In the agricultural sector, advances in recent years can be related to the evolution of equipment, seeds and agrochemicals. In the production process of liquid agrochemicals, there may be particulates that are not of interest and thus, need to be removed. Removal of solid particles from a liquid medium is by filtration. The bag or bag filter has a simple, low cost and easy access for cleaning. In order to evaluate the efficiency of a filtration system, determination of the medium resistance, determination of the specific strength of the cake and the efficiency and characteristics of the pump used for liquid transfer are important calculations. In a productive process of liquid herbicides, a study was carried out to calculate the efficiency of the filter system (bag type). By calculating the area of the filter element (0.460 m²), the density of the cake (0.99 g. ), the concentration of solids in the suspension (0.00760 kg. ), the cake mass per unit area (0.661 kg. ), average cake thickness (0.09 cm), cake porosity (27%), specific cake strength (5.664 ) and medium strength (94160993 ¹), the viability of the filtration system in the removal of particulates from herbicides was verified.
