DUV/N Series

DUV/N Series consist of standard pressurized UV equipment for low and medium capacities designed for disinfection of natural water, industrial and wastewater, with UV transmittances between 50% ≥ τ ≥ 90% at a wave length of 254 nm.

Below table shows the preliminary equipment selection of DUV/N Series for disinfection of various water qualities at customer required UV dose and known UV transmittances (τ) at a wave length of 254 nm.

All basic equipment is intended to operate under 10 bar pressure and completed with UV sensors.

Reactors of standard DUV/N Series systems are made of stainless steel AISI 304.

Optionally the UV reactor can be made of steel AISI 304, AISI 316 or AISI 316L or AISI 316TI with any flange orientation (DL, DZ, Z, U, L) and operating pressure up to 20 bar.
