Industry Applications
Conclusion: Low-pressure high output (LPHO) flow-through UV has low maintenance cost; medium-pressure (MP) flow-through UV has relatively high maintenance cost.Maintenance cost mainly consists of lamp replacement, quartz sleeve cleaning, spare parts and labor cost.
UV lamp: Long service life (9,000–12,000h), long replacement interval. Unit lamp price is low and lamp is the main consumable.
Quartz sleeve: Only regular cleaning required (monthly/quarterly for swimming pool), rarely needs replacement.
Electrical components: Stable electronic ballast with low failure rate and few spare parts consumption.
Labor: Simple operation, short time for sleeve cleaning and lamp replacement.
Application: Swimming pool, potable water and conventional water treatment with economical long-term operation cost.
UV lamp: Short service life (3,000–6,000h), frequent replacement. Unit lamp price is much higher than LPHO lamp, consumable cost accounts for a large proportion.
Quartz sleeve: Higher operating temperature, easier scaling and aging, higher replacement possibility.
Electrical & cooling system: High-power ballast, some equipped with cooling system, more components and failure points, high spare parts cost.
Labor: High equipment power, higher requirements for maintenance and lamp replacement.
Application: Advanced oxidation (AOP), chloramine degradation, TOC removal and other special requirements, higher maintenance budget required.
Water quality: High hardness and suspended solids → easy scaling on sleeve, more frequent cleaning
Operation mode: Frequent start-stop accelerates lamp aging and increases consumable cost
Quality of material and accessories: High-quality ballast and quartz sleeve reduce replacement frequency
