Effektiv opløst luftflotation (DAF) vandbehandling til plastgenbrug

Hvad er opløst luftflotation (DAF)?

Opløst luftflotation (DAF) is a highly effective water clarification process widely used in treating wastewater from various industrial sources. At its core, DAF technology works by dissolving air into water under controlled pressure. When this air-saturated water is subsequently released into a flotation tank at atmospheric pressure, millions of microscopic air bubbles are formed. These tiny bubbles readily attach to suspended contaminants in the water – such as oils, grease, solids, and even fine microplastics. The buoyant force of the combined bubble-particle agglomerates causes them to rise to the surface, forming a sludge layer that can be easily skimmed off. The result? Significantly clearer effluent water, ready for reuse or safe discharge. This simple yet powerful principle makes DAF a cornerstone of modern wastewater treatment.

DAF: A True Game-Changer for Plastic Recycling Facilities

Plastic recycling operations, by their nature, generate wastewater laden with challenging contaminants like fine plastic particles, residual oils, inks, adhesives from labels, and other suspended solids. Discharging this water without adequate treatment can lead to environmental harm and hefty non-compliance fines. Dissolved Air Flotation (DAF) systems offer a robust and reliable solution to these challenges, bringing multiple benefits:

How Dissolved Air Flotation Works Its Magic: A Step-by-Step Look

The DAF process is elegantly simple yet highly effective. Raw wastewater first enters the system, often after preliminary screening. To optimize performance, especially for very fine or emulsified particles, chemical pre-treatment using coagulants (like Polyaluminium Chloride – PAC) and flocculants (like Polyacrylamide – PAM) may be applied. These chemicals help tiny particles clump together into larger ‘flocs’, making them easier for the air bubbles to capture. The core DAF process then unfolds in clear stages:
