]]> Overview of Water Treatment Rectifier

Water treatment refers to the process of removing unwanted substances from water for industrial and domestic purposes via physical and chemical methods. General-purpose water treatment power supplies are dedicated devices that generate the electric field required for chemical water treatment processes, and water treatment rectifiers serve as the core power equipment in this sector. For example, a 2500A 25V rectifier for wastewater treatment is a typical high‑power unit used in large‑scale chlorination systems, delivering the precise DC output required for effective disinfection.

Among various water treatment technologies, water treatment rectifiers act as critical equipment with irreplaceable functions. By adjusting current characteristics, they deliver stable and reliable power supply for water treatment procedures, thus boosting overall processing efficiency.

What a water treatment rectifier essentially does is take alternating current (AC) and turn it into direct current (DC). The AC coming in gets rectified and filtered, producing a higher DC voltage. That DC then goes through a frequency conversion stage that turns it into high-frequency AC at about 15 kHz. This high-frequency AC is passed through a high-frequency transformer to the secondary side, where it gets rectified and filtered once more to give you the output voltage you need. A control circuit samples both output voltage and current, then uses closed-loop feedback to generate PWM signals that regulate the power conversion stage, keeping the rectifier’s output steady.

Advantages of Water Treatment Rectifier

High Efficiency & Stable Performance
Based on the operational data of tens of thousands of installed units, products deliver outstanding reliability when installed and operated in compliance with specifications. They maintain stable long-term operation and consistently guarantee effective water treatment results.

Eco-Friendly
Water treatment rectifiers eliminate the need for traditional chemical additives in water treatment, enabling truly natural and environmentally friendly treatment processes.

Multi-Layer Protection
Equipped with comprehensive protection mechanisms including overcurrent, phase loss, overtemperature and other safety functions.

Intelligent Control
All rectifiers support local display and operation on the unit itself, as well as remote monitoring and control via PLC. Each unit is fitted with an RS485 communication module. Operating status (running, forward operation, fault, local/remote mode) can be displayed locally and transmitted to the PLC; remote control is also available via 4–20 mA analog signals.

Features of Water Treatment Rectifier

Adjustable Output
Output regulation range: rated voltage 0–100% continuously adjustable, rated current 0–100% continuously adjustable; voltage and current can be regulated independently.

Remote Control Capability
All rectifiers support local display and operation as well as remote PLC monitoring and control, equipped with RS485 communication modules. Each unit integrates local and remote PLC functions including voltage/current adjustment, output voltage/current display, start/commutation control. Real-time operating status (running, forward operation, fault, local/remote mode) is shown locally and uploaded to the PLC; 4–20 mA analog signals are adopted for remote control.

Soft Start & Soft Stop
Built-in soft start and soft stop functions; soft start and soft stop durations can be set on the on-site cabinet.

Reserved Interlock Terminals
The rectifier features interlock functions with reserved terminals for connection to passive normally open contacts inside the client’s control cabinet. The power supply will suspend startup and output when this signal circuit is disconnected.

 

Wastewater Treament Process

Application Scenarios of Water Treatment Rectifier

Liyuan Haina water treatment rectifiers are widely deployed across the water treatment industry, including industrial and domestic sewage treatment, electrolytic treatment of electroplating wastewater, precious metal recovery, seawater desalination, sodium hypochlorite electrolysis and other applications.

Electrocoagulation Water Treatment
This technology uses the DC field from the rectifier to dissolve the anode, releasing metal ions into the water. Those ions meet up with hydroxide ions and form flocculants—aluminum hydroxide is a good example—which then pull out suspended solids, pigments, and heavy metals. In a typical electrocoagulation system, the rectifier powers the electrodes inside the tank, and the water gets cleaned up through these electrochemical reactions.

Electrolytic Wastewater Treatment
Industrial wastewater contains hazardous pollutants including heavy metal ions and organic compounds. Driven by current from water treatment rectifiers, contaminants undergo redox reactions on electrode surfaces and are broken down. In hardware processing and surface finishing wastewater treatment, rectifiers enable recovery and reuse of valuable metal ions such as copper, gold and silver.

Seawater Desalination
In seawater desalination processes such as electrodialysis and reverse osmosis, water treatment rectifiers provide stable DC power to facilitate seawater desalination.

Ballast Water Treatment
Ship ballast water must be treated to prevent invasive marine species. Rectifiers electrolyze seawater to produce disinfectants like sodium hypochlorite for ballast water sterilization.

Electrodeionization (EDI) Systems
EDI is an advanced deep desalination technology for ultrapure water production. Water treatment rectifiers power EDI systems, removing ionic impurities from water via electrochemical reactions to yield high-purity water.

Sodium Hypochlorite Generation
Rectifiers electrolyze seawater or brine, and the sodium hypochlorite produced this way is then used as a disinfectant across various water treatment applications.

Types of Water Treatment Rectifier

High-Frequency Rectifiers
Efficient, energy-saving, precise, and reliable—these rectifiers have found their way into wastewater treatment, seawater desalination, ballast water treatment, and sodium hypochlorite production from seawater or brine. They handle conventional electrochemical processes like electrocoagulation, electrolytic oxidation, and electrochemical disinfection just fine, with output voltages typically landing in the 10–100 V range.

Silicon Controlled Rectifier (SCR) Rectifiers
These are what you turn to when the job calls for higher voltages—high-voltage electrochlorination, for instance.

EDI Power Rectifiers
Custom-developed for Electrodeionization (EDI) systems, capable of precise regulation of output voltage and current with a typical DC voltage range of 50–300 V. These rectifiers deliver stable DC electric fields for EDI modules, with core capabilities of accurate voltage control, current density adjustment and polarity switching to ensure efficient and steady EDI operation. They are extensively applied in EDI systems producing drinking water, industrial process water, pharmaceutical-grade water and electronic-grade ultrapure water.

]]> Overview of Water Treatment Rectifier

Water treatment refers to the process of removing unwanted substances from water for industrial and domestic purposes via physical and chemical methods. General-purpose water treatment power supplies are dedicated devices that generate the electric field required for chemical water treatment processes, and water treatment rectifiers serve as the core power equipment in this sector. For example, an SCR rectifier 500A ±100V for water treatment and electrolysis is a typical high-power model used in large-scale chlorination systems, delivering the precise DC output needed for effective disinfection.

Among various water treatment technologies, water treatment rectifiers act as critical equipment with irreplaceable functions. By adjusting current characteristics, they deliver stable and reliable power supply for water treatment procedures, thus boosting overall processing efficiency.

What a water treatment rectifier essentially does is take alternating current (AC) and turn it into direct current (DC). The AC coming in gets rectified and filtered, producing a higher DC voltage. That DC then goes through a frequency conversion stage that turns it into high-frequency AC at about 15 kHz. This high-frequency AC is passed through a high-frequency transformer to the secondary side, where it gets rectified and filtered once more to give you the output voltage you need. A control circuit samples both output voltage and current, then uses closed-loop feedback to generate PWM signals that regulate the power conversion stage, keeping the rectifier’s output steady.

Advantages of Water Treatment Rectifier

High Efficiency & Stable Performance
Based on the operational data of tens of thousands of installed units, products deliver outstanding reliability when installed and operated in compliance with specifications. They maintain stable long-term operation and consistently guarantee effective water treatment results.

Eco-Friendly
Water treatment rectifiers eliminate the need for traditional chemical additives in water treatment, enabling truly natural and environmentally friendly treatment processes.

Multi-Layer Protection
Equipped with comprehensive protection mechanisms including overcurrent, phase loss, overtemperature and other safety functions.

Intelligent Control
All rectifiers support local display and operation on the unit itself, as well as remote monitoring and control via PLC. Each unit is fitted with an RS485 communication module. Operating status (running, forward operation, fault, local/remote mode) can be displayed locally and transmitted to the PLC; remote control is also available via 4–20 mA analog signals.

Features of Water Treatment Rectifier

Adjustable Output
Output regulation range: rated voltage 0–100% continuously adjustable, rated current 0–100% continuously adjustable; voltage and current can be regulated independently.

Remote Control Capability
All rectifiers support local display and operation as well as remote PLC monitoring and control, equipped with RS485 communication modules. Each unit integrates local and remote PLC functions including voltage/current adjustment, output voltage/current display, start/commutation control. Real-time operating status (running, forward operation, fault, local/remote mode) is shown locally and uploaded to the PLC; 4–20 mA analog signals are adopted for remote control.

Soft Start & Soft Stop
Built-in soft start and soft stop functions; soft start and soft stop durations can be set on the on-site cabinet.

Reserved Interlock Terminals
The rectifier features interlock functions with reserved terminals for connection to passive normally open contacts inside the client’s control cabinet. The power supply will suspend startup and output when this signal circuit is disconnected.

 

Wastewater Treament Process

Application Scenarios of Water Treatment Rectifier

Liyuan Haina water treatment rectifiers are widely deployed across the water treatment industry, including industrial and domestic sewage treatment, electrolytic treatment of electroplating wastewater, precious metal recovery, seawater desalination, sodium hypochlorite electrolysis and other applications.

Electrocoagulation Water Treatment
This technology uses the DC field from the rectifier to dissolve the anode, releasing metal ions into the water. Those ions meet up with hydroxide ions and form flocculants—aluminum hydroxide is a good example—which then pull out suspended solids, pigments, and heavy metals. In a typical electrocoagulation system, the rectifier powers the electrodes inside the tank, and the water gets cleaned up through these electrochemical reactions.

Electrolytic Wastewater Treatment
Industrial wastewater contains hazardous pollutants including heavy metal ions and organic compounds. Driven by current from water treatment rectifiers, contaminants undergo redox reactions on electrode surfaces and are broken down. In hardware processing and surface finishing wastewater treatment, rectifiers enable recovery and reuse of valuable metal ions such as copper, gold and silver.

Seawater Desalination
In seawater desalination processes such as electrodialysis and reverse osmosis, water treatment rectifiers provide stable DC power to facilitate seawater desalination.

Ballast Water Treatment
Ship ballast water must be treated to prevent invasive marine species. Rectifiers electrolyze seawater to produce disinfectants like sodium hypochlorite for ballast water sterilization.

Electrodeionization (EDI) Systems
EDI is an advanced deep desalination technology for ultrapure water production. Water treatment rectifiers power EDI systems, removing ionic impurities from water via electrochemical reactions to yield high-purity water.

Sodium Hypochlorite Generation
Rectifiers electrolyze seawater or brine, and the sodium hypochlorite produced this way is then used as a disinfectant across various water treatment applications.

Silicon Controlled Rectifier (SCR) Rectifiers
These are what you turn to when the job calls for higher voltages—high-voltage electrochlorination, for instance.

EDI Power Rectifiers
Custom-developed for Electrodeionization (EDI) systems, capable of precise regulation of output voltage and current with a typical DC voltage range of 50–300 V. These rectifiers deliver stable DC electric fields for EDI modules, with core capabilities of accurate voltage control, current density adjustment and polarity switching to ensure efficient and steady EDI operation. They are extensively applied in EDI systems producing drinking water, industrial process water, pharmaceutical-grade water and electronic-grade ultrapure water.
