The new R5™ dissolved air flotation unit – pre-engineered, modular and skid-mounted with variable tank sizes, flow and recycle rates – offers users a customised, flexible, easy-to-install, and affordable solution for smaller municipal and commercial water and wastewater treatment facilities, plant pilot testing, as well as backup for unexpected plant equipment breakdowns.
Recently released by WesTech Engineering, Inc., an employee-owned leading provider of municipal and industrial solutions for water and wastewater treatment, liquid and solid separation, and biological treatment needs, the R5 DAF unit supports projects that require a reduced lead time, or where upfront costs for a fully-customised design is too expensive.
The unit is ideal for pilot testing in applications including potable water, tertiary wastewater, industrial process water, small communities and camps, and pretreatment to reverse osmosis and nanofiltration. Due to its flexibility, the R5 DAF is a perfect fit for smaller commercial and industrial operations like breweries, wineries, dairies, food processors, refineries and laundries.
The main components are skid mounted with the DAF unit to minimise installation requirements, and are customisable with several options, including screw conveyor, standby pump and material of construction, among others. Moreover, recycle flow rates can be set up to vary from 25 to 375 gpm, depending on system needs.
Dissolved air flotation is ideal in clarifying water and wastewater where the specific gravity of suspended solids or contaminants is close to, or less than 1.0, and can remove low-density solids such as oils, grease, algae, among others. Additionally, DAF can also be applied to wastewater clarification, sludge thickening, product recovery, filter backwash recovery, and algae removal, among others.
“The pre-engineered DAF units come in several tank sizes and recycle rates,” Michael Vanderhooft, an Engineer with WesTech, said. “These standardised units are designed to fit any application, providing a custom solution at an affordable price.”
