ʻO ka hana kānana ʻana o ka pia huki me ka membrane polyvinylidene fluoride a me ka hopena o nā hua bacteria kānana

ʻO ka pia Draft, i ʻike ʻia ʻo ka pia draft, he ʻano o ka aseptic kānana a me ka aseptic hoʻopiha pia me ka ʻole o ka pasteurization a i ʻole ka disinfection koke.Loaʻa iā ia nā amino acids waiwai, nā carbohydrates, nā paʻakai inorganic, nā ʻano huaora a me nā ʻano enzyme ikaika, hiki ke hoʻonui i ka ʻai a hoʻoikaika i ka ʻai.

No ka pia kiʻekiʻe ka Draft Beer.ʻO ka kānana a me ka sterilization ka loulou nui o ka hana.Hiki i ka ʻenehana hoʻokaʻawale membrane ke hoʻopaʻa loa i nā ʻano meaʻai āpau i ka meaʻai me ka hoʻohana ʻana i ke kumu kānana.Ke hoʻohana ʻia i ka hana ʻana i ka pia draft, ʻoi aku ka maʻalahi o ka waiʻona i hana ʻia, ʻoi aku ka lōʻihi o ka paʻa ʻana o ka bubble, a ʻoi aku ka nui o ka protein sensitive a me ke anuanu turbidity index ma mua o 30% haʻahaʻa ma mua o ka kānana o ka honua tausani.Eia nō naʻe, ʻo ka pollution membrane hiki ʻole ke hoʻopilikia nui i ka hana kānana, a ʻo ka pae paʻa equilibrium pass wale nō ma kahi o 10L/(m²/h), e kaupalena ana i ka noi ʻana o ka ʻenehana kānana membrane i ka hana pia.

E koho hydrophilic PVDF membrane filtration draft pia, ua aʻo i ka PVDF microfiltration membrane kānana kānana bacteria o escherichia coli bacteria hoʻokuʻu hana a me ka hoʻolālā membrane, membrane puka, ka pilina ma waena o nā hale ʻelua i nānā ʻia nā microfiltration membranes pono e hoʻohana no ka kānana sterilization hopena o ka kānana pia, Membrane flux hoʻololi a me nā ʻano like ʻole o ka hopena holoi holoi qing, a pēlā aku, hāʻawi i kahi kuhikuhi no ka noi hou aku.

ʻO ke ʻano hoʻokolohua

Hoʻoholo ʻia ka puʻupuʻu pore o ka membrane PVDF e ka mea hoʻoheheʻe i hana ponoʻī iā ia iho - velocity method pore size distribution tester.Hoʻokiʻoki ʻia ka diaphragm pōʻai mai ka kiʻiʻoniʻoni maloʻo, hoʻomoʻi ʻia i loko o hoʻokahi tausani o ka wai hoʻomaʻemaʻe a hiki i ka translucent, wehe ʻia a maloʻo me ka pepa kānana, a laila hohola ma luna o ka mea ʻike no ka ʻike.He isopropanol ka wai hooluu, a he nitrogen ke kumu kaomi.

No ke ana ʻana Angle contact, ua ʻoki ʻia kahi diaphragm square 2cmx2cm, hoʻopaʻa ʻia ma ka paheʻe, a kau ʻia ma ka papa hāpana no ka ʻike.Ua hoʻopaʻa ʻia ke kihi pili o nā kulu wai mai ka ʻili o ke kiʻiʻoniʻoni e nalowale loa.

Ua hoʻopili ʻia ka ʻili o luna a me lalo o nā laʻana kiʻiʻoniʻoni i hoʻopili ʻia i ka papa ʻaina me ka hoʻopili conductive.Ua paʻa nā ʻāpana keʻa i ka hau a kinai ʻia me ka naikokene wai, a ua hoʻopili ʻia nā ʻāpana keʻa i ka papa ʻaina me ka hoʻopili conductive.Ua hoʻopaʻa ʻia nā laʻana i loko o ka ʻawaʻawa a kau ʻia ma luna o ke kahua microscope electron no ka nānā ʻana.

Helu microbial E. coli helu: E lawe i ka hāpana e hoʻāʻo ʻia, e nānā iā GB4789.3-2010 no ka hoʻāʻo ʻana.ʻO ka helu helu o nā koina o ka pia huki: Ua lawe ʻia nā ʻāpana pia ma mua a ma hope o ka kānana ʻana a hoʻāʻo ʻia e like me GB4789.2-2010.Ka helu hū: E lawe i nā laʻana pia ma mua a ma hope o ka kānana ʻana, e nānā iā GB4789.15
