1. Granular filter media: manu jahpu a madung n-gun-} hpe n-gun jaw ai.
Granular filter media gaw grau nna jai lang ai filter media amyu rai nna, dai gaw hkum hkrang hpe hkap la ai hte pat shingdang ai hku nna hka ni hpe madung hku nna jasan jaseng ya ai. Common amyu ni gaw:
1). Quartz sand: 0.5-1.2mm, n-gun ja ai acid hte alkali ni hpe ninghkap lu ai, manu n law ai, lu sha hka hpe shawng nnan tsi lajang ai hte hka shin ai lam hpe tsi lajang na matu law law lang lang ai ("Industrial Hka hpe jasan jaseng ai ladat" hpe yu u).
2). Activated carbon: 500-1500m du hkra n-gun rawng ai nhprang wan hte hkaulan mam n-gu ni hpe garan nna (data source: US grup yin makawp maga dap EPA), hka hpe jasan jaseng na matu hte nbung hpe jasan jaseng na matu htuk manu ai, organic matter hte heavy metal ni hpe hkap la lu ai.
. Anthracite: n-gun n law ai (1.4{3}1.6g/cm3), quartz hka hte hpaw nna, hka ja ai lam hpe grau kaja hkra galaw ai, law malawng gaw double-layer filter tank ni hta lang ai.
Granular filter media a n kaja ai lam gaw, 3-5 ning daram na sai, n-gun n rawng ai hte aten tup backwashing galaw ra ai.
2. Fiber filter arung arai: kaja ai hte hkrak hkrak gram lajang ai lam hpe lata ai lam
Fiber filter material hpe gaw, n-gun rawng ai arung arai ni hte galaw da ai. Representative amyu ni gaw:
1). Polypropylene fiber: n-gun n rawng ai- hpe n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun hpe jasan jaseng ai jak ni hpe shawng nnan bang na matu jai lang ai PP cotton filter element, pore kaba 1{4}}10μm hku nna galaw mai ai.
2). Glass fiber: nbung katsi ai hpe ninghkap lu ai (280℃hta n-gun n law ai (sh) dai hte maren), n-gun n-gun n-gun shayawm ai ladat zawn re ai bungli galaw ai shara hta n-gun n-gun n-gun n-gun n-gun n-nga ai.
. Ceramic fiber: particle hte fiber a arawn alai ni hpe hpaw nna, n-gun ja ai hkra machyi ai lam hpe ninghkap lu ai atsam, n-gun ja ai n-gun rawng ai ntsin hpe chemical hpaga lam hta hka ja na matu htuk manu ai.
Fiber filter material a n kaja ai lam gaw n-gun n law ai, galu kaba ai- aten ngut ai hpang daw kau na matu loi ai, aten tup galai ra ai.
3. Membrane filter arung arai ni hte rawt jat wa nga ai arung arai ni: hpaji hparat hpe rawt jat galu kaba wa hkra jai lang ai
1). Membrane filter arung arai:
- Microfiltration membrane (0.1-10μm): bacteria hte n-gun n rawng ai arai ni hpe yeng seng kau na, ga shadawn, nta kata na hka hpe jasan jaseng ai ni a jahtum hka htung ni hpe hka ja na.
- Ultrafiltration membrane (0.01-0.1μm): virus ni hpe pat shingdang lu nna, tsi hpaji hta grai lang ai (Membrane Separation Separation Technology Application Guide" hpe yu u).
2). Porous ceramic filter media: High temperature resistant (>.
. Composite filter media nnan: graphene galai shai ai filter media zawn re ai ni, hkap la lu ai atsam hpe 3 lang jan jat wa ai ("Nuture Materials" 2022 sawk sagawn ai lam), raitim, dai hpe n-gun kaba ai hku n galaw shi ai.
4. Kaja ai filter media hpe gara hku lata na?
Filtration yaw shada lam ni hpe madung tawn nna, hkum tsup ai hku jep joi ai lam (n hkru n kaja ai lam hpe yeng seng kau ai, n-gun n rawng ai, garan ginhka ai lam, hka n-gun (pH manu, nbung katsi ai lam) hte manu jahpu budget ni hpe madung tawn nna, hkum tsup ai hku jep joi ai lam. Ga shadawn:
{0}} "quartz sand + shamu shamawt ai carbon" hpe kayau kaya lang ai hpe hka htung ni hta lang ai;
{0}} Electronic hpaga lam hta nga ai hka hpe membrane filter media hte shingdaw ra ai;
{0}} Ceramic filter media hpe nbung katsi ai nbung hpe tsi lajang na matu grau ra sharawng ai.
Htawm hpang de, grup yin hpe makawp maga ai madang ni hpe gram lajang wa ai hte maren, tsaw ai-efficiency hte galu kaba ai- hkye la ai lam ni gaw sawk sagawn ai lam hte rawt jat galu kaba lam a madung lam tai wa na re.
