Stakeholders

Dry-tested SWRO

The next-generation Sea Water Reverse Osmosis (SWRO) technology enables customers to transition from wet to dry testing, which increases shelf life and offers more flexibility for storage. In addition, dry SWRO improves sustainability, safety, and ergonomics during operation. The resultanting products will continue to meet or exceed membrane performance standards to achieve long-term operational benefits.

Sustainability Benefits

 

  • Dry SWRO membranes reduce energy consumption
  • Lower carbon dioxide emissions due to lower membrane weight and alternative testing process.

USP

  • Longer storage time
  • Easier inventory and warehouse management
  • No need to check conditions of preservation solution
  • Reliable high quality and extended product warranties
  • Safer installation due to 4kg reduction in weight and ease of handling

How does this work?

  • Reverse osmosis (RO) is a pressure-driven separation process that employs a semipermeable membrane and the principles of crossflow filtration.
  • In this RO treatment, the dry-tested SWRO portfolio is a Spiral-wound element with polyamide thin-film composite membrane.
  • The RO membrane acts as a barrier to all salts and inorganic molecules, as well as organic molecules with a molecular weight greater than approximately 100. This is a highly effective process for removing contaminants such as nitrates, soluble salts, metal ions, pyrogens, pesticides, etc.
  • Dry SWRO elements do not contain the preservation solution, enhacing operational benefits for customers.
