Industrial ultrafiltration (membrane filtration) is the best alternative to traditional sediment filters based on sand and anthracite media filtration.
Delivering consistent turbidity, bacteria and virus removal using only a fraction of the existing footprints, ultrafiltration is replacing many conventional water filtration plants in groundwater and industrial water applications.

1. Commercial and industrial ultrafiltration (membrane filtration)

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.

Ultrafiltration filtering range

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.

2. ultrafiltration benefits

Industrial Ultrafiltration barrier for turbidity and bacteria

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

Industrial Ultrafiltration system parts and configuration

3. typical recovery rates in ultrafiltration systems

The recovery rate of a typical Ultrafiltration (membrane filtration) system is the permeate volume divided by the feedwater volume for a period of time.

Permeate water used for backwashing and flushing must be considered for the overall system recovery. Typical recoveries for ultrafiltration systems range from 85 percent to greater than 95 percent.

Design recovery typically decreases as feedwater turbidity increases and, in some cases, recovery and plant capacity are constantly monitored and controlled to match the feedwater quality.

1% to 15 % of the daily filtrate flow will typically be required for backwash and membrane flushing in any industrial ultrafiltration (membrane filtration) plant.

4. Ultrafiltration plants with multiple configurations

Available as skid-mounted or containerised units, our energy-efficient ultrafiltration (membrane filtration) systems are available for groundwater, surface water and industrial applications including drinking water, reverse osmosis pre-treatmentirrigation waterblowdown reuse in cooling towers, boiler feedwater treatment and other industrial process water.
 
Australian made with high quality components our ultrafiltration (membrane filtration) plants arrive at your facility fully factory-tested and ready to be energised. This way installation, commissioning and start-up times are minimal.
