Wastewater treatment consumes up to 3 per cent of all electrical energy of urban communities. The industry standard to date has relied on large-scale centralized treatment systems that require significant energy and expense to move and process wastewater. Next generation, decentralized treatment solutions offer the potential to drastically reduce the energetic footprint of wastewater treatment and service rapidly developing, urban and remote population clusters.
To address this issue, Island Water Technologies Inc. has developed the REGENTM Renewably Powered Wastewater Treatment System. This modular treatment technology leverages advances in Fixed Film and bio-sensors with a renewable power management system to provide stand-alone, self-powered wastewater treatment. By combining this low-energy, high efficiency technology with a power management system integrating renewable power and energy storage we can provide stand-alone treatment capability.
The system holds certain unique characteristics over conventional technology that includes:
- Self-powered operation
- Very low energetic footprint (0.38-0.76 kWh / m3 wastewater treated)
- Rapid start-up, easily deployable
- Bio-sensors allowing for remote control and automation
Modular, solar powered wastewater treatment can be an enabling technology that allows for cost effective on-site processing of wastewater for both rural and rapidly developing urban communities.
This self-powered, decentralized approach is focused on delivering
- key CapEx savings by eliminating costing piping and pumping associated with centralized wastewater treatment
- key OpEx savings by operating / powering the installed infrastructure by using solar (photo voltaic) arrays.
- Key infrastructure resiliency where the wastewater infrastructure can be powered independent of grid electrical connection.
This technology is primed for application in remote rural communities and more importantly in rapidly growing urban centers where decentralized, on-site processing of wastewater can be implemented.
