providing a total solution for the customer.

Company’s priorities are

honesty, professionalism, safety and innovation. We

are committed to finding the best solution and insist

on keep on exploring water treatment equipment

technology. Our product and the total solution can

be applied in all kind of industrial wastewater

treatment field such as petrol, chemicals, pharmacy,

food processing, leather, dyeing, paper making

industries etc.

Company is following the

example of advanced technology of Europe and

America and embraces research, development and

design by themselves. We develop a series of

separation system such as HDAF, SDAF, integrated

DAF and Lamella clarifier etc. On the basic of the

above mentioned reliable and advanced

technology, we also explore coagulation &

flocculation reactor and dosing system.

Company adheres to constantly pursue the innovation of technology and manufacturing processes. The ideal of quality man-management system runs through the whole process of product design, manufacturing, and maintenance. We control every step of process strictly and produce the firs class equipment and systems.

DAF Process

Dissolved Air Flotation is a liquid/solid or liquid/liquid separation process.

It can be used to remove fine suspended solids with density similar to

water, colloid and oil & grease etc.

Removal is achieved by dissolving air (in high pressure) in the form of tiny bubbles (10-100um for micro bubble and 10-100nm for nano bubble) in the wastewater. The micro/nano bubbles adhere to suspended matter causing the suspended matter to float to the surface of the water and form a layer which is then removed by a skimmer. The forth-free water exits the flotation tank as the clarified effluent from the DAF unit.

DAF Applications

Fine suspended matter, alga and micro flocs separation ( such as

landscape water treatment, river clarifying and enhanced treatment)

Suspended solids and oil & greases separation and recovery ( such as

petroleum wastewater, biodiesel and restaurant wastewater)

High concentration organics wastewater pretreatment (such as

chemical, pharmacy wastewater)

Outlet wastewater from biological tanks (replacing secondary clarifier),

outlet wastewater from the Fenton process and active sludge thickening

Paper & pulp, printing & dyeing, leather, fermentations, food wastewater

treatment

Aquaculture, slaughter wastewater treatment

Spray, electroplating wastewater treatment and heavy metal recovery

IAF is a technology specialized in removing high concentration oil & grease and SS in industrial wastewater. The untreated wastewater enters into an aeration segment with aeration equipment at first. The vacuum effect will be created by a high speed rotation air impeller when the wastewater is in the progress of up-flow and air sucked into the cavity of the impeller. Then the micro bubbles will be generated by attrition. The micro/nano bubbles will attach to suspend matter in the wastewater and float to the water surface. The suspended matter will be removed by special skimmer.

Mechanism

IAF--- Cavitation Air Flotation

No noiseNo circulation pumpNo air compressorNo air-dissolving containerNo underground pipelines

Core technology Application

Adventages

SAF unit is a highly efficient shallow air flotation system adopting the “shallow tank theory” and “zero-speed principle” successfully. Under a certain pressure the air will excellently dissolve into the water until saturated.The water pressure is lowered in high efficiency air releaser, which produce high amount of micro-bubbles. The produced micro/nano-bubbles and the suspended matter attach to each other and float to the surface of the water. The suspended matter will be removed by a special skimmer. The depth of the shallow tank is only 450-600mm and HRT is about 3-5min, which will reduce retention time and improve flotation efficiency greatly.
