Daf Unit 100m3/H Dissolved Air Flotation Unit Integrated Daf System Dissolved Air Flotation System

Overview
The flat Air flotation machine is a kind of water purification method, which produces a large number of fine bubbles in the water through the dissolved air water produced by the dissolved air system after rapid decompression release. Some bubbles stick to the surface of the flocculated eurotic particles in the water and form suspended solids with the overall density less than 1. Through buoyancy, it rises to the water surface and separates solid and liquid. Efficient shallow air floatation device is based on the traditional air floatation theory, and the successful use of "shallow theory" and "zero speed" principle, through careful design, set coagulation, air floatation, slag, precipitation, scraping mud as one, is a high efficiency water purification equipment.

Air floatation system collects water, flocculation, separation, water collection, water in one, similar to the traditional air floatation equipment, with a stable flow chamber, dissolved gas release chamber, so that the treatment performance is more stable, better effect, especially suitable for the transformation of traditional equipment.

Stable room: through the folded plate of raw water, flow rate is very high, if direct contact with the dissolved air water, will dissipate the tiny bubbles and influence flocculant bubbles from block effect, thus reducing gas float processing efficiency, if increased the steady flow chamber, the turbulent kinetic energy consumption, raw water into the dissolved air water release chamber at a constant speed, so as to guarantee the removal efficiency.

Dissolved gas release chamber: dissolved gas release chamber and separation chamber in a tank. Separated in the middle, the dissolved gas water and the raw water after flocculation adhere here, rise slowly, and enter the air flotation separation chamber, ensuring the space and time for the contact between the flocculant and the tiny bubbles, so that the release rate of the dissolved gas water can reach 80-100%

Dissolved gas system: For air flotation equipment, dissolved air flotation equipment in gas system is the "heart", and one of the main parts of air flotation equipment, in this phase, gas and water in the inlet of the pump suction, together with the impeller shear pressurized dissolved air water mixture, gas-liquid two-phase mixture and fully saturated dissolved air system of a complete set of air content of 10%, and the solubility of a gas is 100%, The microbubbles are evenly distributed and the average bubble diameter is less than 30um. The dissolved gas system is an improvement and technological innovation of the traditional air floatation system, which improves the air floatation separation efficiency and greatly reduces the equipment production and operation costs.

Slag scraper: the operation mode and speed of the slag scraper directly affect the ice quality and sludge solid content of air surfaced water. The system adopts rotary slag scraper, can continuously and evenly scum Scraping into the scum trough reduces the collision phenomenon of floating channels; In addition, the height adjustable scraper can better adapt to various operating conditions, reduce the sludge moisture content.

Control system: all adopt well-known electrical components to ensure long-term effective operation of equipment. Supporting equipment air flotation agent and dosing equipment is also an important reason to ensure the treatment effect We can provide matching dosing equipment and optimized combination of agents according to the needs of users.
