Electrocoagulation (EC) ni inzira ikoresha amashanyarazi kugirango ikureho umwanda. Harimo no gukoresha amashanyarazi ya dc kugirango ashongeshe electrode yigitambo, hanyuma ikarekura ion zicyuma zifata umwanda. Ubu buryo bumaze kumenyekana bitewe nuburyo bukora neza, ibidukikije byangiza ibidukikije, hamwe nuburyo bwinshi bwo gutunganya ubwoko bwamazi mabi.
Amahame ya Electrocoagulation
Muri electrocoagulation, umuyagankuba unyuzwa muri electrode yicyuma yibizwa mumazi mabi. Anode (electrode nziza) irashonga, ikarekura ibyuma nka aluminium cyangwa fer mumazi. Izi ion zicyuma zifata umwanda mumazi, zikora hydroxide idashonga yegeranya kandi irashobora gukurwaho byoroshye. Cathode (electrode itari nziza) itanga gaze ya hydrogène, ifasha mukureremba uduce duto twa coagile hejuru kugirango dusimbuke.
Inzira rusange irashobora kuvunagurwa muburyo bukurikira:
Electrolysis: amashanyarazi ya dc akoreshwa kuri electrode, bigatuma anode ishonga kandi ikarekura ion ibyuma.
Coagulation: Iyoni yicyuma yarekuwe itesha agaciro amafaranga yingingo zahagaritswe hamwe n’imyanda yanduye, bigatuma habaho igiteranyo kinini.
Flotation: Amazi ya gaze ya hydrogène yakozwe kuri cathode yometse kuri agregate, bigatuma areremba hejuru.
Gutandukana: Isuka ireremba ikurwaho no gusimbuka, mugihe umwanda watunganijwe ukusanyirizwa hasi.
Ibyiza bya DC Amashanyarazi muri Electrocoagulation
Gukora neza: amashanyarazi ya dc atuma igenzura neza kuri voltage na voltage ikoreshwa, guhuza iseswa rya electrode no kwemeza kwanduza neza ibyanduye.
Ubworoherane: Igenamigambi rya electrocoagulation ukoresheje amashanyarazi ya DC biroroshye cyane, bigizwe n'amashanyarazi, electrode, hamwe nicyumba cya reaction.
Ibidukikije byangiza ibidukikije: Bitandukanye na coagulation chimique, electrocoagulation ntabwo isaba kongeramo imiti yo hanze, bigabanya ibyago byo kwanduza kabiri.
Guhindagurika: EC irashobora kuvura ibintu byinshi byanduza, harimo ibyuma biremereye, ibinyabuzima, ibinyabuzima byahagaritswe, ndetse na virusi.
Gushyira mu bikorwa amashanyarazi mu gutunganya amazi mabi
Amazi y’inganda: Electrocoagulation ifite akamaro kanini mugutunganya amazi mabi yinganda arimo ibyuma biremereye, amarangi, amavuta, nibindi byangiza. Inganda nkimyenda, amashanyarazi, nubuvuzi bungukirwa nubushobozi bwa EC bwo gukuraho ibintu byuburozi no kugabanya ogisijeni ikomoka ku miti (COD).
Amazi y’amazi ya komine: EC irashobora gukoreshwa nkuburyo bwambere cyangwa ubwa kabiri bwo gutunganya amazi y’amazi ya komine, bifasha gukuraho ibintu byahagaritswe, fosifeti, na virusi. Itezimbere ubwiza bwamazi yatunganijwe, bigatuma ikwirakwizwa cyangwa kongera gukoreshwa.
Amazi y’ubuhinzi: EC ishoboye kuvura amazi y’ubuhinzi arimo imiti yica udukoko, ifumbire, n’ibinyabuzima. Iyi porogaramu ifasha mukugabanya ingaruka zibikorwa byubuhinzi kumazi hafi.
Gutunganya amazi yimvura: EC irashobora gukoreshwa mumazi yimvura kugirango ikureho imyanda, ibyuma biremereye, nibindi bihumanya, bikabuza kwinjira mumazi asanzwe.
Ibipimo bikoreshwa hamwe na Optimisation
Imikorere ya electrocoagulation iterwa nibintu byinshi bikora, harimo:
Ubucucike bwa none: Ingano ikoreshwa kuri buri gice cya electrode igira ingaruka ku gipimo cyo gusohora ibyuma bya ion hamwe nubushobozi rusange bwibikorwa. Ubucucike buri hejuru burashobora kongera uburyo bwo kuvura ariko burashobora no gutuma ukoresha ingufu nyinshi hamwe no kwambara electrode.
Ibikoresho bya electrode: Guhitamo ibikoresho bya electrode (mubisanzwe aluminium cyangwa fer) bigira ingaruka kumikorere no gukora neza. Ibikoresho bitandukanye byatoranijwe hashingiwe ku bihumanya byihariye biboneka mu mazi mabi.
pH: pH y'amazi mabi agira ingaruka kumashanyarazi no gukora hydroxide yicyuma. Urwego rwiza rwa pH rwemeza ko coagulation ikora neza kandi itajegajega.
Iboneza rya Electrode: Gutunganya no gutandukanya electrode bigira ingaruka ku ikwirakwizwa ryumuriro wamashanyarazi hamwe nuburyo bwo kuvura. Iboneza neza byongera umubano hagati yicyuma cyanduye nibihumanya.
Igihe cyo kubyitwaramo: Igihe cya electrocoagulation kigira ingaruka kurwego rwo gukuraho umwanda. Igihe gihagije cyo kubyitwaramo gikora coagulation yuzuye no gutandukanya umwanda.
Ibibazo hamwe nicyerekezo kizaza
Nubwo ibyiza byayo, amashanyarazi ahura nibibazo:
Ikoreshwa rya Electrode: Imiterere yigitambo cya anode iganisha ku kuyikoresha buhoro buhoro, bisaba gusimburwa cyangwa kuvugurura buri gihe.
Gukoresha Ingufu: Mugihe amashanyarazi ya DC yemerera kugenzura neza, birashobora gukoresha ingufu cyane cyane kubikorwa binini.
Imicungire yimyanda: Inzira ibyara ibicuruzwa bigomba gucungwa neza no kujugunywa, byiyongera kubikorwa byo gukora.
Ubushakashatsi n'iterambere bizaza bigamije gukemura ibyo bibazo na:
Kunoza ibikoresho bya electrode: Gutezimbere ibikoresho biramba kandi byiza bya electrode kugirango ugabanye ibyo ukoresha no kuzamura imikorere.
Gutezimbere Amashanyarazi: Gukoresha tekinoroji yo gutanga amashanyarazi agezweho, nka DC ya pulsed, kugirango ugabanye ingufu kandi unoze uburyo bwo kuvura.
Gutezimbere Gukoresha Amashanyarazi: Guhanga uburyo bushya bwo kugabanya imyanda no guha agaciro, nko guhindura ibishishwa mubikorwa byingirakamaro.
Mu gusoza, amashanyarazi ya DC afite uruhare runini mugukoresha amashanyarazi mugutunganya amazi mabi, bitanga igisubizo cyiza, cyangiza ibidukikije, kandi gihindagurika mugukuraho umwanda utandukanye. Hamwe niterambere rigenda ritera imbere hamwe nogutezimbere, amashanyarazi yiteguye kuba uburyo bwiza kandi burambye bwo gukemura ibibazo byo gutunganya amazi mabi ku isi.
