Ua rau fouling hauvUltrafiltration system:
(1) Cov dej kub ntawm qhov dej ntawm ultrafiltration tsawg dhau, uas ua rau muaj kev ua haujlwm nce ntxiv;
(2) Ultrafiltration membranefouling yog tshwm sim los ntawm cov dej tsis huv, ntau cov kab mob thiab cov algae, uas yog, SDI ntawm lub zog muaj zog heev, ua rau ultrafiltration fouling;
(3) Lub zog ntws ntawm ultrafiltration nce, uas tshaj cov dej tsim muaj peev xwm ntawm lub lim membrane;
(4) Lub inlet siab siab dhau lawm. Txhawm rau txhawm rau ua kom cov dej ntau lawm, ua kom lub zog nkag siab ntawm ultrafiltration.
Thaum ultrafiltration muaj kuab paug, nws yuav muaj kev cuam tshuam zoo rauRO systemthiab ua kom muaj kuab paug thaiv, feem ntau ntawm cov hauv qab no:
(1) Cov dej tsis zoo deteriorates, tus nqi SDI yuav siab dua los yog tshaj tus qauv, thiab cov xim ntawm SDI tus nqi kuaj diaphragm yuav tsaus dua;
(2) Covrov qab osmosis membraneyog qias neeg thiab thaiv, uas ua rau poob sai ntawm cov dej ntau lawm ntawm qhov rov qab osmosis system;
(3) Thaum UF muaj kuab paug hnyav, ib txheej ntawm "sponge" yuav raug tsim tawm hauv UF. Thaum lub sij hawm ntxuav cov tshuaj, cov seem ntawm NaOH los yog sodium hypochlorite tsis tuaj yeem ntxuav hauv lub sijhawm, uas yuav raug tso tawm maj mam, uas yuav ua rau muaj kev puas tsuaj loj rau cov kab mob RO tom ntej.
