Abstract

Disclosed herein are embodiments of a system for treating water. The system comprises a biochar inlet, and optionally a metal salt inlet, ozone inlet, organic carbon compound inlet or any combination thereof. The biochar may be produced by biomass pyrolysis and the pyrolysis may be coupled to energy generation. The system also comprises a filtration device, such as a reactive filtration device. The system produces a treated water stream and a reject stream, which may be further separated into a recycled water stream and a solid product. The solid product may be suitable as a soil amendment for application to agricultural land, or for recycling. A method for using the system to treat water also is disclosed.
