BLS Series RO Systems are engineered to economically produce high purity water while providing the flexibility to choose system features to meet your application specifications. Units are available as skid mounted, pre-wired, and pre-piped with pre- and post-treatment equipment for a complete water purification package. Skid mounted systems provide maximum efficiency of floor space and reduced installation time and costs. |

* Based on feed water with 500 mg/L of NaCl and temperature of 77ºF (25ºC). |
System production may vary depending upon incoming water temperature and chemistry. |
NOTE: If the RO system is used with chlorinated water, a carbon pre-filter is required. BLS systems are designed for use on potable water sources only. See BLS Parts List. |
