Features & Information

Designed to deliver higher permeate flow rates in lower pressure applications, the ERO is SPECTRUM’s high production, low pressure membrane and can deliver outstanding performance at pressures as low as 6.9 bar.


How does the anti-fouling media extend the membrane's life?

The anti-fouling media helps prevent the accumulation of contaminants and fouling on the membrane surface. This reduces the frequency of membrane cleaning and replacement, thereby extending its overall lifespan.

How does the fibreglass outer finish improve the ERO?

The fibreglass outer finish provides durability and protection, ensuring that the system remains secure and less susceptible to external factors, such as physical damage or environmental exposure.

What types of contaminants can an RO membrane remove from water?

RO membranes are highly effective in eliminating dissolved solids as well as the following contaminants:

  • Calcium
  • Magnesium
  • Heavy Metals
  • Bacteria
  • Viruses
  • Pesticides
  • Organic Compounds
How does an RO membrane work to purify water?

An RO membrane uses a semi-permeable barrier to allow water molecules to pass through while blocking the passage of dissolved solids and contaminants. This selective permeation process effectively removes impurities from the water.
