How Will Nutrient Separation Technology Help You?

Some separation systems are ineffective when used alone in some types of operations. Sedimentation and mechanical separation systems have low separation efficiencies. Neither system effectively removes finer solids (less than 0.25 mm or 0.01 inch in diameter), which can create a number of odor-producing compounds when carbohydrates, proteins and fats decompose anaerobically. These finer solids also contain nutrients such as nitrogen and phosphorus. Therefore, sedimentation or mechanical separation alone may not significantly reduce odors or nutrients from biological waste and wastewater.

In sand separation, chemicals sometimes need to be added to improve the yield of the sand filter. A disadvantage of sand filtration is the rinse water that is created when the sand filter is never cleaned. This heavily polluted water must be treated and disposed of.

Our CLEARED (Control Loop Enhanced Aerobic Retention Effluent Digester) Lagoon Management System processes the fluidized manure into a nutrient soup. The fluidized suspension is then sent to a medialess separator, our AquaRegia™ technology, that processes the suspension into a nutrient free and a separate nutrient rich stream.

The AquaRegia™ system is low power, autonomous, operator friendly and remotely monitored. While yields vary, it is typical to expect 75% nutrient free and 25% nutrient rich output. The nutrient rich water is now available as a fluid liquidizing agent or mixed digestive for further processing to form dispersible solid fertilizer.

Advantages to Solids Separation Include the Following:


  • Reducing the initial size of the lagoon or storage pond, which lowers construction costs; increasing handling flexibility for ultimate disposal and use of animal waste;
  • Solids separation prior to storage reduces the solids accumulation in holding ponds and lagoons. This increases the time between sludge removal operations and maximizes the liquid storage capacity of the holding pond or lagoon.
  • Reducing the amount of biological waste by solid separation tends to reduce the production of objectionable odors.


Nutrient Separation Technology will take the process to the next level, yielding cleaner water and a better nutrient rich output when used in conjunction with an aerobic or anaerobic digesters or a combination of the two.
