1. Indima yesihlungi semidiya
Imidiya yesihlungi ibhekisela ezintweni ezisetshenziselwa ukuhlunga, ukuhlukanisa nokuhlanza izinto, futhi zisetshenziswa kakhulu ekuhlanzeni amanzi, ekuhlanzeni umoya, embonini yamakhemikhali neminye imikhakha. Imidiya yokuhlunga ingadlala indima yokuhlunga, ukuhlukanisa, i-adsorption, njll., futhi ingasusa ngempumelelo indaba emisiwe, i-chromaticity, ukungcola, iphunga, i-bacterial flora nezinye izinto eziyingozi emanzini ukuze kuqinisekiswe ukuphepha kwekhwalithi yamanzi; ngesikhathi esifanayo, ingaphinde isuse ukungcola emoyeni futhi ithuthukise izinga lomoya.
Ekwelashweni kwamanzi, imidiya yokuhlunga isetshenziselwa ikakhulukazi ukuhlunga okujulile, ukuhlanzwa kwamanzi nokuhlanza indle. Ekwelashweni komoya, imidiya yokuhlunga ingasetshenziselwa ukuhlunga komoya, ukususwa kothuli nezinye izici. Ngaphezu kwalokho, imidiya yokuhlunga ibuye isetshenziswe kabanzi ezimbonini zamakhemikhali, ezemithi, zokudla nezinye, futhi imisebenzi yazo ihlanganisa ukuhlukanisa, ukuhlanzwa, ukukhangisa, ukugaywa kabusha, njll.
2. Izinhlobo nezimo zohlelo lokuhlunga imidiya
A. Imidiya yesihlungi sesihlabathi
Imidiya yesihlungi sesanti ifanele ukuhlanzwa kwamanzi kampompi, ukukhucululwa kwendle, ukuhlanzwa kwenhlabathi, ukuhlanza amachibi nezinye izinkambu. Umsebenzi wayo ukusebenzisa amasayizi ahlukene embotshana ezingqimba eziningi zokuhlunga ukuze ahlukanise ukungcola kanye nezinhlayiyana emanzini ukuze amanzi acace.
B. Izinto zokuhlunga ikhabhoni ezicushiwe
I-activated carbon filter material i-organic adsorption material esetshenziswa kakhulu ekuhlanzeni amanzi okuphuza, ekuhlanzeni amanzi angcolile, ekuhlanzeni umoya nezinye izinkambu. Umsebenzi wawo ukususa izinto ezingcolisayo njengephunga, umbala, izinto eziphilayo emanzini, kanye nephunga namagesi ayingozi emoyeni.
C. Izinto zokuhlunga i-Fiber
Okubalulekile kwesihlungi se-fiber kuyinto{0}}esebenza kahle kakhulu yokuhlunga okuncane esetshenziswa kumakhemikhali, ekhemisi, ekudleni nakwezinye izinkambu. Umsebenzi wawo ukuhlunga izinhlayiya ezincane oketshezini futhi kukhishwe ama-microorganisms afana namagciwane nama-virus.
