Low Pressure Open Channel UV System for waste water plant

Purevita UV Sterilization Technology utilizes a specially designed high-intensity, high-efficiency, and long-life C-band 253.6nm ultraviolet light generator to produce powerful UV irradiation for water streams. This UV light destroys the DNA structure of pathogens in water, rendering them inactive and achieving sterilization. The principle of UV sterilization relies on photon energy: shorter wavelengths correspond to higher photon energy, resulting in stronger germicidal efficacy. At 253.6nm, UV light rapidly and efficiently disrupts bacterial DNA, preventing replication and ensuring effective water disinfection.

 Low Pressure Open Channel UV System for waste water plant

Brief Introduction

The sewage treated by the Low Pressure Open Channel UV System for waste water plant passes through the UV system module arranged in the slotted ditch to sterilize and disinfect the water flowing through the ditch, thereby solving the problem of excessive bacteria indicators in the treated sewage. The open channel ultraviolet disinfection system has a fast sterilization speed, good effect, high sterilization efficiency, low operating cost , and no secondary pollution caused by disinfection .

 

Optimized for hydraulic performance, this design ensures uniform flow, minimal head loss, and consistent UV dose distribution, guaranteeing high disinfection efficiency under varying conditions. Modular scalability makes it ideal for new installations or retrofits.

 


Our Proprietary Technologies


1. Parallel Central Drive Cleaning Technology
Eliminates quartz sleeve cracking caused by unilateral force in traditional single-drive systems.
2. Adaptive Flexible Cleaning Ring Technology
Resolves sleeve jamming due to temperature variations. A dual-thickness cleaning ring design eliminates dead zones and ensures thorough cleaning. Double-layer rings enhance quartz sleeve maintenance.
3. Passive Flow-Controlled Flap Gate Technology
Automatically adjusts channel water levels based on flow rate. An electric closed-loop control system maintains optimal disinfection channel height for consistent efficacy.


 

 

Specification of UV System

  • # Light Source: Low-Pressure Mercury Amalgam Lamps
     
    Compared to standard germicidal lamps, mercury amalgam lamps (LIGHT SOURCE) deliver 3x higher UV output at the same length and maintain stable intensity across a broad temperature range (4–40°C). Enhanced UV output reduces the number of lamps required without compromising performance. With a lifespan of 16,000 hours, these lamps significantly lower the initial and long-term maintenance costs.
  • # Quartz Sleeves
    Made from ultra-high-purity quartz, sleeves provide exceptional UV transmission and infinite lifespan if kept free of scratches or fouling. Contamination blocks UV light, reducing disinfection efficiency. Our patented technologies ensure optimal sleeve cleanliness and minimize breakage risks.
  • # Control Cabinet
    Designed for industrial environments, the cabinet embodies “fully automated operation” . With multiple functions and design options, they can be custom-designed for diverse applications and climatic conditions. All internal components are sourced from renowned brand suppliers to ensure smooth and energy-efficient operation. The control system include overload, short-circuit, overvoltage, and motor phase-loss protection. It also includes self-diagnostics, fault alarms, real-time UV dose adjustment, and remote monitoring via PLC/SCADA integration.
