Polyamine PA ( EPI-DMA )
ʻO ka polyamine kahi mea hoʻohuihui i ʻoi aku ma mua o ʻelua mau pūʻulu amino. Hiki mai nā alkyl polyamines ma ke ʻano maoli, akā he synthetic kekahi. ʻAʻole waihoʻoluʻu nā Alkylpolyamine, hygroscopic, a hiki ke hoʻoheheʻe ʻia i ka wai. Ma kahi kokoke i ka pH neutral, aia lākou e like me nā derivatives ammonium.
ʻO ka polyamine kahi polymer cationic wai o nā paona molekala ʻē aʻe e hana maikaʻi ana ma ke ʻano he coagulant mua a me ka hoʻopiʻi neutralization agent i nā kaʻina hoʻokaʻawale wai-paʻa i nā ʻano ʻoihana like ʻole. Hoʻohana nui ʻia ia i ka hana ʻana i nā ʻano ʻoihana ʻoihana like ʻole a me ka mālama ʻana i ka wai.

Hoʻopili ʻia ʻo PA i loko o nā pahu plastik
Pono e hoʻopaʻa ʻia ka PA a mālama ʻia ma kahi maloʻo a me ka maʻalili. ʻAʻohe mea pōʻino, ʻaʻole hiki ke puhi a pahū ʻole. ʻAʻole ia he kemika weliweli.
Ke hoʻohana ʻia no ka mālama ʻana i nā wai kumu like ʻole a i ʻole ka wai ʻino, pili ka dosage i ka turbidity a me ka neʻe ʻana o ka wai. Hoʻokumu ʻia ka dosage ʻoi loa ma ka hoʻokolokolo. Pono e hoʻoholo maikaʻi ʻia ka wahi dosing a me ka wikiwiki o ka hui ʻana e hōʻoiaʻiʻo e hiki ke hui like ʻia ka kemika me nā mea ʻē aʻe i loko o ka wai a ʻaʻole hiki ke haki nā flocs. ʻOi aku ka maikaʻi o ka hoʻohana mau ʻana i ka huahana.
1. Ke hoʻohana wale ʻia, pono e hoʻoheheʻe ʻia i kahi ʻano o 0.05% -0.5% (ma muli o ka ʻike paʻa).
2. Ke hoʻohana ʻia e mālama i nā kumu like ʻole o ka wai a i ʻole ka wai ʻino, ua hoʻokumu ʻia ka dosage ma luna o ka turbidity a me ka neʻe ʻana o ka wai. Hoʻokumu ʻia ka dosage ʻoi loa ma ka hoʻokolokolo. Pono e hoʻoholo maikaʻi ʻia ka wahi dosing a me ka wikiwiki o ka hui ʻana e hōʻoiaʻiʻo e hiki ke hui like ʻia ka kemika me nā mea ʻē aʻe i loko o ka wai a ʻaʻole hiki ke haki nā flocs.
3. ʻOi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka huahana mau.
