The DC power supply at the heart of every electrocoagulation (EC) cell. A thyristor-controlled rectifier delivers stable, current-regulated DC to the sacrificial electrodes, dissolving iron or aluminium in-situ to coagulate emulsified fats, proteins and colloids — with no external coagulant dosing.
Indicative ratings — configured to the duty, flow, and water chemistry of each project.
The control it provides is what makes the surrounding process stable, efficient, and compliant.
Thyristor (SCR) firing-angle control holds the set current regardless of changing electrolyte conductivity, so iron dosing stays proportional to treatment demand rather than to water chemistry.
Programmable polarity reversal evens electrode wear and limits passivation/scaling on the plates, extending electrode life and holding performance between cleans.
Current set-point can be paced from flow or COD load, so Fe²⁺ generation tracks the real organic load — the EC equivalent of flow-paced chemical dosing.
Over-current, over-temperature and earth-leakage protection plus current/voltage telemetry to SCADA make the rectifier a controllable, alarmed asset, not a black box.
Smooth 0–100% current turndown lets one unit serve variable flow and load without over-dosing iron at low demand.
4–20 mA / fieldbus set-point and feedback for full remote control, trending and alarm handling.
Fan- or water-cooled thyristor stack rated for continuous duty in warm plant rooms.
Phase-controlled design with input filtering keeps harmonics and power factor within site limits.
Configurable reversal interval matched to feed scaling tendency.
Modular SCR stack and isolation for safe electrode and rectifier maintenance.
