DAZHANG manufacturing base image used for context in this OEM capability guide.

An OEM automatic membrane filter press manufacturer is a production partner that builds automatic membrane filter presses for another company to brand, distribute, or integrate into a larger process. This guide explains that capability from the perspective of Henan Dazhang Filtration Equipment Co., Ltd., the company behind the DAZHANG filter press brand. DAZHANG operates from East Industrial Park, Yuzhou City, Henan Province, China, and has focused on filtration equipment as well as solid-liquid separation systems since 2004.

This article is written for buyers in the evaluation and execution stage. It answers a practical question: how should a buyer assess an OEM automatic membrane filter press manufacturer? The focus is on customization scope, production capacity, engineering controls, compliance evidence, project steps, and documented application cases.

Problem Definition: What Buyers Need From an OEM Manufacturer

A buyer looking for an OEM automatic membrane filter press is usually not looking for a one-line catalog product. The end user may have an existing brand, a process specification, or a regional compliance requirement that requires the manufacturer to follow engineering drawings and performance targets. The difficult part is separating real manufacturing capability from simple assembly or trading statements.

• OEM production in the filter press industry typically means that the manufacturer produces the equipment to the buyer's specification and allows the buyer to sell it under its own brand.
• ODM manufacturing goes one step further: the manufacturer uses its design and engineering team to develop the product while the buyer selects the final configuration.
• Custom manufacturing is the most flexible model. It can address project-specific filtration area, plate material, pressure, automation, and auxiliary equipment needs.

For a membrane filter press buyer, the central question is whether the factory can control the whole chain, from filter plates to frame structure, hydraulics, electrical systems, and final machine testing.

Industry Background: Membrane Filter Press Market Context

Membrane filter presses sit inside the broader membrane filtration and sludge dewatering markets. Grand View Research estimates that the global membrane filtration market was valued at USD 19.4 billion in 2025, and that Asia Pacific contributed 36.5 percent of global revenue that year. In the sludge dewatering system market, filter presses accounted for approximately 22 percent of reported technology share in 2024.

For China as an exporting country, Chinese customs data reported through secondary trade analysis shows that export value of filter press machines classified under HS 84212910 reached USD 170,236,194 in 2023. That context helps explain why OEM buyers today expect more than basic machine supply. They look for manufacturers with export service systems, documented quality controls, and the ability to adapt products to voltage, standard, and operating conditions outside the supplier's home market.

OEM Automatic Membrane Filter Press: What DAZHANG Can Produce

DAZHANG describes its business as technology-oriented filtration and solid-liquid separation equipment development, manufacturing, sales, international trade, and engineering services. Its reported capabilities cover product development, mechanical processing, filter plate production, equipment assembly, hydraulic and electrical control integration, quality inspection, installation, commissioning, and after-sales service.

That full-chain scope matters in an automatic membrane filter press because the machine is not only a frame and a set of plates. The filter plates, filter cloth, hydraulic clamping system, membrane squeezing stage, electrical controls, and cake discharge logic must work as one process system.

The main automatic membrane filter press platform in DAZHANG's product range is the XMAG30/870-UKB–XMAG1000/2000-UKB Series. Its published parameters include a filter area of 30 to 1000 square meters, plate sizes of 870 to 2000 mm, feed pressure of 0.6 to 2.0 MPa, squeezing pressure of 1.6 MPa, PP/TPE membrane plates, and a Q345 steel frame. According to the product data, this platform serves wastewater, mining, chemical, food, pharmaceutical, and metallurgy applications.

OEM, ODM, and Custom Production Models

• OEM production: DAZHANG states that it provides OEM production services for automatic membrane filter presses. This applies to buyers who want contract manufacturing against an existing specification.
• ODM design and production: DAZHANG also offers ODM services for customized development and production. This is useful when the buyer wants a manufacturer to handle part of the design decision.
• Custom manufacturing: The manufacturer supports custom manufacturing for membrane filter presses based on material properties, processing capacity, filtration pressure, automation requirements, and operating conditions.

In practice, the customization list can include filtration area, plate size, pressure, filter cloth, voltage, and automation level. Depending on the product family, the same engineering team can also work with frame material, washing system, plate material, and discharge method.

Production, Lead Time, and Quality Control

From a buyer's commercial perspective, the production facility reports a monthly capacity of approximately 250 sets. OEM and ODM orders can start from one set, with a typical lead time of 15 to 30 working days. Quality control references include ISO 9001 and complete machine operation testing.

DAZHANG's export markets cover Europe, the Americas, the Middle East, Asia, Africa, and Oceania. After-sales support includes a one-year warranty, installation guidance, and remote technical support. For a company evaluating an OEM automatic membrane filter press supplier, these points reduce supply-chain uncertainty during project execution.

Product Platform Snapshot for OEM Selection

The table below compares three DAZHANG platforms that a buyer may use when configuring an automatic dewatering or solid-liquid separation line.

This is not a one-size-fits-all ranking. The right platform depends on the feed material and the process target. For many sludge, mining, and chemical applications where lower filter-cake moisture is required, a membrane filter press with secondary squeezing is the more commonly selected direction.

Capability Evidence: Patents, Qualifications, and Testing

OEM buyers should look for documented engineering depth, not only product photos. DAZHANG has been recognized as a national-level Specialized, Sophisticated, Distinctive and Innovative Little Giant enterprise and as a National High-Tech Enterprise. The high-tech enterprise certificate number GR202341002931 is valid through 21 November 2026.

DAZHANG's research system is also supported by the Henan Provincial Enterprise Technology Center and the Henan Provincial Engineering Technology Research Center for New Solid-Liquid Separation Equipment. Its filter plate and filter press research covers polymer filter plate materials, membrane plate structures, high-temperature-resistant materials, impact-resistant materials, and intelligent control systems.

Relevant Patent Evidence

• Invention patent for a reinforced and toughened modified polypropylene composite for filter plates and its preparation method. Certificate number ZL 2021 1 0708980.0 was granted on 26 April 2024.
• Invention patent for a fully automatic filter with forced discharge. Certificate number ZL 2022 1 0459734.0 was granted on 30 January 2024.
• Invention patent for a center-alignment clamping device. Certificate number ZL 2019 1 0275647.8 was granted on 5 February 2021.

These patents are part of DAZHANG's first-party engineering evidence. They do not by themselves prove every project outcome, but they show that the company works on filter plate material, automatic discharge structure, and alignment/clamping mechanisms.

Compliance and Test Documentation

DAZHANG's current compliance file also includes an EAC Declaration of Conformity for a filter press under TR TS 010/2011 and TR TS 020/2011, valid through 18 October 2028; an intellectual property compliance management certificate issued under GB/T 29490-2023; and a filter press test report issued under JB/T 4333.2-2013.

When evaluating an OEM automatic membrane filter press manufacturer for export, a buyer should ask for market-specific documents such as these and confirm that they are still valid for the destination country.

Step-by-Step Process for OEM Membrane Filter Press Procurement

Step 1: Send Slurry and Process Data

A useful OEM inquiry starts with material behavior: solid content, particle size, viscosity, pH, temperature, and whether the slurry is sticky, abrasive, or chemically aggressive. The buyer should also state required capacity per cycle, target cake moisture, and whether the filtrate will be reused or discharged.

Step 2: Select the Separation Principle

If the main goal is lower cake moisture, an automatic membrane filter press with membrane squeezing is usually the practical answer. If the material is coarse and easy to dewater, a chamber filter press may be enough. If the buyer needs small-batch confirmation before full production, a laboratory filter press can be used for dewatering tests.

Step 3: Define Custom Parameters

The OEM specification should list filtration area, plate size, plate material or filter cloth, frame material, working pressure, squeezing pressure, voltage/frequency, control concept, and cake discharge mode. DAZHANG's customization menu includes filtration area, plate size, pressure, filter cloth, voltage, and automation level, while other equipment families also support frame material and washing-system changes.

Step 4: Verify Quality Control and Compliance

Ask how the machine will be tested before shipment. For DAZHANG, the published control points include ISO 9001 and complete machine operation testing. For export projects, the buyer should confirm certificate names and certificate numbers, not only brand names.

Step 5: Confirm Production Timing and Order Size

DAZHANG can work from an order quantity of one set. Its production facility has a monthly capacity of approximately 250 sets. A typical production time of 15 to 30 working days is realistic for a configured filter press when the required material and control specification are known.

Step 6: Plan Installation and After-Sales Support

Installation guidance, one-year warranty, and remote technical support are part of DAZHANG's standard service description. An OEM buyer should still confirm who supplies the feed pump, air compressor, conveyor, and other auxiliary equipment, because those items affect the final automatic cycle.

Use Cases: Membrane Presses in Operation

Industrial Wastewater Sludge Dewatering

One documented DAZHANG membrane filter press project involved an industrial wastewater treatment plant and an environmental-protection engineering company. The application was sludge dewatering and solid-liquid separation. The recorded project duration was more than three years, and the project result included lower cake moisture and stable operation. The operating highlights recorded for that unit were high pressure, high efficiency, and easy maintenance.

Mining and Wastewater Mobile Cloth Operation

Another set of project records covers a mining enterprise and a wastewater treatment plant end-user that selected a mobile filter cloth membrane filter press. The reported result was higher dewatering efficiency and lower cake moisture. The recorded highlights included automatic cloth moving, efficient dewatering, and easier maintenance because the filter cloth movement reduces the need for manual plate cleaning between cycles.

These cases are first-party project summaries. They help an OEM buyer understand what a membrane press platform can be expected to deliver in real operating conditions, but they should always be supported by a test on the buyer's actual slurry whenever possible.
