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.
