The upper tank is installed with manholes, breathing valve,top filling and ventilation can be   conducted through the manhole. The manhole can also enable the operators to enter the tank for maintenance and cleaning,and the breathing valve can keep the pressure balance between internal and external tank so as to prevent the tank pressure from being too high or too low, even damaging the tank.
