Rotary Drum Thickener

Rotary drum thickening increases the sludge solids concentration (i.e. thickens the sludge) by agitating the solids in a slowly-rotating vessel with porous walls though which the water (or filtrate) drains.cRotary drum thickening increases the sludge solids concentration by agitating the solids in a slowly-rotating cylindrical drum with porous walls though which the water (or filtrate) drains. The rotary screen is a drum sieve loaded from inside for separating suspended solids, particles and fibres from liquids, process water and waste water. The rotary drum can be equipped with different types of sieves or filters like perforated metal plates, wedge wire screens and fabrics.
