Rising costs of managing sewage biosolids (sludge) together with the emergence of new compounds is raising concerns.   Disposal methods such as application onto farmland or landfilling are running into increased regulatory restrictions along with public concerns regarding what is contained in the biosolids (sludge).


Many lagoon systems are more than thirty years old and are hard pressed to accommodate growth and to meet the emerging stringent discharge limitations.


Excessive buildup of sludge intensifies odors and increases the effluent concentrations of BOD, TSS, nutrients, ammonia and pathogens.


Blue Frog System Technology eliminates dredging in a wastewater treatment lagoon, or a sludge holding pond through a process called biodredging.  Biodredging utilizes a collection of natural processes by which microorganisms break down biodegradable material.  Nature optimizes the process by creating a structured environment called a biofilm, wherein the waste from one group is handed off as food to the next group in the food chain.


Blue Frog System digests 100% of organic, biodegradable sludge.


Blue Frog can be a stand-alone system or one that works in combination with other technologies to “clean up” the sludge; eliminating costs and processes associated with mechanically dredging or land applying sludge.
