TRN Series is a submersible self aspirating aerator design for aeration and mixing of wastewater.  The liquid flow causes negative pressure to form on the backside of the impeller vanes and draw in air from the above water's surface. The aspirated air, mixed with water viciously by mechanical force inside the impeller and guide vane, transform into tiny bubbles. The mixed flow of air and water then evenly discharged in multiple directions along the circumference. The compounded action of the air lift and convective currents that are generated in the process makes aeration and agitation very efficient and increases the amount of oxygen dissolved in the water. read more
