Barrier® M UV Systems for Aquatic Applications

The Barrier® M range of UV systems is primarily designed for the treatment of aquatic applications with flow rates ranging from 84 to 4288 US gpm (19 to 974 m3/h).

Barrier® M Series

Ultraviolet disinfection is an ideal alternative to chemical addition systems and can be used as a bolt in multi-barrier approach to your disinfection process.

The Barrier® M UV system provides a cost-effective, operator-friendly solution for low-and-medium flow rate disinfection applications, as well as a chloramines reduction solution for pool water treatment installations. The system consists of a stainless steel reaction chamber with medium-pressure polychromatic lamps, and a remotely mounted microcontroller for complete control and monitoring capabilities. All models except M 35 include automatic quartz cleaning.

The system is effective in controlling waterborne pathogens such as bacteria, viruses, and parasites, including, Cryptosporidium or Giardia, which can be resistant to conventional chemical disinfection. In addition, the system provides a powerful disinfection solution without forming harmful disinfection by-products(DBPs).
