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.

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.

Control Cabinet
Medium-pressure ultraviolet disinfection equipment is a high-tech product developed by Purevita based on many years of disinfection experience and combined with a number of large and medium-sized municipal water disinfection and swimming pool water disinfection experiences, jointly developed by professors of various disciplines, design engineers, and on-site operators. The L-shaped appearance structure is more optimized than the conventional cross-shaped structure, and the ultraviolet utilization rate is higher.

The polarity reverse titanium electrolytic cell is utilized in sodium hypochlorite generators. Sodium hypochlorite solution is produced by electrolyzing a sodium chloride solution without a membrane and then diluting it. This technology is suitable for various applications including sodium hypochlorite generators, water treatment equipment, and electrolytic disinfection equipment.

Fenton reaction: Under acidic conditions, H202 reacts with Fe2+to produce hydroxyl radicals, which can rapidly oxidize and decompose recalcitrant organic compounds. Our Magnetic Fenton Package System magnetize water molecules to rearrange them in the direction of magnetic field lines, greatly increasing the efficiency of hydroxyl radical oxidation and decomposition of COD. This can decompose most difficult to degrade organic compounds into carbon dioxide, water, and simple organic compounds
