Patent number: 8440082Abstract: Method for the liquid solid separation of material mixtures and suspensions in which the material mixture under pressure is fed into a closed chamber having at least one filter surface and a hydrostatic pressure is generated within said chamber for separating the liquid phase. After separating the liquid phase the chamber is opened and the filter surface together with the filter cake is removed from said chamber. The material mixture firstly is treated by the means of hydrostatic pressure of about up to 0.2 bar, wherein 80 to 90% of the fed volume is removed as filtrate. Thereafter the concentrated remaining volume is drawn off and is further treated in the closed chamber with a pressure of up to 5 bar. By reducing the volume of the chamber finally with a pressure of up to 50 bar the remaining filtrate is separated.Type: GrantFiled: September 14, 2012Date of Patent: May 14, 2013Inventor: Albert Bahr

Patent number: 8409448Abstract: An immiscible lipophilic or hydrophilic liquid phase separated respectively from a continuous hydrophilic phase or a lipophilic phase liquid. Fibers having hydrophilic and hydrophobic properties are mixed, layered, etc., and formed into a filter. The separation mechanism involves capture of small droplets of the immiscible phase, coalescence of the small droplets into larger droplets as the immiscible liquid flows through the fiber filter, and release of the large immiscible droplets from the filter. With respect to separation of a hydrophilic immiscible fluid such as water in a lipophilic continuous fluid such as oil, the hydrophobic fibers will cause small water droplets to migrate towards the hydrophilic fibers whereby large droplets are formed on hydrophilic surface.Type: GrantFiled: January 7, 2010Date of Patent: April 2, 2013Assignee: The University of AkronInventors: George Chase, Prashant Kulkarni
