Stop fouling and speed up your project with on location silt density collection and analysis

You need to clearly understand how your system is performing. With GE’s silt density index (SDI) test equipment, and Sepa scale-up process equipment, you can get the information you need.

For accurate SDI readings, GE offers both auto and manual SDI kits. Sepa CF equipment helps run tests, assays, concentrations, processes, or provide R&D data for any membrane. Using this equipment facilitates scale-up studies prior to larger production runs.

Test Equipment Features

  • Auto SDI kit – quick, easy silt density readings that reduce costly and time consuming manual methods. Push-button calibrated equipment monitors membranes and water quality.
  • Manual SDI kit - industry-wide usage to indicate the quantity of particulate matter in water. It is used with well water, filtered water or clarified effluent samples.
  • Sepa CF II medium/high foulant system - high pressure Cell (up to 1000 psi) utilizes crossflow filtration allowing the customer to put any membrane into the unit. System designed for quick and easy retrieval or replacement of membrane.
  • Sepa membranes - large selection of reverse osmosis (RO), ultrafiltration (UF), nanofiltration (NF) and microfiltration (MF) membranes.

Onsite SDI testing identifies cause of RO membrane fouling

A chemical plant needed to determine why their RO could not run for more than five consecutive days without requiring extensive chemical cleaning.
