A U.S. Patent for a “Method of Actuation of an Alternating Tangential Flow Diaphragm Pump” was awarded to Repligen on September 15th, 2020. The present invention is a method of controlling a diaphragm pump, comprising: actuating a pumping operation of a fluid from a first container by alternating a supply of a positive air flow and a negative air flow to an air side of a diaphragm pump through an air flow line connected to an output of an air flow regulator; suctioning the fluid from the first container by applying the supply of negative air flow to the air side of the diaphragm pump; directly monitoring, by a plurality of sensors along a permeate fluid pathway. Learn More
