Fa'ato'a fa'aputuga fa'aleaganu'u ta'iala a le atunu'u e tatau ona fa'ailoga fugala'au fa'afefiloi o lo'o iai le chlorine i mea o lo'o i totonu o le chloride, e pei o le maualalo o le chloride (o lo'o i ai le chloride ion 3-15%), medium chloride (o lo'o i ai le chloride ion 15-30%), maualuga chloride (o lo'o i ai le chloride ion. 30% pe sili atu).
O le faʻaogaina talafeagai o saito, sana, asparagus ma isi faʻatoʻaga fanua e le gata e le afaina, ae aoga foi e faʻaleleia ai fua.
I se tulaga lautele, o le faʻaaogaina o faʻamaʻi faʻapipiʻi faʻavae chlorine, tapaa, pateta, pateta suamalie, meleni, vine, suka beets, kapisi, pepa, eggplant, soya, latisi ma isi mea totō e faʻasaʻo i le chlorine ei ai aʻafiaga leaga i fua ma le lelei, ogaoga. fa'aitiitia le manuia tau tamaoaiga o ia fa'ato'aga tupe.I le taimi lava e tasi, chlorine-faʻavae faʻapipiʻi faʻapipiʻi i totonu o le eleele e fausia ai se numera tele o toega chlorine ion, faigofie ona mafua ai le faʻamalosia o le eleele, salinization, alkalinization ma isi mea e le manaʻomia, ma faʻaleagaina ai le siosiomaga o le eleele, ina ia mafai ai ona faʻaogaina le malosi o meaʻai. ua faaitiitia.
