Non-chemical Open Channel Municipal UV Wastewater Disinfection System
Open channel UV disinfection system
With individually removable modules and streamlined hydraulic design, in accordance with the industry standards, Geemblue Open Channel UV Disinfection is a safe, environmentally friendly and effective way to disinfect water. It can effectively reduce the head lose, safeguard the whole system, enjoy good sealing performance, and ensure UV dose delivery. It’s applied in large and medium size wastewater plants, municipal wastewater plants, reclaimed water projects, industrial wastewater, aquaculture farming and other places.
UV Module: Flexible modular design; Easy system integration, installation and operation. The whole module support has shading device. Each complete set of UV lamp module includes UV lamp, quartz tube, stainless steel module frame and online auto-cleaning device. Each UV lamp is put in an individual quartz tube. The quartz tube is fixed on the frame through the seal ring so as to avoid contacting any steel on the frame. The lamps are naturally cooled by the sewage to ensure the work at the same temperature.
UVC lamp: Low pressure amalgam UV lamp. The lamp is the low pressure high intensity UV lamp. Preheating improves the lamp lifetime. 254nm wavelength, more than 12000 hours service life. The lamp is operated and controlled by the electronic ballast of variable power output. The UV output is adjustable between 50%~100%.
Quartz Sleeve & Seal Ring: High transmittance more than 90%. Protection class: IP68; Thickness of tube wall: 1.5mm; The quartz tube nuts have knurling surface for a hold for hands in the tightening; The lamp is assembled and disassembled from one end of the quartz tube. Can be removed without tool.
Electrical Cabinet: Housing material: 304 stainless steel; with voltmeter, timer (non-resettable), leakage Protection, fail alarm system; Ballast (with CE certificate), Automatic UV Intensity Monitoring System, and Central Control System
Auto-cleaning System: The cleaning system is controlled by PLC and can be adjusted by the operator to the cleaning frequency and number of cleanings (Once / 1 ~ 500 hours). Remote manual or automatic cleaning control can be realized through the operation interface and remote control. The cleaning ring is UV-resistant Teflon and Viton rubber, and the metal part is made of 316L stainless steel. The cleaning ring has a service life of more than 3 years.
Automatic Water Level Control System: Including unpowered flaps and low water level sensors.
The unpowered gate uses the bottom outlet to maintain a minimum water level and minimum water level change. Keep the tube completely submerged within this range of variation.
When the water level in the canal is below the set minimum water level for a long time, the low water level sensor can automatically give an alarm and extinguish the lamp.
Features & Advantage
● Cost-efficient frame design, stainless steel material. Individually removable modules. Easy to take out for maintenance and replace.
● Advanced Imported amalgam lamps, more than 12000 hours life time.
● Excellent light transmittance & high-purity quartz sleeves.
● Automatic sleeve wiping system. The wiping sequence occurs automatically at preset intervals without operator involvement excellent performance electronic ballast.
● With its high stability, good heat dissipation, constant UV output, power coefficient over 0.99,variable output (50-100% power), step less regulation and programmable preheated start, it prolongs the UV lamps’ life time more than 20%
● Based system control center continuously online monitors and controls UV lamp status, light intensity, light transmittance and temperature, easy for operator to monitor and control the whole system.
Comparison between Sodium Hypochlorite and UV:
|Parameters||Sodium Hypochlorite (NaClO)||UV|
|Residual toxicity||Toxic to aquatic life.||Non-toxic – UV disinfection dose not add anything to the water, other than light. As a result, the surrounding environment is not harmed in any way.|
|Disinfection By-products (DBPs)||Yes - Same carcinogenic DBPs as chlorine gas. DBPs are not removed or reduced with dechlorination.||None|
|Corrosive||Yes – extremely corrosive||None|
|Community Safety Risks||Low – Due to a limited shelf life, NaClO requires frequent transportation and delivery.||None – Poses no safety threat to the surrounding community.|
|Operator Safety Risks||Moderate – Due to corrosive properties, must be handled and stored with caution.||Low – UV module must be turned off if worker lifts module out of the channel to prevent exposure to UV light.|
|Treatment Performance||Cryptosporidium and Giardia are virtually unaffected. In the past decade, these pathogens have caused disease outbreaks affecting hundreds of thousands of people.||UV disinfection is highly effective against a wide variety of pathogens, including chlorine-resistant organisms such as Cryptosporidium and Giardia.|
|Changing Regulations||Regulations are becoming increasingly stringent in order to limit the amount of chemicals and disinfection by-products in the water. As a result, the operation of chemical-based treatment systems will continue to become more costly and complex.||UV is well suited to meet current and future regulations. The process is safe, simple and does not add chemicals to the water.|
|Residual Removal Required||Yes – Depending on regional regulations. Long-term effects of discharging dechlorinated compounds into the environment are unknown.||No|
|Summary||Hypochlorite has some significant environmental concerns associated with DBPs and residual toxicity. Hypochlorite is not safeguarded against a future tightening of regulations||UV does not add anything to the water, other than light. UV does not create DBPs and is also safe and easy for Operators to maintain.|
