1. Abɔde mu nneɛma filter media .
1). Quartz anhwea .
- Ade titiriw a ɛwom ne silicon dioxide (SIO2), a ɛyɛ den kɛse (MoHS den 7) ne nnuru a ɛyɛ den a ɛyɛ den. Wɔde di dwuma kɛse wɔ nsu a wɔde yɛ aduru a wɔde yiyi mu no mu.
- Nsɛm a wɔtaa ka ho asɛm: 0.5-1.2mm (nsuo a ɛyɛ mmerɛw), 0.3-0.5mm (fitration a ɛyɛ fɛ), kyerɛ "gyinabea a wɔde quartz anhwea afiri a wɔde yɛ nsu ho adwuma" (CJ/T 43-2005).
- sintɔ: density a ɛkorɔn (2.65g/cm3), ahoɔden a wɔde di dwuma a ɛkorɔn a wɔde di dwuma.
2). Anthracite .
- Porosity no kɔ soro te sɛ 50%-60%, a ɛwɔ adsorption tumi a ɛyɛ den, na wɔtaa de quartz anhwea di dwuma de yɛ double-layer filter tank.
- Nneɛma nketenkete no kɛse: 0.8-1.8mm, density 1.4-1.6g/cm3 (ɛyɛ hare sen quartz anhwea, a ebetumi atew akyi hohoro nhyɛso so).
3). Zeolite .
- Abɔdeɛ mu ion sesa nneɛma, a ɛwɔ adsorption nkɛntɛnsoɔ kɛseɛ wɔ ammonia nitrogen ne heavy metals so, a ɛfata ma nsuo mu nsuo fĩ a wɔde yɛ adwuma.
2. Synthetic polymer ade a wɔde yiyi nneɛma mu .
1). Polypropylene (PP) fiber .
- acid ne alkali a ɛko tia (pH 1-14), anti-microbial corrosion, a wɔayɛ no filter bags anaasɛ filter elements, a wɔde di dwuma wɔ nnuru ne aduan nnwuma mu.
- filtration pɛpɛɛpɛ: 1-100μm (wɔayɛ no foforo sɛnea nwene density te).
2). Polyester (PET) non{2}}nkitahodi .
- Ahoɔden a ɛkorɔn ne mframa pa a ɛtumi fa mu, a wɔtaa de di dwuma wɔ mframa a wɔde yiyi mu (te sɛ HEPA filter).
3). Polyethylene (PE) a wɔde sintered ayɛ a wɔde yiyi nneɛma mu .
- Microporous structure a ɛnam soro-temperature sintering, a ɛyɛ pɛpɛɛpɛ a ɛkɔ soro kodu 0.1μm, a wɔde di dwuma ma ultrapure nsu ahosiesie.
3. Metal ne ceramic filter media .
1). Stainless dade hama mesh .
- Model 304/316L, ɔhyew a ɛkɔ soro (a ennu anaasɛ ɛne 800 digrii ), pore size range 20-200 mesh, a wɔde di dwuma wɔ petroleum ne nnuruyɛ nnwuma mu.
2). Porous ceramics .
- Made of alumina or silicon carbide, with a compressive strength of >10MPa, a ɛfata ma soro-ɔhyew afiri a wɔde yi mframa a ɛwɔ mu no yiyi (te sɛ afifide a wɔde hyew nneɛma a wɔde hyew nneɛma).
4. Nneɛma titiriw a wɔde yɛ adwuma .
1). Carbon a wɔde ayɛ adwuma .
- asase ani fã pɔtee 500-1500m2/g (hwɛ "coal granular activated carbon standard" GB/T 7701.1-2008), betumi adsorb organic matter ne residual chlorine.
2). Magnetic filter media .
- 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%.
