Welcome to our presentation of the 5 cubic meter per hour Dissolved Air Flotation water treatment system. Designed for plastic recycling operations, this compact and efficient unit ensures high-quality water reuse by effectively removing suspended solids, oils, and grease from wastewater. Its modular design allows for easy integration into existing washing lines, making it an ideal solution for sustainable recycling processes.
These are the dosing tanks for Poly Aluminium Chloride (PAC) and Polyacrylamide (PAM). These chemicals play a crucial role in coagulating and flocculating contaminants, enhancing the flotation process. The PAC neutralizes charges on particles, while PAM binds them into larger flocs, facilitating their removal by the microbubbles generated in the flotation tank.
Upon activation, the system pumps wastewater into the flotation tank, where compressed air is dissolved under pressure. As the air is released, millions of fine bubbles form, adhering to the flocs and causing them to rise to the surface. A scraper then removes the floating sludge, leaving behind clarified water that can be recycled back into the washing line.
This DAF system offers significant advantages for plastic recycling operations. By treating and recycling water on-site, it reduces water consumption and lowers operational costs.
In summary, our 5 cubic meter per hour DAF water treatment system is a reliable and eco-friendly solution for plastic recycling plants.

Frequently Asked Questions
How does the dissolved air flotation (DAF) process work?
Wastewater is pumped into the flotation tank, where compressed air is dissolved under pressure. As the air is released, millions of fine bubbles form and adhere to the chemically formed flocs, causing them to rise to the surface. A scraper then removes the floating sludge, leaving clarified water that can be recycled back into the washing line.
What chemicals does the system use?
The dosing tanks hold Poly Aluminium Chloride (PAC) and Polyacrylamide (PAM). PAC neutralizes the charges on suspended particles while PAM binds them into larger flocs, which the microbubbles can then lift to the surface. Together they greatly enhance the flotation process compared with air alone.
What contaminants does it remove?
The system effectively removes suspended solids, oils, and grease from plastic recycling wastewater. These are the main pollutants generated by washing lines, and removing them is what makes the treated water clean enough to reuse in the wash loop.
What is the treatment capacity?
This model treats 5 cubic meters per hour. It suits small to mid-size washing lines; operations with larger water flows should look at the 20 m³/h DAF system for a higher-capacity option.
How does the DAF unit integrate with an existing washing line?
The modular, compact design allows easy integration into existing washing lines. The unit takes wastewater from the wash loop, treats it, and returns clarified water to the line — a closed loop that reduces both fresh-water intake and effluent discharge without major re-plumbing.
What maintenance does the system require?
Routine tasks include refilling the PAC and PAM dosing tanks, inspecting the scraper mechanism, and checking the air dissolution system for consistent microbubble generation. Regular sludge removal from the surface keeps separation performance stable over time.
