pH ọ nwere mmetụta na salination na ogologo ndụ nke membran osmosis na-agbanwe?

Dị ka isi usoro nzacha na akụrụngwa ọgwụgwọ mmiri, reverse osmosis akụrụngwa na-ekpebi ma uru pH nke mmiri mmiri na-abanye n'ime reverse osmosis membrane ga-emebi akpụkpọ ahụ. N'ikwu okwu n'ozuzu, a na-ejikarị ihe ndị mejupụtara akpụkpọ anụ mee ihe maka mgbanaka osmosis. Ọ bụrụ na uru pH dị n'ime oke a kapịrị ọnụ nke 2-11, mmebi na mmetụta nke uru pH na akpụkpọ ahụ n'onwe ya ga-adị ntakịrị.

N'ihe gbasara mmetụta nke pH na ọnụ ọgụgụ nkwụsị nke reverse osmosis membranes, a na-ekpebi site na njirimara nke ion dị iche iche na mmiri nke na-emetụta uru pH. Nke a bụ n'ihi acidity, decomposability, na ogo nke ụgwọ nke ions n'onwe ha, nke bụ ihe niile nwere ike ime ka mbelata nke ntanye nke akpụkpọ ahụ.

Enwere ike ịhụ na pH ka na-enwe mmetụta dị ukwuu na ọnụ ọgụgụ nkwụsị nke ụfọdụ adịghị ọcha. N'otu aka ahụ, ọ bụrụ na mwepụ nke CO2 site na reverse osmosis akpụkpọ anụ bụ efu na pH uru nke raw mmiri na-abawanye iji tọghata CO2 n'ime CO32-, reverse osmosis akpụkpọ anụ nwere ike nke ọma desalinate. Ma n'oge a, e kwesịrị ịkwụ ụgwọ nlebara anya pụrụ iche na nsogbu scaling nke reverse osmosis membrane.
