Last Updated on February 4, 2019CRYSTAL CLEAR™ Quartz Sleeves used in the MEGATRON® Water Disinfection System protect and insulate the ultraviolet lamps. These sleeves allow for high germicidal UV output over a range of temperatures. A fouled up quartz sleeve blocks the UV radiation from passing into the water. Since water quality varies greatly from site to site, it can be difficult to determine when it is time to clean quartz sleeves. The MEGATRON® comes equipped with a patented wiper mechanism to easily accomplish the quartz sleeve cleaning. Both manual and automatic cleaning can happen while the MEGATRON® is fully operational, continuing to provide water disinfection.
3 Methods to Determine When to Clean Quartz Sleeves
- Method 1: Visual inspection of quartz sleeves after one week of operation. Re-check weekly until fouling is spotted. The inspection period of time can then determine the cleaning cycle. Quartz sleeves should be cleaned 3/4 of the time that it takes for fouling to occur. For example, if fouling is visible after 4 weeks, clean every 3 weeks.
- Method 2: Intensity level displayed by the optional GUARDIAN™ Digital Monitor will decline from green “UV Normal” to red “UV Low.”
- Method 3: A rise in the total bacteria count from test samples will be present.
2 Methods to Determine the Frequency of Quartz Sleeve WipingMethod 1: For most applications, set the cycle to wipe once a week for clean quartz sleeves.
- Simplest way to make sure that the quartz sleeves remain clean.
- If the monitor continues to show a drop in UV output, or water tests reveal a rise in the bacteria count, increase the wipe cycle to twice a week.
- Repeat this procedure until the GUARDIAN™ monitor only shows a small drop in intensity, or water tests indicate an acceptable bacteria count.
Method 2: Watch the monitor intensity reading.
- Set the cycle time for wiping the quartz sleeves at about half the time it takes for a significant drop in the UV meter. For example, if the ultraviolet meter drops into the red zone after 96 hours, the cycle time should be set to 48 hours.
- This method can also be checked with a water test to determine if the bacteria exiting the unit are at an acceptable level. For grime that the wiper is not improving, remove the quartz sleeves from the unit one at a time and rinse with a mild detergent or citric acid. Sleeves can be hand wiped or dipped into a cleaning tank, then rinsed with water. Stubborn stains can be removed using a dilute hydrochloric acid.
Benefits of the Optional Automatic Wiper
- Program for up to 6 wipe cycles per day, 7 days per week.
- Takes this regular maintenance task off of the staff’s to-do list.
- The cleaning mechanisms are operated by pneumatic cylinders driven with compressed air.
- A patented Teflon® wiper blade is fitted around each quartz sleeve and all wipers are driven along the length of the sleeve, at the same time.
