Ama-algae azala ngokushesha futhi ngokuvamile kunzima ukuwaqeda, okuye kwaba ngenye yezinkinga ekugcineni indawo enempilo yamanzi. Abantu bahlala befuna izindlela ezinhle zokubasiza babhekane nolwelwe ngempumelelo. Ezindaweni ezahlukene zekhwalithi yamanzi kanye nezindawo zamanzi ezinobukhulu obuhlukene, kufanele kukhethwe izindlela ezifanele zokususa ulwelwe ukuze kufezwe ukusebenza kahle okuphezulu ngenkathi kuvikelwa imvelo. Uma ufuna ukwelapha izindawo zamanzi ezinkulu, njengamachibi okubhukuda, ukususa ulwelwe ngamakhemikhali kuyindlela efanele kakhulu kuwe.
Ukuqonda ulwelwe
Ama-algae ayizinto eziphilayo zasemanzini. Iningi lama-algae liyi-autotrophs (lenza i-photosynthesis) kanti amanye ama-algae angama-heterotrophs. Njengabaphathi abancane bezindawo zemvelo zasemanzini, adlala indima ebalulekile ngaphansi kwezimo ezifanele zemvelo. Kodwa-ke, lapho ama-algae ekhula engalawuleki, angaba nomthelela omkhulu ekhwalithini yamanzi, empilweni yezindawo zemvelo, kanye nemisebenzi yabantu. Kunezinhlobo eziningi zama-algae, ngalinye linezici zalo zokukhula nokuzala ezihlukile. Ama-Cyanobacteria kanye nama-algae aluhlaza yi-algae avame ukutholakala emachibini ahlanzekile, kuyilapho ama-algae ansundu kanye nama-diatoms ethambekele kakhulu emachibini anosawoti.
Izingozi ezibangelwa ukuqhakaza kwe-algal
Ukuzalana kwe-algae kuzoholela ekunciphiseni ukubonakala kwamanzi futhi kuthinte ikhwalithi yamanzi. Ngaphezu kwalokho, ukukhula kwe-algae kungathinta ubuhle bamanzi futhi kunciphise inani lawo lokusetshenziswa kwezokuzijabulisa noma kwezentengiselwano.
Ukuze kulondolozwe impilo nokubukeka kwezindawo zamanzi futhi kuvinjelwe imiphumela emibi yokuqhakaza kakhulu kwe-algal, ukususwa kwe-algae sekubaluleke kakhulu. Ukulawulwa kwe-algae kubaluleke kakhulu ezindaweni ezifana namachibi okubhukuda, ukufuywa kwezinhlanzi, kanye nezindawo zamanzi ezihlotshiswe ngotshani zomphakathi nezangasese.
Izindlela zokwelapha ulwelwe
Kunezindlela eziningi zokwelapha ulwelwe, okuhlanganisa nezindlela zomzimba, zamakhemikhali. Izindlela zomzimba zifaka phakathi ukuhlunga kanye nokumuncwa, kuyilapho izindlela zamakhemikhali zisebenzisa kakhulu ama-chemical agents ukulawula ukukhula kolwelwe. Ama-algaecides amakhemikhali asetshenziswa kakhulu ahlukaniswe kakhulu ngama-oxidants kanye nama-non-oxidants.
Kunezici eziningana okufanele uzicabangele lapho ukhetha indlela efanele yokususa ulwelwe. Emadamini amakhulu noma emithonjeni yamanzi okuphuza, ukususa ulwelwe ngamakhemikhali kungaba yindlela esheshayo nephumelelayo kakhulu. Emadamini amancane amanzi, njengamachibi okubhukuda asekhaya noma edamini elincane lamanzi, izindlela ezibonakalayo zingase zifaneleke kakhulu. Izindlela ezibonakalayo ziyisengezo sezindlela zamakhemikhali. Izindlela ezibonakalayo zodwa azikwazi ukuqeda ngokuphelele inkinga. Uma kune-algae eningi, kudingeka zisuswe. Lezo ezinamathele odongeni kudingeka zikhuhlwe. Ulwelwe olufile ngemva kokubulawa kolwelwe ngamakhemikhali kudingeka lususwe ngokomzimba. Ulwelwe olufile ethangini lesihlabathi ludinga ukususwa ngokugeza ngemuva.
Ukusetshenziswa okuhlongozwayo kwamakhemikhali ukususa ulwelwe
Ukususwa kwe-algae ngamakhemikhali kunezinzuzo eziningi. Okokuqala, kusebenza ngokushesha futhi kunganciphisa 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 i-algae ikhange kakhulu ezimweni eziningi.
Sekukonke, Uma ubhekene nenkinga yokuqhakaza kwe-algae ngokweqile, ukukhetha indlela efanele yokususa i-algae kubalulekile. Nakuba kunezindlela eziningi ongakhetha kuzo, ukususa i-algae ngamakhemikhali kuthandwa kakhulu ngoba kuyashesha, kulula futhi kuyonga imali. Yiqiniso, indlela ngayinye inobubanzi kanye nemikhawulo yayo, ngakho-ke ukukhetha kudinga ukwenziwa ngokusekelwe ezimweni ezithile ekusetshenzisweni okungokoqobo. Ngokuphatha i-algae ngokwesayensi, singalondoloza impilo nobuhle bezindawo zamanzi futhi sivikele inhlalakahle yabantu kanye nezindawo zemvelo.
