Remove heavy metals, suspended solids and emulsified organics using electricity instead of expensive chemical reagents.
Electrocoagulation is an electro-chemical process that simultaneously removes heavy metals, suspended solids, emulsified organics and many other contaminants from water using electricity instead of expensive chemical reagents. The process uses electricity and sacrificial plates to combine with contaminants in a waste stream, producing insoluble oxides and hydroxides that are easily separated from the clear water.
Treatment levels typically below the capabilities of conventional chemical precipitation — ideal for low-limit permits.
Attractively priced standard and engineered systems that can retrofit existing treatment lines.
Several contaminants treated at once across a wide pH range — no need to segregate waste streams.
In many cases the use of treatment chemicals is eliminated, with pH adjustment often unnecessary.
Metal concentrations in the effluent are lower than chemical processes can attain.
Dramatically less sludge produced — a 40–60% reduction over chemical methods — and better feed for R/O.
Step 1 — Dissolution: a low-voltage current passes through the effluent via sacrificial metal plates, releasing coagulant ions directly into the water. Step 2 — Coagulation: those ions neutralise the charges that keep metals, fine solids and emulsified oils suspended, so they clump into dense flocs that are easily separated.
