In the world of environmental and water treatment, the term "Sandfloat" refers to a powerful combination of two widely-used technologies: Dissolved Air Flotation (DAF) and Sand Filtration. This innovative system, pioneered by Krofta Engineering Corp., offers an efficient and effective solution for a variety of water treatment challenges.
Dissolved Air Flotation (DAF) is a physical-chemical process that removes suspended solids from water using tiny air bubbles. Air is compressed and dissolved into the water under pressure. When the pressurized water is released into a flotation tank, the dissolved air comes out of solution, forming microscopic bubbles that attach to the suspended solids. These buoyant particles then rise to the surface, forming a layer of sludge that is easily removed.
Sand Filtration is a physical process that removes suspended solids from water by passing it through a bed of granular media, typically sand. The sand traps the particles, providing a clear effluent.
By combining these two technologies, the Sandfloat system offers numerous advantages:
1. Enhanced Treatment Efficiency: DAF pre-treats the water, removing larger particles and reducing the load on the sand filter. This extends the filter's lifespan and minimizes the need for backwashing, leading to improved overall efficiency.
2. Improved Water Quality: DAF effectively removes fine suspended solids, oils, greases, and other contaminants that are difficult to remove with sand filtration alone. The combined system provides a higher quality effluent, meeting stringent discharge standards.
3. Reduced Operating Costs: The pre-treatment provided by DAF reduces the frequency of sand filter backwashing, leading to lower water consumption and energy costs. The system also minimizes chemical usage, further reducing operating expenses.
4. Compact Design: The Sandfloat system is designed to be compact and modular, making it suitable for various applications, including municipal wastewater treatment, industrial wastewater treatment, and potable water treatment.
