Easy filterable applications with large capacities are well served by continuous filters, like Rubber Belt Filters and Drum filters.  Cake heights are usually high, like 5 cm but also higher is seen.

 

Another range of applications served by continuous filters are those that have long filtration times at higher cake heights. These applications can run at reasonable filtration rates at lower cake heights up to 1 or 2 cm.  They are also called thin cake filters. 

 

All of these filters are fed continuously and also discharged continuously without stopping the feed.

 

Cake wash is excellent on horizontal belt filters but also possible on drum filters, though less efficient.  Both Belt and Drum filters allow mechanical squeeze dewatering by mechanical pressure sections towards discharge end.  Final drying is sometimes possible on belt filters by means of steam injection, hot air or IR.
