Ubwumvikane buke busanzwe muguhitamo PAM

Polyacrylamide(PAM), nkibisanzwe bikoreshwa na polymer flocculant, ikoreshwa cyane muburyo butandukanye bwo gutunganya imyanda. Nyamara, abakoresha benshi baguye mubwumvikane buke mugihe cyo gutoranya no gukoresha inzira. Iyi ngingo igamije kwerekana ibyo kutumva no gutanga ibitekerezo byukuri.

Kutumva nabi 1: Iyo uburemere bwa molekile nini, niko imikorere ya flocculation ikora.

Iyo uhisemo polyacrylamide, abantu benshi batekereza ko moderi ifite uburemere bunini bwa molekile igomba kuba ifite imikorere myiza ya flocculation. Ariko mubyukuri, hariho amajana menshi ya polyacrylamide, akwiranye nuburyo butandukanye bwamazi meza. Imiterere y’amazi mabi yakozwe ninganda mu nganda zitandukanye ziratandukanye. Agaciro pH numwanda wihariye wamazi atandukanye aratandukanye cyane. Birashobora kuba acide, alkaline, itabogamye, cyangwa irimo amavuta, ibinyabuzima, ibara, imyanda, nibindi. Kubwibyo rero, biragoye ko ubwoko bumwe bwa polyacrylamide bwuzuza ibikenewe byose byo gutunganya amazi mabi. Uburyo bwiza ni ukubanza guhitamo icyitegererezo ukoresheje ubushakashatsi, hanyuma ugakora ibizamini bya mashini kugirango umenye dosiye nziza kugirango ugere ku ngaruka zihenze cyane.

Kudasobanukirwa 2: Iyo urwego rwiboneza rwibanze, nibyiza

Mugihe utegura ibisubizo bya polyacrylamide, abayikoresha benshi bizera ko uko kwibanda cyane, nibyiza bya flocculation. Ariko, iki gitekerezo ntabwo aricyo. Mubyukuri, kwibumbira hamwe kwa PAM bigomba kugenwa ukurikije imyanda yihariye. Muri rusange, ibisubizo bya PAM bifite 0.1% -0.3% bikwiranye no guhindagurika no gutembera, mugihe kwibumbira mumazi ya komine ninganda ari 0.2% -0.5%. Iyo hari umwanda mwinshi mumyanda, ubunini bwa PAM bushobora gukenera kwiyongera muburyo bukwiye. Kubwibyo, gushyira mu gaciro gushyira mu gaciro bigomba kugenwa hakoreshejwe ubushakashatsi mbere yo gukoresha kugirango umenye neza ingaruka zikoreshwa.

Kutumva nabi 3: Igihe kinini cyo gushonga no gukurura, nibyiza

Polyacrylamide nigice cyera cya kristalline kigomba gushonga burundu kugirango kigere ku ngaruka nziza. Abakoresha benshi batekereza ko igihe kinini cyo gushonga no gukurura ari byiza, ariko mubyukuri ntabwo aribyo. Niba igihe cyo gukurura ari kirekire cyane, bizatera gucika igice cyurunigi rwa PAM kandi bigira ingaruka kumikorere ya flocculation. Muri rusange, igihe cyo gushonga no gukurura ntigomba kuba munsi yiminota 30 kandi kigomba kongerwa uko bikwiye mugihe ubushyuhe buri hasi mugihe cy'itumba. Niba iseswa nigihe cyo gukurura ari gito cyane, PAM ntizashonga burundu, bizavamo kutabasha gukora neza flokculasiyo yihuse mumyanda. Kubwibyo, abakoresha bagomba kwemeza gusesa bihagije no gukurura igihe mugihe babikoresha kugirango barebe ingaruka za flocculation ya PAM.

Kutumva nabi 4: Ionicity / Ionic degree niyo shingiro ryonyine ryo guhitamo

Nka kimwe mu bimenyetso byingenzi byerekana polyacrylamide, ionicity bivuga ububi bwiza kandi bwiza hamwe nubucucike bwabwo. Abantu benshi bitondera cyane ionicity mugihe baguze, batekereza ko hejuru ari byiza. Ariko mubyukuri, urwego rwa ionicity rujyanye nubunini bwuburemere bwa molekile. Iyo hejuru ya ionicity, uburemere bwa molekile ntoya, nigiciro kinini. Mubikorwa byo gutoranya, usibye ionicity, ibindi bintu bigomba kwitabwaho, nkibihe byihariye byubuziranenge bwamazi, ibisabwa kugirango ingaruka ziterwa na flokculasiyo, nibindi rero, icyitegererezo ntigishobora gutoranywa hashingiwe gusa kurwego rwa ionisation. Ibindi bizamini birasabwa kugirango umenye icyitegererezo gikenewe.

Nka aflocculant, polyacrylamide igira uruhare runini mu nganda zitunganya amazi. Mugihe ukeneye guhitamo ibisobanuro bikwiranye, nyamuneka nyandikira.
