Pili kēia selectivity o kēpau kēpau kēpau i nā kumu aʻe:
1. ʻO ka ʻoi aku ka uku o ka band ion, ʻoi aku ka maʻalahi o ka hoʻolaha ʻia e ka resion exchange anion. ʻO kahi laʻana, ʻoi aku ka maʻalahi o ka hoʻopili ʻia ʻana o nā ion ival ma mua o nā ion monovalent.
2. No nā ion me ka nui o ke koina, ʻoi aku ka maʻalahi o ka hoʻopili ʻia ʻana o nā ʻona me ka ʻōtoma nui.
3. Hoʻohālikelike ʻia me ka hopena dilute, maʻalahi nā ʻona base i ka hopena paʻa e hoʻolaha ʻia e ka resin. 'Lelo maʻamau, no ka H-type acid acid cation anion exchange resin, ke koho koho o nā ion i ka wai. No ka Oh ʻano ikaika anion kūkaʻi kēpau, ʻo ke koho koho o nā anion i ka wai ʻoi aku ka maikaʻi. ʻO kēia selectivity o ka anion exchange resin he mea pono loa no ke kālailai ʻana a me ka hoʻokaʻawale ʻana i ke kaʻina hana o ka hoʻomaʻemaʻe wai ʻana i ka wai.
Kaohi i ka maikaʻi o ka wai kuhi resin:
1. Turbidity o ka wai: i lalo AC ≤ 5mg / L, AC convective ≤ 2mg / L. Ion kēpau kēpau
2. mālamalama hana koena: chlorine manuahi ≤ 0.1mg / l.
3. Koi oxygen koi (COD) ≤ 1mg / L.
4. ʻImi hao: moe hui AC ≤ 0.3mg / l, moe moena AC ≤ 0.1mg / l.
Ma hope o 10-20 mau pule o ka hana, ua nānā ʻia ke kūlana haumia o ke kēpau exchange cation. Inā loaʻa kekahi haumia, pono e mālama ʻia i ka manawa kūpono.
