M2–SERIES REVERSE OSMOSIS SYSTEMS

AXEON® M2– Series Reverse Osmosis Systems are a line of high capacity systems with flows ranging from 12,000 to 36,000 gallons per day. These systems are ideal for removing the salt content in well water and surface water for use in commercial and light industrial applications. Using an efficient high pressure pump, the M2– Series systems are engineered for treating brackish water with levels of 10,000 ppm.

M2– Series Reverse Osmosis Systems feature a computer controller that has dual TDS monitoring, low pressure monitoring and alarm, pretreatment lockout, and feed flush and tank level input while larger models include an additional digital flow monitor. All models include low energy reverse osmosis membrane elements, motorized feed valve, permeate sample ports and a bag filter housing with a 5-Micron filter bag.

Some options available for the M2-Series include permeate flush, permeate divert, variable frequency drive, chemical injection system and clean-in-place system.

C. Low temperatures and feedwater quality, such as high TDS levels will significantly affect the systems production capabilities and performance. Computer projections must be run for individual applications which do not meet or exceed minimum and maximum operating limits for such conditions.
D. Product flow and maximum recovery rates are based on feedwater conditions as stated above. Do not exceed recommended permeate flow.
E. Varies with motor manufacturer
F. Does not include operating space requirements.
