M1 – Series Reverse Osmosis Systems

M1 – Series Reverse Osmosis Systems are designed for overall superior performance, high recovery rates, minimal energy consumption and offer great savings with low maintenance and low operation costs.

The M1 – Series Reverse Osmosis Systems range in capacities from 12,000 to 36,000 gallons per day. To achieve higher recovery rates, each base model includes a concentrate recycle loop. These systems can be upgraded with features such as a variable frequency drive, digital instrumentation, a chemical feed system, blending valve and a permeate divert valve.

* Does not include operating space requirements.

** Varies with motor manufacturer.

† 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.

†† System pressure is variable due to water conditions. Permeate flow will increase at a higher temperature and will decrease at a lower temperature.

††† Product flow and maximum recovery rates are based on feedwater conditions as stated above. Do not exceed recommended permeate flow.
