Chemical treatment systems are crucial methods used to improve water quality and effectively remove pollutants from wastewater. Among these systems, one of the most common and effective techniques is DAF (Dissolved Air Flotation). The DAF system is a water treatment technology that uses microbubbles to clarify water by separating suspended solids (TSS), chemical oxygen demand (COD), and oils from the water.
The DAF water treatment system creates microscopic air bubbles by dissolving air under pressure. These bubbles attach to flocs within the water, causing them to float to the surface and form a sludge layer. Ekosistem Engineering’s specially designed sludge skimming system (aka sludge dewatering system), effectively removes the accumulated sludge from the water surface and transfers it to a sludge pool. The sludge that settles at the bottom is collected by bottom scrapers and sent to sludge collection tanks. Through this process, pollutants are efficiently removed from the wastewater, and the recycled water is transferred to the DAF effluent water tank for use.
Chemical Treatment Methods
Chemical treatment systems start with chemical processes such as coagulation and flocculation. The chemicals used in these processes help small, insoluble particles in the water to combine and form larger, easily settleable flocs. The DAF system then separates these flocs from the water by floating them to the surface with microbubbles. This technique is highly effective, especially in treating industrial wastewater.
There are various techniques and processes among chemical treatment methods, including coagulation, chemical oxidation, and pH adjustment. These methods regulate the chemical composition of water, facilitating the separation and removal of contaminants. Chemical water treatment systems are widely used, particularly in industrial facilities and municipal water treatment plants.
Advantages of the DAF System
- Effective Treatment: Provides high removal rates of TSS, COD, and oils, clarifying and improving water quality.
- Low Operating Cost: Offers energy savings and reduces costs through low chemical consumption.
- Flexibility: Adapts to different water conditions and contaminant concentrations.
- Easy Installation and Operation: It's modular structure allows for easy installation and operation.
