Product Introduction
GTS Series Internally Fed Rotary Drum Screen Manufacturer - Efficient Solid-Liquid Separation for Reliable Wastewater Pretreatment
The GTS Series Internally Fed Rotary Drum Screen is a highly efficient mechanical screening system designed to remove suspended solids, fibers, plastics, organic debris, and other coarse particles from municipal and industrial wastewater. Featuring an internally fed rotary drum design, the system ensures uniform water distribution, continuous screening, and automatic cleaning, significantly reducing downstream equipment wear while improving the overall efficiency of wastewater treatment plants.
Designed for continuous operation, the GTS series rotating drum screen combines high screening efficiency, low energy consumption, compact footprint, and minimal maintenance, making it an ideal pretreatment solution for new wastewater treatment facilities and existing plant upgrades.
Manufactured with high-quality SS304 or SS316 stainless steel, the equipment offers excellent corrosion resistance and long service life in demanding environments. Whether your project involves municipal sewage, food processing wastewater, textile effluent, paper mill wastewater, slaughterhouse wastewater, or industrial process water, BioCell provides customized rotary drum screening solutions tailored to your flow rate, screening aperture, and installation requirements.
What Is A GTS Series Internally Fed Rotary Drum Screen?
The GTS series internally fed rotary drum screen is an automatic mechanical screening device used as the first-stage pretreatment equipment in wastewater treatment systems. Wastewater enters the interior of the rotating drum, where solids larger than the screen openings are retained on the inner surface while clean water passes through the perforated or wedge wire screen.
As the drum rotates continuously, captured solids are transported toward the discharge end. An integrated spray washing system cleans the screen surface to prevent clogging, ensuring stable performance and uninterrupted operation.
Compared with conventional bar screens, internally fed rotary drum screens provide:
● Higher screening efficiency
● Better removal of fine suspended solids
● Lower maintenance requirements
● Continuous automatic operation
● Reduced odor generation
● Improved downstream treatment performance
How Does an Internally Fed Rotary Drum Screen Work?
The GTS Series Rotary Drum Screen operates through a simple yet highly efficient continuous screening process.
Step 1 - Wastewater Feeding: Wastewater enters the inlet chamber and flows into the interior of the rotating drum.
Step 2 - Mechanical Screening: Water passes outward through the screen openings while solids larger than the aperture remain inside the drum.
Step 3 - Solid Conveying: The rotating drum transports retained solids toward the discharge end.
Step 4 - Automatic Washing: A high-pressure spray system continuously cleans the screen surface, preventing clogging.
Step 5 - Solid Discharge: Screenings are discharged automatically for further dewatering or disposal.
Step 6 - Clean Water Outlet: Filtered wastewater flows to the next treatment process.
