One of the treatment plants in this small Nevada desert city faced a particularly challenging issue: their aerobic digestion tanks are aerated with coarse bubble aeration. While coarse bubble aeration is good for mixing, it is inefficient at transferring oxygen. During the hot summer months when the digester tanks get very warm, they battle depressed dissolved oxygen (DO) levels that struggle to get above 0.5 ppm.
The Nevada installation demonstrates that Moleaer XTB nanobubble generators are highly effective supplemental aeration systems that can be retrofitted into a wide range of plants needing cost-effective improvements to existing aeration systems. Most importantly, installation is very simple - a single unit can be installed in less than two hours without disrupting the plant's operation.
