MEMBRANE FILTRATION SYSTEMS

MEMBRANE FILTRATION SYSTEMS

The presence of physical contaminants in raw water or process water streams can present challenges to the use or subsequent treatment of the process stream.

An effective membrane filtration system is able to reduce the presence of physical contaminants, including suspended solids, resulting in a cleaner supply of water.

GROUP STRUCTURE

In order to satisfy the increasing water quality requirements for potable water, industrial and other specialist water requirements, the removal of suspended solids represents an important requirement. In recent years, a range of membrane filtration processes have been adopted, in order to address these requirements. Membrane filtration is commonly utilised as part of an efficient solids removal system, in application where solid material is entrained in a process fluid, including raw water. In some instances, the membrane filtration system removes the requirement for more conventional pre-treatment processes, ensuring cost effective filtration as well as water treatment plants with a reduced footprint.

 

Given membrane filtration is a physical separation process, the selection of an appropriate membrane pore size can be selected to remove specific impurities, down to virus sized particles.

 

Typical Membrane Filtration Scale

  • Microfiltration (MF), typical pore size of 0.1 – 1 μm, will remove bacteria, asbestos, paint pigment
  • Ultrafiltration (UF), typical pore size of 0.01 – 0.1 μm, will remove viruses, colloidal silica
  • Nanofiltration (NF), typical pore size of 0.001 – 0.01 μm, will remove synthetic dye, pesticide
  • Reverse Osmosis (RO) is smaller again, capable of removing aqueous salts and metal ions. For more info, visit our Reverse Osmosis & UPW Systems

 

During the filtration process, the solid particles that cannot pass through the filter membrane are described as oversize and the fluid that passes through the membrane is called the filtrate. Oversize particles may form a solid layer on the filter membrane and may also block the filter pores, preventing the fluid phase from crossing the filter membrane – this process is referred to as blinding. The size of the largest particles that can successfully pass through a membrane filter is called the effective pore size of that filter. The filtration process results in a gradual accumulation of entrapped solids on the membrane surface, which require intermittent removal by means of a filter wash cycle and occasionally a more intensive membrane cleaning process. Expertise in the design and operation of an appropriate membrane filtration system will ensure efficient solid-liquid separation, high performance and long life of the membrane filtration system.
