In past few decades industrial manufacturing sector has grown with a rapid pace leading to higher living standards. This has also led to major problem by form industrial effluent and household sewage. Vast quantities of waste water have damaged the eco system and polluted our water source to a great extent. Toshio Technology has been making every endeavor in developing the waste water treatment equipment. In addition to waste water pumps and sewage pumps, the company has developed submersible aerator for efficient treatment rate of waste water. These aerators have been widely used in domestic and overseas waste water treatment plants.
JA series Submersible Jet Aerator Self-aspirating Submersible Aerators are applicable for aeration & mixing of waste water in treatment plant. Special design of the impeller generates strong jet flow of water mixed with air & supplies oxygen into wastewater.
Designed for living wastewater, wastewater treatment, supplies the oxygen for aeration and agitation, to bring the water current in foundation pools or water tanks to help avoid accumulation on the of tank and pool.

High oxygen transfer rate.
Biochemical oxygen demand easy to remove from wastewater treatment.
Provide coarse/gross bubbles.
Easy reduction of BOD level from waste water.
Submersible ejector can operates at a water depth of approximately 4-5 m, allowing efficient utilization of the treatment plant site.
It adopts a vortex flow-type impeller which facilitates good solid passage.
Uniform distribution of MLSS concentration.Firstly, water jet flow mix the bottom of the tank, and then micro bubbles are distributed to mix the tank in the upper direction, resulting in an extremely uniform distribution of MLSS concentration in the tank.
The guide rail type is easy to maintenance. Installation is also easy as submersible pumps, as the air suction pipe is also used as a guide rail.
Submersible ejector is a low noise structure, so that it can be installed wherever you want. And as no sound proof chamber is required, thereby reducing the construction cost.
There are two methods for selecting a submersible ejector: One is to determine the number of units based on Max. Capacity of Tank and the other is to determine the number of units based on the Tank Surface Area. The numbers of required units calculated by the respective methods normally differ because of constant variation in the water level in the flow regulating tank. Select a large number of units, carefully examine whether aeration is sufficient or not, and then select finally the type of pump and the number of units.
When determining a type of ejector and the number of units, Max. Water Depth and the tank shape should be
Considered. The followings are the pump selection procedures and calculation examples:
