Reinforced Ultrafiltration(UF) for River Water Purification with 0.03um pore size

Ultrafiltration or membrane filtration is a water filtration technology based on membranes and pressure to separate particles in suspension and colloidal matter from water.

Nominal diameter of micropores in ultrafiltration membranes is around 0.03 μm, what provides a good balance between filtration and permeability and provides a barrier against bacteria and most virus.

Current quality standards for water supplies in drinking and industrial applications have increased the use of ultrafiltration (membrane filtration), which delivers higher filtrate quality than conventional sand, gravel and anthracite pressure filters.

Ultrafiltration is also widely used as a in integrated membrane filters as pretreatment to reverse osmosis plants, reducing the RO membrane fouling risk and before water disinfection. By physically removing bacteria and pathogens ,ultrafiltration can also reduce significantly the downstream Chlorine dosing.

The main benefits of ultrafiltration opposed to other conventional filtration technologies are:

• Capacity to cope with variable feedwater quality, delivering a consistent filtrate independently of the feedwater characteristics
• Higher filtrate quality than tradicional sediment filters: 0.1 NTU and 99.999 bacteria removal
• Smaller plant footprint with up to 50% reduction compared to traditional media filters.
• Simpler design than standard media filters
• Lower chemical consumption and environmental impact than standard media filters

The whole installation and application process of our MBR modules are described as the following photo:

We,Hangzhou Kaihong Membrane Technology Co.,Ltd, is established on the year of 2003. We specializes in manufacturing UF and MBR membrane modules. We own more than 20 years of experience for the applying of UF and MBR membrane modules. Our products have been used in more than 1000 water treatment plants. We also have more than 2000 customers all over the world.

We have R&D team to develop new products and new separating technology for ourselves. We also have quality controlling system to ensure our products. At present our main products are made of PSF/PP/PVDF. We have hollow fiber membranes and flat sheet membranes for MBR systems. So we can meet different requirements for wastewater treatment and water purification.
