25 ibisubizo bisanzwe byikibazo cya tekinoroji ya osmose membrane (Igice cya 3)

13. Umwanda hamwe na colloid ni iki? Nigute dushobora gupima?

Iyo ibice byanduye hamwe na colloid bibaye muri sisitemu ya osose cyangwa sisitemu ya nanofiltration, irashobora kugira ingaruka zikomeye kubyara amazi ya membrane ndetse rimwe na rimwe bikagabanya umuvuduko wa desalalasiya. Ibimenyetso byambere byerekana ububi bwa colloidal ni ukongera itandukaniro ryumuvuduko wa sisitemu, kandi inkomoko yibice cyangwa colloide mumasoko y'amazi ya membrane atandukana ahantu hamwe, akenshi harimo za bagiteri, isuka, silikoni ya silicon, ibicuruzwa byangirika, nibindi. Byongeye kandi, dielectrics ya cationic polymeric irashobora kandi kwitwara hamwe na anionic scale inhibitor, kandi imvura yabyo irashobora kwanduza ibice bigize membrane. SDI15 ikoreshwa mugusuzuma uburyo bwo gukora nabi cyangwa kubanza kuvurwa mumazi. Nyamuneka reba intangiriro irambuye mubice bijyanye.

14. Igihe kingana iki cyemewe cyo gufunga nta sisitemu ihindagurika?

Niba sisitemu ikoresha ibipimo byangiza, mugihe ubushyuhe bwamazi buri hagati ya 20-38 ℃, bifata amasaha agera kuri 4; Hafi yamasaha 8 munsi ya 20 ℃; Niba sisitemu idakoresha ibipimo byerekana, bizatwara umunsi 1.

15. Nigute dushobora gukoresha ingufu za sisitemu ya membrane?

Ingufu nke zikoreshwa muri membrane zirahagije, ariko twakagombye kumenya ko igipimo cyacyo cyo hasi kiri munsi yikintu gisanzwe.

Irashobora kunyura mu bwisanzure bwa microfiltration membrane, ikoreshwa mugukuraho bagiteri, micro flocs, cyangwa ibintu byose byahagaritswe (TSS). Umuvuduko usanzwe kumpande zombi za membrane ni 1-3 bar

16.Ushobora guhindura osmose sisitemu y'amazi meza akenshi gutangira no guhagarara?

Sisitemu ya membrane yashizweho ishingiye kubikorwa bikomeza, ariko mubikorwa nyabyo, hazajya habaho inshuro runaka yo gutangira no guhagarika. Iyo sisitemu ya membrane ihagaritswe, birakenewe gukoresha amazi yakozwe cyangwa yabanje gutunganyirizwa amazi yujuje ibyangombwa kugirango umuvuduko muke usimburwe n’amazi menshi yibanze cyane arimo ibipimo byangiza biva mu bice bigize membrane. Hagomba kandi gufatwa ingamba zo gukumira amazi muri sisitemu no kwinjiza umwuka, nkaho ibice bitemba bikuma, bishobora kuviramo gutakaza bidasubirwaho umusaruro w’amazi. Niba guhagarika bitarenze amasaha 24, nta mpamvu yo gufata ingamba zo gukumira mikorobe. Ariko niba igihe cyo guhagarika kirenze amabwiriza yavuzwe haruguru, amazi akingira agomba gukoreshwa mukubungabunga sisitemu cyangwa guhanagura igihe cya sisitemu.

17.Ni gute ushobora kumenya icyerekezo cyo gushyiramo impeta y'amazi yumunyu ku bice bigize membrane?

Impeta y'amazi yumunyu kuri membrane isabwa gushyirwaho kumpera yimbere yikintu, gufungura bikareba icyerekezo cyinjira. Iyo icyombo cyumuvuduko cyuzuyemo amazi, gufungura kwayo (umunwa wiminwa) bizakomeza gufungura, bifunga burundu urujya n'uruza rw'amazi kuva muri membrane kugeza kurukuta rw'imbere rw'ubwato.

18.Ni gute wakuramo silikoni mumazi?

Silicon mumazi ibaho muburyo bubiri: silicon ikora (monomeric silicon) na silicon siloidal (polysilicon): silikoni ya colloidal ntabwo ifite ibiranga ion, ariko ifite igipimo kinini. Silicon silicon irashobora guhagarikwa nuburyo bwiza bwo kuyungurura umubiri, nka osose ihindagurika, kandi ibirimo amazi birashobora kugabanuka hifashishijwe ikoranabuhanga rya coagulation, nkibigega bisobanura coagulation. Nyamara, tekinoroji yo gutandukana ishingiye kubiranga ion yishyurwa, nkibikoresho byo guhanahana ion hamwe nuburyo bukomeza bwa electrodeionisation (CDI), bifite imbaraga nke mukurandura silicon.

Ingano ya silikoni ikora ni ntoya cyane ugereranije na silikoni ya silikoni, bityo rero tekinoroji nyinshi yo kuyungurura umubiri nko gusobanura coagulation, kuyungurura, hamwe no guhinduranya ikirere ntishobora gukuraho silikoni ikora. Inzira zishobora gukuraho neza silikoni ikora harimo guhinduranya osmose, guhana ion, hamwe na electrodeionisation ikomeza.
