Oscillatory Electrocoagulation for Surface Water and Greywater¶
Rainwater & Storage • Est. CapEx: $1,400 USD • Lifespan: 7–15 Years
Technical Overview¶
An emerging electrocoagulation variant that applies oscillatory electrical or hydraulic conditions to treat surface water and greywater in decentralized, compact settings. It aims to reduce electrode fouling and improve coagulation kinetics compared to static DC systems.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | Rainwater & Storage |
| Capital Cost (CapEx) | $1,400 USD |
| Power / Energy | Electric / Motorized |
| Target Scale | Community Scale |
| Standard Lifespan | 7–15 Years |
| Technology Maturity | R&D |
| Primary Mechanism | Oscillatory current or pulsed flow disrupts boundary layers at the electrode surface, mitigating passivation and enhancing collision rates between flocs and colloidal particles. Sacrificial iron or aluminum anodes release coagulant ions that form hydroxides, aggregating suspended solids and organic contaminants. |
