NATHANIEL OSBORNE

Water & Wastewater Treatment Sales Specialist

Nathaniel Osborne received his bachelor’s degree from the University of Toledo in 2015, and then served as an Army Officer in the 10th Mountain Division from 2016-2019. He held roles as an Infantry and Mortar Platoon Leader, and Company Executive Officer, with one tour to Afghanistan. His experience led him to NRM where he took a role of Sales Specialist for Water and Wastewater treatment technologies. He has been with NRM since September of 2022, and works with industrial, commercial, agricultural, municipal, and residential water and wastewater treatment systems. His scope of work is focused on decreasing or eliminating sources of pollution in our watershed, such as failing sewage treatment systems, agricultural run-off, and industrial/municipal wastewater. He is achieving this with the introduction of sophisticated biology (SludgeHammer and BioPro), aeration/oxygen delivery (PRO2), and our ability to capture excess nutrients at their source via Timberchar (biochar).

The development of wastewater solutions allowed NRM to establish SludgeHammer NW Ohio to provide additional technology to the residential and commercial wastewater industry. The SludgeHammer has been certified by IAPMO under their IGC180-2003, by Marpol under their IMO RES.MEPC.159(55) standard, and by National Sanitation Federation NSF 40 Standard. The SludgeHammer has been widely used for remediation of existing domestic on-site systems and as an advanced treatment system in individual households, community systems, commercial and high-strength load systems, as well as mobile worker-housing facilities for remote worksites without sewer services.
