Bio Engineering company N-Viro:

The N-Viro process can receive biosolids as low as 12% solids, however, the higher the solids the better. Dependent upon facility design biosolids can be received directly from dewatering into the processor, tipped onto a receiving floor, or delivered into a receiving bin. A key aspect regarding receiving is the process allows for a wide spot in the line which allows operators to run the equipment automatically which enables more time to focus on the efficiencies of dewatering Other Domestic Operations includes sales of territory or site licenses and royalty fees to use N-Viro technology in the United States. http://www.nviro.com

Foreign Operations includes sale of territory or site licenses and royalty fees to use N-Viro technology in foreign operations. Research and Development, the Group contracts with Federal and State agencies to perform or assist in research and development on the Group's technology
The single most critical cost component to every beneficial use option is the ability to get as much water out of the biosolids as possible in the dewatering process. An investment into state-of-the-art dewatering equipment is always worth the analysis. Management Operations provides employee and management services to operate the Toledo Ohio Wastewater Treatment Facility and the Daytona/Volusia County Florida Treatment Facility
