Features & Information

SPECTRUM’s specially formulated ‘Window Wash’ membrane for the glass cleaning industry. With rejection rates of 98.5%, the WW range is comparable with industry-established pure water production membranes, whilst still competing in price with imported alternatives.


What are the WW-4040 and WW-4021 RO membranes and what sets them apart?

The WW-4040 and WW-4021 RO membranes are specifically designed economic low-energy RO membranes. They are known for delivering uncompromised water quality while being a cost-effective choice. These membranes excel in both quality and performance, making them ideal for competitively priced markets; particularly window washing.

What is the maximum daily output of purified water that these membranes can provide on-demand?

The SPECTRUM WW membranes can deliver up to 8,350 litres per day of on-demand purified water, making them suitable for applications with varying water consumption needs.

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.
