Representative KONCHE UV projects (client names anonymized):
In-line UV disinfection delivered for a food plant's purified-water line in Dongguan.
Total bacteria counts stay reliably in specification and the plant passed its customer audit. Lamps are replaced on an 8,000–10,000 operating-hour schedule, keeping annual maintenance cost in the low hundreds of RMB.
| Item | Cycle | Maintenance |
|---|---|---|
| System check | Quarterly | Check lamp status, intensity, ballast and alarm response. |
| Quartz sleeve cleaning | Every 3–6 months | Clean scale and deposits to maintain UV transmission. |
| UV lamp | 8,000–10,000 operating hours | Replace according to operating hours and intensity trend. |
| Electronic ballast | Continuous | Check current, temperature and alarm state during routine service. |
No. UV provides disinfection. Filtration or RO is required for particles, dissolved salts and other impurities.
A fine filter is recommended when particles or turbidity may reduce UV transmittance.
No. UV is chemical-free and does not leave a disinfectant residual, so downstream protection and hygiene should be considered.
Selection uses flow, UV transmittance, target dose, water temperature, pressure and installation conditions.
Since 1997, Konche has supplied 254 nm low-pressure sterilizers for food, pharmaceutical and process water — in-line units sized by flow, transmittance and dose.
Each system is designed around the water analysis, industry standard, site condition, capacity and final use.
Component selection, factory testing, water-quality verification and process control are managed as one complete system.
KONCHE supports proposal alignment, technical documentation, consumables supply, maintenance guidance and remote operational clarification.
Send your water analysis, target capacity and application. Konche will help select and configure the suitable system.
