Dear Ashish,   As I ...

Dear Ashish,

As I suppose, in both cases you will have the same suspended solids, and maybe you could continue with the same cogging period in both media if both media have the same particle size.

Other gestion could be that you use a multimedia filtration system in which you could use a larger size antracite layer over the sand filter to retain the higher particles over, and the smaller particles down in the sand layer.

Whatever case, it will be good that you do a pilot test with all this technologies before exchance the media.

We can help with an innovative containerized technolgy that can be used to filtrate drinking water repleacing clarifiers and sand filtratio in one equimpent, and in just one container you can filtrate from 20 to 100 l/s, depending the inlet parameters savign area and chemicals.
