Isebenza njani iFlocculant kunyango lwamanzi?

Iiflocculantsidlala indima ebalulekileyo ekulungisweni kwamanzi ngokuncedisa ekususeni amasuntswana amisiweyo kunye neecolloids emanzini.Inkqubo ibandakanya ukubunjwa kweeflocs ezinkulu ezinokuthi zihlale okanye zisuswe ngokulula ngokucoca.Nantsi indlela iiflocculants ezisebenza ngayo kunyango lwamanzi: 

Ii-Flocculants ziikhemikhali ezongeziweyo emanzini ukuququzelela ukudityaniswa kwamasuntswana amancinci, angazinzisiyo abe ngamasuntswana amakhulu, anokususwa ngokulula abizwa ngokuba ziiflocs.

Iintlobo eziqhelekileyo zeeflocculants ziquka i-inorganic coagulants efanaI-Polymeric Aluminiyam kloride(PAC)kunye neferric chloride, kunye neorganic polymeric flocculants ezinokuba zipolima zokwenziwa ezifana ne polyacrylamide okanye izinto zendalo ezifana ne chitosan.

Ukuqina:

Ngaphambi kwe-flocculation, i-coagulant inokongezwa ukuze idibanise i-colloidal particles.Iicoagulants zinciphisa iintlawulo zombane kumasuntswana, zivumela ukuba zihlangane.

Iicoagulants eziqhelekileyo ziquka i-polymeric aluminium chloride, i-aluminium sulfate (i-alum) kunye ne-ferric chloride.

Ukuqukuqela:

Iiflocculants zongezwa emva kokudibanisa ukukhuthaza ukubunjwa kweeflocs ezinkulu.

Ezi khemikhali zisebenzisana kunye neengqungquthela ezizinzile, ezibangela ukuba zihlangane kwaye zikhawuleze zenze ii-aggregates ezinkulu, ezibonakalayo.

Ulwakhiwo lweFloc:

Inkqubo ye-flocculation iphumela ekudaleni iiflocs ezinkulu kunye ezinzima ezihlala ngokukhawuleza ngenxa yokwanda kobunzima.

Ukubunjwa kwe-Floc kukwanceda ukubanjiswa kokungcola, kubandakanya izinto eziqinileyo, iibhaktheriya, kunye nezinye izinto ezingcolisayo.

Ukuzinzisa kunye nokucaciswa:

Emva kokuba iiflocs zenziwe, amanzi avunyelwe ukuba ahlale kwisitya se-sedimentation.

Ngexesha lokumisa, iiflocs zihlala phantsi, zishiya amanzi acacileyo ngaphezulu.

Uhluzo:

Ukuhlanjululwa okungaphezulu, amanzi acacisiweyo anokuthi afakwe kwi-filtration ukususa nayiphi na i-particle eseleyo engazange ihlale.

Ukubulala iintsholongwane:

Emva kwe-flocculation, ukulungiswa, kunye nokuhluzwa, amanzi ahlala ephathwa nge-disinfectants njenge-chlorine ukuphelisa ii-microorganisms eziseleyo kunye nokuqinisekisa ukhuseleko lwamanzi.

Isishwankathelo, ii-flocculants zisebenza ngokungathathi hlangothi kwentlawulo yeengqungquthela ezimisiweyo, ukukhuthaza ukuhlanganiswa kwamancinci amancinci, ukudala iiflethi ezinkulu ezihlala okanye ezinokuthi zisuswe ngokulula, ezikhokelela kumanzi acacileyo nacocekileyo.
