Our  polyvinylidine fluoride spiral wound microfiltration elements provide microfiltration with a nominal pore size of 0.2 micron, offer high flux at low operating pressures, and are ideal for food,  oil and waste water applications.

AMI  membrane elements are among the finest in the industry. With hundreds of thousands of membranes in operation world-wide, we offer these spiral wound microfiltration PVDF MF membrane elements in standard residential and commercial sizes. our  Microfilter Membranes are Made in the USA  in  ISO 9001:2008 Certified Facilities. Each PVDF MF membrane meets or exceeds our strict performance requirements before shipping.  For the past 30 years we have earned a reputation of delivering consistent, high quality which makes AMI  Microfiltration Membranes the natural choice for use in water treatment systems.

Benefits Microfiltration Membranes

Ultrafiltration, like reverse osmosis, is a cross-flow separation process.  Here liquid stream to be treated (feed) flows tangentially along the membrane surface, thereby producing two streams.  The stream of liquid that comes through the membrane is called permeate.  The type and amount of species left in the permeate will depend on the characteristics of the membrane, the operating conditions, and the quality of feed.  The other liquid stream is called concentrate and gets progressively concentrated in those species removed by the membrane.  In cross-flow separation, therefore, the membrane itself does not act as a collector of ions, molecules, or colloids but merely as a barrier to these species.

Conventional filters such as media filters or cartridge filters, on the other hand, only remove suspended solids by trapping these in the pores of the filter-media.  These filters therefore act as depositories of suspended solids and have to be cleaned or replaced frequently.  Conventional filters are used upstream from the membrane system to remove relatively large suspended solids and to let the membrane do the job of removing fine particles and dissolved solids.  In ultrafiltration, for many applications, no prefilters are used and ultrafiltration modules concentrate all of the suspended and emulsified materials.

About Microfiltration

Membranes with a pore size of 0.1 – 10 µm perform micro filtration. Microfiltration membranes remove all bacteria. Only part of the viral contamination is caught up in the process, even though viruses are smaller than the pores of a micro filtration membrane. This is because viruses can attach themselves to a  bacterial biofilm.
Micro filtration can be implemented in many different water treatment processes when particles with a diameter greater than 0.1 mm need to be removed from a liquid. Microfiltration membranes have the most open pore sizes of all polymeric membranes. With a pore size range of 0.1 to 10µm, microfiltration membranes are capable of separating large suspended solids such as colloids, particulates, fat, and bacteria, while allowing sugars, proteins, salts, and low molecular weight molecules pass through the membrane. MF membranes feature an asymmetric pore structure, with tighter surface pores to control rejection, and more open macrovoids in the membrane cross section, in order to optimise flux.

Examples of micro filtration applications:

· Cold sterilisation of beverages and pharmaceuticals
· Clearing of fruit juice, wines and beer
· Separation of bacteria from water (biological wastewater treatment)
· Effluent treatment
· Separation of oil/ water emulsions
· Pre-treatment of water for nano filtration or Reverse Osmosis
