Product Description

Super Subsurface Daf Unit Patent Technology Dissolved Air Flotation

The super subsurface dissolved air flotation success of R&D in Oct. 2003, and won the advanced technology patent protection in 2007, the patent number: ZL2007 2 0155718.3.
The super subsurface DAF won the reputation of technology innovation products, and get the SEPA (state environmental protection administration) strongly recommend products in 2008.
The super subsurface DAF is a masterpiece unit of water treatment field, it's widely used waste water treatment industry, especial in pulp&paper industry. It's for the SS(suspended solids) removal rate closed to 100%, for COD(chemical oxygen demand) removal rate over the 85%.
Application fields:

Primary and secondary treatment of industry waste water;
All of the liquid contain with the SS(suspended solids);
Instead of the primary desilter of Chemical Pulping;
Treatment of the waste paper in pulp&paper mill  
Feature and advantage
Highest rate for the SS trapping (Be closed to 100%)
Higher sludge concentration (Max. 12%)
Can be absorb a big of the waste water unsteadiness
Low power and chemical consumption.
Modular components add to increase production.

KS Air flotation clarifier is a special design, the top open rectangular air floatation clarifier by suspended particles and dissolved air flotation and the suspended solids from liquid separation device of integrated by special equipment. By wastewater from sewage pump before into the feeding chamber and the circulating water through a special device evenly mixed.
Pressure release point at the bottom of the air floatation tank pressurization dissolved air water before mixing with the required processing wastewater. After released into the atmospheric pressure, dissolved air water release the micro bubbles, form to remove tiny ideal suspension of bubble size.
