Milozera itatu yayikulu yoyezera magwiridwe antchito a reverse osmosis nembanemba ndi kutulutsa kwamadzi, kuchuluka kwa madzi amchere komanso kutsika kwa membrane, komwe kumadziwika kwambiri ndi kuthamanga kwamadzi.
Pakadali pano, pali ma membranes ambiri osinthika a osmosis omwe amagulitsidwa pamsika, ndipo malinga ndi malingaliro osiyanasiyana, gululi silifanana. Mitundu yosiyanasiyana imayikidwa mosiyana, ndipo mitundu ndi zitsanzo ndizosiyana. Lero, tiyeni tikambirane za gulu la reverse osmosis nembanemba malinga ndi zinthu ndi mitundu ya nembanemba chinthu cha mtundu waukulu.
Mitundu ya reverse osmosis nembanemba:
1.Kutengera mtundu wa membrane element, imatha kugawidwa kukhala nembanemba yofanana, nembanemba ya asymmetric ndi nembanemba yophatikiza.
2. Malinga ndi maonekedwe a zinthu za nembanemba, zikhoza kugawidwa mu nembanemba otsika kuthamanga, kopitilira muyeso-otsika kuthamanga nembanemba, kwambiri kopitilira muyeso-otsika kuthamanga nembanemba, otsika mphamvu nembanemba, kopitilira muyeso-otsika mphamvu nembanemba, mkulu desalination mlingo nembanemba, ultra-mkulu desalination nembanemba, mkulu boron kuchotsa nembanemba, lalikulu flux nembanemba, anti-kuipitsa nembanemba ndi zina zotero.
3. Malinga ndi kugwiritsa ntchito nembanemba ya reverse osmosis, imathanso kugawidwa kukhala nembanemba yamadzi apampopi, nembanemba yamadzi a brackish, nembanemba yamadzi a m'nyanja yamadzi a m'nyanja, nembanemba ya kalasi ya semiconductor, nembanemba yolekanitsa yokhazikika, nembanemba yochotsa tizilombo toyambitsa matenda ndi zina zotero.
4.Malinga ndi zipangizo zake zopangira, zimathanso kugawidwa mu cellulose acetate membrane, polyamide membrane, composite membrane.
5.Kutengera kukula kwa membrane element, imatha kugawidwa kukhala nembanemba yaying'ono yosinthira osmosis, nembanemba ya 4040 ndi nembanemba ya 8040.
6.Malinga ndi kamangidwe kameneka, kakhoza kugawidwa mu membrane inorganic, organic membrane, disc chubu reverse osmosis membrane mtundu / DTRO.
Magulu a reverse osmosis membranes:
1. Cellulose acetate:
Ma cellulose acetate, omwe amadziwikanso kuti acetyl cellulose kapena cellulose acetate, nthawi zambiri amagwiritsa ntchito thonje ndi nkhuni ngati zida zopangira mapadi acetate kudzera mu esterification ndi hydrolysis. M'kupita kwa nthawi, kuchuluka kwa mchere wamtundu woterewu kumachepa pang'onopang'ono, ndipo kuthekera kwa kuipitsidwa kumakulirakulira.
2.Polyamide:
Ma polyamides amatha kugawidwa kukhala aliphatic polyamides ndi polyamides onunkhira. Pakadali pano, ma polyamide onunkhira amagwiritsidwa ntchito kwambiri pamsika, omwe ali ndi zofunikira zochepa pamtengo wa PH, koma klorini yaulere imatha kuyipitsa kwambiri.
3. Kuphatikizika kwa membrane:
Nembanemba yophatikizika ndiyomwe imadziwika kwambiri reverse osmosis nembanemba pamsika pano, makamaka yopangidwa ndi zida ziwiri zomwe zili pamwambazi, kusanjikiza kwapambuyo kwa osmosis ndi khungu lolimba lotchinga, lomwe lingalepheretse ndikulekanitsa mchere, womwe umadziwika kuti desalting wosanjikiza, makulidwe ake amakhala 50nm. Pansipa pali porous layer yolimba, yomwe imadziwikanso kuti nembanemba yoyambira, ndipo pansi imagwiritsa ntchito zinthu zopanda nsalu ngati chothandizira. Nembanemba yophatikizika imathetsa bwino zofooka za zida ziwiri zomwe zili pamwambazi, ndipo imakhala ndi zabwino zomwe zimalowera kwambiri, kuthamanga kwamadzi kwakukulu komanso kugwiritsa ntchito mwamphamvu kwambiri.
Weifang Toption Machinery Co., Ltd amapereka mitundu yonse ya zida zochizira madzi ndi zowonjezera kuphatikiza nembanemba za RO. Ngati mungafune zambiri, chonde pitani patsamba lathu www.toptionwater.com. Kapena ngati muli ndi chosowa, chonde musazengereze kulankhula nafe.
