The operation process of the air float can be divided into three stages:
Bubble generation: The bubble generator converts air or oxygen into tiny bubbles in a specific way. Adhesion of bubbles to Suspended particles: These bubbles come into contact with suspended particles in wastewater in the reaction zone of the air float and adhere to the surface of the particles.
Flotation and separation of the flotation body: because the density of the flotation body is less than water, it will be gradually floated to the surface of the water by the action of buoyancy. In the floating and separation stage, the flotation body gathers on the water surface to form scum, which is scraped from the water surface by a slag scraper or other equipment, so as to achieve solid-liquid separation.
Equipment features:
Efficient solid-liquid separation: The air float uses the buoyancy of the gas to lift the solid particles or liquid aggregates suspended in water to achieve solid-liquid separation, which has higher separation efficiency than traditional precipitation, filtration and other separation methods.
Wide range of application: air float is widely used in sewage treatment, pulp manufacturing, food processing, paper industry and other fields, can meet the sewage treatment needs of different industries.
Simple and convenient operation: The operation process of the air float is simple, and only the pressure of the gas and the size of the bubble need to be adjusted to achieve the solid-liquid separation of the suspended matter, and the entire operation process has no complex operating steps.
Large treatment capacity: a single air float can handle a large amount of treatment, and multiple air floats can be combined to achieve large-scale sewage treatment.
Application areas:
Air floats have a wide range of applications in sewage treatment, including but not limited to:
Chemical wastewater treatment: remove heavy metals, organic pollutants and other pollutants in wastewater to reduce the burden of subsequent treatment.
Flotation: In the treatment of mine wastewater, it can be used in the flotation process to achieve the separation and recovery of ore.
Sludge concentration: By injecting bubbles, the sludge particles float to achieve sludge concentration and reduction.
Dissolved gas removal: removal of dissolved gases in sewage, such as carbon dioxide, hydrogen sulfide, etc.
Care and maintenance:
In order to ensure the normal operation of the air float and extend the service life, regular maintenance and maintenance are required. It mainly includes:
Check whether the inlet sewage pump and return pump are frozen, and lubricate the pump, tighten the packing, seal the bottom valve and fuel the air compressor.
Check whether the air filter valve is frozen, determine whether the air compressor is running normally, and whether there is noise and heating.
Check the drive part of the scraper and the scraper to avoid hardening and breaking in cold conditions.
Pay attention to the coagulant mixing tank, avoid freezing, and often do sample tests.
Check the valve pipes of each device to avoid clogging the valve pipes, and place them in the "open" or "off" position as required.
