INTRODUCTION

The flotation tank is usually made of high-quality carbon steel or stainless steel, possessing good corrosion resistance and sturdiness, providing a stable space environment for the entire flotation process. The dissolved air system is the core part, which can efficiently dissolve air in water to generate dissolved air water, laying the foundation for the subsequent separation of impurities. The scum scraping device can timely scrape and collect the pollutants floating on the water surface, ensuring the continuous and stable flotation effect. The water distribution system ensures that the sewage to be treated can be evenly distributed in the flotation tank, while the drainage system is responsible for discharging the treated clean water.

This equipment comes in a variety of specifications and can be flexibly selected according to factors such as the sewage treatment volume, water quality characteristics, and site space. It is widely applicable to the treatment of various industrial wastewater and domestic sewage. It has the advantages of easy installation, relatively simple operation, and stable and reliable operation, making it an ideal choice for the efficient removal of pollutants such as suspended solids, grease, and colloids in sewage.

WORKING PRINCIPLE

The working principle of high-efficiency horizontal flow flotation machines is based on the flotation separation technology. Firstly, the sewage enters the flotation tank from the inlet. Meanwhile, the dissolved air system generates a large amount of dissolved air water, and the dissolved air water releases tiny bubbles at the bottom of the flotation tank through the release device.

These tiny bubbles will fully contact and attach to the suspended solids, grease, colloids, and other pollutants in the sewage during the rising process. Due to the buoyancy of the bubbles, the bubbles attached with pollutants will gradually float to the water surface to form a scum layer. Subsequently, the scum scraping device will scrape and collect the scum layer from the water surface, realizing the separation and removal of pollutants. After the flotation treatment, the clean water with most of the pollutants removed will be discharged from the flotation tank through the drainage system, thereby achieving the purpose of purifying the sewage and significantly improving the content of suspended solids and the clarity of the water quality, creating favorable conditions for further treatment or meeting the discharge standards.

MAIN PERFORMANCE AND CHARACTERISTICS

l High-Efficiency Separation Capacity: Thanks to the tiny and uniform bubbles generated by the dissolved air system, it can achieve good attachment with various pollutants in the sewage, and has an excellent separation effect on suspended solids, grease, colloids, etc. It can quickly remove a large number of impurities in the sewage, significantly improve the purification efficiency of the sewage, effectively reduce the pollutant content of the sewage, making it easier to meet the discharge standards or the water quality requirements for subsequent reuse.

l Stable and Reliable Operation: The overall structural design is reasonable, and each component is of reliable quality. Whether it is the dissolved air system, the scum scraping device, or other supporting systems, they can maintain stability during long-term operation, are not prone to malfunctions, and can adapt to changes in water quality and quantity. They continuously provide a stable treatment effect for sewage treatment work, reduce treatment interruptions or water quality fluctuations caused by equipment problems, and the maintenance cost is also relatively low.

l Simple and Easy Operation: The operation process of the equipment is not complicated. Workers only need to control the relevant parameters and operation sequence of the water inlet, dissolved air, scum scraping, and drainage processes. There is no need for complex professional knowledge and skills. Ordinary personnel can master the operation method proficiently after simple training, facilitating its promotion and use in various sewage treatment sites.

l Strong Adaptability: According to different sewage sources, water quality characteristics, and treatment scales, the operation parameters such as the amount of dissolved air water generated and the flotation time can be flexibly adjusted. It can also be used in combination with other sewage treatment equipment. Whether it is dealing with industrial wastewater from chemical, printing and dyeing industries or domestic sewage, it can find suitable application methods, has good versatility, and can meet diverse sewage treatment requirements.

l Small Footprint: The horizontal flow structural layout makes the equipment use space more reasonably. Compared with some other types of flotation machines, under the same treatment scale, it usually occupies a smaller area. This is undoubtedly a great advantage for sewage treatment projects with limited site space, enabling more flexible installation and layout.

APPLICATION FIELDS AND INDUSTRIES

l Industrial Field: In the chemical industry, a large amount of wastewater containing various chemical substances, suspended solids, and grease is generated. High-efficiency horizontal flow flotation machines can effectively remove these pollutants in the wastewater, reduce the burden on subsequent treatment processes, improve the efficiency of the entire wastewater treatment system, enable the wastewater to meet the discharge standards better, and avoid causing serious pollution to the environment. The wastewater in the printing and dyeing industry contains a large amount of dyes, auxiliaries, and fiber impurities. Through the treatment of the flotation machine, the suspended solids and some poorly soluble dyes in the wastewater can be removed, improving the biodegradability of the wastewater and facilitating the subsequent biochemical treatment process.

l Municipal Sewage Treatment Field: Domestic sewage contains sediment, grease, colloids, and various domestic sundries. High-efficiency horizontal flow flotation machines, as important equipment in the pretreatment or advanced treatment process, can further purify the sewage, remove the suspended solids and grease in it, improve the water quality of the sewage, ensure that the final effluent quality of the sewage treatment plant meets the discharge standards, reduce the impact on the surrounding water environment, and protect the ecological environment.

l Food Processing Industry: The food processing process generates wastewater containing a large amount of organic matter, grease, and suspended solids. This flotation machine can quickly separate the grease and suspended solids in the wastewater, reduce the pollution degree of the wastewater, and at the same time, the recovered grease can be reasonably utilized, realizing the recycling of resources and the effective treatment of sewage, meeting the requirements of the green development of the industry and improving the environmental protection benefits of enterprises.

l Aquaculture Industry: Aquaculture wastewater contains a large amount of feces, uneaten feed, and suspended solids and other pollutants. High-efficiency horizontal flow flotation machines can pretreat it, remove most of the suspended solids and some organic matter, reduce the load on subsequent treatment processes, enable the aquaculture wastewater to pass through the subsequent biochemical treatment, disinfection, and other processes more smoothly, and achieve the discharge standards, avoiding adverse effects such as eutrophication on the surrounding water bodies.

SUMMARY

High-efficiency horizontal flow flotation machines, with their unique structure, reliable working principle, and many excellent performance characteristics, have shown an indispensable role in sewage treatment work in many important fields such as industry, municipal, food processing, and aquaculture. They are like the capable forces in sewage treatment, quietly contributing to improving the water environment, promoting the rational utilization of water resources, and the sustainable development of various industries. With the continuous progress of science and technology, it is believed that high-efficiency horizontal flow flotation machines will continue to make breakthroughs in aspects such as improving treatment efficiency, increasing the degree of automation, and expanding applications, further meeting the increasingly diverse sewage treatment needs of society and becoming one of the key supporting equipment for creating a high-quality water environment and promoting the development of the environmental protection cause.
