Dose SMBS before feeding to RO. It will remove chlorine and will bring ORP in desired range.

For high pressure difference in pre treatment (I hope it’s MGF) backwash and rinse it regularly for at least 15 minutes each, if problem sustains, change the media.

if chlorination and de chlorination assemblies are not installed in water system than what shall be happened in PW and WFI ? We are manufacturer of Ophthalmic production.

Dear Mr. Nimesh,

The installation of chlorine and dechlorination units depends upon your infeed water profile, if the conentration is with the acceptable range and doesnot have impact in your current setup. then no need.

Thanks
