Quality Dissolved Air Flotation Water Treatment System in Adelaide
At Freshwater Systems, we offer dissolved air flotation water treatment services in Adelaide to remove suspended matter, grease, and rubber substances in sewage. The dissolved air flotation (DAF) water treatment treats industrial wastewater from oil refineries, chemical plants, and food and beverage industries. Freshwater Systems has offered DAF services since 1991. We pride ourselves on being the leading manufacturer and distributor of water treatment equipment in Adelaide. We are a locally-owned and operated business but gradually gaining traction throughout wider Australia.
With extensive experience in the water treatment industry, Freshwater Systems provides custom fabricated and designed plants and unmatched attention to detail. Our staff members come with unique expertise, making us an all-around team that you can trust to deliver your water treatment project on time. Not only that, our prices are competitive, and we offer customised quotes.
The Standard Process of Dissolved Air Flotation Water Treatment in Adelaide
Adelaide’s dissolved air flotation water treatment works by separating suspended solids and lighter liquid contaminants from water using air bubble flotation. Air is dissolved into water, mixed with the waste stream and released from the solution while in intimate contact with the contaminants.
Air bubbles attach to the solid contaminants, increasing their buoyancy and floating them to the water’s surface. The pollutants are then mechanically skimmed and removed from the tank. We then recycle and super-saturate the clean effluent with air mixed with the wastewater influent and inject it into the DAF separation chamber.
Our team then injects pressured air into a recycled stream of clarified DAF effluent. The recycle stream combines and mixes with incoming wastewater in an internal contact chamber where dissolved air comes out of the solution in the form of fine bubbles that attach to the contaminants. The bubbles and the contaminants rise to the surface and are removed by a surface skimmer into an internal hopper.
Call Us for Dissolved Air Flotation Water Treatment in Adelaide
When designing dissolved air filtration water treatment in Adelaide, our experts consider many criteria for sizing, including;
- Flow rate
- Water temperature
- Waste characteristics
- Chemical pre-treatment
- Solids loading
- Hydraulic loading
- Air to solids ratio
DAF systems are designed based on the peak flow rate expected. For instance, the flow rate can be three or four gallons per minute per square foot of surface area. This rate also determines the chemical pre-treatment that improves solids removal efficiency.
At Freshwater Systems, we manufacture DAF systems for various projects like food courts and processing plants, dairy product industries, and abattoirs. Our system offers unmatched performance and reliability. We have worked and completed DAF units for several projects, including Adelaide Oval, Tea Tree Plaza Shopping Centre, and Drake Meats.
