Aeration Blower – Reliable, Continuous Oxygen Delivery for Biological Treatment and Environmental Process Systems
Engineering & Application Overview
In biological purification like wastewater facilities, industrial effluent treatment systems or aquaculture operations, all those things depend on a core thing, which is continuously supplying sufficient oxygen to microorganisms. When the oxygen supply drops below the supply demand, the purification quality starts dropping immediately. As a result, ammonia levels rise, biological oxygen demand (BOD) removal drops and effluent compliance is at risk. If oxygen levels drop in fisheries, fish start dying within a few hours. The damage is increasing in every moment after dropping oxygen levels in these facilities.
Another big concern is a lion's share of the total electricity consumed goes to aeration itself in a general biological treatment facility. So, Aeration Blower efficiency has a vital role in this field.
The Aeration Blower is designed based on the three most important things of a biological process. The first one is operating stability: this blower needs to work 24/7 for 365 days with a full scale of daily and seasonal biological needs without sudden shutdowns.
The second one is flow-pressure matching: this blower needs to deliver the precise airflow with accurate pressure according to the specific aeration system geometry. Whatever it is, a shallow industrial treatment tank, oxidation ditch or surface aeration circuit.
The third one is maintaining low noise while operating: a precisely designed impeller with a large diameter and low speed keeps noise low. It's highly recommended for those treatment plants located near residential or commercial areas. Because the noise can be annoying at nighttime.
This unit is suitable for low pressure and massive volumes of aeration systems. Such as oxidation ditches, open surface aeration circuits, shallow diffused aeration basins, aquaculture oxygenation systems, and industrial biological treatment tanks. Engineers use a 4-pole, low-speed, and wide-diameter impeller for low noise. You can feel this blower is like a medical oxygen supply system. If the oxygen supply shuts down, many casualties happen; this is the same importance of this blower in industry. That's why it is designed for nonstop duty and reliability with efficiency for uninterrupted support of biological processes.
