2. Industry Context for Membrane Filter Press Manufacturers

Global demand for membrane filtration technology has expanded significantly. According to Grand View Research, the global membrane filtration market was valued at approximately USD 19.4 billion in 2025. The same source reports that Asia Pacific accounted for the largest regional share of the membrane filtration market at 36.5% in 2025. This regional concentration makes Chinese filtration equipment manufacturers relevant to international sourcing decisions.

China is also a notable exporter in this category. China Customs data reported in 2024 shows that Chinese export value of filter press machines under HS code 84212910 reached USD 170,236,194 in 2023. In the sludge dewatering segment, filter presses account for approximately 22% of the global sludge dewatering system market based on one market analysis. For a membrane filter press manufacturer such as DAZHANG, these conditions explain why buyers increasingly compare china-based suppliers on engineering capability, automation level, certifiable manufacturing processes and international service ability.

3. Core Products and Solutions

3.1 Automatic Membrane Filter Press Series

DAZHANG's automatic membrane filter press is designed for solid-liquid separation in sludge dewatering applications. The product series spans model XMAG30/870-UKB through XMAG1000/2000-UKB, with a filter area ranging from 30 to 1000 square meters and plate sizes from 870 to 2000 mm. Feed pressure operates between 0.6 and 2.0 MPa, while the membrane squeezing pressure reaches 1.6 MPa. The equipment is constructed with PP/TPE membrane plates and a Q345 steel frame.

The membrane filter press is applied in wastewater treatment, mining, chemical processing, food production, pharmaceuticals and metallurgy. Its core value comes from high-pressure squeezing after cake formation, which lowers cake moisture content and improves dewatering efficiency compared with standard chamber filtration. For users in sludge treatment, mining tailings, chemical slurries and food processing, this automatic membrane filter press offers a reliable route to higher dryness and shorter filtration cycles.

DAZHANG also supplies a mobile filter cloth membrane filter press in 1100 and 1500 series sizes. This automatic membrane filter press provides filter areas from 20 to 291.2 square meters, filtering pressure from 0.6 to 4.0 MPa, automatic cloth traveling and automatic cleaning. It is designed for mining, coal, metallurgy, chemical, power and sludge treatment industries where continuous operation and low manual intervention are required.

3.2 Supporting Filter Press Product Line

Beyond membrane filter presses, DAZHANG offers a full portfolio that allows project-specific matching. The XMAY series recessed chamber filter press has a filter area of 30 to 1000 square meters and filtration pressure from 0.6 to 4.0 MPa, with PP filter plates and a Q345 carbon steel frame. It is used across chemical, wastewater, mining, metallurgy, food and pharmaceutical industries.

The XMZG50/1000-U once-open filter press is designed for automatic cake discharge in wastewater, mining, metallurgy, chemical, coal and food processes. Its automatic once-open plate movement shortens the discharge phase and supports higher daily throughput. The 320-2000 series water-flush filter press provides automatic high-pressure water flushing to keep filter cloths clean, improve filtration efficiency and reduce manual labor in sludge dewatering and industrial slurry applications.

For applications requiring sanitized filtration, DAZHANG manufactures stainless steel plate and frame filter presses and the Automatic Hydraulic Stainless Steel Plate and Frame Filter Press for the pharmaceutical, beverage, juice, oil and fine chemical sectors. The company also covers fine filtration needs with plate and frame filter presses, cotton cake filter presses, candle filters, bag filters and cartridge filters. This product breadth lets buyers consolidate equipment sourcing under one filtration partner.

3.3 Customization and Engineering Service

DAZHANG provides customized filtration solutions based on customers' material characteristics, processing capacity, filtration pressure, automation requirements and operating conditions. Rather than applying generic equipment, the company supports process development through equipment selection, process design, manufacturing, installation, commissioning and after-sales service. That engineering service model is especially useful when the material is corrosive, viscous or temperature-sensitive.

4. Manufacturing Strength and Technical Capability

DAZHANG has built an integrated production system covering product development, mechanical processing, filter plate production, equipment assembly, hydraulic and electrical control system integration, quality inspection, installation, commissioning and after-sales service. This vertical integration is important for industrial filter press buyers because it reduces dependency on third-party component supply and shortens problem-solving paths during commissioning.

The company's research and development capabilities include 45 professionals dedicated to filtration technology innovation. DAZHANG has established a professional R&D system supported by the Henan Provincial Enterprise Technology Center and the Henan Provincial Engineering Technology Research Center for New Solid-Liquid Separation Equipment. These platforms support R&D in filtration equipment, polymer filter plate materials, membrane filter plate structures, intelligent control systems, high-temperature-resistant materials and impact-resistant materials.

In core filtration components, DAZHANG independently developed a processing-free sealed square polypropylene filter plate and obtained related invention patent protection. The product has entered the European market. The company has also developed high-temperature-resistant and toughened PP polymer filter plates, while its differentiated polymer filter plate project received a second prize in a 2022 “Maker in China” competition. Buyers evaluating membrane filter press manufacturers can interpret these milestones as evidence of material-level research rather than only assembly-level production.

DAZHANG actively participates in filtration-related technical standardization and continues to expand its portfolio of patents, proprietary technologies and independent intellectual property. Factory-level quality control is supported by large-scale production space, in-house filter plate molding, hydraulic system integration and final equipment testing before shipment.

5. Market Recognition and Industry Position

DAZHANG has been recognized as a national-level Specialized, Sophisticated, Distinctive and Innovative “Little Giant” enterprise and a National High-Tech Enterprise. These designations reflect company focus, continuous innovation and technology specialization in the filtration equipment industry. DAZHANG has also received honors related to energy conservation and environmental protection, as well as provincial-level brand recognition.

The company serves customers in more than 100 countries across Asia, Europe, Africa, South America, North America, the Middle East and Oceania. It has implemented a global development strategy and established an international trade and overseas service system, with overseas subsidiaries, domestic companies and international business teams supporting product consultation, technical support, project implementation and after-sales service. These are material inputs for a buyer checking whether a membrane filter press manufacturer can support long-distance projects.

DAZHANG's manufacturing and engineering experience spans mining, chemical processing, environmental protection, municipal wastewater treatment, food processing and industrial production. It uses this experience to provide tailored equipment configurations for varying materials and filtration duty conditions, which is a practical differentiator when evaluating supplier fit.
