A skid-mounted water-treatment unit for small-scale applications

The R5 dissolved-air flotation (DAF) unit (photo) is modular and skid-mounted with variable tank sizes, flow and recycle rates to provide a customized, flexible solution for smaller water and wastewater treatment operations, pilot-plant testing and backup for unexpected plant equipment breakdowns. The new DAF unit supports projects requiring reduced lead time, or where upfront costs for a fully customized design are prohibitive. The unit is suitable for pilot testing in potable water, tertiary wastewater, industrial process water and pretreatment for reverse-osmosis or nanofiltration. The main components are skid-mounted with the DAF unit, and are customizable with several options, including screw conveyor, standby pump and materials of construction. Recycle flowrates can vary from 25–375 gal/min. DAF treatment is effective for clarifying suspended solids or contaminants where the specific gravity of is close to, or less than, 1.0 — such as oils, grease, algae and other low-density solids. — WesTech Engineering Inc., Salt Lake City, Utah
