Mobile Combination Reverse Osmosis Treatment Unit

Evoqua Water Technologies' mobile combination reverse osmosis (RO) treatment systems combine pretreatment vessels and RO units in a single, self-contained trailer.
​Evoqua's mobile combination reverse osmosis (RO) treatment unit is a self-contained, trailer-mounted system configured with both pretreatment and reverse osmosis capabilities. The trailer makes low conductivity water at 200 gpm or it can be configured as a 90 gpm, double-pass unit to reduce extensive DI polishing costs on high TDS feed water.

The pretreatment vessels may be configured in parallel or series. Depending on the media of choice, they may act as multi-media filters, activated carbon filters, iron removal filters, or as ion exchange softeners.

​Evoqua Water Technologies guarantees the quality and quantity of produced water from its mobile treatment systems. A reliable and extensive service network, an ever-expanding trailer fleet and strategically located regeneration facilities allow Evoqua to effectively serve our large North American customer base.
