The Best Rectangular DAF plant system is an advanced water treatment technology designed for the removal of suspended solids, oils, and other contaminants from water. It operates based on the principle of flotation, utilizing air bubbles to lift particles to the surface for removal.
At Ishan Paryavaran Private Limited, we are dedicated to environmental innovation, and our Rectangular DAF (Dissolved Air Flotation) system exemplifies this dedication. Engineered with precision and incorporating cutting-edge technology, the Ishan Rectangular DAF system sets new benchmarks for performance, efficiency, and reliability, serving as a cornerstone in modern water treatment processes.
Introduction of Air: Air is introduced into the water stream under pressure, creating micro-sized air bubbles dispersed throughout the water.
Contact with Contaminants: Air-saturated water enters the Rectangular DAF tank, where it comes into contact with suspended particles and contaminants.
Attachment of Air Bubbles: Micro-sized air bubbles attach themselves to the suspended particles and contaminants present in the water.
Formation of Float: Buoyant aggregates form a froth or foam layer on the surface of the water, trapping suspended particles and contaminants.
Skimming: Once the float layer reaches a certain thickness, it is carefully skimmed off the surface of the water using mechanical scrapers or skimmers. These devices collect the float and direct it to a separate chamber for further processing or disposal.
Clarified Water Collection: Beneath the float layer, the clarified water, now substantially free from suspended solids and contaminants, is collected from the bottom of the Rectangular DAF tank. This clarified water typically undergoes additional treatment processes, such as filtration or disinfection, before being discharged or reused.
Rectangular Tank: The core element of the Rectangular DAF system, facilitating the flotation process by efficiently mixing air and water and separating float from clarified water.
Scrapers/Skimmers: Mechanical apparatus employed to eliminate the float layer from the water surface, ensuring continuous operation and effective removal of contaminants.
Air Dissolution System: Equipment tasked with pressurizing and saturating water with air, crucial for generating air-saturated water essential for the flotation process.
High Efficiency: The Rectangular DAF system delivers exceptional contaminant removal efficiency, yielding clarified water of superior quality.
Versatility: Adaptable to a broad spectrum of applications, ranging from municipal wastewater treatment to various industrial processes, the Rectangular DAF system can be customized to fulfill specific water treatment requirements.
Space Efficiency: Its streamlined design makes it well-suited for installations with space constraints, optimizing the utilization of available footprint.
Low Maintenance: Characterized by robust construction and straightforward operation, the Rectangular DAF system demands minimal maintenance, thereby reducing downtime and operational expenses.
