Vacuum Tanks
Emptying the Tank
You can either empty the tank via impeller or pressure.
The pressure method uses the vacuum pump. The diverter level is used to direct the air
from outside into the tank to build up pressure. Then, when you open the rear valve, the pressure
forces the liquid
out of the tank. The alternative is to mount a hydraulically
operated impeller that will sling the effluent out of the tank.
Below, you will find a picture of the impeller system and regular non-impeller discharge
There are several advantages to using an impeller system over a pressure system...
- Saves wear and tear on the vacuum pump
- Provides for a faster, more consistent discarge
- Enables the use a flow control system
You also have two methods of applying the liquid
Spraying the manure on top
This involves using a spray deflector and just spreading the manure in an arching pattern on top of the soil.Injecting the manure
This is the recommended method. You use an injector to apply the manure underground. This has many advantages such as reducing smell, and utilizing nitrogen better.
