Product Introduction
TPZF combined air flotation Machine consists of air floatation tank, dissolved air system, dissolved air return pipeline, dissolved air water release device, scraping device (combined, driving and chain plate according to user needs) and electric control cabinet. In the water supply and drainage treatment process, solid and liquid separation technology and machine are one of the key projects. Air flotation is one of the most effective methods for the removal of tiny suspended particles with a specific gravity close to that of water.
Usage
The equipment is suitable for white water pulp recovery and water reuse of paper industry, removal of various heavy metal ions, refinery wastewater, oil pollution separation, impurities in tannery wastewater, color and impurities of printing and dyeing wastewater, various biological treatment, biological mud film Solid-liquid separation, sludge concentration (The treatment capacity is 30%-50% of machines capacity), etc.
Working principle
Air-floating separation technology means that air and water are dissolved in water under a certain working pressure, and the air is dissolved in a state of saturation. Then, the formed pressure-dissolved water is released by decompression, and a large amount of fine bubbles are generated. It is in full contact with the suspended flocs in the water, so that the suspended flocs in the water adhere to the micro-bubbles, and float to the surface with the bubbles, forming into scum and then scraping it off, thereby purifying the water.
Air floatation mainly acts as a solid-liquid separation (while reducing COD, BOD, chromaticity, etc.). The flocculant PAC or PAM is added to the raw water, and after the effective flocculation reaction (the time, the amount of the flocculant and the flocculation effect must be determined by the experiment), the raw water enters the combined air-floating contact zone. In this zone, the micro-bubbles in the dissolved air and the flocs in the raw water adhere to each other and enter the separation zone together. Under the action of the buoyancy of the bubbles, the flocs rise together with the bubbles to the liquid surface to form into scum. The scum is scraped by the scraper to the sludge zone. The lower layer of clean water flows through the collecting pipe to the clear water pool. Some of the wate
Main Features
- Small occucaption, low power consumption, convenient operation and simple management;
- The dissolved air has high efficiency and stable treatment effect, the machine, electricity and instrument are realized in integrated control.
- The device adopts TPZF type dissolved air system. It has a ingenious structure, and the efficiency of dissolved air can reach over 90%. It has numbers of patented technologies, and has excellent anti-blocking capability that other dissolved air devices do not have.
- Also, the device adopts a new dissolved air releaser, which has high air releasing perfection and the average particle size of microbubbles is only 15~30 microns.
- The device adopts chain plate scraper, which is stable and reliable in operation and high in scraping efficiency.
