Filter press precoating, it's just one way to help your press run more efficiently and make your filter cloths and filter plates last longer. Read on to learn more about this extremely beneficial process.
What is precoating?
Precoating a filter press entails placing a thin layer of material or filter aid, mixed with water between either:
The filter media and the sludge, helping make press cycles shorter and more efficient.
The filter cake and the filter cloth, which helps cut down on filter cloth washing.
The layer of filter aid helps trap the small particles in the sludge that might otherwise flow right through the filter cloths.
TYPES OF PRECOAT
I mentioned before that precoating your filter press can have several benefits for your dewatering process including:
Clearer end filtrate
Shorter, more consistent press cycles
Higher throughout per cycle
Dryer cakes that release more easily from filter cloths
