The Seitz T Series Depth Filter Sheets were developed for coarse and clarifying filtration of many fluids in the food and beverage industry. The reduced density and high porosity media make this media suitable for filtration of viscous materials, retaining gel particles, or coarse dispersed substances at low differential pressures. Available in multiple formats.
From the selection and quality control of raw materials to the application of the latest production technologies, the T Series Filter Sheets meet the highest quality standards:
Homogenous and consistent media offer proven and reliable performance
An economic filtration with high particle holding capacity resulting in long filtration cycles and high throughputs
Each individual filter sheet is laser etched with the sheet grade, batch number and production date for full traceability

These figures have been determined in accordance with in-house test methods and the methods of the Technical /Analytical Work Group within the European Depth Filtration Association.
2The permeability was measured under test conditions with clean water at 20 °C (68 °F) and a Δp of 1 bar (14.5 psi).
Regeneration
T Series Filter Sheets may be rinsed with clean water (in the forward or reverse direction) to increase throughput and to optimize economic efficiency. Optimal regeneration of filter sheets installed in a plate and frame filter may be achieved with serial rinses of warm water followed by hot water. An example protocol is shown below.
Rinse with warm water (60 °C / 140 °F) for 15 minutes
Rinse with hot water (70 – 80 °C / 158 – 176 °F) for 8 – 10 minutes
The rinse flow rate should be equivalent to the filtration flow rate with a back pressure of 0.5 –1 bar (7.2 –14.5 psi).
