Shelton Associates has an in-house analytical lab (with a dedicated lab service manager) to support customers and field representatives. We can quickly and efficiently perform extensive analytical water testing. In addition to a state-of-the-art inductively coupled plasma mass spectrometer (ICP-MS), we can run in-house ion chromatography (IC) alongside a wide range of bench-scale tests.

Further, Shelton Associates can perform bench-scale membrane tests and membrane autopsies (complete with FTIR and SEM results).

Bench-Scale Applications Lab

In addition to our analytical testing equipment, we have an in-house applications lab, enabling us to test all types of membranes using small volumes of test solution. We can test MF, UF, NF and RO membranes in flat-sheet, spiral, hollow-fiber and tubular configurations. We can also test various pretreatment chemistries. Our qualitative applications lab complements our quantitative analytical lab.

Our Bench-Scale Equipment Includes:

  • 1812 Spiral Test Apparatus (high pressure and low pressure)
  • Flat Cell Test Units (high pressure and low pressure)
  • Hollow Fiber MF/UF Test Units
  • Tubular Polymeric & Ceramic MF/UF/NF Test Units
  • Polymeric Membrane Distillation Units

Membrane Troubleshooting

In addition to supplying capital equipment and servicing existing systems, we also provide the following services:

  • Offsite membrane cleaning (2.5” – 8” diameter spiral elements) at our facilities
  • Membrane cleaning studies
  • Destructive membrane autopsies
  • Accelerated lifecycle testing of new membranes
  • Benchtop and field testing of membranes in new applications or changing operating conditions
