Product Description

Air flotation working and system principles:

Air flotation separation is to mix air and water under certain pressure and conditions, so that the gas can be dissolved into the water to the maximum extent, striving to be in a saturated state, and then the pressure-dissolved water formed can be released through a special device to rapidly produce a large amount of gas. The micro bubbles are in full contact with the floating matter in the water (flocculation after dosing). Under the action of "net catching", "wrapping" and "bridging" of the purple particles, the bubbles and the floating matter form a stable The density of the air-entrained floc is smaller than that of water, so the air-entrained floc quickly rises to the water surface, and the floating matter condenses into scum on the liquid surface. The scum is scraped and removed to achieve the purpose of solid-liquid separation.

• What is the characteristic of floc formed after adding medicine to the floating matter in the water body? Is it hydrophilic or hydrophobic (appropriate dosing).
• During the mixing reaction, ensure that there are enough micro bubbles in time and full contact with the flocs
• During the separation reaction, the solid, gas, and liquid mixture should have an appropriate residence time and a stable flow pattern to allow the "air-entrained floc" to float to the liquid surface and form scum. Controlling the flow state of liquid is one of the keys to the separation effect.

Features

• Overall complete set, compact structure, cost-effective market retention, high maturity, stable performance, reliable operation.
• Hydraulic load: 4~6m²/(m²/h).
• Allowable concentration of floating matter can be up to 3000mg/L.
• Floaters can realize automatic skimming, solid content can be as high as 30-l0mg/L applied to solid flocs density is generally lighter than water or close to water, precipitation phenomenon is weak water quality.

Application Scenarios

• Industrial wastewater pretreatment: food processing, pharmaceuticals, textile printing and dyeing, semiconductors, machinery,steel, chemical industry, aquaculture and other industries wastewater;
• Sewage treatment plant: sewage pretreatment, upgrading, phosphorus removal;
• Water treatment plant: algae removal;
• Ecology: river, lake purification, landscape water treatment;
• Desalination project.

Technical Parameter

Application Cases

Industry:Workshop cleaning wastewater

Project Name:Toyota Motor

Capacity: 3m3/h

Product Name: Standard air flotation DAF

Case Introduction: Toyota Machinery Workshop Cleaning Wastewater Treatment

Characteristics of workshop cleaning wastewater: Containing oil, organic matter, surfactant, cleaning agents and other difficult to degrade substances, as well as residual metal ions on the equipment, sediment and other solid particles and other fine residues, polluting rivers and lakes, and destroying the natural ecological environment.

In this project, with the use of our standard sedimentation type air flotation to sedimentation and separation of sediment and other large particles, while the suspended matter and other further enhancement of the treatment to improve the hydraulic load, to achieve efficient solid-liquid separation.

Sector: Slaughtering Wastewater

Project Name: Laoduo Chicken Fast Food

Capacity: 20m3/h

Product Name: Standard air flotation-DAF

Case Introduction: Laoxiang Chicken Slaughtering Wastewater Treatment Case

Laoshiang Chicken, the largest fast food chain in Anhui Province, has a signature dish - "Feixi Old Mother Hen Soup". Laoxiang Chicken is a catering industry featuring breeding ten chickens, and the main components of the catering wastewater are leftover food and water, with starch, food fiber, animal fats and other organic matter as the main components, which are characterized by high nutrients, high water content, high oil and salt content, and easy to decay and fermentation and odor.

Laoxiang chicken attaches great importance to environmental protection, to realize green production, our company suggests the use of standard air flotation design to solve a large number of breeding, catering wastewater, in addition to a large number of suspended solids in food wastewater SS and oil and grease, to ensure that the latter part of the depth of the treatment system for the stable operation of the discharge of the standard!
