Product Description

 

CAF  principle 

  The air floating treatmennt manner is filling air into waste water, in the form of tiny air bubbles precipitine from water as carrier, to make the emulsified oil,small suspended particles etc pollutant  in waste water adhere to  bubble,

Floating upward to water surface with bubble, to form into air,water,particles triple phase mixture,by collecting foam or floating scums to reach purpose of separating impurity,purify waste water.

The floation method  mainly used to treat  emulsified  oil  or relative density near 1 tiny suspended particles which difficult  remove by natural settling or floating ; more widely used in treating oily waste water, it only can remove  particles which bigger than 30~50 um oil drops,smaller oil drops has bigger stability, and it not easy for merge and become bigger floating rapidly,also called emulsifed  oil. The emulsifed oil easy to adhere to air bubble, to increase its floating speed. Thus, the oily waste water treatment set floating technique after grease trap, as to further remove emulsifed oil measure.
   The CAF system is special for removing oil grease,jelly and suspend solids etc in industrial waste water and municipal waste water.  The whole air floating system total divide into five parts, the un-treated waste water flow into CAF small

Air filling section,waste water  fully mixing with aerator produce tiny bubble  in rising process pass by air filling section , aerator make the air in water level  transfer to underwater by air draft pipeline. The aerator working  principal is adopt  exhausting air impeller in air tranfer pipeline high speed rotating to form one vacuum zone, air in liquid level input into water by aerator, filling up vacuum ,

Micro bubble come into being and rise to water level in spiral type, the oxygen in air will dissovled into water. Due to the density  imbalance between  air water mixture and liquid , there will produce one vertical upward flotage, take the SS to water level. In floating process, microbubble will adhere to SS, after reach water level, SS will rely this bubbles support and maintenance it in water level. The 

SS floating in water level will scrape by chain mud scraper.  Scraper move along the whole liquid level,  and make the SS from air flotating tank inlet push to sludge discharge pipeline outlet.  The purified waste water flow into overflow tank. 
  The open backflow pipeline from aeration section extend along air floating tank bottom.  To produce microbubble at the same time, CAF aerator will form into one negative pressure zone in backflow pipeline tank bottom, such negative pressure  function will make sewage backflow into aeration zone from tank bottom,   then return to air flotation section, such  process guarantee 40% waste water backflow and air flotation section also can work in no waste water condition.

Feature:
(1) simple operation, low maintenance cost;
(2)Automatic backflow pipe unique design, to make sludge no easy settling in air flotating tank bottom;
(3) simple system, small investment,high 

Efficiency, steady performance;
(4)to avoid  the  phenomena  air releaser frequently  blocking in DAF. 
(5)Equipment integrity is good, easy installation, saving covers an area of 40% ~ 60%;
(6)Low energy consumption, low operation cost, compared with the dissolved air flotation can save 40% ~ 90% operation cost;
(7)small odor.
(8)  Obvious treatment effect

 Petroleum ,SS removal rate over 80%,BOD COD remove rate can reach over 60%,it can  promote sulfide oxidation, reduce sulphur content in waste water.

 Structure characteristic
  1. Due to the characteristics of the manufacturing solutions, it is high efficiency of the dissolved vapor.
  2. the separation of the mechanism of tiny bubbles generator, raw water, dissolved gas will water and medicine (all line hydrocyclone into) to make a rapid combination, release, flocculation, ascending and floating, tiny bubbles uniform, density, solutions to upper, ascending and floating rate stable zero speed, form the three-dimensional microcirculation state, ensure the tiny bubbles in waste and flocculation body full access, combined.
  3. No matter in combination with process or have combination of floc properties, are not the external force and destroyed their combination, floc properties of floating stability.

Advantage

 

    1, simple operation, high level of integration, there is no complicated machine equipment, high automation and can fully realize the unattended work

    2, high efficiency, low cost of pure water treatment

    3 and low investment, need not auxiliary of the civil engineering and affiliated equipments

    4, low voltage operation, dissolved vapor high efficiency

    5, long-term, stable performance, easy operation, easy maintenance, low noise

    6, multi-layer row mud, make sure the water effect
