What are the key features of the flow-through UV water disinfection system

  1. Continuous on-line treatment: Water flows continuously through the reactor chamber without retention tank. It can be installed in circulating pipelines, ideal for swimming pools and recirculating water systems.

  2. Physical disinfection, no chemical dosing: UV light damages microbial DNA/RNA. It does not change water pH and produces no disinfection by-products such as residual chlorine or chloroform.

  3. Easy integrated installation: Pipeline type design with flange or thread connections, installed in series in the pipeline, compact footprint.

  4. Fast reaction: Disinfection is completed during short UV exposure inside the chamber. The effect depends on UV dose instead of long static contact time.

  5. Simple maintenance: Main tasks are periodic UV lamp replacement and quartz sleeve cleaning for scale removal. No bulk consumables or chemical dosing systems.

  6. Water quality prerequisite: Turbidity, suspended solids, iron and manganese will block UV transmittance. Poor water quality reduces disinfection efficiency; pre-filtration is recommended.

  7. Instant disinfection only: UV provides no residual biocidal effect. Microbes may regrow in downstream pipelines. Swimming pool application usually requires low-level chlorine for residual protection.

  8. Safety protection: Sealed reactor prevents UV leakage. Equipped with ballast, UV intensity monitor, and optional automatic cleaning unit.
