Whakamahinga
Ko tēnei hua te rauemi matua mō te whakakikorua hiko kore-cyanide. Ina hangaia hei otinga whakakikorua parahi kore-cyanide, he pai te kaha o te here ina whakakikorua tika i te paparanga parahi ki runga i te rino konutai. He maeneene te paninga, ā, he kanapa pai. Ko te horopeta o te hua me te ihirangi 60% he 100 - 120 ml/L. Ko te horopeta o te konukura whanariki he 15 - 20 g/L. Hei tāpiri, i mua i te whakakikorua hiko, rumakina ngā wāhanga whakakikorua ki roto i te otinga 1% - 2% o tēnei hua kia huri ai ngā wāhanga whakakikorua ki te āhua whakahohe. Mā te whakakikorua hiko i muri i tēnei taahiraa ka taea te whakapai ake i te pānga. Ko te waikawa Hydroxyethylidene diphosphonic (HEDP) he momo hou o te matū whakakikorua hiko kore-chlorine. Ka whakamahia hei matū matua mō te whakaū i te kounga o te wai i roto i te pūnaha wai whakamatao e rere ana, e mahi ana i te mahi aukati waikura me te aukati unahi. Ko tēnei hua tētahi o ngā matū maimoatanga wai waikawa polyphosphonic waro. Tērā atu anō ētahi momo hua o tēnei momo e hangaia ana i Haina, pērā i te waikawa amino trimethylene phosphonic (ATMP): [CH2PO(OH)2]3N, me te ethylenediamine tetra(methylene phosphonic acid) (EDTMP), me ētahi atu. I whakawhanakehia ngā waikawa polyphosphonic waro i te mutunga o te tekau tau atu i 1960, ā, i mōhiotia i te tekau tau atu i 1970. Nā te putanga mai o tēnei momo kaihoko maimoatanga wai i tino matatau ai te hangarau maimoatanga wai. Ki te whakatauritea ki ngā polyphosphates inorganic, he pai te pumau matū o ngā waikawa polyphosphonic waro, kāore e ngāwari ki te waikura, ka taea te tu atu i ngā pāmahana teitei, me iti te horopeta o te kaihoko, ā, he āhuatanga anō hoki o te aukati waikura me te aukati unahi. He momo aukati waikura cathodic ēnei, he momo aukati unahi kore-stoichiometric anō hoki. Ina whakamahia ngātahi me ētahi atu kaihoko maimoatanga wai, ka whakaatu i te pānga synergistic tino pai. He tino pai te kaha chelating mō te maha o ngā katote konganuku pērā i te konupūmā, te konupora, te parahi, me te konutea. He pai hoki te pānga whakakore i ngā tote kore-waro o ēnei konganuku, pērā i te CaSO4, CaCO3, MgSiO3, me ētahi atu. Nō reira, he whānuitia te whakamahinga o ēnei i roto i te hangarau maimoatanga wai. Ka whakamahia ngā matū whakapūmua hei ārai i te serine me te pyranose.
Te Tākai me te Tukunga
Te tākai: 25kg e ai ki ngā whakaritenga a te kiritaki.
Tukunga: nō ngā matū noa, ā, ka taea te tuku mā te tereina, te moana me te rangi.
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
