WHAT EXACTLY IS IT?

PAN-P is derived by biological organisms at local Wastewater Treatment Plants (WWTP).  PAN-P is a brand name given to thesolids portion of the WWTP process after they have been heat dried.  Unlike other organic fertilizer, PAN-P can come in many different forms and nutrient concentrations.  Depending on the WWTP processing type (Aerobic or Anaerobic) PAN-P can vary in nutrient content and nutrient availability.  But the concept and the origin of the nutrients is all the same.  

HOW IS IT MADE?

A municipality typically has a collection system throughout their town in which homes and business discharge their wastewater.  This wastewater works its way through a series of pipes and pumps until it reaches the WWTP.  There the wastewater goes through a series of screening, primary treatment, and settling processes (removal of inert material).  After the wastewater has been refined and homogenized, the microorganisms begin their work.  In most these microorganism work in Aerobic (with oxygen) conditions, but a few WWTPs use Anaerobic (without Oxygen) conditions.  Both treatment processes are very good at stabilizing the wastewater. 

After the treatment process is completed the solids and water portions are separated.  The water goes onto further treatment, sterilization, and is finally discharged into a river or creek.  The solids enter a tank as a liquid where they are further digested by microorganism until a time when that tank must be emptied.  The liquid goes through a dewatering cycle where the solids are coagulated together to produce a drier "cake" consistency product and the water is recycled back through the WWTP.  

The "cake" is then set through a drier which will reach temperatures of 400 to 1,200 degrees Fahrenheit depending on the drier technology used.  Once the product is dried, it is stored on a pad or in a silo where is rigorously tested to meet all state and federal requirements before it is introduced into general public and environment.
