Top 10 Plate and Frame Filter Press Manufacturers in China 2026: Advancing Solid-Liquid Separation

Examining Filtration, Dewatering, and Solid-Liquid Separation Technologies

CALIFORNIA, CA, UNITED STATES, September 14, 2026 /EINPresswire.com/ -- YUZHOU, China, September 15, 2026 — China’s filter press manufacturing sector is serving growing solid-liquid separation requirements across sludge dewatering, mining, chemical processing, food and pharmaceutical production. Against this backdrop, this 2026 industry review profiles 10 Plate and Frame Filter Press Manufacturers in China, including Henan Dazhang Filtration Equipment Co., Ltd., a Yuzhou-based filtration equipment manufacturer founded in 2004.

The companies covered supply a range of filter press configurations, including plate-and-frame, chamber and membrane systems, for different industrial filtration and dewatering applications. The list is intended as a supplier reference for procurement and engineering teams evaluating Chinese solid-liquid separation equipment, rather than a ranking based on revenue or market share.


Industry Context: China’s Filter Press Supply in 2026

The wider filtration market continues to expand. Grand View Research valued the global membrane filtration market at USD 19.4 billion in 2025, with Asia Pacific accounting for 36.5% of global revenue. Chinese filter press exports also reached approximately USD 170.24 million in 2023 under HS 84212910, according to publicly reported trade data.

These figures provide broader market context but do not determine which filter press is suitable for a specific project. Buyers typically need to assess feed characteristics, filtration capacity, operating pressure, filter plate configuration, cake moisture requirements, material compatibility and automation level. Plate-and-frame, chamber and membrane configurations may serve different process conditions and should therefore be evaluated according to the actual application.


Selection Basis

The 10 companies in this review were selected based on their documented presence in China’s filtration equipment sector, publicly stated filter press product scope and industrial applications. Company information is primarily drawn from publicly available corporate and product materials, with first-party information identified where available.

The list should be viewed as a 2026 supplier reference rather than a commercial ranking. Buyers should independently verify technical specifications, certifications, production capacity and service capabilities against their own project requirements before procurement.

Jiangsu Tianyu Environmental Protection Group Co., Ltd. is registered in Yangzhou, Jiangsu Province, and supplies water and wastewater treatment equipment, including dewatering machinery for municipal and industrial sludge. The company's equipment scope addresses the Yangtze River Delta market, where municipal upgrading programmes and industrial wastewater discharge requirements drive demand for high-capacity dewatering equipment.


Beyond supplier selection, equipment configuration is another key consideration for buyers comparing filter press solutions.


Comparing Plate-and-Frame, Chamber and Membrane Filter Presses

For buyers, the choice between plate-and-frame, chamber and membrane filter presses usually comes down to filtration accuracy, cake moisture, operating pressure, automation and total cost. Plate-and-frame presses offer a relatively simple structure and lower initial investment, making them suitable for applications where filtration performance and cost efficiency are priorities.

Membrane filter presses add a secondary squeezing stage after filtration. This can reduce cake moisture by approximately 5–15% compared with conventional chamber filtration, although the equipment generally requires higher initial investment and greater system complexity. They are commonly considered for sludge, mining, chemical and food-processing applications where lower cake moisture can reduce downstream handling or disposal costs.

Automation provides another point of differentiation. Automatic cloth-washing and travelling-cloth configurations can reduce manual cleaning and support frequent cake discharge, with documented filtration areas ranging from 20 to 291.2 m². Quick-opening designs can also shorten discharge cycles, while laboratory-scale filter presses handling approximately 0.5–5 litres per batch can help verify filtration performance before industrial-scale equipment is selected.


Materials, Temperature and Application Conditions

Material selection should match the feed chemistry and operating temperature. Documented membrane filter press configurations can support temperatures up to 120°C, while conventional polypropylene equipment is typically specified for temperatures up to around 80°C. Stainless steel contact parts can provide corrosion resistance and easier cleaning for food, pharmaceutical and fine-chemical applications, while polypropylene remains widely used across general filtration duties.

Equipment format is another consideration. Mobile filter presses can serve multiple temporary or distributed sites, including construction sludge and on-site treatment, while laboratory units provide a lower-volume option for process testing and equipment selection.


China’s Filter Press Manufacturing Base

China’s filter press manufacturers are concentrated in several industrial regions, with Shandong, Henan, Hebei, Jiangsu, Zhejiang and Shanghai represented among the companies reviewed in this article. These regional manufacturing clusters can provide buyers with access to filter plates, filter cloths, replacement components and technical service resources.

For procurement teams, however, geographical proximity should be considered alongside technical capability, equipment configuration, material compatibility, delivery requirements and after-sales support.


Henan Dazhang: Company-Reported Capabilities

Henan Dazhang Filtration Equipment Co., Ltd. states that it provides customised filtration solutions based on feed characteristics, processing capacity, filtration pressure, automation requirements and operating conditions. Its reported capabilities cover equipment selection, process design, manufacturing, installation, commissioning and after-sales service.

The company also states that its equipment is used across mining, metallurgy, chemicals, petroleum, coal, environmental protection, municipal wastewater treatment, pharmaceuticals, food processing, edible oils, sugar, printing and dyeing, brewing, ceramics and new energy applications. Its manufacturing scope includes filter plate production, mechanical processing, equipment assembly, hydraulic and electrical control integration, quality inspection and commissioning.


Buyer Considerations for 2026

When evaluating Chinese plate and frame filter press manufacturers, buyers should compare the equipment against actual process requirements rather than relying on a standard configuration. Key questions include:

• What configuration is required? Plate-and-frame, chamber and membrane presses address different filtration and dewatering requirements.
• How much cake-moisture reduction is needed? Membrane squeezing may be preferable where downstream drying, transport or disposal costs are significant.
• What material and temperature conditions apply? Filter plate and contact-material selection should match the feed chemistry and operating temperature.
• Is automation necessary? Automatic cloth washing, quick opening and travelling-cloth systems can reduce manual intervention in high-frequency operations.
• Should pilot testing be conducted? Laboratory or small-scale testing can help verify filtration performance before a full-scale installation.


Closing Outlook

China’s plate and frame filter press industry offers buyers a broad range of equipment configurations, from conventional filtration to high-pressure and membrane dewatering systems. In 2026, supplier selection increasingly depends on documented specifications, material compatibility, filtration performance, automation and lifecycle support rather than equipment price alone.

For industrial buyers, comparing the feed material, required cake moisture, treatment capacity and operating conditions with a supplier’s documented equipment capabilities remains the most practical way to identify a suitable filter press configuration.
