DAF Water Treatment Equipment Offers Extensive Applications

Posted on February 7, 2020December 27, 2020

Dissolved air filtration systems – DAF, is a commonly used wastewater clarification method that separates suspended solids including fats, oil and grease while reducing the COD and BOD level of the sewage. These water treatment systems work by dissolving air in the wastewater under high pressure, whereby the air bubbles will attract the solids causing them to suspend on the surface. From here the sludge can be removed using surface scraping mechanism.

DAF Water Treatment Equipment Offers Extensive Applications

DAF wastewater treatment systems can be used for a variety of applications to ensure municipal and environmental compliance. This technology is highly effective with buoyant particles and solids that are relatively less dense. DAF offers efficient solids removal which is especially important in the production of light, high-volume solids that are resistant to settling.

DAF is among the recommended industrial water treatment systems and compared to conventional clarification methods, it performs much better. That’s why it’s used across a number of industries including food and beverage, petrochemical, chocolate factory, meat processing among others.

Features of a Typical Containerized DAF System

A good DAF wastewater treatment system comes designed with the essential features for the utmost efficiency. Some of these key features are:

  • Chemical pre-treatment stations
  • Dissolved air flotation reactor
  • Side channel compressor
  • Sensors
  • Dosing pumps
  • Control panel
  • Cylindrical shape to prevent dead zones

Three factors to consider when choosing a DAF wastewater treatment system.

Installation

When choosing a DAF system it’s important to ensure that it comes fully assembled with all the essential components of the treatment technology readily installed. This makes allows the system to be easily disassembled and move to another location if necessary. You only need a level base to ensure proper installation and efficient power supply.

Operation

Unlike conventional systems that required mechanical skimmers, the modern DAF plant is fully automated to allow self-cleaning and removal or floatation sludge. It’s a heavy-duty system that can support different wastewater flows and withstand high temperatures. Some DAF systems will also come with chemical mixing stations for proper chemical mixing, which helps to cut down the energy costs. With additional modules, the capacity of a DAF plant can be significantly increased to meet varying production levels.

Maintenance

Choose a DAF wastewater system with low maintenance. A good dissolved air flotation manufacturer will offer onsite training to you or your staff to ensure proper equipment handling, operation and better performance. The best thing about these systems is that their replacement parts are easily available with interchangeable options from local brands.
