Wastewater aeration is the process of adding air into wastewater to allow aerobic bio-degradation of the pollutant components. It is an integral part of most biological wastewater treatment systems. Unlike chemical treatment which uses chemicals to react and stabilise contaminants in the wastewater stream, biological treatment uses microorganisms that occur naturally in wastewater to degrade wastewater contaminants.
Aeration is part of the stage known as the secondary treatment process. The activated sludge process is the most common option in secondary treatment for municipal and industrial waste water. Aeration in an activated sludge process is based on pumping air into a tank, which promotes the microbial growth in the wastewater. The microbes feed on the organic material, forming flocs which can easily settle out. After settling in a separate settling tank, bacteria forming the "activated sludge" flocs are continually recirculated back to the aeration basin to increase the rate of decomposition.
Aeration is the most critical component of a treatment system using the activated sludge process also the key of success for effective waste water treatment. A well designed aeration system has a direct impact on the level of wastewater treatment it achieves.
Water aeration equipment is uniquely designed with the customer in mind to improve wastewater quality and minimize operational expenses. Our aerators are used in a range of municipal and industrial wastewater treatment facilities. Our products are designed to be durable and rugged, providing you with trouble-free operation for the life of the equipment.
