The water then defines air volume which passes through the material which has been treated. Difference between Maceration and Percolation. Maceration is a process which is done in order to provide certain liquid or chemical to any substance.The key target of the process of maceration is to make the substance, on which liquid is applied, softer than before.Percolation, on the other hand, is the method of filtration in which soil or any other substance is passed through some substance to take some pollutant or color out of that substance.Percolation makes use of gravity and biological techniques which are allowed to make some substance free of pollution.he key target of the process of maceration is to make the substance, on which liquid is applied, softer than before.
