Double Layer CompressionIn the double layer compression mechanism large quantities of a salt that has no charge (neutral) are added. The salt works by compressing the double layer around the colloid. When the outer layer is compressed, the repulsive energy barrier around the colloid is reduced or eliminated. This allows the particles to combine.
|
Exceptional Quality BiosolidsBiosolids that meet stricter pollutant and pathogen reduction criteria.
|
Facultative BacteriaBacteria that can use either dissolved oxygen or chemically derived oxygen (from nitrate, sulfate or carbonate) for respiration and use organic materials for energy and growth. In other words, facultative heterotrophs can live under aerobic, anoxic or anaerobic conditions.
|
FiltrateLiquid derived from the dewatering of sludge.
|
Finished WaterWater that has been treated and is ready to be delivered to customers.
|
FlocMasses of non-settleable microorganisms and particles that come together to form progressively larger, heavier particles. |
Flow RateRate of wastewater flow through a wastewater treatment facility, typically measured in million gallons per day (MGD).
|
