Water treatment plants rely on pumps and blowers to move water, sewage, and chemicals. Unstable motor control causes overflow or insufficient flow—issues solved by SHUYI Water Treatment Frequency Converter, tailored for the unique demands of water-related processes.

1. Precise Flow Control for Water Treatment Processes

Different water treatment stages need varying flow rates. Sewage sedimentation requires slow, steady pump speeds, while disinfection needs consistent chemical delivery.

SHUYI Water Treatment Frequency Converter adjusts motor speed in 0.1Hz increments. This precision ensures sedimentation tanks don’t overflow and filtration systems get just the right water volume.

For example, in a municipal water plant, it slows pumps during off-peak hours when water demand drops, avoiding energy waste while maintaining water quality standards.

2. Corrosion Resistance for Humid, Chemical Environments

Water treatment sites are harsh: humid air, chlorine, and sewage chemicals easily damage electrical equipment. Traditional converters often fail within 1-2 years here.

SHUYI’s converter uses a special anti-corrosion coating on internal circuits and an IP65-rated enclosure. It blocks moisture and chemical fumes from seeping into key components.

In coastal water plants with salt-laden air or industrial wastewater facilities, this design extends the converter’s service life to 5+ years, reducing replacement costs.

3. Energy Savings for Water Plant Operations

Pumps and blowers account for 60% of a water treatment plant’s electricity use. Fixed-speed motors run at full power even when low flow is enough, wasting energy.

SHUYI Water Treatment Frequency Converter matches motor speed to actual demand. A sewage treatment plant in Guangzhou reported 38% lower energy bills after upgrading to this converter.

It also reduces startup current by 70% compared to direct-on-line starting. This prevents voltage spikes that disrupt other plant equipment like sensors and monitoring systems.

4. Compatibility with Water Treatment Equipment

Water plants use diverse machinery: centrifugal pumps for raw water, submersible pumps for sewage, and roots blowers for aeration tanks. Finding a universal converter is challenging.

SHUYI’s converter supports 0.75kW to 315kW motors, covering most water treatment equipment. It works with both new and old motors, no need to replace existing machinery.

For aeration blowers, it has a built-in pressure control mode. It adjusts speed based on oxygen levels in the tank, ensuring efficient biological treatment of sewage.

5. Compliance with Global Water Industry Standards

Water treatment equipment must meet strict international standards to ensure safe, reliable operation. Non-compliant products risk project delays or rejection.

SHUYI Water Treatment Frequency Converter holds CE, UL, and ISO 9001 certifications. It meets EU’s ErP energy efficiency directives and China’s GB/T 12668 standard.

It also has a fault self-diagnosis function that records error codes. This helps technicians quickly resolve issues, minimizing downtime—critical for plants that operate 24/7.
