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 obuhlukene, 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. Njengabaphathi abancane bezinto eziphilayo zasemanzini, badlala indima ebalulekile ngaphansi kwezimo ezifanele zemvelo. Kodwa-ke, lapho ulwelwe lukhula ngokungalawuleki, lungaba nomthelela omubi kakhulu kukhwalithi yamanzi, impilo ye-ecosystem, kanye nemisebenzi yabantu. Kunezinhlobo eziningi zolwelwe, ngalunye lunezici zalo ezihlukile zokukhula nezici zokuzala. I-Cyanobacteria kanye ne-green algae yi-algae evame ukutholakala emanzini ahlanzekile, kuyilapho ama-algae ansundu kanye nama-diatom athambekele kakhulu emachibini kasawoti.
Izingozi ezibangelwa ukuqhakaza kwe-algal
Ukukhiqizwa kolwelwe kuzoholela ekwehleni kokungafihli kwamanzi futhi kuthinte izinga lamanzi. 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 algae, kuhlanganise ngokomzimba, izindlela zamakhemikhali. Izindlela ezingokwenyama ikakhulukazi zihlanganisa ukuhlunga kanye nokukhangisa, kuyilapho izindlela zamakhemikhali ikakhulukazi zisebenzisa ama-agent amakhemikhali ukulawula ukukhula kolwelwe.Ama-algaecides amakhemikhali asetshenziswa kakhulu 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. Izindlela ezingokomzimba ziyisengezo sezindlela zamakhemikhali. Izindlela ezingokomzimba zizodwa azikwazi ukuyiqeda ngokuphelele le nkinga. Uma kune-algae eningi, idinga ukususwa. Lezo ezixhunywe odongeni zidinga ukukhujwa. I-algae efile ngemva kokubulawa kwe-algae yamakhemikhali idinga ukususwa ngokomzimba. Ulwelwe olufile ethangini lesihlabathi ludinga ukususwa ngokugeza ngemuva.
Ukusetshenziswa okuhlongozwayo kwama-chemical agents 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 kuthandwa kakhulu ngoba kuyashesha, kulula futhi kuyayonga. Yiqiniso, indlela ngayinye inobubanzi nemingcele yayo, ngakho ukukhetha kufanele kwenziwe ngokusekelwe ezimweni ezithile ezisetshenziswayo. Ngokuphatha ulwelwe ngokwesayensi, singagcina impilo nobuhle bemithombo yamanzi futhi sivikele inhlalakahle yabantu kanye nemvelo.
