precoat leaf filteration
(OP)
I AM USING A PRECOAT FILTER IN MY CAUSTIC SODA PLANT FOR BRINE FILTERATION. THE PRECOAT MEDIA IS CELLULOSE.
THE FILTERS ARE RUNNING AT 40% OF RATED CAPACITY.
I WANT TO KNOW WHETHER
INCRESING FILTER AID WILL REDUCE PRESSURE DROP
FILTR CLOTH IS OF 40 MICRON. SHOULD I INCRESE THE SIZE
WILL IT REDUCE THE QUALITY OF BRINE
PLEASE GIVE YOUR OPINIONS
THANKS

RE: precoat leaf filteration
We had similar problems in filter dP and filtrate pH control, which was crucial for brine chealating. Adding 50% more filter aid and increasing the forward circulation step (during the filter change-over cycle) seemed to help, and we have excellent filter life since. The coating on filter seemed to hold although it was thicker
If the filter is running at 40% it's capacity, it might be due to excessive blinding of the filter cloth. A 4% HCl wash was recommended for cleaning the filter cloth. Contact your filter manufacturer for details.
