LEFILTER introduces the MR-1812-75 Ultrafiltration Membrane, a high-performance solution engineered specifically for industrial wastewater treatment applications. Developed as a reliable equivalent to Morui’s membrane technology, this compact yet powerful module delivers outstanding filtration efficiency, chemical resistance, and long-lasting performance even in harsh industrial environments. It is designed for operations requiring precise separation, consistent water quality, and minimal maintenance—making it ideal for integration into modern wastewater recovery and recycling systems.
Product Overview
The MR-1812-75 is constructed using premium polyethersulfone (PES) hollow fiber membrane material, offering a nominal pore size of 0.03 microns. This allows for the effective removal of suspended solids, bacteria, colloids, and certain organic matter, ensuring clean effluent suitable for reuse or discharge. Its structural durability and compatibility with various industrial chemicals make it a smart choice for high-contaminant environments, especially in mid- to small-scale modular filtration systems.
This ultrafiltration membrane fits standard pressure housings and is designed for outside-in flow configuration, maximizing filtration surface area and simplifying cleaning processes. Whether you're upgrading an existing Morui-based system or building a new treatment line, the MR-1812-75 provides seamless adaptability with superior economics.

Application Fields
The MR-1812-75 Ultrafiltration Membrane is specifically developed for demanding wastewater environments where high solids loading, fluctuating pH, and chemical exposure are common. Key application sectors include:
● Metal Processing & Precision Manufacturing
Efficient removal of emulsified oils, metallic particulates, and polishing fluids from wastewater streams. Facilitates water recycling and compliance with discharge regulations.
● Textile & Dyeing Industry
Captures fine fiber particles, residual dyes, and auxiliaries in effluents, making it suitable for tertiary treatment or RO pre-filtration stages.
● Pharmaceutical and Chemical Plants
Used for removing bacteria, organic compounds, and colloids from process water and wastewater, helping to meet strict environmental and production hygiene standards.
● Plating and Surface Treatment Facilities
Ideal for filtration of degreasing water, rinse water, and chemical baths with high contaminant content, enabling water reuse and reduced operational costs.
● Zero Liquid Discharge (ZLD) and Resource Recovery
Supports membrane bioreactors (MBR) and final-stage polishing processes in ZLD systems, contributing to efficient water reclamation strategies.
FAQ
Q1: Can the MR-1812-75 replace Morui membranes in existing housings?
A1: Yes, the MR-1812-75 is fully compatible with standard Morui housings, offering a plug-and-play replacement option without requiring system redesign.
Q2: Is the MR-1812-75 suitable for high-COD wastewater?
A2: Absolutely. The PES membrane structure resists fouling and degradation in environments with moderate to high organic loads, making it ideal for such industrial wastewater streams.
