Aluminum sulfate ma ke ʻano he coagulant i ka mālama wai ʻino

I kēia mau lā, nui nā mea kūʻai aku i nā koi kiʻekiʻe a kiʻekiʻe no ka alumini sulfate, no laila ua hana kā mākou hui i kahi kipa hoʻi i kekahi mau mea kūʻai.Ua ʻike mākou ʻoiai aia nā ʻōlelo aʻoaʻo, ʻaʻole maopopo i kekahi poʻe, a ke nānā ʻole nei lākou i kekahi mau mea e pono ke nānā ʻia.I kēia lā, e kūkākūkā ka mea hoʻoponopono i ka alumini sulfate ma ke ʻano he coagulant me ʻoe.

ʻO ka alumini sulfate wale nō ka mea kūpono no ka nui o ka waikawa, hiki ke hoʻohana ʻia ka hao-noa alumini sulfate no ka hoʻonui ʻana i nā wahi acidic a me ke kū ʻole, ua nāwaliwali loa ka ʻino o ka ʻōnaehana, a e maʻalahi ka mālama ʻana i ka wai keʻokeʻo;Hiki ke hoʻohana ʻia ka polyaluminum chloride i nā pae kūʻokoʻa a i ʻole ka alkaline e mālama i kahi uku kūpono kiʻekiʻe, ma kahi o ka hoʻokumu ʻana i ka Al(OH)3 precipitates e like me kēia huahana, a ma muli o ka pre-hydrolysis o polyaluminum chloride, ka pH waiwai o ka ʻōnaehana. ʻaʻole e hāʻule haʻahaʻa loa.

Paʻa ka alumini sulfate i ka ea.I ka 86.5, lilo kekahi hapa o ka wai o ka crystallization, a i ka 250, pau ka wai o ka crystallization.Ke hoʻomāhana ʻia, hoʻonui nui ʻia a lilo i spongy.Ke puhi ʻia ka ʻulaʻula, ua wāwahi ʻia i loko o ka sulfur trioxide a me ka alumini oxide.ʻO ke anā i ka wā e pili ana ka haʻahaʻa haʻahaʻa ma kahi o 25% haʻahaʻa.ʻO nā paʻakai kumu hiki ʻole ke hoʻoheheʻe ʻia ma hope o ka hoʻolapalapa lōʻihi.Eia kekahi, hui pū ʻia me ka hopena lapaʻau o ka wai alumini sulfate ma ka wai ʻōpala turbid, hiki i ka polyaluminum chloride ke hoʻokō i ka hopena o ka wehe ʻana i ka turbidity, a me ka wikiwiki i ka manawa e hoʻokō ai i ka hopena o ka wehe ʻana i ka turbidity, akā no ka mea he kiʻekiʻe ke kumukūʻai pili a me ka ʻaʻole lōʻihi ka manawa no ka wehe ʻana i ka turbidity.Ke hoʻohālikelike ʻia me ka ferrous sulfate, ʻoi aku ka paʻakai o ka sludge i hana ʻia e ka paʻakai alumini, hiki ke hōʻemi nui i ke kumukūʻai mālama sludge.

ʻO ka hoʻolauna i luna e pili ana i ka alumini sulfate.Hiki ke ʻike ʻia ma luna aʻe nei he pololei ka hoʻohana ʻana i ka alumini sulfate ma ke ʻano he coagulant i ka mālama ʻana i ka wai ʻōpala turbid.Inā ʻaʻole maopopo iā ʻoe kekahi mea, e ʻoluʻolu e leka uila mai iā mākou.
