1. Media kānana mea maoli
1). Ke one quartz
- ʻO ka mea nui ʻo ka silicon dioxide (SiO₂), me ka paʻakikī kiʻekiʻe (Mohs hardness 7) a me ka paʻa kemika ikaika. Hoʻohana nui ʻia ia i nā papa kānana wai.
- Nā mea kiko'ī maʻamau: 0.5-1.2mm (ka kānana koʻikoʻi), 0.3-0.5mm (ka kānana maikaʻi), e nānā i ka "Standard for Quartz Sand Filter Media for Water Treatment" (CJ/T 43-2005).
- Nā hemahema: kiʻekiʻe kiʻekiʻe (2.65g/cm³), kiʻekiʻe ka holoi ʻana i ka ikehu.
2). Anthracite
- He kiʻekiʻe ka porosity e like me 50%-60%, me ka mana adsorption ikaika, a hoʻohana pinepine ʻia me ke one quartz e hana i kahi pahu kānana papalua.
- Ka nui o ka nui o nā ʻāpana: 0.8-1.8mm, mānoanoa 1.4-1.6g/cm³ (ʻoi aku ka māmā ma mua o ke one quartz, hiki ke hoʻemi i ke kaomi holoi hope).
3). Zeolite
- Mea hoʻololi ion exchange maoli, me ka hopena adsorption nui ma ka naikokene amonia a me nā metala kaumaha, kūpono no ka mālama ʻana i ka wai ʻino.
2. Mea kānana mea polymer synthetic
1). Polypropylene (PP) fiber
- Acid and alkali resistant (pH 1-14), anti-microbial corrosion, i hana ʻia i ʻeke kānana a i ʻole nā mea kānana, i hoʻohana ʻia ma ka ʻoihana kemika a me ka ʻoihana meaʻai.
- Pololei kānana: 1-100μm (hoʻololi ʻia e like me ka nui o ka ulana ʻana).
2). Polyester (PET) - lole i ulana ole ia
- Ka ikaika kiʻekiʻe a me ka hikiwawe o ka ea, hoʻohana mau ʻia i ka kānana ea (e like me ka kānana HEPA).
3). Polyethylene (PE) mea kānana sintered
- Hoʻokumu ʻia ka microporous e ka -sintering wela, me ka pololei a hiki i ka 0.1μm, hoʻohana ʻia no ka hoʻomākaukau ʻana i ka wai ultrapure.
3. Metala a me ka ipu kānana media
1). Mesh uwea kila kila
- Ke kumu hoʻohālike 304/316L, pale wela kiʻekiʻe ( I lalo a i ʻole like me 800 degere ), ka nui o ka puka 20-200 mesh, hoʻohana ʻia i loko o ka ʻoihana ʻaila a me nā lāʻau lapaʻau.
2). ʻO nā seramika poha
- Made of alumina or silicon carbide, with a compressive strength of >10MPa, kūpono no ke kiʻekiʻe-e hoʻoneʻe ʻia i ka lepo lepo (e like me nā mea kanu ʻōpala).
4. Nā mea hana kūikawā
1). Kalapona ho'ā
- 500-1500m²/g (e nānā i ka "Coal Granular Activated Carbon Standard" GB/T 7701.1-2008), hiki ke hoʻopili i nā mea ola a me ke koena chlorine.
2). Media kānana mākēneki
- The surface is loaded with Fe₃O₄, and the metal particles in oily wastewater are quickly separated by magnetic field, with a recovery rate of >90%.
Manaʻo hoʻonui:
- Hiki ke noʻonoʻo i ka kānana kino a me ka adsorption kemika;
- Aia nā mea e puka mai ana e like me nā membrane kānana graphene (ka pono kānana 0.001μm) ma ke kahua hoʻokolohua a he ʻano pipiʻi.
