Nyob rau xyoo 1970 thiab 80s, Choa Chu Kang Water Treatment Plant hauv Singapore tau siv cov txheej txheem ① xuab zeb filtration (362,000 tons / hnub) kom tshem tawm turbidity, kab mob, thiab cov teeb meem loj.

Nrog rau kev nce qib ntawm cov thev naus laus zis thiab kev txo qis hauv cov nqi siv hluav taws xob, xyoo 2008, Choa Chu Kang Water Treatment Plant tau ua tiav thawj zaug, hloov cov xuab zeb lim nrog ② organic membranes (hloov ib nrab ntawm lub peev xwm - thawj Phaj 1 cog ua rau xyoo 1976 nrog 182,000 tons / hnub).
Tom qab ntawd, paub txog qhov zoo ntawm cov khoom siv ceramic, nws tau npaj los siv cov txheej txheem ceramic membrane los txhim kho qhov seem ntawm ib nrab ntawm lub peev xwm. Xyoo 2011, thawj ③ ceramic membrane pilot cog (1200 tons / hnub, saib daim duab hauv qab no) tau tsim los ntawm Choa Chu Kang Water Treatment Plant, nrog kev nqis peev ntawm S$ 5 lab. Tom qab 18 lub hlis ntawm kev sim ua haujlwm nyuaj, kev ua haujlwm siab thiab kev ntseeg siab ntawm cov khoom siv ceramic rau kev kho dej tau raug tshawb xyuas tag nrho. Qhov thib ob upgrade project ntawm Choa Chu Kang Water Treatment Plant pib nyob rau hauv 2016, tag nrho siv cov plaub hom ceramic membrane (lwm ib nrab ntawm lub peev xwm - thawj theem 2 cog tsim nyob rau hauv 1981 nrog ib tug muaj peev xwm ntawm 182,000 tons / hnub). Qhov no suav nrog kev tsim cov nroj tsuag kho tshiab, txhim kho cov txheej txheem ceramic membrane, thiab ntxiv ozone{13}}cov txheej txheem ua kom muaj roj carbon sib sib zog nqus. Qhov project siv kwv yees li peb xyoos ua kom tiav, nrog rau tag nrho cov peev ntawm S$ 162 lab.
Hauv cov ntsiab lus, ib nrab ntawm Choa Chu Kang Water Treatment Plant cov xuab zeb lim tau hloov nrog cov organic ultrafiltration (2008), thiab lwm ib nrab tau hloov nrog ceramic ultrafiltration (2019).
