An open-type rotary screening system for efficient solid-liquid separation, low operating cost, and partial dewatering of retained solids.
Product Overview
The Internally Fed Rotary Drum Filter, also known as an Internal-Feed Rotary Drum Filter or Inner Water-Inlet Rotary Drum Filter, is an open-type rotary screening system designed for solid-liquid separation in wastewater pretreatment and industrial screening processes.
Wastewater enters the inside of the rotating drum through the inlet pipe. As the drum rotates, liquid passes through the drum slots or fine screen openings, while solid particles are retained inside the drum. The retained solids are conveyed along the inner surface of the drum toward the discharge end and are partially dewatered before discharge.
This equipment is suitable for applications requiring stable screening, low operating cost, low cleaning cost, and partial dewatering of separated solids. An external washing system and automatic control system can be configured according to project requirements.
Typical Process Flow:
Raw Wastewater → Internally Fed Rotary Drum Filter → Screened Water Outlet → Equalization Tank → DAF / Clarifier → Biological Treatment → Discharge or Reuse
This product is a professional sewage treatment solution developed for [target sewage types such as municipal domestic sewage/industrial organic wastewater/breeding wastewater/medical wastewater]. Integrating [core technologies such as biological treatment/membrane separation/advanced oxidation/intelligent control], it can efficiently remove pollutants including COD, BOD, ammonia nitrogen, total phosphorus, suspended solids, and toxic and harmful substances from sewage. With core advantages of [small footprint/low operating cost/high treatment efficiency/easy operation and maintenance], the product is widely applicable to [application scenarios such as urban communities, industrial parks, livestock and poultry farms, medical institutions, scenic spots]. The treated effluent can meet [specific standards such as GB18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (Grade 1A) / local customized discharge standards], realizing harmless discharge or resource recycling of sewage
Core Advantages
- Efficient Solid-Liquid Separation
Fine screen openings retain solid particles and improve screening performance. - Internal-Feed Screening Design
Wastewater enters the center of the drum, and solids are retained inside the rotating drum. - Partial Solids Dewatering
Retained solids are conveyed inside the drum and partially dewatered before discharge. - Low Operating and Cleaning Cost
Open-type rotary structure supports stable operation with low daily operating cost. - Optional External Washing System
Helps clean the screen slots and maintain stable filtration performance. - Automatic Control Option
Can be equipped with an automatic control system for easier operation and monitoring.
- Efficient Purification & Compliance Assurance
Adopting [core technology name], it can rapidly decompose complex pollutants in sewage with a pollutant removal rate of up to [specific percentage, e.g., over 95%], ensuring stable compliance of effluent quality and strong adaptability to fluctuations in water quality. - Energy Conservation, Environmental Protection & Cost Control
Designed in line with energy-saving concepts, the equipment/agent [e.g., uses low-power motors/zero chemical addition with biological strains/circulating treatment process], significantly reducing energy consumption and chemical costs during operation. It also minimizes sludge production and lowers solid waste disposal expenses. - Flexible Adaptation & Easy Installation
To meet diverse scenario requirements, it offers [modular assembly/mobile deployment/customized configuration] solutions, occupying only [specific ratio, e.g., 60%] of the area of traditional processes. Whether for new projects or renovation of old facilities, installation and commissioning can be completed quickly. - Intelligent Management & Hassle-Free Operation
Equipped with [intelligent sensors/Internet of Things (IoT) monitoring platform/automatic dosing system], it can real-time monitor water quality indicators and equipment operating status, supporting remote control and fault early warning. No on-site personnel are required, reducing the threshold for manual operation and maintenance. - Green Sustainability & Resource Recycling
The treated effluent can be used for [farmland irrigation/landscaping irrigation/industrial cooling water/municipal miscellaneous use] as needed, realizing water resource recycling. Sludge can be converted into [organic fertilizer raw materials/biomass fuel] after further treatment, aligning with green development concepts.
