Dissolved Air Flotation System

Dissolved Air Flotation System (DAF) is an efficient flotation method for water clarification. The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure. When the pressure is released the solution becomes supersaturated
with air as millions of small bubbles form. These bubbles attach to any particles in the water causing their density to become less than that of water. The particles then rapidly float to the surface for collection and removal, leaving the clarified water behind.

Product Introduction
Dissolved Air Flotation System (DAF) is an efficient flotation method for water clarification. The term
refers to the method of producing flotation by dissolving air in the water under pressure and then
releasing the pressure. When the pressure is released the solution becomes supersaturated
with air as millions of small bubbles form. These bubbles attach to any particles in the water
causing their density to become less than that of water. The particles then rapidly float to the
surface for collection and removal, leaving the clarified water behind.

Features

Flow rate of one set: 1-150m³/h.

High efficiency pressurization system providing high quantity dissolved-air water to create large quantities of micro bubbles.

Custom design on different dissolved air flotation equipment and recycle flow ration according to the typeof wastewater and treatment requirement to achieve target removal effect and stability.

Adjustable nylon or stainless steel chain typeskimmer to suit the different quantity of sludge.

Integrated coagulation and flocculation tank and cleaning water tank(as optional).

Automatic and remote controllable.

Material of construction:

Carbon steel(epoxy painted)

Carbon steel(epoxy painted)+FRP lining

SUS304

SUS316L

Application

DAF system is a proven, and effective physical-chemical technology commonly used for many industrial and municipal applications, including:
