High pono decolorizing flocculant noi hihia

1 Wai ʻino

ʻO ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻōpala i loaʻa nā mea hoʻonaninani a me nā mea hoʻoheheʻe ʻia, paʻakikī ka mālama ʻana i nā ʻano hana wai ʻino ʻē aʻe, ʻo ka nui o ka wai he 3000 tons / lā.

2 Kaʻina hana

Ma hope o ka mālama olaola ʻana o ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻino → hoʻohui i ka flocculant decolorizing maikaʻi → hoʻohui i ka polyaluminum chloride (PAC), hoʻohui i ka polyacrylamide (PAM) → ka lele ʻana o ka ea a i ʻole ka ua → effluent

3 ʻIkepili Noi

ʻO ke ʻano o ka mea hoʻopau kala: 40-100 PPM

ʻO ka helu PAC: 150 PPM

PAM helu: 1 PPM

Ka wai ʻōpala

COD: 600mg/l

Kala: 40-50 manawa

4 Nā hualoaʻa

A. He hopena maikaʻi ka mea decolorizing i ka wehe ʻana i ke kala, ʻoi aku ka ʻulaʻula, a hiki i ka wai ʻino ke hoʻokō i nā kūlana hoʻokuʻu ʻāina ma hope o ka mālama ʻana.

b. I mea e hōʻemi ai i nā kumukūʻai lapaʻau ma nā noi kūpono, hiki ke hoʻohui ʻia ʻo PAC a me PAM e like me ka degere pollution o ka wai ʻino.
