Dissolved air flotation (DAF) is one of the most popular techniques used by industries in Melbourne to treat wastewater. Basically, it removes suspended matter—solids, oil, etc.—from effluent by dissolving air in the water under pressure and then releasing it at atmospheric pressure in a flotation tank basin. Due to its efficiency, DAF is now used by a wide range of industrial facilities, from chemical plants to oil refineries. So, how is DAF water treatment Melbourne has been applied in treating wastewater?
- Pre-Treating Wastewater
The main application of DAF in an industrial facility would be pre-treating wastewater before discharging it to a biological treatment system or the sewage system. In most cases, contaminants need to be chemically flocculated to be removed from effluent, and DAF would be the best technology to use for this purpose. You can use such a method with an industrial discharger, so you will be able to meet specific limits set by the government for suspended solids. Click here Aero Float
- Reducing Chemical Oxygen Demand
DAF water treatment in Melbourne is also used in reducing chemical oxygen demand (COD) that is found in the colloidal material, biological sludges, and similar forms of organic matter. Aside from this, such method has also seen a great deal of success when used in delicate processes, such as manufacturing pharmaceutical and chemical products.
- Removing Biological Solids
This method of treating wastewater has proven to be very effective in removing biological solids from sludge streams. In fact, it is found to be a better alternative to traditional, gravity clarification methods for several reasons. According to research, DAF allows for more rapid implementation; has smaller footprint; has better ability to handle bulk solids that would float; produces higher content of sludge solids, which results to lower sludge volume; and is more reliable in terms of effluent quality.
- Getting Rid of Metals and Low pH Elements
If you are engaged in coal mining, you are producing acidic water that is highly contaminated with metals or runoff that contains elements with very low pH values. If these types of effluent migrate into the streams, rivers, or the sea, it would not only affect the quality of these bodies of water but would also pose a health threat to the people living in the surrounding communities. By employing DAF water treatment in your operations, you will be able to mitigate these contaminants.
