Extended Fin Electrochemical System (EFECS) for Point-of-Use Greywater¶
Rainwater & Storage • Est. CapEx: $275 USD • Lifespan: 7–15 Years
Technical Overview¶
A compact, point-of-use electrocoagulation unit featuring finned electrodes engineered to treat domestic laundry greywater for non-potable reuse. The system is designed for decentralized, small-scale urban settings where water can be recycled at the source rather than sent to central plants.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | Rainwater & Storage |
| Capital Cost (CapEx) | $275 USD |
| Power / Energy | Electric / Motorized |
| Target Scale | Community Scale |
| Standard Lifespan | 7–15 Years |
| Technology Maturity | Prototype |
| Primary Mechanism | Finned electrode geometry increases active surface area and disrupts mass-transport limitations, accelerating the electrochemical release of metal ions under applied DC voltage. These ions generate hydroxide flocs in situ that adsorb surfactants (LAS), organic matter (COD), and turbidity from laundry wastewater. |
