I-algae izala ngokushesha futhi ngokuvamile kunzima ukuyiqeda, okuye kwaba enye yezinkinga ekugcineni indawo yamanzi enempilo. Abantu bahlale befuna izindlela ezinhle zokubasiza babhekane nolwelwe ngendlela efanele. Ezindaweni ezihlukene zekhwalithi yamanzi kanye nemizimba yamanzi yobukhulu obuhlukahlukene, izindlela ezifanele kufanele zikhethwe ukuze kukhishwe ulwelwe ukuze kuzuzwe ukusebenza kahle okuphezulu ngenkathi kuvikela imvelo. Uma ufuna ukwelapha imizimba emikhulu yamanzi, njengamachibi okubhukuda, ukususa ulwelwe ngamakhemikhali kuyindlela ekufanele kakhulu.
Ukuqonda i-algae
Ulwelwe yizinto eziphila emanzini. Ulwelwe oluningi luyi-autotrophs (lwenza i-photosynthesis) kanti olunye ulwelwe luyi-heterotroph. Futhi, ezinye "i-algae" ezifana ne-pink algae empeleni ziyisikhunta. Njengabaphathi abancane bezinto eziphilayo zasemanzini, badlala indima ebalulekile ngaphansi kwezimo ezifanele zemvelo. Kodwa-ke, lapho ulwelwe lukhula ngendlela engalawuleki, lungaba nomthelela omkhulu kukhwalithi yamanzi, impilo ye-ecosystem, kanye nemisebenzi yabantu. Kunezinhlobo eziningi zolwelwe, ngalunye lunezici zalo ezihlukile zokukhula nezici zokuzala. I-Cyanobacteria kanye nolwelwe oluluhlaza kuwulwelwe oluvame ukutholakala emachibini anamanzi ahlanzekile, kuyilapho ulwelwe olunsundu kanye nama-diatom kuthambekele kakhulu emachibini anosawoti, njengamachibi abulawe amagciwane ngamajeneretha amanzi anosawoti awuhlobo lwemishini yokubulala amagciwane echibini lokubhukuda.
Izingozi ezibangelwa ukuqhakaza kwe-algal
Ukukhiqizwa kolwelwe kuzoholela ekwehleni kokungafihli kwamanzi, kuthinte izinga lamanzi, futhi kunikeze indawo yokuzalanisa amagciwane. Ukwengeza, ukukhula kwe-algae kungathinta ubuhle bomzimba wamanzi futhi kunciphise inani layo ekusetshenzisweni kokuzijabulisa noma ukuhweba. Ukuze ulondoloze impilo nokubukeka kwemithombo yamanzi futhi uvimbele imiphumela emibi yokuqhakaza kwe-algal ngokweqile, ukususwa kolwelwe sekubalulekile. Ukulawulwa kwe-algae kubaluleke kakhulu ezindaweni ezifana namachibi okubhukuda, i-aquaculture, kanye nezindawo zamanzi zomphakathi nezizimele.
Izindlela zokwelapha ulwelwe
Ziningi izindlela zokwelapha ulwelwe, kuhlanganise ngokomzimba, izindlela zamakhemikhali. Izindlela ezingokwenyama ikakhulukazi zihlanganisa ukuhlunga kanye nokukhangisa, kuyilapho izindlela zamakhemikhali ikakhulukazi zisebenzisa ama-chemical agents ukulawula ukukhula kolwelwe. Ama-algaecides asetshenziswa kakhulu amakhemikhali ahlukaniswa kakhulu abe ama-oxidants kanye nama-non-oxidants.
Kunezici eziningana okufanele uzicabangele lapho ukhetha indlela efanele yokususa ulwelwe. Emizimbeni emikhulu yamanzi noma emithonjeni yamanzi okuphuza, ukususwa kwe-algae ngamakhemikhali kungase kube indlela esheshayo nephumelelayo kakhulu. Emizimbeni emincane yamanzi, njengamachibi okubhukuda asekhaya noma izindawo ezinamanzi amancane, izindlela ezibonakalayo zingase zifaneleke kakhulu.
Ukusetshenziswa okuhlongozwayo kwama-agent amakhemikhali ukususa ulwelwe
Ukususwa kwe-algae kwamakhemikhali kunezinzuzo eziningi. Okokuqala, isebenza ngokushesha futhi inganciphisa kakhulu inani le-algae ngesikhathi esifushane. Okwesibili, kulula ukuyisebenzisa, vele ulandele imiyalelo bese wengeza inani elifanele lamakhemikhali. Okokugcina, izindleko eziphansi kakhulu zenza le ndlela yokususa ulwelwe ikhange kakhulu ezimweni eziningi.
Sekukonke, Lapho ubhekene nenkinga yokuqhakaza kwe-algae ngokweqile, ukukhetha indlela efanele yokususa ulwelwe kuyisihluthulelo. Nakuba ziningi izindlela ongakhetha kuzo, ukususwa kwe-algae ngamakhemikhali kuyathandwa ngenxa yokusebenza kwayo, ukusebenziseka kalula, nomnotho. Yiqiniso, indlela ngayinye inobubanzi nemikhawulo yayo, ngakho ukukhetha kufanele kwenziwe ngokusekelwe ezimweni ezithile ekusebenzeni okungokoqobo. Ngokuphatha ulwelwe ngokwesayensi, singakwazi ukugcina impilo nobuhle bemithombo yamanzi futhi sivikele inhlalakahle yabantu kanye nemvelo.
