Separation of suspensions by cake filtration is also another area in which he has experience.



air filtration


aqueous filtration

Ram is currently studying a number of applications of fluid and particle separation operations, including sedimentation, cake filtration, depth filtration (deep bed filtration), and aerosol filtration. Applications in paper making operations is a one focus in his research.


particle-fluid separation

Ram's primary area of research is understanding fluid solid mechanics and fundamentals in the wet-end operation of papermaking. His concentration is in de-watering, drainage, and fine particle retention. His other goals are polymeric retention of drainage aids, their function, evaluation, and performance. Ram possesses a thorough understanding of retention, the action of polymers, and the interactions of retention aids under various conditions.
