The structure design of this series of injectors is made to enable flows to mix and interact rapidly.Due to its high efficiency, it is widely used as injection aerators in wastewater treatment processes.
Jet pump/eductor/ejector for various special purpose:
This serial of jet pumps covers a wide range of industries and civil applications. Various structures have been developed to meet diverse requirements. Liquid jets liquid(LJL),liquid jets gas(LJG),gas jets gas(GJG),gas jets solid(GJS)have been utilized to fulfill functions as slurry suctioning and conveying, vacuum pump, solid powder convey, heat recollection,...are just a little of their infinite applications.
Venturi Injector
Primary ejection
As illustrated by figures,pressurized motive flow (red color ) enters into a convergent nozzle in the injection chamber to form a high velocity jet stream, The vacuum produced by high velocity flow enable materials (blue color ) to be suctioned into the chamber and enters into the motive flow, results in forming a new mix fluid (green color). The mixture flows through diffuser toward the out let with reducing velocity and increasing pressure.
Secondary ejection
The fluid mixture from injector ejects into the pond/tank/pipe line,drawing 4-5 times quantity of flow around it, resulting a second mix and
Series of Venturi Injector for Wastewater Treatment
GW series venturi injectors provide water/wastewater industries with a new substitute to blower and mechanical aeration systems with the following advantages：
- Higher oxygen transfer efficiency, less gas delivery required, low power consumption
- Simple pipeline,less facility space taking
- Less maintenance, no fouling factor in design
- Prolonged using life without performance decline
- Whisper operation
- Applicable to complete innovation installation without draining water from aeration pond/tank
Applications:
- Aeration and sludge treatment
- Ozone addiction and off-gas reuse
- River, pond, lake, reoxygenation
- Aquatic and aquarium
Injector Aeration System
Injector shows different oxygen transfer capabilities when the gas source switches from natural breath to compressed air or to pure oxygen/oxygen enriched air.The amount of AOTR increase is considerably doubled or tripled
injector aeration system can be designed to satisfy oxygen requirements from low loading to full loading ,or even to excessive loading by using different gas source (natural breath, compressed air, oxygen / oxygen enriched air)
There are two type of nozzles can be used in deep water(4m and above) or shallow water(3m or bellow) respectively to ensure high oxygen transfer efficiency regardless how deep is the water. Customers need not to care about their water depth.
Secondary Ejection Nozzles
Function of secondary ejection nozzles:
1:To proceed further matter transfer driven by the concentration difference between mixture from the injector and water in ponds/tanks.
2:To do agitation in the ponds/tanks using residue water head from the injector.
To provide enough retention time:
A venturi type of cylinder plus to nozzle is designed to maintain contacting time of gas in water. This configuration will have the same effect as increasing the water depth.

Liquid Jets Liquid Eductor Applications
Boosting suction pressure of pumps- deep well water fetching
At the initial activation of mechanical pump, a by-pass water from the outlet of the pump jets through an eductor which entrains water and moves it to a point where the mechanical pump can lift water the remaining distance. Capacity of these apparatus depends on the lifting Height and the mechanical pumps.
Multi-nozzle dredging eductors
Where the entrained fluid contains mud or sand, multiple nozzles are used for the purpose. The motive water enters at radial direction and jets through annularly arranged nozzles and pulls muds and sands to move in middle flow at axial direction .This configuration can reduce friction loss of the flow. The capacity is relative to the contents of mud/sand, distance and height to deliver and motive pump. These eductors can be used as well to:Fish catching and transition;Priming of large mechanical pump where there is air pockets;

Liquid Jets Gas Eductor Applications
Gas evacuation:
In many industries and civil practices there are needs to evacuate gas from hermetic space. Priming of centrifugal pump with LJG eductor is one of the various uses. The volume being primed are generally small, so a small quantity of fluid (pressurized water/air)can be applied as motive flow of the eductor.GW LJG eductor is also a safe option where it is dangerous to use power driven exhaust.
Maintaining pressure:
Some apparatus need to keep their internal pressure within a certain extend during operation, meanwhile, there is gas produced or entrained during the process. In this case, GW LJG can be utilized to exhaust gas and keep the pressure at the expected value. The above figure shows an example which is a MBR apparatus for wastewater treatment: When pressure rises in the gas-water separator, a differential pressure signal is given to a motive flow valve which automatically opens and the LJG eductor is activated to draw gas from the separator until the pressure drops to the minus desired point. This configuration not only saves space and investment but also energy since the driving fluid sources (pressure air/water)are always available on-site

Steam Ejecting Vacuum Pump
Steam ejects through an expanding nozzle which converts steam's pressure energy into spraying speed, creating a vacuum. Gases or other fluid materials are entrained into the mixing throat and impelled to diffuser where kinetic energy turned back to a pressure which is enough for the mixture to overcome predetermined back pressure and discharge. Besides functioning as vacuum pump, this characteristic has found steam jet a wide utilizations as degass, absorption, distillation, drying, filtration, heat transferring, etc.
