Floccut - Aluminium Sulphate vs Poly aluminium chloride

Induru ni inzira yashizwemo ibice byahagaritswe nabi bihari muguhagarikwa neza mumazi birahungabana. Ibi bigerwaho wongeyeho cougulant yashizwe neza. Ibyiza muri coagulant itesha agaciro ikirego kibi gihe mumazi (ni ukuvuga kwiyongera). Ibice bimaze guhungabana cyangwa kutabogama, inzira yo kwikuramo ibaho. Ibice byahungabanye bihuza nibice binini kandi binini kugeza biremereye bihagije kugirango bakemure ibicuruzwa cyangwa binini bihagije kugirango bafate ibibyimba byo mu kirere no kureremba.

Uyu munsi tuzareba neza imiterere ya Flocctulation yibice bibiri bisanzwe: Poly Aluminium chloride na almunum sulfate.

Aluminium sulfate: Aluminium sulfate ni acidic muri kamere. Ihame ryakazi rya Suminum Sulfate ni rikurikira: Sulmunum Sulfate itanga hydroxide ya aluminium, al (0h) 3. Aluminum hydroxides ifite phi ya ph, hejuru itazahinduka hydrolyside cyangwa, hydrolzated aluminiyumu yamashanyarazi ya 8.5), bityo PH yo hejuru igomba kugenzurwa neza kugirango ikomeze kugirango ikomeze murwego rwa 5.8-8.5. Alkalinity mumazi igomba kuba ihagije mugihe cya Sloctulation kugirango ikemure ko hydroxide itemewe yuzuye kandi iruse. Kuraho ibara nibikoresho bya colloidal ukoresheje guhuza adsorption na hydrolysis kuri / muri sydroxide yicyuma. Kubwibyo, idirishya rikora rya pumunum sulfate rya aluminiyum 5.8-8.5, ni ngombwa rero kwemeza p p p p p p p ph mugihe ukoresheje pulfate ya aluminiyumu.

Polyilumum chloride(PAC) ni imwe mu miti myiza yo kuvura amazi menshi ikoreshwa muri iki gihe. Bikoreshwa cyane mumazi yo kunywa no kuvura amazi yo kwanduza kubera imikorere yacyo menshi kandi ubwinini bwa PH nubushyuhe ugereranije nububiko bwamazi. PAC irahari mumanota menshi atandukanye hamwe na alumina yibanda kuri 28% kugeza 30%. Alumina kwibanda ntabwo aricyo gisuzumwe cyonyine mugihe uhisemo icyiciro cya PAC kugirango ukoreshe.

PAC irashobora gufatwa nkimbaga ya hydrolyse. Amatsinda yabanjirije hydrolyse afite ubucucike buhebuje cyane, butuma PAS nyinshi itemerwa kuruta alum.Mukiziganga cyane umwanda ukomeye washizwe nabi mumazi.

PAC ifite ibyiza bikurikira kuri aluminiyumu sulfate

1. Ikora cyane cyane. Nk'itegeko ry'igikumwe, Dose ya PAC ni kimwe cya gatatu cya Dose asabwa kuri Alum.

2. Yasize Aluminiyumu idasigaye mumazi yavuwe

3. Itanga sludge

4. Ikora hejuru ya PH nini

Hariho ubwoko bwinshi bwabakundwa, kandi iyi ngingo itangiza inshuro ebyiri. Mugihe uhisemo coagulant, ugomba gusuzuma ubuziranenge bwo kuvura kandi wingengo yimari yawe. Nizere ko ufite uburambe bwiza bwo kuvura amazi. Nkumuvuza utanga amazi utanga uburambe bwimyaka 28. Nishimiye gukemura ibibazo byawe byose (kubyerekeye imiti yo gutunganya amazi).
