Ukadaulo wochotsa madzi m'nyanja
Chifukwa cha mchere wambiri, madzi a m'nyanja sangagwiritsidwe ntchito mwachindunji. Pali njira ziwiri zomwe zimagwiritsidwa ntchito pochotsa mchere m'madzi am'nyanja ---distillation ndi reverse osmosis.
Njira ya distillation imagwiritsidwa ntchito kwambiri pochotsa mchere m'madzi am'nyanja komanso m'malo omwe ali ndi mphamvu zambiri zotentha. Njira ya reverse osmosis membrane imagwiritsidwa ntchito kwambiri chifukwa chakugwiritsa ntchito kwake komanso kuchuluka kwa madzi amchere.
Njira ya reverse osmosis membrane imachotsa madzi a m'nyanja kuti athandizidwe koyambirira kuti achepetse chipwirikiti chamadzi am'nyanja ndikuletsa kukula kwa mabakiteriya, algae, ndi tizilombo tina. Kenako, pampu yapadera yothamanga kwambiri imagwiritsidwa ntchito kukakamiza madzi a m'nyanja kuti alowe mu nembanemba ya reverse osmosis.
Chifukwa cha kuchuluka kwa mchere m'madzi a m'nyanja, madzi a m'nyanja a reverse osmosis amayenera kukhala ndi chiwopsezo chachikulu cha kutulutsa mchere, kukana dzimbiri, kukana kuthamanga kwambiri, komanso kukana kuipitsidwa. Pambuyo pothandizidwa ndi nembanemba ya reverse osmosis, mchere wa m'madzi a m'nyanja umachepa kwambiri, ndipo TDS imakwera kuchoka pa 36000 mg/L kufika pa 200 mg/L. Ubwino wa madzi pambuyo pochotsa mchere ndi wabwino kwambiri kuposa madzi apampopi, kotero amatha kugwiritsidwa ntchito ndi mafakitale, malonda, okhalamo, ndi zombo.
HID mtundu wamadzi am'nyanja RO mtundu wa SW-8040-HR ndiwoyenera kuyeretsa madzi am'nyanja ovuta. Kutsitsa kwake kokhazikika kumatha kukhala mpaka 99.8% ndi kukakamiza kwa 800psi. Takulandilani kufunsa!

1. Kuthamanga kwapakati ndi kukanidwa kwa mchere kumatengera mikhalidwe yoyesera: 25⁰C, pH 7.5, 8% kuchira.
2. Kukana mchere wokhazikika nthawi zambiri kumatheka mkati mwa maola 24-48 akugwiritsa ntchito mosalekeza, kutengera mawonekedwe a madzi a chakudya ndi momwe amagwirira ntchito.
3. Malo ogwira ntchito otsimikizika +/- 3%.
4. Kuthamanga kwapakati pa chinthu chimodzi kumasiyana ndi +/-15%.
5. Kutsika kwapakati kwa chinthu chimodzi (max.): 15psi.
