Water Park Medium Pressure UV Sterilizer

Product Advantages

● Powerful Broad-Spectrum Sterilization: The 3kW medium-pressure lamp releases 200-400nm broad-spectrum ultraviolet light, effectively killing common microorganisms such as E. coli and Legionella, as well as destroying the cell walls of drug-resistant bacteria and viral nucleic acids. It achieves a kill rate of ≥99.99% against pathogens that are difficult to inactivate with traditional disinfection methods, such as Cryptosporidium. Simultaneously, it decomposes chloramines and odor-causing substances in the water, improving the taste and clarity.

● Pneumatic Automatic Cleaning: Utilizing a compressed air-driven ring-shaped cleaning mechanism, it can be set to clean at 0-24 hour intervals or automatically start based on lamp contamination levels (detected by a light transmittance sensor). The cleaning process is friction-free, completing the cleaning of a single lamp within 30 seconds, maintaining an ultraviolet transmittance of ≥90%, avoiding downtime and lamp wear caused by manual cleaning.

● PLC Intelligent Control: Equipped with an industrial-grade PLC controller and a 7-inch color touchscreen, it displays key data such as lamp power, running time, UV dose, and cleaning records in real time. It supports graded adjustment of disinfection intensity (e.g., dynamic power adjustment based on flow rate during different time periods), and features self-diagnostic and audible/visual alarm functions for over-temperature, over-pressure, and lamp malfunctions. Operation is intuitive and convenient.

● Remote Communication Control: Supports Modbus RTU, TCP/IP, and other communication protocols, allowing integration with IoT platforms or existing user control systems. Administrators can remotely view equipment status, receive alarm information, and modify operating parameters (such as cleaning cycle and disinfection mode) via mobile app or computer terminal, enabling unattended operation and centralized management of multiple devices. This is particularly suitable for decentralized or large-scale water treatment projects.

● Stable and Durable Design: The lamps use imported quartz glass and high-temperature resistant electrodes, with a lifespan of ≥8000 hours. The main body of the equipment is made of 316 stainless steel, resistant to acid and alkali corrosion (suitable for water bodies with pH 5.5-9.5). The pneumatic system uses food-grade seals to prevent secondary contamination. The overall protection level is IP66, suitable for humid and dusty industrial environments. III. Main Functions

● Medium-Pressure Ultraviolet Sterilization: A 3kW medium-pressure lamp generates high-intensity, broad-spectrum ultraviolet light, achieving rapid sterilization by destroying the DNA structure of microorganisms. Simultaneously, 185nm wavelength ultraviolet light assists in the decomposition of trace organic matter in the water (such as pesticide residues and small industrial molecule pollutants), improving overall water quality indicators.

● Adaptive Pneumatic Cleaning: A transmittance sensor monitors the lamp surface contamination level in real time. When contamination causes the transmittance to drop below 80%, the PLC automatically initiates pneumatic cleaning. The cleaning cycle can also be manually set (e.g., every 4 hours). Compressed air drives the cleaning ring to wipe the lamp surface, removing scale and biological slime without requiring shutdown.

● PLC Intelligent Control: The touchscreen allows setting "Automatic/Manual" modes. In automatic mode, the equipment dynamically adjusts the ultraviolet power according to the inlet water flow (requires an external flow meter) to ensure a stable disinfection dosage (≥30mJ/cm²). Manual mode supports emergency power adjustment to cope with sudden water pollution.

● Remote Centralized Management: Device data is uploaded to the cloud via a 4G/Ethernet module, supporting multi-terminal access (mobile phones, computers). Real-time monitoring of UV intensity, cumulative operating time, and cleaning frequency is available. Remote firmware upgrades are supported, allowing for device function updates without on-site operation.

● Safety Protection: Equipped with a door control switch (automatic power-off when the equipment cover is opened), a UV leak detector (alarm when the concentration is ≥0.15ppm), and overheat protection for the water cooling system (standard on models with power ≥2kW), providing comprehensive protection for personnel and equipment safety.

Application Scenarios

● Municipal Wastewater Treatment: Installed at the effluent of wastewater treatment plants or in reclaimed water reuse pipelines, it disinfects secondary treated effluent, replacing chlorination processes, reducing disinfection byproducts (such as chloroform), and meeting the standards for reclaimed water use in landscaping and irrigation.

● Industrial Circulating Water: Used in circulating cooling water systems in the power, chemical, and metallurgical industries to kill Legionella and other microorganisms, prevent pipe blockage by biological sludge and equipment corrosion, improve heat exchange efficiency, and reduce makeup water and chemical costs.

● Food Processing Water: Suitable for production water pipelines in beverage, dairy, and meat processing enterprises, disinfecting raw water and cleaning water to prevent product spoilage caused by microbial contamination, meeting food GMP certification requirements.

● Large Swimming Pools and Recreation Water Bodies: Installed in the circulating water systems of large public swimming pools and water parks, reducing chlorine usage (by 50-70%), avoiding chlorine odor irritation and skin allergies, and improving the visitor experience.

● Advanced Drinking Water Treatment: Used in centralized water supply systems in rural towns or small waterworks, deeply disinfecting conventionally treated water, removing residual chlorine and organic matter, ensuring the safety of drinking water at the point of use.

Scope of Application

Precautions for Use

● Installation Requirements: The equipment must be installed horizontally on a straight section of the pipeline, with a straight pipe section of 3 times the pipe diameter reserved before and after to ensure uniform water flow; the pneumatic system must be connected to a clean compressed air source (pressure 0.4-0.6MPa, including an oil-water separator); the remote communication module must be installed in an area with stable signal, avoiding obstructions.

● Operational Safety: Do not open the lamp compartment cover while the equipment is running. Before maintenance, the machine must be stopped and locked via PLC or remote terminal. Operators must wear UV protection glasses and gloves to avoid direct contact with UV rays.

● Maintenance: Check equipment operation data and cleaning records weekly via the touchscreen or remote terminal; check for leaks in the pneumatic system's air hose connections monthly and clean the air filter; calibrate the UV intensity sensor and flow meter every 6 months; replace the lamps according to their lifespan (≥5000 hours) or when the intensity decreases to 70%, ideally replacing the entire lamp to ensure uniform intensity.

● Troubleshooting: If a sudden drop in UV intensity occurs, check for lamp breakage or surface scaling; in case of pneumatic cleaning failure, switch to manual cleaning mode and check the compressed air pressure; if remote communication is interrupted, check the network connection or restart the communication module. If the problem persists, contact the manufacturer's technical personnel.

Frequently Asked Questions (FAQ)

Q: Is the energy consumption high when running at 3kW? Can it save energy?

A: The equipment supports dynamic power adjustment, and can operate at 50% power (1.5kW) during off-peak periods, saving 15-20% energy compared to constant power; moreover, it requires no chemical agents, saving on agent procurement costs compared to chemical disinfection in the long run, resulting in lower overall energy costs.

Q: Does pneumatic cleaning require an additional air compressor?

A: If the user's site lacks a compressed air source, a small air compressor (0.7MPa, 1m³/min) needs to be configured separately. The manufacturer can provide matching options. If a compressed air system already exists, it can be directly connected (an oil-water separator needs to be installed).

Q: Does lamp replacement require professional personnel? What is the replacement cycle?

A: It is recommended that professional personnel replace the lamps. The replacement process requires disconnecting the power supply and draining the water. The operation is simple (completed within 15 minutes). The lamp life is ≥8000 hours (approximately 1 year, based on 8 hours of operation per day). The PLC will issue a replacement reminder 1000 hours in advance.

Q: Can the equipment start normally in low-temperature environments (e.g., -10℃)?

A: Yes. The control cabinet needs to have a heating module that automatically starts at low temperatures to ensure the normal operation of the PLC and communication module. The lamp starting temperature range is -10-50℃. The starting time is slightly longer in low-temperature environments (approximately 30 seconds), but this does not affect the disinfection effect.
