The Effect of Nano Bubble Technology in Water Treatment

Technical principle: By using special devices to cut gases such as air and oxygen into micro nano level bubbles, these bubbles have a large specific surface area and high surface energy, which can greatly increase the contact area between gas and water, thereby improving the efficiency of oxygen dissolution.

Oxidative decomposition of pollutants: Micro nano bubbles exist in water for a long time, continuously releasing oxygen, increasing the dissolved oxygen content in the water, promoting the growth and metabolism of aerobic microorganisms, accelerating the decomposition and mineralization of organic matter, and reducing pollutant concentrations.

Strong oxidizing properties: When micro nano bubbles rupture, they produce strong oxidizing substances such as hydroxyl radicals, which can oxidize and decompose pollutants such as organic matter, ammonia nitrogen, and sulfides in water, and also have bactericidal and disinfecting effects.

Physical function: The movement and rupture of micro nano bubbles in water can generate micro water flow and micro jet, which can promote the mixing and circulation of water, improve the fluidity and self purification ability of water, and at the same time, adsorb and remove suspended solids, colloids and other impurities in water, improving the transparency of water.

Equipment advantages

Excellent bubble characteristics: small bubble diameter, large specific surface area for gas-liquid mass transfer, and high efficiency; Bubbles rise slowly and stay in water for a long time, which is beneficial for increasing the concentration of dissolved oxygen in water and can also reduce sediment.

Reliable equipment performance: The overcurrent components are made of corrosion-resistant materials such as SUS304 stainless steel/316L stainless steel, with industrial grade design that can operate continuously for 24 hours, stable and reliable. It also has GPS remote intelligent control function, without the need for WiFi or card insertion. The dedicated CPU integrated motherboard can automatically control water, electricity, and gas parameters.

Accurate and controllable: Taking the experimental micro nano aerator as an example, it supports small-scale and high-precision aeration volume adjustment, can be refined to the millimeter level, can meet the aeration intensity requirements of different water samples, and can stably generate micro nano bubbles with uniform diameters, ensuring consistent key parameters for each experiment.

Integration and Intelligence: The ozone micro nano bubble generator adopts an integrated design of machine, electricity, water, and gas, with new integrated technology and one click start. The equipment reaches saturation state in a short time, with high efficiency and energy saving.

Application scenarios

River ecological restoration: Through the "in-situ restoration system", the micro nano bubble generator is equipped with intelligent deployment equipment to release oxygen rich micro nano bubbles into the water, activate indigenous microorganisms, accelerate the decomposition of sediment pollutants, and enhance dissolved oxygen in the water. In a certain black and odorous river treatment project, the dissolved oxygen in the water increased from almost 0 to over 4mg/L, and the black and odorous phenomenon disappeared.

Industrial wastewater treatment: For highly polluting industries such as printing and dyeing, chemical engineering, etc., a coupled process of "micro nano bubbles+advanced oxidation" is designed. The bubbles carry active substances such as ozone and hydroxyl radicals, enhancing the removal of chromaticity and COD. In a certain printing and dyeing wastewater treatment project, the COD removal rate increased from around 60% to over 90%.
