Gutunganya neza uburyo amazi yanduye akoreshwa mu kuvura indwara ya Anaerobic hakoreshejwe uburyo bwa TOC bwo kugenzura neza

Mu gutunganya amazi yanduye, kugenzura imitwaro y’ibinyabuzima, cyane cyane Total Organic Carbon (TOC), byabaye ingenzi cyane kugira ngo ibikorwa bikomeze gukora neza kandi neza. Ibi ni ukuri cyane cyane mu nganda zifite imyanda ihindagurika cyane, nk'urwego rw'ibiribwa n'ibinyobwa (F&B).

Muri iki kiganiro, Jens Neubauer na Christian Kuijlaars bo muri Veolia Water Technologies & Solutions baganira na AZoMaterials ku kamaro ko gukurikirana TOC n'uburyo iterambere mu ikoranabuhanga rya TOC riri guhindura inzira zo gutunganya amazi yanduye.

Kuki kugenzura imitwaro y’ibinyabuzima, cyane cyane Total Organic Carbon (TOC), ari ingenzi mu gutunganya amazi yanduye?
Jens: Mu mazi menshi yanduye, inyinshi mu bintu byanduye ni ibya kijyambere, kandi ibi ni ukuri cyane cyane ku rwego rwa F&B. Kubwibyo, inshingano nyamukuru y'uruganda rutunganya imyanda ni ugusenya ibi bintu bya kijyambere no kubikura mu mazi yanduye. Gukomeza ibikorwa ni ugutuma amazi yanduye yihuta kandi akarushaho gukora neza. Ibi bisaba gukurikirana buri gihe imiterere y'amazi yanduye kugira ngo hakemurwe vuba impinduka iyo ari yo yose, hagakorwa isuku ihagije nubwo hakiri igihe gito cyo kuyatunganya.

Uburyo gakondo bwo gupima imyanda y’ibinyabuzima mu mazi, nko gukenera ogisijeni mu binyabutabire (COD) n’ibizamini bya ogisijeni mu binyabutabire (BOD), biratinda cyane - bifata amasaha menshi kugeza ku minsi - bigatuma bidakwiye gukoreshwa mu buryo bugezweho kandi bwihuse bwo kuvura. COD yasabaga kandi ibinyabutabire by’uburozi, ibyo bikaba bidakenewe. Mu buryo bunyuranye, kugenzura imizigo y’ibinyabuzima hakoreshejwe isesengura rya TOC bifata iminota mike gusa kandi ntibikubiyemo ibinyabutabire by’uburozi. Birakwiriye cyane mu isesengura ry’imikorere kandi bitanga ibisubizo nyabyo. Uku guhinduka kugana ku gupima TOC kugaragarira kandi mu mahame aheruka ya EU yerekeye kugenzura imiyoboro y’amazi, aho gupima TOC ari bwo buryo bwiza kurusha ubundi. Icyemezo cya Komisiyo Ishyira mu Bikorwa (EU) 2016/902 cyashyizeho imyanzuro myiza iboneka (BAT) hakurikijwe Amabwiriza 2010/75/EU ku buryo busanzwe bwo gutunganya/gucunga amazi yanduye mu rwego rw’ibinyabutabire. Ibyemezo bya BAT byakurikiyeho bishobora no kurebwa kuri iyi ngingo.

Ni uruhe ruhare igenzura rya TOC rigira mu kubungabunga imikorere myiza n'imikorere myiza y'uburyo bwo gutunganya amazi yanduye?
Jens: Igenzura rya TOC ritanga amakuru y'ingirakamaro ku bijyanye no gushyira karuboni mu byiciro bitandukanye by'iyi gahunda.

Gukurikirana TOC mbere yo kuyivura hifashishijwe ibinyabuzima bituma ibasha kubona ibintu bihungabanya imiterere ya karuboni no kuyijyana mu bigega by’ubuhumekero uko bikenewe. Ibi bishobora kwirinda kurenza urugero rw’ibinyabuzima no kuyisubiza mu buryo nyuma, bigatuma uruganda rukora neza kandi mu buryo buhamye. Gupima TOC mbere na nyuma yo kuyishyira mu mwanya wayo bituma abayikora bagenzura uburyo bwo gupima karuboni binyuze mu kongeramo karuboni kugira ngo badapfa kwicisha inzara cyangwa ngo barye bagiteri nyinshi mu bigega by’umwuka cyangwa mu gihe cy’ubuhumekero.

Gukurikirana TOC bitanga amakuru ku rugero rwa karuboni aho iva ikagera no ku buryo ikurwamo neza. Gukurikirana TOC nyuma yo gucukurwa mu kirere bitanga ibipimo nyabyo bya karuboni irekurwa mu bidukikije kandi bikerekana ko imipaka yubahirizwa. Byongeye kandi, gukurikirana ibinyabuzima bitanga amakuru ku rugero rwa karuboni kugira ngo binoze uburyo bwo kuyitunganya mu rwego rwo kongera kuyikoresha kandi bishobora gufasha kunoza uburyo bwo kuyipima, kuyitunganya mbere yo kuyikuraho, no kuyipima mu buryo bwa ozone na UV.
