Features

1. The power supply can operate in either voltage-regulated current-limited mode or current-regulated voltage-limited mode, with seamless switching between the two states.
2. DC output voltage regulation accuracy ranges from 50% to 100%. When input voltage fluctuates by 10% or load changes occur, the output voltage remains stable with regulation accuracy ≤0.5%.
3. Incorporates filtering functionality to prevent interference with instruments during power-up, eliminate grid pollution, and mitigate current inrush phenomena.
4. Phase Loss Protection: Automatically locks out when any phase is missing from the three-phase AC input. Resumes operation automatically after fault resolution.
5. Overcurrent Protection: Automatically enters overcurrent shutdown and alarm state when current exceeds rated value.
6. Short-circuit protection: In case of load short-circuit or internal component short-circuit, the circuit breaker automatically disconnects the power supply.
7. Over-temperature protection: When abnormal temperatures of semiconductor components (e.g., IGBT, Schottky diodes) reach ≥80°C, the electronic switch on the main control board activates, locking the power supply to effectively protect the unit.

How Single Pulse Technology Enhances Electrocoagulation Efficiency

To understand this advancement, we must first examine traditional limitations. Continuous DC often leads to rapid electrode passivation. A non-conductive oxide layer forms on the anode surface. This barrier drastically reduces ion release over time.

Single pulse technology directly addresses this core issue. It applies current in precise, intermittent bursts. Between each pulse, the circuit briefly opens. This allows chemical reactions at the electrode interface to partially reverse. Consequently, the passivating layer cannot stabilize effectively.

The result is sustained high efficiency. The anode material releases coagulant ions more consistently. Furthermore, the high-voltage pulse (up to 500V) enhances electrophoretic movement. Charged pollutants migrate faster toward the electrodes. This dual action—maintained electrode activity and forced particle movement—ensures optimal treatment from start to finish.

Applications in Challenging Wastewater Treatment Scenarios

Certain industrial effluents are notoriously difficult to treat. Oily wastewater, for instance, contains stable emulsified hydrocarbons. Traditional methods struggle to break these down. Similarly, heavy metal complexes and persistent dyes pose significant challenges.

Here, single pulse technology demonstrates its unique value. The high-voltage pulses (500V capability) electroporate microbial cells. This action disrupts biological sludge bulking. More importantly, the intense field destabilizes tough oil-water emulsions. It forces droplets to coalesce for easier removal.

The applications extend to specific critical industries. In metal finishing, it tackles complexed nickel and chromium. For textile plants, it decolorizes stubborn dyes efficiently. Landfill leachate, with its high organic load, is another ideal candidate. In each case, the pulsed energy overcomes the wastewater's inherent resistance to treatment.

Advantages Over Continuous DC Electrocoagulation Systems

Choosing a technology requires a clear comparison of benefits. Continuous DC systems have higher long-term operational costs. They consume more energy for the same treatment effect. Electrode consumption is also significantly faster due to passivation.

In contrast, the single pulse system offers measurable savings. Energy consumption can be reduced by up to 40%. This is due to the off-time between pulses. Electrode lifespan is extended by 60-100% for the same reason. The periodic current interruption minimizes oxide layer formation.

Operational and performance advantages are equally compelling. The system produces denser, more settleable flocs. Sludge volume is consequently reduced by approximately 30%. Process control is also superior. Operators can adjust pulse parameters for varying influent quality. This flexibility ensures consistent effluent standards are always met, providing a clear return on investment.
