1. Ol samting bilong filta bilong ol samting bilong graun
1). Quartz wesan
- Bikpela hap em silikon daioksait (SiO₂), wantaim bikpela hatnes (Mohs hatnes 7) na strongpela kemikel stebiliti. Ol i save yusim planti long ol ples bilong filta bilong wara tritmen.
- Ol spesifikasen bilong komon: 0.5-1.2mm (koas filtresen), 0.3-0.5mm (gutpela filtresen), lukluk long "Standet bilong Kwats San Piksa Midia bilong Wara Tritmen" (CJ/T 43-2005).
- Ol samting i no gutpela: bikpela densiti (2.65g/cm3), bikpela bekwas eneji konsumsen.
2). Anthracite
- Porositi i antap olsem 50%-60%, wantaim strongpela adsorpsen kapasiti, na planti taim ol i save yusim wantaim kwots wesan long kamapim wanpela dabol-leia filta tenk.
- sais bilong ol hap: 0.8-1.8mm, densiti 1.4-1.6g/cm3 (i lait moa long quartz wesan, we inap daunim presa bilong was bek).
3). Zeolite
- Natural aion eksens samting, wantaim bikpela adsorpsen ifek long amonia naitrojen na ol hevi metal, i gutpela long tritmen bilong ol pipia wara bilong akwakalsa.
2. Sintetik polima samting filta midia.
1). Polipropilen (PP) fiber
- Asid na alkali i no inap kisim sik (pH 1-14), ol i save bagarapim ol samting bilong daunim sik, na ol i mekim i kamap ol filta beg o ol samting bilong filta, ol i yusim long ol kemikel na ol indastri bilong kaikai.
- stretpela bilong Filtresen: 1-100μm (ol i stretim bihainim pasin bilong samapim densiti).
2). Polyesta (PET) i no bilong dispela laplap ol i wokim
- bikpela strong na gutpela win permeabiliti, ol i save yusim planti taim long filtresen bilong win (olsem HEPA filta).
3). Polietilen (PE) sintered filta element
- gutpela straksa i kamap long hai- telimperet sintering, wantaim stretpela mak inap long 0.1μm, ol i yusim long redim wara long rot bilong altrapur.
3. Metal na seramik filta midia
1). Ol steinles stiel waya mes
- Model 304/316L, bikpela mak bilong tempereja i no inap long kisim bikpela tempereja ( I no gat o wankain olsem 800 digri ), pore sais bilong 20-200 mesh, ol i yusim long ol petrolium na ol indastri bilong marasin.
2). Ol porous seramik
- Made of alumina or silicon carbide, with a compressive strength of >10mPa, i stret long hai-} temperature flue ges das bilong rausim das bilong ges (olsem ol ples bilong kukim pipia).
4. Spesel wok samting
1). Kabon i wok
- Spesifik pes eria 500-1500m2/g (luk long "Kal Granular Aktivet Kabon Standet" GB/T 7701.1-2008), i ken kisim ol ogen samting na residuel klorin.
2). Mignetik filta midia
- 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%.
Ol tingting i go bikpela moa:
- Komposit filta midia (olsem "kwatz san + aktivet kabon") i save tingbaot tugeta filtresen blong bodi mo kemikol adsorpsen;
- Ol samting i wok long kamap olsem grafen filta membran (filtresen ekyuresi 0.001μm) i stap yet long laboratori stej na ol i dia tumas.
