Ngwa nke Reverse Osmosis Membrane na Teknụzụ metụtara na ọgwụgwọ mmiri
- Ọgwụgwọ mmiri mkpofu
Ngwọta mmiri mkpofu bụ isi ngwa nke mebere osmosis membranes. Site na teknụzụ reverse osmosis, ígwè dị arọ ma ọ bụ mmanụ nwere mmiri mkpofu nke ụlọ ọrụ ọkụ na-emepụta na ụlọ obibi akwụkwọ na-esiji nwere ike ịgwọta nke ọma. Enwere ike iji ya na-agwọ nsị n'obodo ukwu, ihe mkpofu ahịhịa, wdg, na-enweta mgbake mmiri.
N'ime usoro nke ike ọkụ ọkụ, a na-eji nnukwu mmiri dị jụụ na-ekesa, nke na-enwekarị adịghị ọcha dị iche iche na nnukwu turbidity. Ọ bụrụ na ewepụrụ ya ozugbo, ọ ga-ebute mmetọ na gburugburu ebe obibi. Nchikota nke oghere eriri ultrafiltration akpụkpọ anụ na polyamide composite reverse osmosis membrane nwere ike na-agwọ ikesa mmiri jụrụ oyi n'ime mmiri reusable na mmiri turbidity n'okpuru 0.02 NTU na mmetọ index n'okpuru 0.7.
Mmiri mkpofu nke ụlọ ọrụ ibipụta na agba agba na-emepụta nwere nnukwu ion nnu, ion agba, na ihe ndị ọzọ. Ojiji nke ultrafiltration na reverse osmosis dual membrane technology nwere ike nyochaa ihe organic, ion nnu, wdg n'ime mmiri mkpofu, na ikuku oxygen oriri nke mmiri emepụtara adịghị elu karịa 10 mg / L, na-egosi mmetụta ọgwụgwọ mmiri dị ịrịba ama.
N'ime usoro ọgwụgwọ mmiri mkpofu ọdịnala nwere ọla dị arọ, ọ dị mkpa ka etinye ihe ndị na-emepụta kemịkalụ, yana ọrụ ọgwụgwọ chọrọ dị elu. Ojiji nke reverse osmosis membranes na multi-stage reverse osmosis technology iji na-agwọ mmiri mkpofu ndị a nwere ike wepu ihe ọla dị arọ dị na mmiri mkpofu nke ọma.
Ihe ndị dị n'ime mkpofu ahịhịa obodo dị ọtụtụ ma dị mgbagwoju anya. Ojiji nke polyamide reverse osmosis membrane maka ọgwụgwọ ya nwere ike ime ka mkpofu ahịhịa dị ọcha na ọkwa mkpofu, na-enweta ọgwụgwọ nke mkpofu ahịhịa.
- Mmepụta mmiri dị ọcha
Mmiri dị ọcha nwere ọtụtụ ngwa na mmiri ọṅụṅụ ụlọ, mmepụta mmepụta ihe, na ọgwụ. Ngwa ndị a nwere ihe dị elu chọrọ maka mmiri, na iji reverse osmosis membranes maka ọgwụgwọ mmiri chọrọ nnabata na ụkpụrụ mmepụta dị mkpa.
N'ihi usoro mmepụta nke mmiri ultrapure dịtụ tozuru oke, a pụrụ iji ihe ndị na-eme ka akpụkpọ ahụ na-emepụta ihe na-emepụta ihe na-emepụta mmiri ultrapure. The reverse osmosis sistem nwere ike ijikwa mmiri na-erugharị 650 m ³/ h ma mepụta mmiri ultrapure na conductivity nke 0.3 m S/cm. Enwere ike idozi nsogbu nke mmebi akpụkpọ ahụ n'oge ọgwụgwọ mmiri site na ụzọ nhicha kemịkal. Usoro ọgwụgwọ mmiri dị ọcha a na-ejikarị eme ihe ugbu a bụ sistemu osmosis electrodeionization system.
N'ihe banyere mmepụta mmiri nke ụlọ ọrụ mmepụta ihe, iji gboo mkpa a na-achọ iji, ndị na-eme nchọpụta ụlọ atụpụtawo ihe ngwọta iji wuo sistemu osmosis na-eji ultra-low pressure roll type composite membrane components. Igwe mmiri na-emepụta otu akpụkpọ ahụ nke akpụkpọ ahụ na-eme ka ọ dị na atụmatụ a nwere ike iru 41.4 cubic mita kwa ụbọchị, na-ejigide ọnụ ọgụgụ na-erughị 99.7%, nke nwere ike zuru ezu izute mmiri chọrọ nke caustic soda mmepụta ụlọ ọrụ.
Na mgbakwunye, na mmepụta nke ụlọ ọrụ chlor alkali, ọ dị mkpa iji nyochaa Ca ² ⁺ na mg ² ⁺ ions na mmiri n'oge usoro mmepụta. Ya mere, PVD reverse osmosis akpụkpọ ahụ nwere ike iji wepụ ha, mgbe n'ịhụ a ala njide ọnụego maka sodium chloride, iji nweta mmiri ọgwụgwọ na ọcha na chlor alkali ụlọ ọrụ mmepụta.
Na mmepụta ọgwụ, iji ultra-low pressure polyamide composite permeable membrane modul ion separation system na itinye usoro ntụgharị osmosis nke okpukpu abụọ iji mepụta mmiri dị ọcha achọrọ na usoro mmepụta ọgwụ nwere ike nweta nsonaazụ dị mma. Atụmatụ ọgwụgwọ mmiri a nwere ọnụego mgbake na-erughị 80% mgbe osmosis nke abụọ gasịrị, nke na-eweta uru akụ na ụba dị ukwuu na ụlọ ọrụ ọgwụ.
