Membrane Filtration Coating

Fouling of filtration membranes adds considerable cost to the treatment of wastewater and the production of potable water.

A BIOINVISIBLE coating on industrial filters can:

  • Prevent build up of organic materials
  • Maintain higher flux for longer
  • Improve membrane cleaning efficiency
  • Extend usage and reduces costs
  • Safe & Non-Toxic
  • Ultra-thin coating <10nm
  • Environmentally Sustainable
  • Scalable Coating Process

Water Treatment

Research conducted by expert biomaterial scientists and biologists indicates that industrial membrane filters coated with TekCyte’s patented coating technology, BIOINVISIBLE, will dramatically reduce fouling.

  • Drinking water
  • Industrial water supply
  • Irrigation water
  • River flow maintenance

Liquid Filtration

BIOINVISIBLE coating improves the performance of industrial membranes leading to higher throughput and lower maintenance costs.

  • Alcoholic beverage filtration e.g. beer and wine
  • Non-alcoholic beverage filtration e.g. production of fruit drinks, milk

Proof it works

Long term filtration experiments conducted by the University of Queensland that monitored the fouling and the ease of removal of foulants revealed superior antifouling on PVDF, PP and PTFE membranes. In addition to the significant lower fouling rate the coated membranes also required significantly less or no further cleaning.

Graph Recreation
  • Pristine membrane (benchmark)
  • Coated membrane
  • The onset of fouling is significantly delayed
  • Extend of fouling is significantly reduced
  • Membranes are more thoroughly cleaned and regenerated
Better performance.
Lower maintenance costs.
