We are a manufacturer of high quality environmental protection equipment in China.
QXZL610×1220 is an efficient and automated sewage treatment equipment designed for industrial and municipal wastewater treatment. It uses a rotary drum filter structure and is equipped with a stainless steel filter screen to effectively intercept suspended matter, fiber and other impurities, with high filtration accuracy (0.2-3mm optional) and a processing capacity of 50-200m³/h. The equipment integrates an automatic cleaning system to remove filter residues through high-pressure spraying.
Advantages include: fully automated control, low energy consumption, corrosion-resistant materials (304/316 stainless steel), compact structure and modular design, suitable for a variety of sewage scenarios (such as papermaking, food, chemical industry, etc.).
Equipment Advantages:
1) The screen of the drum filter is self-cleaning during the operation of the equipment, it operates slowly, the screen does not get clogged, runs smoothly, has low energy consumption, low noise, small grid gaps, and with the aid of fluid guidance, the equipment's separation efficiency can reach up to 97%.
2) The upper cover of the drum filter is detachable, making the installation of the screen very convenient, and the joint parts are sealed with rubber to prevent leakage at the joint surfaces and the input and output shaft seals.
3) The drive unit is located on one side of the drum filter, and the reducer is directly connected to the drum shaft, which makes the operation flexible, smooth, and reliable without abnormal noise. The drive unit uses a high-quality reducer, and all the joints of the gearbox are sealed reliably to effectively prevent the entry of water and dust and the leakage of lubricant. The reducer uses well-known brand products.
4) The supporting bearings on both sides of the drum filter have good working characteristics, stable operation, and a long service life.
5) The drum filter has sufficient strength and rigidity under the conditions of high water level difference inside and outside.
6) The drum filter is equipped with a backwashing device, and the position of the washing device can be adjusted.
7) The cleaning mechanism consists of scrapers, support frames, springs, etc., which can achieve a more thorough cleaning. The buffering effect of the springs, it prevents the drum and scraper from jamming during the cleaning process, making the design more reasonable.
8) The operation interval and running time can be adjusted arbitrarily to achieve the function of periodic operation.

The Automatic Rotary Drum Filter Machine is a mechanical filtration unit designed for continuous solid-liquid separation in wastewater treatment processes. By utilizing a rotating drum covered with a precision stainless steel wedge wire screen or woven mesh, this equipment effectively removes suspended solids, fiber debris, and micro-particles from influent streams. The system operates on a gravity or pressure-fed principle, ensuring automated self-cleaning through an internal backwash mechanism that maintains filtration efficiency without manual intervention.
The core of the rotary drum filter consists of a cylindrical drum that rotates at a controlled speed. As the effluent enters the drum, liquid passes through the filtration media while solids are retained on the inner surface. A high-pressure spray bar positioned at the top of the drum clears the trapped debris into a collection hopper. This process is critical for primary sewage clarification and the protection of downstream biological treatment stages from clogging.

This equipment is engineered for diverse industrial wastewater pretreatment scenarios. It is extensively utilized in aquaculture drum filter systems for fish farm water recirculation, as well as in pulp and paper mill effluent treatment for fiber recovery. Other applicable sectors include food processing plant filtration, municipal sewage works, and textile printing and dyeing facilities where high-load solid separation is mandatory.
For applications involving high oil or grease content, such as in the slaughterhouse or food processing industries, the drum filter is often integrated with a hot water backwash system. This prevents the blinding of the filter mesh. As an established industry-and-trade enterprise, Yangzhou Qinxin Environmental Protection Technology Co., Ltd. provides customized filtration solutions. Our expertise extends beyond drum filters to stacked screw sludge dewatering machines and PAM integrated dosing devices, ensuring that oily residues are managed effectively within a comprehensive treatment train. Our equipment is manufactured under AAA-level contract-oriented standards to ensure reliability in harsh environments.
Maintenance is minimized due to the self-cleaning rotary design. Routine checks include inspecting the spray nozzles for clogging and monitoring the drive chain lubrication. Yangzhou Qinxin Environmental Protection Technology Co., Ltd. designs these systems with a focus on longevity, backed by multiple patents and ISO quality management system certifications. We serve a global market, with a significant portion of our annual production exported to Southeast Asian countries. Our technical team supports clients across petrochemical, pharmaceutical, and municipal sectors, ensuring that spare parts like solid-liquid separator screens are readily available to maintain continuous operation.
The rotary drum filter serves as a compact alternative to primary clarifiers or large sedimentation tanks, occupying significantly less floor space while providing more consistent solids removal. It is particularly effective as a micro-screening solution for pre-treating influent before it enters sludge low-temperature drying systems or biological reactors. Yangzhou Qinxin Environmental Protection Technology Co., Ltd. leverages years of practical research and development to supply integrated equipment packages—including sewage treatment equipment for aquaculture, leather, and brewing industries—that optimize plant footprint and operational efficiency.
Products provided by famous enterprises are deeply trusted by users.
