DEfiltreringssystemer
DEfiltreringssystemer, or diatomaceous earth filtration systems, are filtration units that use diatomaceous earth (DE) as a filtration aid or medium to remove suspended solids from liquids. They are used in municipal and industrial water treatment, beverage production, dairy and food processing, pharmaceuticals, wastewater treatment, and pool filtration.
How they work: A thin layer of DE is deposited on a supporting medium within the filter
Key components include the filter vessel with plates or grids, a controlled DE dosing system, a backwash
Applications and performance: DE filtration yields very clear filtrates and can retain sub-micron particles, making it
Advantages and challenges: DE filtration offers high filtration efficiency and versatility across liquids with varying turbidity.
Maintenance: Regular monitoring of differential pressure, timely backwashing, and re-coating with fresh DE are essential for
