Dissolved Air Flotation Water Treatment: How it Works & Repair Signs

Summery

Dissolved air flotation is an advanced water treatment process that helps remove suspended solids from the wastewater. It works in multiple steps to ensure a good water quality; However, you have to provide timely servicing or repairs to keep it running smoothly.

Dissolved air flotation (DAF) is a widely used and vital component of your water treatment plant. Industries like F&B, pulp & paper, chemical & petrochemical, and pharmaceuticals use this system to treat wastewater in Sydney. If you want to install this system in your water treatment plant, it is essential to know about the system to make an informed decision.

What is Dissolved Air Flotation Water Treatment?

DAF is a water treatment method that uses air bubbles for water purification. The bubbles remove contaminants like oil, grease, and suspended solids to the surface of the water.

How It Works

• First, chemicals are added to the water to help the small particles float.
• After that, air is pumped into the water while it is under pressure. This helps air to dissolve into the water.
• Then, the water is released into a tank at normal atmospheric pressure. This pressure drop causes the dissolved air to form countless bubbles.
• These small bubbles attract the impurities and attach to them. As the bubbles float on the top of the water, it becomes easier to remove them.
• Finally, the pure water was collected from the bottom of the tank.

Signs Your DAF Water Purification System Needs Repair

Just like other water treatment systems, this also needs time-to-time servicing and repair. Here are the signs that tell you to hire the experts:

• Increased Chemical Consumption: This system requires coagulants or flocculants to work properly. If you have suddenly noticed, this system has increased the chemical consumption; this is a sign that the chemicals are not being properly mixed or the system is less efficient. Our experts can address the issue and make sure your system is working efficiently. Contact us to learn more about our services.
• Higher Energy Costs: This system involves many components. Inefficient pumps, air compressors, or motors can lead to higher energy consumption. You can’t fix this with some DIY tricks; only an expert can navigate the complexities and replace the inefficient part safely.
• Excessive Sludge: If the volume of sludge generated is higher than expected, this can also lead to increased disposal costs. Let our experts handle this issue to save money from further disposals.
• Ineffective Purification: Improper purification can lead to higher levels of suspended solids, oil and grease, or other contaminants. This also indicates that professional servicing is required for your DAF system.
