2021-10-24
The backwash blower is an essential core piece of equipment in the wastewater treatment process, directly determining the overall system's efficiency and energy consumption. Primarily used in biological wastewater treatment, the backwash blower increases the oxygen content in aeration tanks, thereby promoting the growth of aerobic microorganisms. These microorganisms decompose wastewater by metabolizing suspended solids, dissolved organic matter, and nutrients such as nitrogen and phosphorus, thus achieving the goal of wastewater treatment. It is a key piece of equipment in wastewater treatment plants.

The performance of the backwash blower directly affects the quality of the wastewater we treat and our energy consumption. Backwash blower It is more suitable for applications with low economic costs. The backwash blower is a constant-flow blower whose primary operating parameter is air volume. Its output pressure varies with changes in the pipeline and load, but its air volume remains relatively stable. Centrifugal blowers produce low air pressure; the air compression process typically involves several working impellers (or stages) driven by centrifugal force. Backwash blowers have higher pressure than centrifugal blowers. Backwash blowers are generally used in high-pressure wastewater treatment systems. When water depth and pressure are high, they can reliably ensure sufficient aeration. Ordinary centrifugal blowers cannot meet these requirements. Backwash blowers can be applied to large-scale wastewater treatment projects.
Backwash blowers can be used in many environments—not only for purifying water treatment plants and agitating sediments, but also for supporting combustion in incinerators and facilitating exhaust gas discharge.
When installed inside pipelines, it can promptly remove dust and iron powder generated during pipeline replacement or major repairs, and can also supply various coatings into the pipeline. It can serve as an air source for high-concentration ozone generators, and can also be used as a gas carrier for composting livestock and poultry manure, thereby accelerating the fermentation and composting process of such waste. Without a burner, high-pressure exhaust gases can be used to gasify and combust into tiny molecules.
Backwash blower It is renowned for its application in fishpond farming. It is used for feeding and mixing in various fish ponds, including those raising fish and crabs, as well as in aquariums and live-fish tanks.
The backwash blower is used for exhaust ventilation of paper in printing offices and can also be employed for separation, alignment, and distribution. It can serve as an air source for sandblasting machines and is suitable for demolding workpieces after they have been formed on presses. Drying operations on small-scale production lines can be carried out directly on the drying line. This gas is used to convey grains such as wheat that fall from rotary pilot valves, and it can also be utilized for transporting special gases like coal gas. It is employed in humidification devices designed to maintain stable indoor temperatures for textile mills, cigarette factories, and printing plants, as well as in antistatic power supplies.
The backwash blower, serving as the primary air source for the pneumatic lift pump, provides the driving force necessary for material transport, continuously conveying materials through the delivery pipeline to the desired height. The air pressure of the backwash blower typically ranges between 55 and 80 kilopascals, while the air volume depends on the lift pump's capacity. First, check whether the backwash blower is operating properly. The Boshan pump accessories provide the power needed to keep the materials constantly in a fluidized state. Usually, secondary air is also supplied by the backwash blower. However, in actual applications involving alumina transportation, due to the fine and dense nature of alumina particles, both primary and secondary air are supplied by the same equipment. This can lead to an uneven distribution of air pressure and air volume—primarily because the secondary air pressure is insufficient, causing the fluidized layer of alumina to be too low and preventing it from automatically flowing toward the vicinity of the delivery pipe’s nozzle, thus resulting in material accumulation inside the pump body.
