However, every lagoon will eventually require dredging to remove nonvolatile solids like grit. The mechanical removal of sludge is expensive and disruptive, so the longer a lagoon can go between dredgings, the better. In […]

Causes and Effects of Wastewater Lagoon Sludge Explained

Wastewater lagoon sludge buildup is a common occurrence for wastewater treatment lagoons worldwide. If left unchecked, sludge can lead to higher effluent levels of BOD, TSS and ammonia (not to mention some terrible lagoon odors). For an extreme example of how lagoon sludge can build up, see our previous blog on Wastewater Lagoon Mixing Alleviates […]
