The treatment process in progress, using chemicals naturally abundant in wastewater to clean itself
The wastewater sludge that remains after treated water is removed from a hydrotalcite treatment
Using wastewater to clean itself is the premise of new Australian technology that relies on the formation of compounds called hydrotalicites, and which results in less sludge than traditional water treatment with lime. In one test in Australia, the equivalent of 20 Olympic-sized swimming pools of wastewater were treated, with final sludge reductions of up to 90 percent.
