Quick Answer
The Alpha UV STP UV Disinfection System is a multi-lamp UV-C system for sewage treatment plant final effluent, sized from 10,000 to 2,00,000 LPH, CPCB-compliant at less than 100 MPN/100 mL, with SS316 chamber and remote SCADA monitoring — no chemicals required.
CPCB-compliant UV tertiary disinfection for sewage treatment plants — closed-vessel and open-channel
Sewage treatment plant final effluent must meet CPCB discharge norms of less than 100 MPN/100 mL total coliform before surface water discharge or reuse. UV disinfection is the CPHEEO-recommended tertiary treatment technology for all STP scales — it delivers this standard without chlorine dosing, without DBP formation, and without the chemical storage and safety hazards of sodium hypochlorite. Alpha UV STP UV systems use a multi-lamp UV-G array in an SS316 stainless steel closed-vessel chamber sized for peak hourly STP flow rates from 10,000 to 2,00,000 LPH. For large municipal STPs above 500 KLD, open-channel UV configurations are available. Every system is sized by IIT Patna engineers from measured effluent UVT and turbidity — not from generic STP-capacity tables. Remote monitoring provides real-time UV intensity, flow rate, and alarm status via 4–20 mA SCADA or cloud dashboard.

Every Alpha UV System reactor geometry is validated through CFD simulation using ANSYS Fluent. The analysis below shows velocity streamlines and UV dose distribution across the reactor cross-section, confirming that minimum dose targets are met across the entire chamber volume — not just at the chamber centreline.

Every STP UV ships with genuine Philips UV-C lamps. Not unbranded Chinese alternatives. Philips lamps are rated 9,000–12,000 hours — more than double the life of typical Chinese OEM lamps. A serial number certificate of authenticity is included with every lamp.

A UV disinfection system in an STP inactivates pathogens — bacteria, viruses, and protozoa — in treated sewage effluent using UV-C light at 254 nm, as the final tertiary treatment stage before discharge or reuse. It requires no chemical dosing and produces no disinfection byproducts.
CPCB discharge norms require STP final effluent to contain less than 100 MPN/100 mL of total coliform before surface water discharge. UV disinfection at 40 mJ/cm² achieves 4-log E. coli reduction — reliably meeting this standard from secondary-treated effluent.
The STP UV Disinfection System supports closed-vessel configurations from 10,000 LPH to 2,00,000 LPH. For municipal STPs above 500 KLD requiring open-channel UV, custom multi-unit designs are available from IIT Patna engineers.
Yes. For STPs above 500 KLD where open-channel installation is preferred, Alpha UV supplies open-channel UV-C module banks designed to DWA A 143 and CPHEEO methodology. IIT Patna engineers calculate lamp spacing, immersion depth, and module count from your measured effluent UVT.
