Huamo HM4046/HM90 Hollow Fiber UF Membrane
Huamo HM4046/HM90 hollow fiber ultrafiltration membrane module uses advanced internal/external pressure membrane separation technology. Operating at ambient temperature and low pressure, it offers low energy consumption, high filtration precision, large permeate output, and strong fouling resistance — effectively removing bacteria, colloids, suspended solids, rust, and macromolecular organic matter.
- Low energy consumption
- High filtration accuracy
- Large water output
- Strong anti-fouling
UF Membrane Filtration Principle
Huamo hollow fiber ultrafiltration membrane modules employ advanced internal and external pressure membrane separation technology. Operating at ambient temperature and low pressure, they offer low energy consumption, high filtration precision, large permeate output, and strong fouling resistance. These modules effectively remove bacteria, colloids, suspended solids, rust, and macromolecular organic matter from water, producing clean, safe permeate.

Application Areas
The HM4046/HM90 hollow fiber UF membrane module is widely applied in municipal drinking water treatment, industrial process water purification, residential water supply, food and beverage processing, pharmaceutical water production, and wastewater recycling. It provides reliable 0.01-micron filtration for pre-treatment before RO systems and standalone water purification applications.
Important Notes
- Before installation, do not drain the protective liquid inside the membrane. Hollow fiber membranes lose performance if dried out. During temporary shutdown, keep the module filled with clean water to maintain moisture.
- In cold climates, take precautions to prevent freezing of the membrane module.
- The UF module housing is made of plastic. Handle carefully to avoid cracking from drops or impact.
- At connection points, avoid contact with oils, greases, or contaminants beyond the designated adhesive.
- During initial operation, flush the module for at least 30 minutes to remove residual preservative before collecting permeate for use.
