Query on backwash UF purifiers

Want to buy a backwash UF Purifer

Hello,

I want to check if there are any "Auto Backwash" UF Water Purifiers available in India? I have seen some RO membranes which can be auto backwashed, but not UF on the net.  

Can anyone help me on this. I am looking for this to use in my house. 

Thank you,

Shri
