Howes Pressure Leaf Filters

Job Engineered for Your Application

Where liquids/solids separation is required, Howes Pressure Leaf Filters provide either a dry or wet cake discharge for applications requiring flow rates up to roughly 1800 GPM and solids material composition up to 1% (or about 10,000 PPM). These units are ideal for high polish applications where 1/10 micron solids separation is required. In Howes Pressure Leaf Filters, a constant flow of material passes through a set of leafs contained within a ASME coded pressure vessel. The units can be designed using horizontal (large capacity) or vertical (lower capacity) configuration, automated or manual hydraulic shell retraction, and are constructed of mild or stainless steel or other exotic alloys. Pressure Nutsches are designed with a single leaf and are typically used for easily filtered materials or for lab/pilot applications because of their minimal throughput capacity. All equipment is custom designed for each application. Equipment is engineered and manufactured at the S. Howes plant in Silver Creek, NY and ASME coded vessels are constructed at West Metals Works – our sister company and code shop in Buffalo, NY. Let our application engineers help you specify the equipment configuration and leaf designs best suited to your unique processing requirements.

Wet Cake Pressure Leaf Filter (Sluice Design)
Where the filtration process produces a “wet cake”, the Howes Wet Cake Pressure Leaf Filter provides a multiple leaf configuration with an oscillating or hydro jet sluice filtrate discharge mechanism. Both horizontal and vertical tank configurations are available.

Dry Cake Pressure Leaf Filter Where the filtration process produces a “dry cake” or where sluicing is infeasible, the Howes Dry Cake Pressure Leaf Filter provides a multiple leaf configuration with a large filtration area and solids holding tank. A baffled inlet or internal distribution configuration is used as the feed arrangement. The dry cake is discharged by opening the tank shell and either manually or by vibration removing the solids. The liquid is discharged through a manifold on the discharge end. Both horizontal and vertical tank configurations are available.


Pressure Nutsches
The Pressure Nutsche provides pressurized or vacuum filtration for low throughput capacity and/or minimum floor space applications. Pressure and temperature can be controlled to accomplish thermal drying or reaction. A single leaf is used for the filter element and can be easily accessed for cleaning and replacement.
