Kuzamuraisambaza, ugomba kubanza kuzamura amazi. Mu gikorwa cyose cyo korora isambaza, kugenzura ubwiza bw'amazi ni ingenzi cyane. Kongeramo no guhindura amazi ni bumwe mu buryo bworoshye bwo kugenzura ubwiza bw'amazi. Ese ikidendezi cy'isambaza kigomba guhindura amazi? Hari abantu bavuga ko isambaza zigoranye cyane. Guhindura imigongo kugira ngo zitere isambaza ku gishishwa bikunze gutuma umubiri wazo ucika intege kandi bikunze kurwara indwara. Abandi bavuga ko bidashoboka kudahindura amazi. Nyuma y'igihe kirekire cyo korora, ubwiza bw'amazi burahinduka, bityo tugomba guhindura amazi. Ese nahindura amazi mu gihe cyo korora isambaza? Cyangwa ni mu bihe ibihe amazi ashobora guhinduka kandi ni mu bihe ibihe amazi adashobora guhinduka?

 

Hagomba kubahirizwa ibintu bitanu kugira ngo hahindurwe amazi mu buryo bukwiye

1. Isambaza ntiziba ziri mu gihe cyo hejuru cyagutera amasasu, kandi umubiri wabo uba ufite intege nke muri iki cyiciro kugira ngo birinde imihangayiko ikomeye;

2. Isambaza zifite umubiri mwiza, zifite imbaraga, zirya cyane kandi nta ndwara zirwaye;

3. Isoko y'amazi irahamye, imiterere y'amazi yo ku nkombe z'inyanja ni myiza, ibipimo by'umubiri n'ibinyabutabire ni ibisanzwe, kandi nta tandukaniro rinini riri hagati y'umunyu n'ubushyuhe bw'amazi mu kidendezi cy'isambaza;

4. Amazi y'ikidendezi cya mbere afite uburumbuke runaka, kandi ibimera byo mu mazi birakomeye cyane;

5. Amazi yinjiramo ayungururwa n'urushundura rurerure kugira ngo hirindwe ko amafi yo mu gasozi atandukanye n'abanzi binjira mu kidendezi cy'isambaza.

Uburyo bwo kuvoma no guhindura amazi mu buryo bwa siyansi muri buri cyiciro

1) Igihe cyo kororoka hakiri kare. Muri rusange, amazi ni yo yongerwamo gusa nta mazi asukuye, ibyo bikaba bishobora kongera ubushyuhe bw'amazi mu gihe gito kandi bigatera ibinyabuzima bihagije by'ibishishwa n'ibimera by'ingirakamaro.

Mu kongeramo amazi, ashobora kuyungururwa hakoreshejwe ibice bibiri by'amadirishya, hamwe n'umuyoboro 60 w'imbere n'umuyoboro 80 w'inyuma, kugira ngo hirindwe ko ibinyabuzima by'umwanzi n'amagi y'amafi byinjira mu kidendezi cy'isambaza. Shyiramo amazi kuri cm 3-5 buri munsi. Nyuma y'iminsi 20-30, ubujyakuzimu bw'amazi bushobora kugera kuri metero 1.2-1.5 uvuye kuri cm 50-60 za mbere.

2) Kororoka mu gihe giciriritse. Muri rusange, iyo amazi arenze cm 10, ntabwo bikwiye guhindura agakoresho ko kuyungurura kugira ngo bikuremo imyanda buri munsi.

3) Intambwe ya nyuma yo kororoka. Kugira ngo hongerwe ogisijeni yashongeshejwe mu gice cyo hasi, amazi yo mu kidendezi agomba kugenzurwa kuri metero 1.2. Ariko, muri Nzeri, ubushyuhe bw'amazi bwatangiye kugabanuka buhoro buhoro, kandi uburebure bw'amazi bushobora kongerwa neza kugira ngo ubushyuhe bw'amazi bukomeze kuba budahinduka, ariko impinduka z'amazi za buri munsi ntizigomba kurenza cm 10.

Mu kongeramo no guhindura amazi, dushobora guhindura ingano y'umunyu n'intungamubiri mu mazi yo mu kidendezi cy'isambaza, kugenzura ubucucike bw'ibimera bigizwe n'uturemangingo duto, guhindura ubuziranenge, no kongera ingano ya ogisijeni yashongeshejwe mu mazi yo mu kidendezi cy'isambaza. Mu gihe cy'ubushyuhe bwinshi, guhindura amazi bishobora gukonja. Mu kongeramo no guhindura amazi, pH y'amazi yo mu kidendezi cy'isambaza ishobora guhagarara neza kandi ingano y'ibintu byangiza nka hydrogen sulfide na azote ya ammonia ishobora kugabanuka, kugira ngo habeho ahantu heza ho gutura hatuma isambaza zikura.
