Our High-Performance Water Treatment Equipment for Solid-Liquid and Liquid-Liquid Separation leverages advanced technology to deliver unmatched efficiency and reliability. The high-efficiency dissolved air flotation machine is designed for the ultimate in separation processes. Through a sophisticated dissolved and release gas system, a vast number of ultra-fine bubbles are produced within the water. These microscopic bubbles attach themselves to solid or liquid particles in the wastewater, which possess a similar density. This crucial interaction significantly reduces the overall density of the particles, allowing them to be effortlessly lifted to the water's surface by the buoyant force of the bubbles. This innovative method ensures superior solid-liquid or liquid-liquid separation, setting a new benchmark in water treatment technology.

WORKING PRINCIPLE:
Our advanced sewage treatment system operates as follows: Sewage is introduced into the gas-liquid contact reaction area of the air flotation machine via a water inlet pump. Within this zone, a gas-liquid mixer generates a profusion of microbubbles, which adhere to oil droplets, suspended solids, and other contaminants. These particles then rise to the surface in the separation zone, forming a layer of scum.
The purified water effortlessly overflows through the overflow weir and exits through the outlet pipe. The surface scum is efficiently scraped by a slag scraper into the scum pool, ensuring a clean and unobstructed water flow.
Subsequently, the scum is transported out using a screw conveyor. For optimal results, continuous scraping is possible, though intermittent scraping is recommended. This approach minimizes the scum's moisture content, reduces scum volume, minimizes interference with the water body, and ensures consistent effluent quality.
ADVANTAGES:
Advantage 1 Exceptional efficiency: The dissolved air flotation machine boasts a short residence time, eliminating the need for backflow water, and occupies a minimal footprint. With a hydraulic retention time of approximately 20 to 30 minutes, it ensures rapid and effective flotation.
Advantage 2 User-friendly design: The dissolved air flotation machine features a simple structure that is easy to operate and maintain. The primary control parameter is the speed of the gas-liquid mixer, which can be centrally managed from an indoor console. This simple operation contrasts with the more complex dissolved air system in conventional flotation processes.
Dissolved air flotation machine has three advantages: Cost-effective and energy-efficient: Our dissolved air flotation machine requires minimal investment and consumes low energy. For a sewage treatment scale of 100m3/h, a single gas-liquid mixer suffices, consuming just 0.75kW. In contrast, conventional pressure dissolved gas flotation systems require multiple components - return water pumps, air compressors, dissolved gas tanks, and intricate piping - resulting in higher investments and energy consumption.
