How rotary drum thickening works. 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.. A rotary drum thickener (RDT) is based on the same principle as a gravity belt thickener (GBT), in that water drains from …
— Rotary drum screens, also known as rotary sifters, play a pivotal role in municipal and industrial water treatment processes. Positioned as the second pre-treatment step after initial screening, these devices are typically placed upstream from the main system, specifically at the discharge point of the wastewater collection pumping station.
