As per link given, Chlorine is able to inactivate most bacteria, viruses, and protozoa. However, some has higher tolerance against chlorine, just need more chlorine and more time to disinfect except for
"Toxoplasma and Cryptosporidium oocysts are highly resistant to chlorine disinfection. Chlorine alone should not be expected to inactivate these pathogens in drinking water. Filtering water supplies with a 1 micron absolute filter is recommended to physically remove the oocysts before chlorination if these pathogens are of concern"Most of the (Inactivation %) shown in the table even for those high tolerance against chlorine are 99%, meaning chlorine is able to kill most of the bacteria, viruses and protozoa. Btw, Syabas didnt just add chlorine alone to disinfect the water, there are many other chemicals added, hence the main concern in water filtration is the chemicals and not the bacteria

Yep. Also, if you guys overlooked, the concentration of chlorine (mg/L) used in the test for Toxoplasma and Cryptosporidium which are common cause of diaerra is respectively 100 and 80. Even with such highly toxic concentration it takes pretty long to deactivate them due to them being highly resistant to chlorine. For the record, the concentration of chlorination used by Syabas is in the range of 0.2 to 5.0 mg/L, in line with the standard set by Ministry of Health.

You are still trying to incite fear that a filtered JBA water is not safe to drink without UV ?
Do you have any reliable reports to prove that that those who drink filtered water without UV will get sick by the so called cysts/Cynobacteria ?
Do you have any official Malaysian report to prove that after Chlorine disinfection, cysts/cynobacteria still present in our JBA water ? If you don't have facts to back you up, please don't spread lies in the forum.
UV disinfection is one the (quick) ways to kill off bacteria's in drinking water. Other way is submicron filtration with absolute-sized pore filter media (as oppose to nominal). Or boiling, if you fancy slow way.
