What is aeration in wastewater treatment? This is a process of forcibly transferring oxygen in the air to the liquid, and its purpose is to obtain sufficient dissolved oxygen. In addition, sewage aeration has the purpose of preventing the sinking of suspended bodies in the tank and strengthening the contact of organic matter in the tank with microorganisms and dissolved oxygen.
What are the common types of the wastewater treatment equipment? 1. Blower aeration: Using a certain air volume and pressure, the blower aeration forces the gas into the water or liquid through the conveying equipment. 2. Mechanical aeration: The oxygen in the atmosphere enters the liquid by the mechanical action of blades, impellers, sprayers or turbine devices. Currently widely used aerators mainly include surface aerators and submerged turbine aerators. 3. Combined aeration: For example, combined aeration combined with blower and mixing device: static aerator, fixed spiral aerator, etc. 4. Jet aeration: The water pump passes through the jet aeration. The noise is small, the general machinery is adopted, and the installation and use are relatively simple. 5. Bubble aeration device.

What you need is what we can do: Tube aeration device, cyclone aerator, aeration plate, jet aerator, jet aeration system JAS, surface aeration equipment, blast aeration equipment, water-dropping aeration, undERWater aeration equipment, Pure oxygen aeration equipment and deep well aeration equipment; Spherical corundum microporous aerator, aeration turntable for Orbal oxidation ditch; Aeration brush for Pasveer oxidation ditch: Kessener brush and Mammoth brush; Pumping aerator, microporous aeration plate, mechanical aeration. PETROL STEEL CO., LTD can supply the above Floating Surface Waste Water Aerator with 7*24hours service for you.
What are the functions of aeration equipment? Difference between Diffused Air vs. Mechanical Wastewater Aeration Systems. 1. Increase dissolved oxygen in water and provide oxygen for water treatment microorganisms. 2. Increase the dissolved oxygen in water and provide oxidant oxygen for iron removal. 3. Increase the air content in the water. During the decompression process, air bubbles are formed on the surface of oil impurities and other surfaces to float them up for separation and removal. 4. Pretreatment, increase the oxygen content in the water, prevent water rancidity, form a certain stirring effect on the water, and prevent the deposition of substances in the water. There are many functions, according to different purposes, the role of aeration is different.
Why is Aeration necessary for Wastewater Treatment? What are the types of aerators used in wastewater treatment plants? What is the Effect of pre-aeration in start-up of wastewater treatment? 10-20 minutes of pre-aeration: 1. It can produce natural flocculation or biological flocculation, so that the small particles in the wastewater can be aggregated into large particles to facilitate sedimentation and separation; 2. Reducing substances in oxidizable wastewater; 3. Increase the dissolved oxygen in the wastewater, reduce the corruption of the wastewater, and improve the stability of the wastewater; 4. It can blow off the volatile matter dissolved in wastewater. All of the above can purify wastewater.
What are the uses of aeration of liquids? (1) Aeration in aquaculture. (2) Sewage treatment aeration, The goal is to obtain enough dissolved oxygen in the water. The process of dissolving oxygen or dissipating dissolved gases and volatile substances in water in contact with gas. In the activated sludge method of wastewater, the dissolved oxygen of the mixed liquid must be supplied by aeration method. The aeration methods used in the activated sludge aeration tank can be divided into two categories:
Bubble aeration method and surface aeration method.
