🔷 Product Description
DAF System Overview

DAF (Dissolved Air Flotation) operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the 'float', is skimmed off as sludge. The clarified water is removed from the bottom and is sometimes called the subnatant or 'floated' water.

Since rain, snow, wind or freezing could cause problems with the float, flotation tanks must be fully enclosed in a building. The process is particularly suited to treatment of eutrophic, stored lowland or otherwise algae laden waters and soft, low alkalinity upland coloured waters. Flotation performance depends on the effectiveness of coagulation and flocculation.

🔷 Frequently Asked Questions
Q1: What is the primary function of the DAF system? The DAF (Dissolved Air Flotation) system is designed to remove suspended solids, oils, and grease from wastewater by attaching micro air bubbles to flocs, causing them to float to the surface for removal.
Q2: Which industries can benefit from using this flotation machine? It is widely used in paper mills, food and beverage processing, oil and gas industries, tanneries, slaughterhouses, and municipal sewage treatment plants.
Q3: What materials are used in the construction of the QK-DAF? The system is typically constructed using high-quality Carbon Steel or Stainless Steel (S 304/S 316) for key parts to ensure durability and corrosion resistance.
Q4: How does the system handle low water temperatures? Polyelectrolyte dosing is often included to compensate for reduced performance at low temperatures or if the floc is fragile, ensuring consistent water quality.
Q5: Is technical support available for equipment selection? Yes, professional engineers provide technical support and assistance in type selection to ensure the equipment meets specific project requirements.
Q6: Can the flotation tanks be installed outdoors? Because environmental factors like rain, snow, or wind can affect the 'float' layer, it is highly recommended that flotation tanks be enclosed within a building.
