili: Uxinzelelo lwe-Polydadmadmadmac yenze ukuba ifumane impumelelo ngakumbi i-folids enqunyanyisiweyo kunye namasuntswana e-colloidal, ukuphucula ukusebenza kakuhle konyango.
Ukuziqhelanisa okuqinileyo: I-Polydadmac ineziphumo ezilungileyo zonyango kwiintlobo ezahlukeneyo ze-pulp kunye namanzi amdaka amaphepha kwaye akachaphazelekanga kukutshintsha komgangatho wamanzi.
Ukusebenza kakuhle kunye nokusetyenziswa okuphezulu: usebenzisa i-polydadmac njengokoIflocculantKwaye i-cougant inokunciphisa kakhulu umthamo weechemicals, ngelixa kuphucula ukusebenza kakuhle konyango kunye nokunciphisa iindleko zokusebenza.
Kubuhlobo obubekiweyo: i-polydadmac sisimo se-cusic polymer. I-floc eveliswe emva kokusetyenziswa ayibolwanga ngokulula kwizinto eziyingozi kwaye inobuhlobo bokusingqongileyo.
Ukuqukumbela, i-polydadmac, njengeI-poleri yemolekyuli ephezulu, uneengenelo zokusebenza kakuhle, ukusebenzisa phantsi, kunye nokubeleka okusingqongileyo, kwaye udlala indima ebalulekileyo ekuphatheni amanzi amdaka kwi-pulwo kunye nemikhono yephepha. Ngexesha apho imeko yokhuseleko lwendalo kunzima ukuxhathisa, iPolydadmac yimveliso edumileyo yemichiza ehlangabezana neempawu zeemveliso zobuhlobo.
