ʻO ka wai hoʻomaʻemaʻe e pili ana i ka H2O me ka haumia ʻole, ʻo ia ka wai maʻemaʻe a i ʻole ka wai maʻemaʻe no ka pōkole.He wai maʻemaʻe a maʻemaʻe me ka haumia ʻole a i ʻole bacteria.Hana ʻia ia me ka wai i kūpono i nā kūlana maʻemaʻe o ka wai inu home e ke ʻano electrodialyzer raw, ke ʻano hoʻololi ion, ke ʻano osmosis reverse, ke ʻano distillation, a me nā ʻano hana kūpono ʻē aʻe.Hiki iā ʻoe ke inu pololei.
I nā makahiki i hala iho nei, me ka hoʻomaikaʻi mau ʻana o ka pae moʻomeheu o ka poʻe, ke kūlana ola, a me ka pae ʻai, ua hoʻololi ka poʻe mai nā koi ola maʻamau e like me ka meaʻai a me nā lole i ka ʻimi ʻana i nā huahana ola kūlohelohe a olakino.No ka wai inu koʻikoʻi i ke ola o nā kānaka, ʻike maopopo ʻia ka hana.I kēia manawa, ua hōʻea ka mākeke o ka wai inu i ka ʻoihana meaʻai a me nā mea inu i 40%.I waena o lākou, ʻoi aku ka nui o ka wai maʻemaʻe ma mua o 1/3.No laila, ʻo ke kaʻina holoʻokoʻa o ke kaʻina hana wai maʻemaʻe pono e nānā ʻia a nānā ʻia i ka manawa maoli i mea e hōʻoia ai i ka wai maʻemaʻe i kau ʻia ma ka mākeke he maʻemaʻe, maʻemaʻe a me nā huahana kūpono e pili ana i nā kānāwai a me nā lula pili.
Ma muli o ka haʻahaʻa haʻahaʻa o ka wai maʻemaʻe, ʻaʻole hiki ke ana i nā mika electromagnetic maʻamau.
Ma waho aʻe o ka hoʻohana maʻamau electromagnetic flowmeters, Sinomeasure hiki ke hāʻawi i ka clamp-mounted turbine flowmeters a i ʻole ultrasonic flowmeters me ka ʻole o ka haki ʻana o ka paipu e like me nā pono o ka mea kūʻai aku no ke ana wai maʻemaʻe.
