Impamvu Uturemangingo twa RO tw’inganda dutakaza imikorere - n'uburyo bwo gutuma turamba igihe kirekire

Abagizi ba nabi b'ingenzi: Impamvu imikorere igabanuka

Uduce twa RO tw’inganda duhora twibasirwa n’imyanda y’amazi yo mu nganda. Kugabanuka k’amazi asanzwe no kwangwa k’umunyu hafi ya byose bigaruka ku buryo butandukanye bwo mu mubiri no mu bya shimi.

Udukoko twa Colloidal na OrganicBirashoboka ko ari cyo kibazo gikunze kugaragara cyane mu mutwe. Uduce duto tw’ibinyabutabire n’ibintu karemano byirundanya ku buso bw’urukiramende, bigatera urwego rw’amazi abuza amazi gutembera. Ubushakashatsi ku mazi yanduye akomoka ku bimera by’amakara, ibiryo bizwiho kuba bigoye, bwerekana ko ibintu bihumanya ikirere—cyane cyane ibice bidafite aho bihuriye n’amazi n’ibintu bihumanya ikirere—ari byo bituma amazi agabanuka. Iyo ibi bintu karemano bifashe ku buso bwa polyamide, birema urufatiro rufatana rwo kongera kwanduza.

Gupima no Guhumanya Ibidukikijebibaho iyo umunyu ushongesha gato urenze urugero rw'umusaruro wayo mu mugezi uvanze. Karubone ya kalisiyumu na sulfate ya kalisiyumu ni byo bikunze kubangamira, ariko guhumanya silicon birushaho kugaragara nk'ikibazo gikomeye mu kongera gukoresha amazi yanduye mu nganda. Guhindura imiterere ya silica ku buso bw'urukiramende bishobora gutuma amazi yangirika adasubira inyuma kandi ni ikintu cy'ingenzi gituma uruvange rugera ku iherezo ry'ubuzima. Ibi ni ikibazo cyane cyane mu buryo bworoshye bwo kugarura ibidukikije aho silica iba yuzuye cyane.

Kwangirika kw'ibinyabutabire n'ingufuyibasira urwego rwa polyamide rw’ururabo ubwarwo. Chlorine, ikunze gukoreshwa mu gusukura imiti yo mu kirere, ni oxidizer ikomeye ishobora guca imigozi ya amide, igasenya burundu ubushobozi bwo kwanga umunyu. Itegeko ry’inganda—gukomeza ko chlorine idafite ubwikorezi iri munsi ya 0.1 ppm—ririho kubera iyi mpamvu nyayo.

Gupima ingaruka: Ikiguzi cyo guhumanya ikirere kiri hejuru

Ingaruka z’ubukungu ziterwa n’imyanda ni nyinshi. Isesengura ryerekana ko imyanda ikoreshwa mu ruhu ingana na 24% by’ikiguzi cy’imikorere muri sisitemu za RO. Ibi bigaragarira mu kongera ikoreshwa ry’ingufu (umuvuduko mwinshi w’ibiryo kugira ngo bikomeze kugenda), gusukura kenshi imiti (nabyo byangiza uruhererekane), ndetse no gusimbuza imburagihe.

Inyigo yo mu 2025 ku kuvura mbere y’amashanyarazi kuri RO igaragaza neza ingano y’ibintu biri mu kaga: igihe cyo kubaho cy’uturemangingo tuvura amazi akonjesha yo mu nganda cyarongerewe n’ihindagurika ry’ikirere.203%igihe hakoreshwaga uburyo bwo kuvura mbere y’uko hakorwa neza, bigabanyije ikiguzi cyo gukora ho 80%. Ibi bigaragaza ko imikorere y’urukiramende atari imikorere y’urukiramende ubwarwo gusa, ahubwo ari imiterere y’uburyo bwose bwo gukora.

Kwagura igihe cy'akazi: Ingamba zirimo ibice byinshi

Kugira ngo membrane irambe bisaba ingamba zihamye zitangira kera cyane mbere yuko amazi agera ku gice cy’urukiramende.

1. Uburyo bwo kuvura mbere y'uko ufatwa neza: Uburyo bwawe bwa mbere bwo kwirinda

Amakuru y’inganda agaragaza ko kugeza kuri 80% by’igabanuka ry’ururenda rw’umubiri mbere y’igihe bituruka ku kutagira uburyo bwo kuvura mbere y’igihe. Kuvura mbere y’igihe neza ntibishobora kuganirwaho.

• Ituma umuntu yoroha kandi igabanya ubukana bw'indwara:Gukuraho iyoni zo gukomera (Ca²⁺, Mg²⁺) binyuze mu guhinduranya iyoni cyangwa koroshya imiti bigabanya cyane ubushobozi bwo kwagura. Ubushakashatsi bumwe bwagaragaje ko koroshya bikuraho 79% bya kalisiyumu mu mazi yanduye ya shimi, bikarinda ikorwa ry’ibintu bidafite umwimerere bihumanya uturemangingo.
• Kumenya no Gushyiramo Oxidation:Karuboni ikora ku ruhu (GAC) ikuraho chlorine yigenga kandi ikanyunyuza ibintu bihumanya ikirere. Ozonation ishobora gusenya ibintu bifite uburemere bwinshi bwa molekile, bigatuma bidakunda gufata ku ruhu rw'ururabo. Hari ubwo, ubu buryo bwo kuvura bwagaragaye ko bwongera ubwiyongere bw'ururabo ku kigero cya 21.9%.
• Kugenzura SDI:Gukomeza gupima ubucucike bw'amazi (SDI) buri munsi ya 3 (kandi ntugire ngo birenge 5) ni ikintu cy'ingenzi. Kuyungurura amazi mu buryo bwa microfiltration cyangwa kuyungurura amazi mu buryo bwa ultrafiltration bishobora gutuma iyi ntego igerwaho.

2. Umurimo w'ubwenge: Kunoza imikorere no kuramba

Imiterere y'imikorere igomba gucungwa neza:

• Irinde ko umuntu arushaho kugira umuvuduko ukabije w'amaraso:Kurenza igitutu cy’urukiramende bigabanya imiterere y’urukiramende (compaction), bigabanya ku buryo budasubirwaho kwinjira.
• Gucunga Igipimo cyo Kugaruza:Gushyira imbaraga mu kugarura amazi menshi byongera ubwinshi bw'iyoni zikoreshwa mu mazi y'umugezi. Kunganya umusaruro w'amazi n'ingaruka zo kuyakoresha ni ngombwa.
• Guma uhora uhagaze neza:Ihindagurika rya pH, ubushyuhe, n'amazi bitera imbaraga za mekanike n'ibinyabutabire. Urusobe rwa polyamide rukora neza mu rugero rwa pH ruhamye rwa 6-8.

Umwanzuro

Kugabanuka k'imikorere y'urukiramende si ikintu kidasubirwaho; ni ingaruka z'imikoranire y'ibintu n'ibinyabutabire. Inzira yo kumara igihe kirekire mu kazi ni ukumenya "isano nke" - kuva kuri polymerization ya silica kugeza ku gufatana kw'ibinyabuzima - no kubikemura binyuze mu mikorere myiza ya sisitemu no mu miterere igezweho ya membrane. Mu guhuza uburyo bukomeye bwo kuvura mbere y'uko ruvugururwa, imikorere yitondewe, hamwe n'ikoranabuhanga ryacu risanzwe ridafite umwanda mwinshi, abakora mu nganda bashobora gusenya uruziga rwo gusimbuza kenshi no kugera ku mikorere yizewe kandi ihendutse mu gihe cy'imyaka myinshi.
