Lub 210,000 tons / hnub ceramic membrane retrofit project ntawm Hampton Lord Water Treatment Plant nyob rau hauv UK ntxiv ib theem pom rau cov txheej txheem uas twb muaj lawm, txhim kho 20 ceramic membrane filtration units, nrog rau cov khoom pab rau backwashing, tshuaj ntxuav, thiab neutralization ntawm cov tshuaj pov tseg. Ceramic membrane units tau muab tso rau tom qab cov txheej txheem qhia meej uas twb muaj lawm thiab ua ntej granular activated carbon (GAC) pom, tsim kom muaj lub cev muaj zog heev. Tom qab kev ua haujlwm, cov txheej txheem tshuaj tua kab mob ultraviolet (UV) tuaj yeem raug tshem tawm - cov txheej txheem UV thawj tau pom kev ua haujlwm tsis zoo thiab tsis tu ncua nce nqi khiav lag luam, ua rau nws tsis muaj kev lag luam thiab ib puag ncig ua tau.
Cov dej nyoos rau Hampton Lord Water Treatment Plant yog muab los ntawm Chelmarsh Reservoir. Tom qab kev kho nyob rau hauv lub clarifier, sodium hypochlorite yog ntxiv rau nruab nrab ua ntej - tshuaj tua kab mob ua ntej cov dej ntws los ntawm lub ntiajteb txawj nqus mus rau hauv lub filtration theem.] Yav tas los, no filtration seem yog ib tug xuab zeb lim, tom qab ntawd haum nrog activated carbon lim media, combining activated carbon tiv thaiv cov tshuaj tiv thaiv thiab dej filtration functions kom tshem tawm cov volatile raw cov ntaub ntawv xws li cov kuab tshuaj organic thiab tshuaj tua kab mob. Txawm li cas los xij, tom qab cov xuab zeb lim tau hloov mus rau carbon lim, cov cuab yeej pom thiab cov pa roj carbon adsorption efficiency tsis tau mus txog qib siab (li no, ib qho laj thawj rau kev txiav txim siab ceramic membrane kho). Tom qab cov pa roj carbon lim dej, cov dej yog tshuaj tua kab mob los ntawm cov khoom siv ultraviolet, thiab tom qab ntawd chlorinated ua ntej nkag mus rau hauv lub tank tshuaj tua kab mob.
Qhov kev hloov kho yuav tsum ntxiv cov khoom siv lim dej ceramic ntawm lub tank kom meej thiab cov lim roj carbon. Nees nkaum ceramic lim units raug xa mus, muab faib ua ob pawg loj, nrog rau 10 units ua haujlwm ntawm nws tus kheej hauv txhua qhov array. Txhua chav tsev lim dej ceramic muaj 90 lub lim dej ua tau-hauv, rau tag nrho 1800 ceramic lim cartridges thoob plaws hauv qhov project.
