Pūnaehana Reverse Osmosis Lapaʻau

Hoʻolauna pōkole:

ʻO ka Reverse osmosis kahi ʻenehana hoʻokaʻawale membrane i hoʻomohala ʻia i ka makahiki 1980, kahi e hoʻohana nui ai i ke kumu semipermeable membrane, e noi ana i ke kaomi i ka hopena concentrated i kahi kaʻina osmosis, a laila e hoʻopau i ke kahe osmotic maoli. ʻO ka hopena, hoʻomaka ka kahe ʻana o ka wai mai ka ʻoi aku ka paʻa a hiki i ka hopena liʻiliʻi. He kūpono ʻo RO no nā wahi paʻakai kiʻekiʻe o ka wai maka a hoʻopau pono i nā ʻano paʻakai āpau a me nā haumia i ka wai.

Nā hiʻohiʻona:

ʻO ka wai wai RO, 1 wai wai RO, 2 RO wai wai a me EDI wai wai i lako me ka mahana, conductivity a me ke kahe, hiki ke nānā i nā ʻikepili hana āpau i ka manawa maoli.

Hāʻawi ʻia ka puka wai o ka pā wai maka, ka paila kiʻekiʻe kiʻekiʻe a me ka pā kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe i hāʻawi ʻia me nā mea pale e pale ai i ka hoʻoheheʻe anhydrous.

Hoʻonohonoho ʻia ka pale kaomi kiʻekiʻe ma ka puka wai o ka paila kiʻekiʻe kiʻekiʻe a me ka pā kiʻekiʻe kiʻekiʻe.

ʻO ka hoʻokuʻu wai koʻikoʻi ʻo EDI he kī haʻahaʻa haʻahaʻa.

ʻO ka wai maka, 1 RO wai wai, 2 RO wai wai a me EDI hana wai i loaʻa i ka ʻike conductivity pūnaewele, hiki ke ʻike i ka conductivity hana wai i ka manawa maoli. Ke kūpono ʻole ka conductivity hana wai, ʻaʻole ia e komo i ka ʻāpana aʻe.

Hoʻonohonoho ʻia ka hāmeʻa dosing NaOH i mua o RO e hoʻomaikaʻi i ka waiwai pH o ka wai, i hiki ke hoʻololi ʻia ka CO2 i HCO3- a me CO32- a laila wehe ʻia e ka membrane RO. (7.5-8.5)

Ua hoʻonoho ʻia ke awa i mālama ʻia ʻo TOC ma ka ʻaoʻao hana wai EDI.

Hoʻokaʻawale ʻia ka ʻōnaehana me ka ʻōnaehana hoʻomaʻemaʻe ʻakomi pūnaewele RO/EDI.
