The Esser test as a tool above and beyond beer filtration
Tool for process water treatment | In 1972, Karl Diether Esser presented his membrane filter test for evaluating filterability of beer [1]. At that time, it was important to identify beer with poor filtration properties as simply and early as possible. The question arises today whether the Esser test could also be used nowadays as a valuable tool for applications above and beyond beer filtration.
