Integrated Dissolved Air Floatation Machine Small Printing and Dyeing Sewage Treatment Equipment Slaughter Sewage Treatment Equipment

I. basic introduction of dissolved air floatation machine

Integration of dissolved air flotation machine adopt stainless steel material manufacturing equipment, air flotation machine adopts integrated sewage treatment system, is a set of multi-function set molding equipment, widely used in industrial and municipal wastewater treatment, can effectively remove the oil in the wastewater, acid and alkali, jelly, suspended solids, BOD and COD, and its water quality is good, can reach the standard.

Ii. Principle of air floatation machine for production waste water treatment equipment

Air flotation, also known as air flotation, is a commonly used flotation method in sewage treatment.The commonly used bubble formation methods can be divided into water pump suction pipe suction air float, diffusion plate aeration air float, jet air float and impeller air float machine.

A process in which the hydrophobically contaminated ions contained in a polyphase system such as sewage, pollutants and bubbles are selectively adsorbed from the wastewater to the bubbles and separated from the water in the form of foam.Air flotation is a water treatment technology that produces a large number of micro bubbles into the water or through electrolysis to make them adhere to the solid or liquid pollutant particles with a density close to that of water in the waste water to form an air floating body with a density less than that of water.Air flotation is mainly used to remove relatively dense suspended solids, oils and fats from wastewater. It can also be used to concentrate high concentration wastewater and then dry it by belt filter press.

The pollutant particles in the wastewater can be adsorbed on the bubbles and float up with the bubbles in a stable manner, which is a prerequisite for the separation of air flotation. Therefore, the removed pollutant particles should have a hydrophobic surface.In order to improve the separation effect of air flotation, often take measures to change the solid or the liquid contaminants on the surface properties of particles, to add a certain number of suspending agent, the water make the hydrophilic particles into hydrophobic particles, cic to emulsified oil wastewater and demulsifier (coagulant), makes difficult to gather gas floating emulsified oil in removal of suspended solids.
