Filter Aid

Filter aids are applied in two ways. As shown in Figure 11.4, filter aid can be used as a precoat on the filter medium to prevent blockage or ''blinding'' of the filter by solids that would otherwise wedge themselves into the pores of the cloth. Filter aid can also be added to the fermentation broth, typically at concentrations of 1 to 5% w/w, to increase the porosity of the cake as it forms.
