If the sewage treatment industry wants to save energy and protect the environment, it generally needs to be carried out from two levels. One is the selection of production processes, and the other is the selection of machinery and equipment. Most of the sewage treatment plants currently in use in my country use the activated sludge aerobic process. Blast aeration sends compressed air into the aeration tank through pipes and disperses it into the mixed liquid in the form of bubbles, allowing the oxygen in the bubbles to quickly diffuse and transfer into the mixed liquid, supplying activated sludge microorganisms and preventing the deposition of sludge.

Zhongjia magnetic levitation blower is a new type of blower that uses an active magnetic levitation bearing system to provide non-contact and wear-free suspension support to the blower through controllable electromagnetic force, eliminating the need for extra transmission links between the rotor and impeller. To low vibration and low noise.

The energy consumption of the blower in the sewage treatment plant accounts for approximately 30% to 50% of the total energy consumption of the entire sewage treatment plant. Compared with other fans, Zhongjia Control Maglev Blower has the characteristics of high efficiency, energy saving, long life, low noise and no attenuation.

High efficiency and energy saving: Compared with Roots blowers, using Zhongjia Control 150kw magnetic levitation blowers saves approximately 209,100 yuan in annual costs.

Assuming that the original fan is 150kw and the load rate is 85%, the power saving rate of Zhongjia magnetic levitation blower is calculated as 30%: 150 (kw) × 85% (load rate) × 30% (power saving rate) = 38.25kw; electricity saving is 38.25 per hour. degree; daily electricity cost savings of 572.74 yuan; annual electricity cost savings of 209,100 yuan. Source of electricity price data: electricity price in a county in Luoyang.

Long life: Roots blowers have a life of 3-5 years, and magnetic levitation blowers have a life of up to 20 years. Maintenance is simple and no lubricating oil, cleaning fees, etc. are required.

Low noise: The magnetic levitation motor rotates without friction and low noise.

No degradation: Traditional fan bearings wear and tear and performance degrades continuously.

Therefore, choosing Zhongjia controlled magnetic levitation blower as aeration equipment is particularly important in saving costs in sewage treatment plants.
