  • Patent number: 11401172
    Abstract: A filtration system can comprise a pressure pump configured to apply a pressure on fluid flowing between a first chamber and a second chamber. The filtration system can also comprise a flow sensor configured to determine at least one parameter associated with fluid flowing across a membrane deposited between the first chamber and a second chamber. The filtration system can comprise a pressure sensor configured to determine pressure readings of the fluid flowing from the first chamber to the second chamber. The filtration system can comprise a filtration management system configured to cause the pressure pump to apply a constant pressure on fluid flowing across the membrane for a first predetermined time based on the pressure reading. The filtration management system can be configured to cause the pressure pump to reverse the fluid flow across the membrane.

  • Publication number: 20140158620
    Abstract: A system for the separation of the components of an oil, water, and solids mixture, the system comprising a mechanical separation module comprising an oily water output and an input adapted to receive an oil, water, and solids mixture; and a membrane separation module comprising an oily water input and a recirculation output. The oily water output of the mechanical separation module is in flow communication with the oily water input of the membrane separation module, and the recirculation output of the membrane separation module is in flow communication with the input of the mechanical separation module.

  • Patent number: 8054091
    Abstract: A novel microfluidic device has been developed to measure stability of thin liquid films of water in oil emulsions using electrochemical perturbation of interfaces. This new device can be utilized in rapid classification of de-emulsifiers used in petroleum industries. Although water/crude oil emulsions have been the primary focus of this research, this measurement platform can be used in other industries such as food, cosmetics and bio-engineering (bilayer lipid membranes) as well as environmental remediation of oil spills. The compact design of the device and replacement of the mechanical measurements such as pressure with electrical signal measurements contributes in substantial size reduction of the experimental platform so that it can be employed for onsite measurements in remote areas.
