(2) Maitiro ekushanda: Shandisa pombi yemvura inotenderera kuchengetedza kudzvanywa kuri pa 2/3bar uye kutenderera nepombi yemvura. Mushure memaminitsi gumi nemashanu, vhura vheji yekudhonza uye bvisa paunenge uchitenderera.
(3) Tembiricha: tembiricha yemumba
(4) Nguva: Maminitsi gumi nemashanu
(5) Bvisa mvura yakasvibiswa yekuchenesa.

2. Lye kuchenesa
(1) Formula: Gadzirira yakachena kemikari reagent ye sodium hydrochloride, wedzera mvura inopisa (tembiricha isiri pasi pe70 ℃) kuita 1% (volume concentration) lye.
(2) Mashandiro ekushanda: Dzvanya nepombi kweasingasviki maminetsi makumi matatu, wozoburitsa.
(3) Tembiricha: 70℃

(2) Maitiro ekushanda: Shandisa pombi yemvura inotenderera kuchengetedza kudzvanywa kuri pa 2/3bar kutenderera nepombi yemvura. Mushure memaminitsi makumi matatu, vhura valve yekudhonza uye bvisa paunenge uchitenderera.
(3) Tembiricha: tembiricha yemumba
(4) Nguva: Maminitsi gumi nemashanu
(5) Bvisa mvura yakasvibiswa yekuchenesa.

Passivation chirongwa
1. Acid passivation
(1) Fomula: Shandisa mvura yakasvibiswa uye makemikari yakachena nitric acid kugadzira 8% asidhi mhinduro.
(2) Maitiro ekushanda: Chengetedza pombi yemvura inotenderera pa 2/3bar kumanikidza uye kutenderera kwe60min. Mushure memaminitsi makumi matanhatu, wedzera sodium hydroxide yakakodzera kusvika iyo PH kukosha yakaenzana ne7, vhura vharafu yekudhonza, uye buritsa paunenge uchitenderera.
(3) Tembiricha: 49℃-52℃
(4) Nguva: 60 maminitsi
(5) Rega kubva pane passivation solution.

2. Mvura yakacheneswa sukurudza
(1) Fomula: Mvura yakasvibiswa patembiricha yekamuri.
(2) Maitiro ekushanda: Shandisa pombi yemvura inotenderera kuti uchengetedze kudzvinyirira pa 2 / 3bar kuti utenderere nepombi yemvura, vhura valve yekudhonza mushure memaminitsi mashanu, uye kubudisa paunenge uchitenderera.
(3) Tembiricha: tembiricha yemumba
(4) Nguva: Maminitsi mashanu
(5) Bvisa mvura yakasvibiswa yekuchenesa.

3. Shamba nemvura yakachena
(1) Fomula: Mvura yakasvibiswa patembiricha yekamuri.
(2) Mashandiro ekuita: Chengetedza pombi yemvura inotenderera iri pa2/3bar kudzvanywa uye tenderera nepombi yemvura kusvika iyo effluent pH isina kwayakarerekera.
(3) Tembiricha: tembiricha yemumba
(4) Nguva: asingasviki maminitsi makumi matatu
(5) Bvisa mvura yakasvibiswa yekuchenesa.

Ongorora: Paunenge uchichenesa uye uchipfuura, iyo sefa chikamu cheiyo chaiyo sefa inofanirwa kubviswa kudzivirira kukuvadzwa kune iyo sefa chinhu
