Pressure Leaf Filters

Durco Filters Pressure Leaf Filters are designed for high flow rates and batch operations in applications with <2% solids loadings.Pressure Leaf Filters are pressure vessels containing permanent filter leaves. These leaves can be the final filtration media but typically use Diatomaceous Earth (DE) as a pre-coat and/or body feed to improve filtration rate and product clarity. High flow rates are easily accommodated as flux rates (flow per unit area) may be as high as 2 gpm/sq ft filter area.

Pressure Leaf Models

Horizontal Vessels Most typical configuration. Used when maximum surface area for filtration is required

Nutsche Filters Used when the cake is the product and needs to be recovered Allows multiple steps including cake washing in one vessel
