Dongou takes the lead in drafting China’s first National Standard GB/T 47900-2026 for Polymer Sintered Microporous Membrane Elements, filling a long-standing gap in the microfiltration industry.

Core Highlights:
1. Unified classification & model coding for tubular & flat-sheet membranes.
2. Standardized test methods covering pore size, flux, corrosion resistance, mechanical strength, and more.
3. Tiered performance standards for different membrane materials.

This standard is set to drive quality upgrades and strengthen the competitiveness of China's membrane industry.

With 40+ years of microfiltration expertise, Dongou delivers custom-engineered precision filtration solutions for global industrial partners.

Exciting exchange at Dongou Filter! 🌍

Last week, we hosted Professor Heba and a delegation from Egypt's National Research Centre (NRC), thanks to Zhejiang University. It was a fantastic opportunity to showcase our 40 years of expertise in microfiltration, tour our production lines, and discuss potential collaborations on advanced membrane technologies.

We're excited about the future of this partnership and the shared goal of advancing filtration solutions worldwide.

That's a wrap on the 7th Lithium Latin America Congress in Buenos Aires.

Honored to share our filtration solutions for the full lithium chain – from brine to cathode.

The highlight? One-pass solid-liquid separation. No filter aid. No complexity.

Grateful for the great conversations and connections.

Thank you to Vostock Capital UK for organizing this valuable event.
