1. Dwuma a filter media di .
Filter media kyerɛ nneɛma a wɔde yiyi nneɛma mu, yiyi mu na wɔtew ho, na wɔde di dwuma kɛse wɔ nsu a wɔde yɛ adwuma, mframa a wɔde yɛ adwuma, nnuru a wɔde yɛ adwuma ne mfuw afoforo mu. Filter media betumi adi dwuma a ɛne sɛ filtering, mpaapaemu, adsorption, ne nea ɛkeka ho, na ebetumi ayi nneɛma a ɛsensɛn hɔ, chromaticity, efĩ, hua, mmoawa afifide ne nneɛma afoforo a epira wɔ nsu mu no afi hɔ yiye de ahwɛ ahu sɛ nsu no yɛ papa; Bere koro no ara mu no, ebetumi ayi efĩ a ɛwɔ mframa mu nso afi hɔ na ama mframa no ayɛ papa.
Wɔ nsuo a wɔde yɛ adwuma mu no, wɔde filter media di dwuma titiriw ma deep filtration, nsuo a ɛho tew ne nsuo fĩ a wɔde yɛ adwuma. Wɔ mframa ayaresa mu no, wobetumi de filter media adi dwuma ama mframa a wɔde yiyi mu, mfutuma a woyi ne afã afoforo. Bio nso, wɔde filter media nso di dwuma kɛse wɔ nnuru, nnuruyɛ, aduan ne nnwuma afoforo mu, na wɔn dwumadi ahorow no bi ne mpaapaemu, ahotew, adsorption, nneɛma a wɔsan de di dwuma, ne nea ɛkeka ho.
2. ahorow ne dwumadie tebea a ɛwɔ filter media mu .
A. Anhwea a wɔde yiyi nneɛma mu .
Sand filter media fata ma tap nsuo a wɔde yɛ adwuma, nsuo fĩ a wɔde yɛ adwuma, nsuo a ɛtɔ gu fam, ɔtareɛ ho a wɔsiesie ne mfuo foforɔ. Ne dwumadie ne sɛ wɔde filter media a ɛwɔ ntoatoasoɔ ahodoɔ a ɛwɔ nsuo mu no mu nsuo a ɛwɔ nsuo no mu no bɛtetew mu ama nsuo no mu ada hɔ.
B. Carbon filter a wɔayɛ no adwuma .
Activated carbon filter material yɛ organic adsorption ade a wɔde di dwuma kɛse wɔ nsu a wɔnom ho ahotew, nsu fĩ a wɔde yɛ adwuma, mframa a wɔtew ho ne mfuw afoforo mu. Ne dwumadi ne sɛ ebeyi efĩ te sɛ hua, kɔla, nneɛma a nkwa wom a ɛwɔ nsu mu, ne mframa a ɛyɛ huam ne nea epira wɔ mframa mu no afi hɔ.
C. Fiber filter a wɔde yɛ nneɛma .
Fibre filter material yɛ ade a ɛkorɔn-efficiency microfiltration ade a wɔde di dwuma wɔ nnuru, nnuruyɛ, aduan ne mfuw afoforo mu. Ne dwumadie ne sɛ ɛbɛyi nneɛma nketenkete a ɛwɔ nsuo mu no afiri mu na ayi mmoawa nketenkete te sɛ mmoawa ne mmoawa afiri mu.
