PWN Technologies demonstrates the effectiveness of ceramic membranes

PWN Technologies, in partnership with WABAG and METAWATER, will demonstrate the effectiveness of ceramic membranes as a pre-treatment for Sea Water Reverse Osmosis in a trial held at PUB’s R&D facilty in Tuas, Singapore for a period of 4 months.

The trial will involve a pilot plant with a capacity of 200 m3/d utilising just a single ceramic membrane of 25m2 filtration area.

The robustness of ceramic membranes for seawater desalination has its advantages in that they do not require extensive upstream pre-treatment, resulting in a more compact and operationally reliable plant. This has been demonstrated in the Middle East, and further pilot testing in Singapore would demonstrate the effectiveness of this technology for the region.

This trial is conducted in collaboration with PUB on all technical aspects.

Other objectives of the trial are:

  1. To produce enough data to determine initial optimal flux for stable conditions, and show stable and reliable operation, with minimal down-time and consistent treated water quality;
  2. To determine the filtered water quality (e.g. SID, turbidity, metals, organics) and its suitability for downstream RO treatment.
