What adjustments should be made to a firm, dry cake in relation to sludge dewatering?

When a firm, dry cake is produced through sludge dewatering, the process typically indicates that the moisture content has been sufficiently reduced. Since the cake is already firm and dry, it is generally stable and ready for handling or disposal without the need for further modifications. The conditions achieved in the dewatering process suggest that the cake's physical properties are suitable for its next steps, such as landfill disposal, land application, or incineration.

In this context, significant adjustments may not be required because the dryness of the cake indicates effective moisture removal, which is the primary goal of sludge dewatering. The moisture levels have already been optimized during the dewatering process, indicating that the equipment and methods used were sufficient. While filtration enhancements can always be considered depending on the specific operational goals, they are often unnecessary once the desired dewatering has been achieved. As a result, the characteristics of a firm, dry cake signify that it has reached an optimal state post-dewatering, negating the need for additional adjustments.
