HydroFloat - Dissolved Air Flotation Systems (DAF)
HydroFlo Tech` dissolved air flotation technology, or "DAF", is an effective, economical process for removing hard to separate suspended solids from wastewater and also for resolving overall water clarity issues. A dissolved air flotation (DAF) system resolves suspended solids and clarity issues by reintroducing a slip stream of treated water (from the system`s effluent) back to the system`s influent. This pressurized, recycled water is saturated with dissolved air. When the pressure is released at the system`s influent, the air comes out of solution on the surface of suspended solids particles throughout the dissolved air flotation (DAF) influent mixing chamber. As these billions of micro bubbles come out of solution, they float the suspended solids particle to the surface of the dissolved air flotation (DAF) separation chamber, where they are removed by a surface skimmer.
A DAF can be of circular or rectangular configuration. A well designed DAF treatment system will take up a relatively small plant foot print, and also lead to lower capital and operating costs.
