Hōʻike kēia i ka piʻi ʻana o ka pinepine a me ka ikaika o nā maloʻo a me nā kahe nui e like me ka awelika o ka mahana, no laila e waiho ana i nā haneli miliona o ka poʻe i ka pilikia no ka nele o ka wai maʻemaʻe.Ke manaʻo nei nā kūlanakauhale e like me Cape Town i ka ikaika piha o kēia mau hopena.
Ua manaʻo ʻia ʻo 2018 ka lā i hoʻopau ai ʻo Cape Town i kāna mau paʻi, ka lā mua loa o ka honua Zero.Ua alo ka poʻe kamaʻāina me ka manaʻolana o ka laina laina no nā hola ma nā paipu kū no ka loaʻa ʻana o kā lākou ʻai palena ʻole i kēlā me kēia lā he 25 lita i ka lā, no ka mea e hōʻole ʻia ke komo ʻana o ka lehulehu i ka wai i mua o ka maloʻo nui.ʻO kekahi mau kūlanakauhale nui a ʻoi aku ka nui o nā kūlanakauhale i ʻike ʻia e kokoke ana i ko lākou lā zero i nā makahiki e hiki mai ana
Eia naʻe, ke hana nei nā ʻepekema a me nā mea noiʻi i nā ʻano like ʻole o ka hana ʻana i ka wai hou mai nā ʻōnaehana liʻiliʻi a i nā ʻōnaehana kalepa a me nā ʻoihana.ʻO nā ʻōnaehana desalination maʻamau i hoʻohana ʻia i kēia manawa, ʻo ia nā kikowaena desalination thermal a me nā ʻōnaehana membrane.Hoʻohana ka ʻōnaehana wela i ka wela.ʻOiai ʻoi aku ka pipiʻi o nā ʻōnaehana boiler a koi i ka nui o nā kumu ikehu kumu kūʻai, ua hoʻololi nui kēia ʻano i ka honua i ka hana ʻana i ka wai maʻemaʻe.ʻO nā ʻōnaehana membrane, ma ka ʻaoʻao ʻē aʻe, ʻaʻole koi i nā mīkini paʻakikī.Me ka hoʻohana ʻana i ke kaomi a me kahi ʻano membrane kūikawā me kahi pepa permeable e hiki ai i ka wai maʻemaʻe ke hele i loko.Ma kēia ala, ʻoi aku ka wikiwiki o ka hana ʻana i ka wai maʻemaʻe.
Ua pilikia nā kūlanakauhale a puni ka honua i ka palekana o ka wai.ʻO ka hoʻololi ʻana i ke ea ke hoʻonui nei i nā mahana awelika a me nā wā maloʻo mau.Ke piʻi nei ke koi ma lalo o kēia mau kūlana, akā ʻo ka ua lohi a ʻaʻole i loaʻa i ka wā e hōʻemi ana i ka lako, no laila ke kau nei i ke koʻikoʻi nui i nā kumuwaiwai.ʻO kēia hemahema o ka wai maʻemaʻe i nā kūlanakauhale e hiki ai ke hōʻea i kāna lā Zero.ʻO ka lā Zero kahi manawa i manaʻo ʻia kahi i hiki ʻole ai i ke kūlanakauhale a i ʻole ka ʻāina ke hoʻolako i kona wahi noho me ka wai hou.Hoʻopili ʻia ka pōʻaiapili hydrologic me nā loli i ka mahana o ka lewa a me ke koena radiation, ʻo ia hoʻi ka hopena o ka piʻi ʻana o ka wela i ka nui o ka evaporation a me ka piʻi ʻana o ka ua wai.
At HUNA, haʻaheo mākou ʻo kekahi o nā ʻoihana alakaʻi e hana ana i ka hakakā ʻana i ka hōʻailona Day Zero no nā wahi he nui o ka honua e pilikia ana i ka nele o ka wai.Ke hana nei kā mākou hui noiʻi i ka hana ʻana i nā membrane kiʻekiʻe e koi ana i ka ikehu liʻiliʻi e ʻohi i ka wai inu hou.Paipai mākou i ka honua e mālama nui i ka waiwai makamae a hui lima a kaua aku iā Day Zero a puni ka honua.
