Rectangular DAF Plant System
The 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. Below is a detailed explanation of how the Rectangular DAF plant system functions:
How It Works
- 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.
