Incazelo emfushane:

Umshini wethu wokuhlunga ibhande lodaka uwumshini ohlanganisiwe wokuqinisa nokususa amanzi odaka. Usebenzisa ngendlela entsha umshini wokuqinisa udaka, ngaleyo ndlela ube nomthamo omkhulu wokucubungula kanye nesakhiwo esincane. Ngemuva kwalokho, izindleko zamaphrojekthi obunjiniyela bezakhiwo zingancishiswa kakhulu. Ngaphezu kwalokho, imishini yokucindezela udaka iyakwazi ukuzivumelanisa nezimo ezahlukene zodaka. Ingafinyelela umphumela omuhle wokwelapha, noma ngabe ukugcwala kodaka kungu-0.4% kuphela.

Ngemva kwezikhathi zokugoba kanye nokucindezela, i-slurry ihanjiswa ebhandeni elinezimbobo ukuze iqine futhi isuse amanzi adonsela phansi. Inani elikhulu lamanzi akhululekile lihlukaniswa ngamandla adonsela phansi, bese kwakheka izinto eziqinile ze-slurry. Ngemva kwalokho, i-slurry ihlanganiswa phakathi kwamabhande amabili acindezelwe ukuze idlule endaweni yokucindezela enomumo we-wedge, indawo yokucindezela okuphansi, kanye nendawo yokucindezela okuphezulu. Ikhishwa isinyathelo ngesinyathelo, ukuze kwandiswe ukuhlukaniswa kwe-sludge namanzi. Ekugcineni, ikhekhe lokuhlunga liyakhiwa futhi likhishwe.
