1. Mai ke kumu kānana o ka ultrafiltration membrane wai hoʻomaʻemaʻe wai (UF) a me ka wai hoʻomaʻemaʻe RO, ʻelua kānana wai ma o ka membrane mea polymer.
Wehe i nā haumia mai ka wai.

2. Mai ka pono kānana o ka ultrafiltration membrane a me ka RO membrane, ʻokoʻa ka filtration pololei o nā mea ʻelua.ʻO ka pololei kānana o ka membrane ultrafiltration he 0.01 microns,
ʻO ka pololei kānana o ka membrane RO he 0.0001 microns.

Hiki i ka wai hoʻomaʻemaʻe i hoʻomaʻemaʻe ʻia e ka membrane ultrafiltration hiki ke wehe i nā mea haumia ʻino e like me ka sediment, rust, colloid a me nā microorganisms bacteria,
I ka manawa like, e mālama i nā minerala kumu a me nā ʻano mea i loko o ka wai.

Ma hope o ka holoi ʻana o ka membrane RO a me ka hoʻomaʻemaʻe ʻana, loaʻa ka wai maʻemaʻe me nā molekole wai wale nō i koe, ʻaʻole hiki ke hoʻopau wale i ka sediment, ʻōpala,
ʻO Colloids, bacteria a me nā mea ʻino ʻē aʻe, akā e wehe pū kekahi i nā pesticides, nā metala kaumaha, a pēlā aku. Olansi RO Water Purifier W4 (Reddot design awarded)
Aia kekahi ʻano kānana trace element ma hope o ka kānana ʻana o ka membrane RO, e hoʻohui ana i nā minerala a me nā mea trace e pono ai ke kino o ke kanaka.ʻO ka mea kūikawā loa he strontium.
Mālama ʻo Strontium i ka lawe ʻana o ka sodium a me ka calcium i ke kino.

3.Ultrafiltration membrane hoʻomaʻemaʻe wai hoʻohana maʻamau i ke kaomi o ka wai pila e hana i ka kānana me ka ʻole o ka uila.ʻO ka hoʻomaʻemaʻe wai RO no ka mea kiʻekiʻe loa ka pololei kānana,
ʻAʻole hiki ke hoʻokō ʻia ka kānana a me ka hoʻomaʻemaʻe ʻana me ka hoʻohana ʻana i ke kaomi wai o ka wai paipu ponoʻī, no laila pono e hoʻoikaika a hoʻoikaika ʻia e hoʻokō i ka hoʻomaʻemaʻe a me ka kānana ʻana i ka wai paipu.
Eia kekahi, hana maʻamau nā mea hoʻomaʻemaʻe wai RO i ka wai ʻino.Ma o ka hoʻomaikaʻi ʻana a me ka hoʻomaikaʻi ʻana o ka ʻenehana i nā makahiki i hala iho nei, ua hōʻemi ʻia ka ratio wai o nā mea hoʻomaʻemaʻe wai RO mai 3: 1 a i 2: 1 a i ʻole 1: 1.
