Ukusetyenziswa kwe-sodium sulfide kwimizi-mveliso kubandakanya iimeko ezinzima ngakumbi. Kwiiworkshops zokudaya, abasebenzi basebenza ngeesuti ezingamelani neekhemikhali kuba i-sodium sulfide ikhupha iigesi ezinobuthi kumaqondo obushushu aphezulu. Izityalo zonyango lwamanzi amdaka zihlala ziyisebenzisa ukukhawulezisa iintsimbi ezinzima, zifuna ulawulo olungqongqo lwesantya sokondla kunye nokuxhobisa imibhobho yokutya ngezixhobo ezichasene nekristali. Kwiindawo zokugaya amaphepha, apho isetyenziselwa ukuthambisa ipulp yomthi, indawo yokusebenza kufuneka igcinwe yomile, kunye neemathi ezichasene nokutyibilika phantsi kunye neempawu zesilumkiso ezinje ngokuthi "Akukho ziKomityi zaManzi eziVunyelweyo" ezixhonywe eludongeni.

Ukuthunyelwa ngqo ukusuka eQingdao Port, eTianjin Port, naseShanghai Port, kunye ne-logistics esebenzayo ye-sodium sulfide egubungela amazibuko amakhulu kwihlabathi liphela. Cofa apha ukuze ufumane iinkonzo ezisemgangathweni ophezulu.
