Nuvonic ProLine Series Drinking Water and Wastewater Reuse UV Systems

Nuvonic ProLine is a range of third-party validated or certified UV systems in two application groups: municipal drinking water disinfection (PQ AF, PQ AL, PQ EO, PQ IL, PQ IL DVGW) and wastewater reuse (PQ WW AL, PQ WW IL). For drinking water, UV is used worldwide as a Cryptosporidium barrier, because even at low doses it protects against chlorine resistant pathogens such as Cryptosporidium and Giardia. Mikron Proses (Üsküdar, Istanbul) offers the range with model selection, supply and commissioning.

ProLine WW IL, the basic wastewater model without third-party validation, has its own page: Nuvonic ProLine WW IL. Every variant on this page has a 316L stainless steel chamber, flanged process connections and an automatic wiper.

Five drinking water variants, five levels of validation and capacity

PQ AF is a low energy, single-lamp amalgam range for small communities (3 models, 200-750 W). It has a dry DVGW approved UV sensor and an RS 485 Modbus interface, and its dose equations and sizing are validated to the USEPA UV Disinfection Guidance Manual.

PQ AL gives higher capacity for small to mid-sized communities with a multi-lamp low pressure design (4 lamps in PQ AL 100, 12 lamps in PQ AL 300). Stepless lamp power adjustment from flow and UVT meter inputs optimises energy use.

PQ EO gives high treatment capacity with a single medium pressure lamp (5 models, PQ EO 4 to 12, 4.5-6.8 kW). The UV sensor has a UVGuard™ window that allows a safe audit while the system is running, and UVShield™ power cut-out and water leak detection are optional.

PQ IL and PQ IL DVGW are compact medium pressure designs for small to mid-sized communities where space is tight. PQ IL is USEPA validated and lists NSF 61 among its approvals (6 models, 5.6-52 kW); PQ IL DVGW is DVGW certified (7 models, 1.8-52 kW). Both have a dry DVGW compliant UV sensor; on PQ IL there is one per lamp.

NWRI validation for wastewater reuse

PQ WW AL (2 models, PQ WW AL 100 and 300, 2.4-7.2 kW) and PQ WW IL (9 models, PQ WW IL 250 to 18000, 5.6-117 kW) serve tertiary disinfection after sand filters or membrane filters. The PQ WW IL datasheet states third-party validation to the National Water Research Institute (NWRI) standard across a wide range of dose, flow and UVT parameters. For PQ WW AL, the datasheet states NWRI validation for the PQ WW AL 100 model only. An optional Ultrawipe (chemically enhanced wiper) for PQ WW IL keeps the quartz sleeves clean in water with high fouling potential. Compared with chlorination, UV avoids generating potentially harmful by-products and supports the production of water for irrigation, aquifer recharge or direct reuse.

Power by variant (datasheets)

Variant	Number of models	Maximum power	Lamp
PQ AF	3	200-750 W	Low pressure amalgam, 1 lamp
PQ AL	2	2.4-7.2 kW	Low pressure, 4 or 12 lamps
PQ EO	5	4.5-6.8 kW	Medium pressure, 1 lamp
PQ IL	6	5.6-52 kW	Medium pressure
PQ IL DVGW	7	1.8-52 kW	Medium pressure
PQ WW AL	2	2.4-7.2 kW	Low pressure, 4 or 12 lamps
PQ WW IL	9	5.6-117 kW	Medium pressure

The datasheets give lamp power and number of models, not flow capacity. Flow selection depends on UVT and the disinfection target, and is done per project.

Which variant (which validation standard, which capacity) suits your process depends on the plant flow, the UV transmittance and the discharge or reuse standard. Describe your requirement and we can select the model together.
