Hydrell Systems - This Solution extracts energy from wastewater, allowing the use of the treated water and energy on-site or their sale.

Hydrell technology was invented in 2016. It has developed a wastewater treatment technology that allows the recovery of energy, nutrients, and clean water at a much smaller footprint and price than competing technologies. The technology will also be more robust than current comparable systems. Using the Hydrell technology, users have an incentive to treat their wastewater by saving 30%+ of their total operating costs. In its simplest form, the electrolysis of wastewater is catalysed by electroactive microorganisms oxidising organic and inorganic compounds on the anode (the positive electrode). The reaction products are car­bon dioxide (CO2) and nitrogen gas (N2). At the same time, hydrogen gas (H2) is formed on the cathode and converted to methane by methanogenic microbes.
