From the process comes two fractions; a dried sludge and a reject water.
Many of the substances that reside in the sludge before the process is still there after. Som of the substances nd up uín the reject water, but most of the metals and phosphorus end up in the dried sludge. Calcium, potassium and megnesium is more present in the reject water while lead, cadmium, copper and zink is more present in the sludge. Some nitrogen also ends up in the reject water. This means that the reject water also can be used as a fertilizer.
This means that both of the fractions from the process can be utilized. The final sludge product can also be regulated to get a dry solid content of between 30-95 percent. This opens a lot of ways to dispose the sludge.
