Superficial DAF

Product Details

Superficial DAF, a dissolved air flotation system designed with a shallow tank that uses about 40% less installation area than conventional systems, focusing on separating floated sludge at the water surface. Suitable for limited spaces and for adding to existing systems, complete with a built-in micro bubble generation system and automatic sludge scraper blades. It removes more than 90% of FOG and SS and efficiently reduces BOD/COD.

Key Features: Superficial DAF
  • Shallow tank, using about 40% less area than Horizontal DAF
  • Separates surface sludge and removes more than 90% of FOG/SS
  • Built-in micro bubble generation system and automatic sludge scraper blades
  • Automatic operation and easy control
  • Easy to install or retrofit into existing systems
Benefits: Superficial DAF
  • Installs in limited spaces or reinforces existing systems
  • Reduces structural work and basin depth (low CAPEX)
  • Reduces the FOG/SS load on downstream systems
  • Saves space and installation costs
Working Principle: Superficial DAF
  • 1. Wastewater passes through coagulation-flocculation.
  • 2. Pressurized air-saturated water releases micro-bubbles that attach to the flocs.
  • 3. The flow path is designed to separate sludge at the surface within the shallow tank.
  • 4. Floating sludge is skimmed off automatically while clarified water is discharged from below.
Supported Industries
  • Food and beverage plants
  • Central kitchens and service businesses
  • Retrofit projects on existing systems
  • Sites with limited installation space that still need DAF performance
Product Highlights
  • Shallow tank design, saving installation area and depth
  • Easy to install, suitable for limited spaces and retrofitting existing systems
  • Efficiently separates sludge at the water surface
  • Integrates a built-in micro bubble generation system and automatic sludge scraping

Static Screen
PRE TREATMENT

Static Screen

The Static Screen / Wedge Wire Screen is used for preliminary wastewater treatment, using gravity to separate solids from wastewater without electricity and with no moving parts. It is made of SUS304 stainless steel wedge wire screen, with selectable slot openings of 0.25–3.0 mm, supporting a maximum flow rate of approximately 270 m³/hr. It helps reduce TSS and protects pumps and valves in the treatment system.

PRE TREATMENT

Rotary Screen

The Rotary Screen (External Fed Rotary Drum Screen) is a rotating drum screen for continuous and automatic separation of fine solids from wastewater. It uses a stainless steel wedge wire screen with openings of 0.25–3.0 mm, supports wastewater with high oil or grease content, and comes with a scraper blade and water spray system to help reduce clogging.

Internal Drum Screen
PRE TREATMENT

Internal Drum Screen

The Internal Fed Rotary Drum Screen is a high-efficiency drum filter in which wastewater is fed from inside the drum and separated to the outside, providing gentle flow that reduces the break-up of flocs and fragile solids. The screening basket is inside and the structure is entirely stainless steel, designed with a tightly sealed cover so odour can be controlled. It is suitable for wastewater containing soft or fibrous solids.
