Solar Aeration System Core components
Water and air to exchange gaseous substances and water to remove volatile substances in the water, or to escape the gas from the water, such as removing water.
Odor or carbon dioxide and hydrogen sulfide and other harmful gases; or oxygen into the water, in order to improve the dissolved oxygen concentration, to achieve iron, manganese or promote the purpose of aerobic microbial degradation of organic matter.
The factors that affect the rate of gas transfer between gas and liquid are: the partial pressure of the gas in the gas phase and the concentration, temperature, the interfacial area and the composition of the water in the liquid phase. At the same temperature and partial pressure, the solubility of a gas in water (often referred to as equilibrium concentration) is constant; when the concentration of the gas is greater than the equilibrium concentration, it escapes from the water; when the concentration is less than the equilibrium, the gas is dissolved in water The Reservoirs or lakes tend to smell due to the propagation of algae, protozoa and plankton, or the rot of animal and plant debris. Toxic substances are usually volatile organic matter, can be used fountain, multi-level water, multi-layer perforated plate water and multi-layer coke pan fell into the water and other aeration device, so that the water dispersed into a thin film or droplet and remove it.
Groundwater sometimes contains hydrogen sulfide, carbon dioxide or excess iron, manganese, can also be treated with aeration. Free carbon dioxide is corrosive, low water alkalinity, the aeration of water can be filtered through the limestone filter, so that carbon dioxide into carbonate, then the filter bed to have a longer contact time. Groundwater dissolved iron, manganese is generally low-cost bicarbonate, and air contact, due to reduced free carbon dioxide concentration and dissolved oxygen concentration increased, that can be converted into precipitation. Iron, manganese content is generally not high, little oxygen, so the requirements of aeration, while the contact time is higher.
The former is compressed air through the pipeline and cloth equipment in the water to form small bubbles, floating up through the water layer. The latter is the application of impeller or rotary brush vigorously stirring the water, constantly with the new interface and atmospheric contact, bubble aeration method and surface aeration method in addition to oxygen, but also has a stirring effect, so that the activated sludge to maintain the suspended state. See the structure and equipment of the aeration tank see the activated sludge method. In addition, the bubble aeration method is also used for wastewater treatment plant grit chamber to wash sediment and prevent the destruction of waste water.
Aeration system of the core components of the aeration pump suction port can use negative pressure suction gas, so no need to use air compressor and atmospheric injector
The The high-speed rotating pump impeller mixes the liquid with the gas, so no agitator and mixer are required. As the pressure inside the pump mixture, gas and liquid fully dissolved, the dissolution efficiency of up to 80 ~ 100%. So no large pressure dissolved gas tank or expensive reaction tower can be made a high degree of dissolved solution. Gas-liquid ratio of about 1: 9 (suction volume of 8-10%), the use of series can increase the amount of inspiratory. A GLM (B) series of aeration pump can be gas-liquid to attract, mix, dissolve and send a high degree of dissolved solution directly to the point of use. Pump flow 1-50 M3 / H; treated water 1-150 M3 / H. Therefore, the use of GLM (B) series aeration pump, can improve the efficiency of dissolved gas production, simplify the preparation device, save space, significantly reduce the initial investment, save operating costs and maintenance costs.
