Semi-Permeable Membrane Devices

Semi-permeable membrane devices are comprised of a selective membrane oil packet that is jacketed in a stainless steel perforated housing. The SPMD can then be deployed on anchor or buoy for a period of time in a water body. SPMDs can also be deployed and retrieved discretely by use of an anchor, a float or an acoustic release. The anchor is attached to the acoustic release to which the SPMD is tethered and then a float is added to provide enough positive buoyancy to keep the SPMD in a vertical position. The entire assembly remains below the water surface.
