Municipal Wastewater


Municipal Wastewater

While there are several robust, reliable and affordable solutions for the removal of nutrients, such as ammonia and phosphorus, from wastewater streams at large centralized treatment plants, most of the traditional biological or physical/chemical options are either impractical or unaffordable for small, decentralized operations.

Building on the well-understood principle of electrolysis, the patented The ECOTHOR® electrotechnology platform from E2metrix combines a high-efficiency, proprietary power management system with a unique, patented alloy electrode to create a modular, process platform that can be easily incorporated into any greenfield or retrofit application to reduce ammonia and phosphorus in the wastewater stream to the strictest discharge quality levels, all the while simultaneously disinfecting the effluent from dangerous pathogens (bacteria, viruses, etc.). While other technologies offer exceptional performance on medium to large wastewater flows, this powerful new platform from E2metrix opens this option to applications in the many thousands of decentralized and small municipal or sanitary wastewater treatment facilities.

ECOTHOR® can contribute to small, decentralized sanitary wastewater operations in numerous ways:

  • ECOTHOR®-EC can remove both ammonia nitrogen and phosphorus from the effluent using its proprietary magnesium-based anodes to produce struvite and prevent the formation of blue-green algae in our waterways;
  • ECOTHOR®-EC can polish municipal wastewater to ultra-low quantities of phosphorus – < 0.03 mg/L;
  • ECOTHOR®-EOx can provide onsite PFAS destruction capabilities.

The E2metrix advantages

  • Multiple contaminants removed simultaneously (high efficiency)
  • Competitive CAPEX, low cost of ownership
  • Service contract available
  • Fully automated with remote operation on multiple platforms
  • Simple-to-operate and easy-to-maintain
  • On/Off Capabilities vs biological processes
  • Compact & modular – small footprint – containers available
  • Complete treatment train available – containerized as well
  • No moving parts.
