A better way to dredge

In order to replace mechanical dredging, harnessing nature's sustainable practices has become a cost-effective alternative for municipal wastewater districts, such as that of Clearlake, California, as highlighted in this article. The system they are using is chemical-free and targets sludge-digesting bacteria that form biofilms, which in turn create a granular sludge bed reactor (GSBR). Biosolids are delivered to the GSBR, liquefied, and turned into gas, which continuously feeds the granules to increase their productivity. Within three months, sludge levels are cut in half.
