Madzi ndi chakudya chofunikira kwambiri kwa anthu, madzi kwenikweni samwedwa chifukwa cha zinthu zosiyanasiyana zakunja.ln kuti akwaniritse miyezo yakumwa yathanzi. Madzi amayenera kusefera kwambiri ndikusunga zinthu zopindulitsa zamchere.Ubwino wa madzi umasiyana kwambiri kudera ndi dera.
Dongguan Kinda imapereka mayankho ogwira mtima komanso azachuma kutengera mtundu wamadzi am'munda kuti akwaniritse zofunikira zamabizinesi ndi chitukuko.
Mu China, waukulu ma CD zinthu zam'madzi pamsika: kumwa madzi oyera, madzi osungunuka,kumwa madzi achilengedwe a masika, kumwa madzi amchere, kumwa madzi achilengedwe.
Njira ya mankhwala aliwonse ndi yosiyana pang'ono.Kapangidwe ka kulongedza madzi akumwa, makamaka kumwa madzi amchere, ndikosavuta.Kuonetsetsa kuti mchere uli ndi zinthu zambiri, ukadaulo wa reverse osmosis sugwiritsidwa ntchito.
GB 19298-2014 ndi GB8537-2018, National Food Safety Standard for Drinking Natural Mineral Water, ndiyo miyeso yayikulu pamsika, yomwe ili ndi zofunikira pazachilengedwe komanso ma index owonjezera a Pseudomonas Aeruginosa.
Pseudomonas aeruginosa imatha kulowa m'madzi omalizidwa kudzera mu fyuluta yolakwika, kotero ndikofunikira kusankha fyuluta yoyezera bwino kwambiri komanso yodalirika kuti mutsimikizire mtundu wamadzi omalizidwa.
Zosefera zazikulu ndi zinthu zosefera zovomerezeka pamachitidwe amadzi am'mabotolo:
1. coarse fyuluta - tinthu kuchotsa fyuluta chinthu: ntchito mfundo: potulukira, adamulowetsa mpweya kunsi kwa mtsinje, ion kuwombola utomoni kunsi kwa mtsinje.Zosefera zomwe mukufuna: PP yosungunuka, 2-3um kulondola mwadzina, pafupifupi 10um kulondola kwathunthu.
2. Zosefera zosefera mwatsatanetsatane: zoyenera madzi amchere / madzi oyeretsedwa, tetezani chinthu chomaliza;Chotsani 0.5-2.0um particles ndi zoipitsa zina;Chepetsani kuchuluka kwa tizilombo tating'onoting'ono, kusefa analimbikitsa: PP kupindana, 0.2um mwadzina kulondola, mtheradi kulondola 1um kapena choncho.
3. Security fyuluta pamaso RO n'zosintha osmosis: PP kusungunula-utsi, kulondola mwadzina 5um, mtheradi mtheradi pafupifupi 20um, chotsani particles, colloid ndi zosafunika zina m'madzi, ndi kukwaniritsa zofunika odana doko permeable nembanemba madzi SDI yaing'ono F5 .
4. chinthu chomaliza cha fyuluta: choyenera madzi amchere, madzi oyeretsedwa ndi madzi ena a m'mabotolo;Kuchotsa tizilombo toyambitsa matenda timene timayambitsa kuwonongeka kwa madzi komanso kuwononga thanzi la munthu;Analimbikitsa mwachangu pachimake :0.22pm/0.45um PES/NG6/PVDF tizilombo ting'onoting'ono kalasi bactericidal pachimake.
5. Fyuluta yopumira ya tanki yosungiramo madzi: chinthu chofananira: chipolopolo chachitsulo chosapanga dzimbiri + PTFE 0.22um fyuluta.
6. CIP fyuluta: akusonyeza fyuluta chinthu: chitsulo chosapanga dzimbiri chipolopolo + PP kusungunula-kuphulika / PP kupukutira / GF lopinda fyuluta chinthu 2-3um kulondola mwadzina, 10um mtheradi kulondola.
